DateTimePicker#

Qualified name: delphivcl.DateTimePicker

class DateTimePicker#

Bases: WinControl

TDateTimePicker displays a list box for entering dates or times. TDateTimePicker is a visual component designed specifically for entering dates or times. In dmComboBox date mode, it resembles a list box or combo box, except that the drop-down list is replaced with a calendar illustration; users can select a date from the calendar. Dates or times can also be selected by scrolling with Up and Down arrows and by typing. Date-time picker ignores the BiDiMode setting for right-to-left reading, displaying dates according to the system locale. TDateTimePicker formats date and time values according to the date and time settings in the Regional Settings of the Control panel on the user’s system. Because TDateTimePicker is a wrapper for a Windows control, these formats can’t be changed by changing the formatting variables in the SysUtils unit. However, you can use the Windows API call DateTime_SetFormat to programmatically specify these settings.

Note: The underlying Windows control is known to behave unpredictably when used to set dates in 1752, the year English-speaking countries changed to the Gregorian calendar. Similar problems may appear for different dates when a non-English locale is used. If an application might be used to specify dates on or before the changeover in the current locale (for example, 1918 or before in Russian locales), be sure to test the application using the dates affected.

Align#

Determines how the control aligns within its container (parent control). Use Align to align a control to the top, bottom, left, or right of a form or panel and have it remain there even if the size of the form, panel, or component that contains the control changes. When the parent is resized, an aligned control also resizes so that it continues to span the top, bottom, left, or right edge of the parent. For example, to use a panel component with various controls on it as a tool palette, change the panel’s Align value to alLeft. The value of alLeft for the Align property of the panel guarantees that the tool palette remains on the left side of the form and always equals the client height of the form. The default value of Align is alNone, which means a control remains where it is positioned on a form or panel.

Tip: If Align is set to alClient, the control fills the entire client area so that it is impossible to select the parent form by clicking it. In this case, select the parent by selecting the control on the form and pressing ESC, or by using the Object Inspector. Any number of child components within a single parent can have the same Align value, in which case they stack up along the edge of the parent. The child controls stack up in z-order. To adjust the order in which the controls stack up, drag the controls into their desired positions.

Note: To cause a control to maintain a specified relationship with an edge of its parent, but not necessarily lie along one edge of the parent, use the Anchors property instead.

Anchors#

Specifies how the control is anchored to its parent. Use Anchors to ensure that a control maintains its current position relative to an edge of its parent, even if the parent is resized. When its parent is resized, the control holds its position relative to the edges to which it is anchored. If a control is anchored to opposite edges of its parent, the control stretches when its parent is resized. For example, if a control has its Anchors property set to [akLeft, akRight], the control stretches when the width of its parent changes. Anchors is enforced only when the parent is resized. Thus, for example, if a control is anchored to opposite edges of a form at design time and the form is created in a maximized state, the control is not stretched because the form is not resized after the control is created.

Note: If a control should maintain contact with three edges of its parent (hugging one side of the parent and stretching the length of that side), use the Align property instead. Unlike Anchors, Align allows controls to adjust to changes in the size of other aligned sibling controls as well as changes to the parent’s size.

BevelEdges#: Specifies which edges of the control are beveled. Use BevelEdges to get or set which edges of the control are beveled. The BevelInner, BevelOuter, and BevelKind properties determine the appearance of the specified edges.

BevelInner#: Specifies the cut of the inner bevel. Use BevelInner to specify whether the inner bevel has a raised, lowered, or flat look. The inner bevel appears immediately inside the outer bevel. If there is no outer bevel (BevelOuter is bvNone), the inner bevel appears immediately inside the border.

BevelKind#: Specifies the control’s bevel style. Use BevelKind to modify the appearance of a bevel. BevelKind influences how sharply the bevel stands out. BevelKind, in combination with BevelWidth and the cut of the bevel specified by BevelInner or BevelOuter, can create a variety of effects. Experiment with various combinations to get the look you want.

BevelOuter#: Specifies the cut of the outer bevel. Use BevelOuter to specify whether the outer bevel has a raised, lowered, or flat look. The outer bevel appears immediately inside the border and outside the inner bevel.

