AdjustSizeValue¶: Updates the width and height of this control according to its current style

AdjustType¶: Determines if and how the width and height of this control should be modified to take the fixed space dictated by the style of this control

ApplyStyleLookup()¶: Gets and applies the style of a TStyledControl.

AutoSize¶

Specifies whether TTabItem header (where the TabItem names appear) is auto-sized based on the length of the Text. Set the AutoSize property to True to automatically resize the tab item header according to the length of the Text. Set the AutoSize property to False to lock autoresize of the TTabItem header.

Tip: The size of the TTabItem header readjusts when the Font property changes.

Type:: bool

AutoTranslate¶: Specifies whether the control’s text should be translated

CanFocus¶

Specifies whether the current control can receive focus. CanFocus is True if it can receive focus, and False otherwise. If it is set to False, the control cannot be selected when using the TAB key. A control can receive focus after it is created.

Type:: bool

ClipChildren¶

Specifies if children of the control should be clipped to the control’s on-screen region. Set ClipChildren to

True if you want child controls to be clipped to the control’s on-screen region. False if you want child controls to be able to extend beyond the region of the parent control.

Type:: bool

ClipParent¶

Specifies whether the current control has clipped its parent. When ClipParent is True, TControl cuts off the portion of the parent that lies under the control when the control is painted by the Paint and Painting methods. Parts of the control that do not contain visible objects cut off holes in the parent’s image. ClipParent is ignored in PaintChildren and other painting methods. If one parent has more that one child control having ClipParent equals True, then only one of these child controls is painted with ClipParent equals True. Others child controls are painted as if ClipParent equals False.

Type:: bool

Cursor¶

Image to use to represent the mouse pointer when it passes into the region covered by the control. Change the value of Cursor to provide feedback to the user when the mouse pointer enters the control. For a list of cursor constants, see System.UITypes Constants. The image representations of the cursor depend on the theme active on the current platform. If Cursor is set to the default cursor, this control might display a different cursor when the mouse pointer is over it. The actual cursor that this control displays is the cursor defined in InheritedCursor, a read-only property that is calculated based not only in the value of Cursor in this control, but also the value of Cursor in any ancestor of this control (parent, grand-parent, and so on until the parent form).

Type:: int

CustomIcon¶

Specifies custom multi-resolution icons for the tab. This property is of the TFixedMultiResBitmap type. A TFixedMultiResBitmap multi-resolution bitmap represents a collection of TFixedBitmapItem bitmap items displayed at different scales. You can create a multi-resolution bitmap with the MultiResBitmap Editor. Mobile applications need to have images of different scales defined for various devices, such as Retina and non-Retina iOS devices.

Type:: FixedMultiResBitmap

DefaultStyleLookupName¶: Returns a string with the name of the default style of this control

DragMode¶

Specifies how the control initiates drag-and-drop operations. Use DragMode to control when the user can drag the control. Disable the drag-and-drop capability at run time by setting the DragMode property value to dmManual. Enable automatic dragging by setting DragMode to dmAutomatic.

Type:: DragMode

EnableDragHighlight¶

Specifies whether the control is highlighted when the dragged object is over it.

Type:: bool

Enabled¶

Specifies 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. This property applies to all TControl descendants.

Type:: bool

Font¶

Specifies the font to use when rendering the text. Set Font to specify the font to use when rendering the text. To change to a new font, specify a new TFont object. To modify a font, change the value of the Family, Size, or Style of the TFont object.

Type:: Font

GetTabList()¶: Embarcadero Technologies does not currently have any additional information.

Height¶

Height specifies the vertical size of the control (in dp). Use the Height property to read or change the height of the control.

Type:: float

HelpContext¶

Contains the numeric context ID that identifies the Help topic for the control. In case of a .chm Help file, you must symbolically map Context IDs of Help topics to numeric topic ID values in the [MAP] section of your project (.hhp) file. To enable Context ID-based context-sensitive Help for a control, set HelpType to htContext and set HelpContext to a numeric topic ID. A topic ID of 0 (default) means that no Help topic is provided for the control.

Type:: int

HelpKeyword¶

Contains the keyword string that identifies the Help topic for the control. To enable the keyword-based context-sensitive Help for a control, set the HelpType property to htKeyword and set HelpKeyword to a keyword string. No keyword (zero-length string, the default) means that no Help topic is provided for the control.

Type:: str

HelpType¶

Specifies whether the control’s context-sensitive Help topic is identified by a context ID or by keyword. If HelpType is htContext, the HelpContext property value identifies the control’s Help topic. If HelpType is htKeyword, the HelpKeyword property value identifies the control’s Help topic.

Type:: HelpType

HitTest¶

Enables the control to capture mouse events.

If you set HitTest to True, this control captures all mouse events. The example below shows the use of HitTest for an OnClick event. If you set HitTest to False, the mouse events will pass through this control, so that a control laid out behind this one receives the mouse events instead of this control. Note: The HitTest enables all mouse-related events, which also include the display of Hints and Hint-related events. For most controls, HitTest is True by default. However, this is not true for all the controls. For example, for TLabel and TPathLabel, HitTest is False by default; these two controls do not capture the mouse-related events unless you set HitTest to True.

Example of HitTest 1. On a form, place a TPanel component. 2. Inside the panel, place a TPathLabel component. 3. Implement the OnClick event for both the TPanel and the TPathLabel:

procedure TForm1.Panel1