BevelWidth#: Specifies the width of the inner and outer bevels. Use BevelWidth to specify the width, in pixels, of the inner and outer bevels.

BiDiMode#: Specifies the bidirectional mode for the control. Use BiDiMode to enable the control to adjust its appearance and behavior automatically when the application runs in a locale that reads from right to left instead of left to right. The bidirectional mode controls the reading order for the text, the placement of the vertical scroll bar, and whether the alignment is changed. Alignment does not change for controls that are known to contain number, date, time, or currency values. For example, with data-aware controls, the alignment does not change for the following field types: ftSmallint, ftInteger, ftWord, ftFloat, ftCurrency, ftBCD, ftDate, ftTime, ftDateTime, ftAutoInc.

CalAlignment#: Determines the alignment of the drop-down calendar. Set CalAlignment to dtaLeft or dtaRight to align the drop-down calendar on the left or right side of the component. This property is applicable only if the Kind property is dtkDate and the DateMode property is dmComboBox.

CalColors#: <Delphi property CalColors of type TDateTimePicker at 211414E73C0>

CanFocus()#: Indicates whether a control can receive focus.

Checked#: Indicates whether the check box next to the date or time is selected. Checked is true if the check box in the TDateTimePicker component is selected. Setting Checked to true at design time makes the check box appear selected by default.

Color#: Specifies the background color of the control. Use Color to read or change the background color of the control. If a control’s Vcl.Controls.TControl.ParentColor property is True, then changing the Color property of the control’s parent automatically changes the Color property of the control. When the value of the Color property is changed, the control’s ParentColor property is automatically set to False. The Color of a TLabel is always the color of the background unless you set TLabel.Transparent to False.

Constraints#

Specifies the size constraints for the control. Use Constraints to specify the minimum and maximum width and height of the control. When Constraints contains maximum or minimum values, the control cannot be resized to violate those constraints.

Note: Constraints apply to the height of the form. However, the height of the form depends on how large Windows makes the title bar. For example, Windows XP uses much larger title bars than other windowing systems. To work around this, note the ClientHeight when you design your form and set the constraints in the FormCreate event. In the following example, ClientHeight is represented by x: Constraints.MinHeight?:= x + Height - ClientHeight. Warning: Do not set up constraints that conflict with the value of the Align or Anchors property. When these properties conflict, the response of the control to resize attempts is not well-defined.

ControlCount#: Returns the count of contained controls

Controls#: Returns an iterator over contained controls

Create(AOwner: Component)#: Creates and initializes a TDateTimePicker instance. Create calls the inherited constructor method and initializes the Date and Time properties to the current date and time. It also sets the following ControlStyle flags: csCaptureMouse, csOpaque, csClickEvents, csDoubleClicks, and csFixedHeight.

Date#: <Delphi property Date of type TDateTimePicker at 211414E7560>

DateFormat#: Specifies format in which the date is presented. If DateFormat is set to dfShort, the date is formatted using the short date format specified in the Windows control panel. By default, it appears like this: 3/21/97. If DateFormat is set to dfLong, the date is formatted using the long date format specified in the Windows control panel. By default, it appears like this: Friday, March 21, 1997. (Applies only when Kind is dtkDate.) For custom date formats, set the Format property.

DateMode#: Determines the method of date selection used by the component. If DateMode is dmComboBox, the component has a drop-down calendar illustration from which the user can select a date. If DateMode is dmUpDown, the component has Up/Down arrows with which the user can adjust the date. (Applies only when Kind is dtkDate.)

DateTime#: <Delphi property DateTime of type TDateTimePicker at 211414E6AD0>

DoubleBuffered#

Determines whether the control’s image is rendered directly to the window or painted to an in-memory bitmap first. When DoubleBuffered is false, the windowed control paints itself directly to the window. When DoubleBuffered is true, the windowed control paints itself to an in-memory bitmap that is then used to paint the window. Double buffering reduces the amount of flicker when the control repaints, but is more memory intensive. When a windowed control is a dock site and has an associated dock manager, it must be double-buffered.

Note: Some controls, such as TRichEdit, can’t paint themselves into a bitmap. For such controls, DoubleBuffered must be set to false.

DragCursor#

Specifies the image used to represent the mouse pointer when the control is being dragged. Use the DragCursor property to change the cursor image presented when the control is being dragged.

Note: To make a custom cursor available for the DragCursor property, see the Cursor property.

DragKind#: Specifies whether the control is being dragged normally or for docking. Use DragKind to get or set whether the control participates in drag-and-drop operations or drag-and-dock operations.

DragMode#: Specifies how the control initiates drag-and-drop or drag-and-dock operations. Use DragMode to control when the user can drag the control. Disable the drag-and-drop or drag-and-dock capability at run time by setting the DragMode property value to dmManual. Enable automatic dragging by setting DragMode to dmAutomatic. For more information about dmManual and dmAutomatic, see TDragMode.

DroppedDown#: Specifies whether the date time picker control is dropped down. DroppedDown specifies whether the date time picker control is dropped down.

Enabled#

Controls whether the control responds to mouse, keyboard, and timer events. Use Enabled to change the availability of the control to the user. To disable a control, set Enabled to False. Some disabled controls appear dimmed (for example: buttons, check boxes, labels), while others (container controls) simply lose their functionality without changing their appearance. If Enabled is set to False, the control ignores mouse, keyboard, and timer events. To re-enable a control, set Enabled to True.

Note: This property applies to all TControl descendants.

Focused#: Determines whether the control has input focus.

Font#

Specifies the attributes of text written on or in the control. To change to a new font, specify a new TFont object. To modify a font, change the value of the Charset, Color, Height, Name , Pitch, Size, or Style of the TFont object.

Note: Changing the font color of the Caption is not supported for some controls (such as TButton). In most cases, there is an alternate control you can use whose Font property will change the color of the caption or text (such as TBitBtn or TSpeedButton).

Format#

Specify format for date-time string. Format specifies custom format string for the date-time display, overriding the control panel strings. A custom format can include both date and time fields, but time fields are not editable unless the Kind property is dtkTime. The following format characters are understood.

Element

Description

The one- or two-digit day.

The two-digit day. Single-digit day values are preceded by a zero.

ddd

The three-character weekday abbreviation.

dddd

The full weekday name.

The one- or two-digit hour in 12-hour format.

The two-digit hour in 12-hour format. Single-digit values are preceded by a zero.

The one- or two-digit hour in 24-hour format.

The two-digit hour in 24-hour format. Single-digit values are preceded by a zero.

The one- or two-digit minute.

The two-digit minute. Single-digit values are preceded by a zero.

The one- or two-digit month number.

The two-digit month number. Single-digit values are preceded by a zero.

MMM

The three-character month abbreviation.

MMMM

The full month name.

The one-letter AM/PM abbreviation (that is, AM is displayed as “A”).

The two-letter AM/PM abbreviation (that is, AM is displayed as “AM”).

The last two digits of the year (that is, 2001 would be displayed as “01”).

yyyy

The full year (that is, 2001 would be displayed as “2001”).

To include literal strings in the format, enclose them in single quotes. Failing to quote literal strings can have unpredictable results, even if they do not include formatting codes. Use two single quotes to represent one single quote character in a literal string. For example, Today’s date: MMM dd, yyyy entered in the property editor, produces the following results for April 1, 2001: “Today’s date: Apr 01, 2001”

Note: When setting Format programmatically in Delphi code, double each single quote again:

DateTimePicker1.Format := ‘’’Today’’’’s date:’’ MMM dd, yyyy’;

Handle#: Provides access to the underlying Windows screen object for the control.

HandleAllocated#: Reports whether a screen object handle exists for the control.

ImeMode#

Determines the behavior of the input method editor (IME). Set ImeMode to configure the way an IME processes user keystrokes. An IME is a front-end input processor for Asian language characters. The IME hooks all keyboard input, converts it to Asian characters in a conversion window, and sends the converted characters or strings on to the application. ImeMode allows a control to influence the type of conversion performed by the IME so that it is appropriate for the input expected by the control. For example, a control that only accepts numeric input might specify an ImeMode of imClose, as no conversion is necessary for numeric input.

Note: The value of ImeMode only takes effect when the control receives focus. To change the value of ImeMode when the control already has input focus, call the SetIme method.

ImeName#

Specifies the input method editor (IME) to use for converting keyboard input to Asian language characters. Set ImeName to specify which IME to use for converting keystrokes. An IME is a front-end input processor for Asian language characters. The IME hooks all keyboard input, converts it to Asian characters in a conversion window, and sends the converted characters or strings on to the application. ImeName must specify one of the IMEs that has been installed through the Windows control panel. The property inspector provides a drop-down list of all currently installed IMEs on the system. At runtime, applications can obtain a list of currently installed IMEs from the global Screen variable. If ImeName specifies an unavailable IME, the IME that was active when the application started is used instead. No exception is generated.

Note: The value of ImeName only takes effect when the control receives focus. To change the value of ImeName after the control has input focus, call the SetIme method.

Kind#: Determines whether the component is a date selector or a time selector. If the Kind property is dtkDate, the control is configured to support date editing. The default format gives only the date portion of the control value, and a drop-down calendar is available if the DateMode property is dmComboxBox. If the Kind property is dtkTime, the control is configured to support time editing. The default format give only the time portion of the control value, but the date portion can also be edited if the Format property includes date field codes..

ParentBiDiMode#: Specifies whether the control uses its parent’s BiDiMode. Use ParentBiDiMode to get or set whether the control uses its parent’s BiDiMode. When ParentBiDiMode is true, the control’s BiDiMode property is always equal to that of its parent. If ParentBiDiMode is false, the control uses its own BiDiMode property. Set ParentBiDiMode to true for all controls in a form to ensure that the entire user interface adjusts to Middle Eastern locales in a uniform manner. When the value of the control’s BiDiMode property changes, ParentBiDiMode becomes false automatically.

ParentColor#: Specifies where a control looks for its color information. To have a control use the same color as its parent control, set ParentColor to True. If ParentColor is False, the control uses its own Color property. Set ParentColor to True for all controls to ensure that all the controls on a form have a uniform appearance. For example, if ParentColor is True for all controls in a form, changing the background color of the form to gray causes all the controls on the form to also have a gray background. When the value of a control’s Color property changes, ParentColor becomes False automatically.

ParentDoubleBuffered#: ParentDoubleBuffered defers the DoubleBuffered property of this component to the value of the parent’s DoubleBuffered property. ParentDoubleBuffered is a boolean indicating that the DoubleBuffered property of this component is overridden by the value of the parent’s DoubleBuffered property.

ParentFont#: Specifies where a control looks for its font information. To have a control use the same font as its parent control, set ParentFont to true. If ParentFont is false, the control uses its own Font property. Many controls default ParentFont to true so that all the controls in a form or other container present a uniform appearance. When the value of a control’s Font property changes, ParentFont becomes false automatically. When ParentFont is true for a form, the form uses the default font. Currently, the default font is Tahoma 8 pt.

ParentShowHint#

Specifies where a control looks to find out if its Help Hint should be shown. Use ParentShowHint to ensure that all the controls on a form either uniformly show their Help Hints or uniformly do not show them. If ParentShowHint is True, the control uses the ShowHint property value of its parent. If ParentShowHint is False, the control uses the value of its own ShowHint property. To provide Help Hints only for selected controls on a form, set the ShowHint property for those controls that should have Help Hints to True, and ParentShowHint becomes False automatically.

Note: Enable or disable all Help Hints for the entire application using the ShowHint property of the application object.

ParentWindow#: Reference to parent’s underlying control.

ParseInput#: Enables the OnUserInput event. If ParseInput is True, the OnUserInput event occurs whenever the user types into the component’s edit box.

PopupMenu#: Specifies the pop-up menu associated with the control. Assign a value to PopupMenu to make a pop-up menu appear when the user selects the control and clicks the right mouse button. If the TPopupMenu’s AutoPopup property is True, the pop-up menu appears automatically. If the menu’s AutoPopup property is False, display the menu with a call to its Popup method from the control’s OnContextPopup event handler.

SetFocus()#: Gives the input focus to the control.

ShowCheckbox#: Displays a check box next to the date or time. Set ShowCheckbox to true to display a check box in the TDateTimePicker component.

ShowHint#

ShowHint specifies whether to show the Help Hint when the mouse pointer moves over the control. ShowHint determines whether the Help Hint appears for the control. The Help Hint is the value of the TControl.Hint property. The Help Hint appears in a box just beneath the control when the mouse pointer moves over the control. To enable Help Hints for a particular control, two conditions must be satisfied:

The application’s ShowHint property must be True. Either the control’s own ShowHint property must be True, or the control’s ParentShowHint property must be True and its parent’s ShowHint property must be True. For example, imagine a check box within a group box. If the ShowHint property of the group box is True and the ParentShowHint property of the check box is True, but the ShowHint property of the check box is False, the check box still displays its Help Hint. Changing the ShowHint value automatically sets the ParentShowHint property to False.

Showing#: Indicates whether the control is showing on the screen.

StyleElements#: Specifies the style elements that are used by the control. Use StyleElements to customize the style of the control. If a custom style is enabled, you can enable or disable style elements in the control. StyleElements is a set of values that specify which elements of the current style are to be applied to this control. By default, all the elements of the style are enabled.

StyleName#: Embarcadero Technologies does not currently have any additional information.

TabOrder#

Indicates the position of the control in its parent’s tab order. TabOrder is the order in which child windows are visited when the user presses the Tab key. The control with the TabOrder value of 0 is the control that has the focus when the form first appears. Initially, the tab order is always the order in which the controls were added to the form. The first control added to the form has a TabOrder value of 0, the second is 1, the third is 2, and so on. Change this by changing the TabOrder property. Each control has a unique tab-order value within its parent. If you change the TabOrder property value of one control to be the same as the value of a second control, the TabOrder value for all the other controls changes. For example, suppose a control is sixth in the tab order. If you change the control’s TabOrder property value to 3 (making the control fourth in the tab order), the control that was originally fourth in the tab order now becomes fifth, and the control that was fifth becomes sixth. Assigning TabOrder a value greater than the number of controls contained in the parent control moves the control to the end of the tab order. The control does not take on the assigned value of TabOrder, but instead is given the number that assures the control is the last in the tab order.

Note: TabOrder is meaningful only if the TabStop property is True and if the control has a parent. (The TabOrder property of a form is not used unless the form is the child of another form.) A control with a TabOrder of -1 has no parent, and therefore cannot be reached by pressing the Tab key. To remove a parented control from the Tab order, set its TabStop property to False.

TabStop#

Determines whether the user can tab to a control. Use the TabStop to allow or disallow access to the control using the Tab key. If TabStop is True, the control is in the tab order. If TabStop is False, the control is not in the tab order and the user cannot press the TAB key to move to the control.

Note: TabStop is not meaningful for a form unless the form assigns another form to be its parent.

Time#: Indicates the time entered by the user. Time represents the time entered by the user. Set Time in program code or in the Object Inspector to determine which time is selected by default. (Applies only when Kind = dtkTime.)

Touch#

Specifies the touch manager component associated with the control. Use the Touch property to access gesturing options associated with a control. Touch specifies a class of type TTouchManager. Touch is used to:

Associate a TGestureManager. (TGestureManager manages all the gestures that can be used by the control.) Select the standard, interactive, or custom gestures to associate with the control. (You can also connect each gesture to an action; see Assigning Actions to Gestures.) Specify a set of options for interactive or tablet gestures.

Visible#: Specifies whether the component appears onscreen. Use the Visible property to control the visibility of the control at run time. If Visible is True, the control appears. If Visible is False, the control is not visible. Calling the Show method sets the control’s Visible property to True. Calling the Hide method sets it to False. For TCustomForm descendants, the Show and ShowModal methods set Visible to True and bring the form to the front of all open windows. For TTabSheet descendants, Visible does not control the visibility of the control at run time. For more information, see the description of the TabVisible property.
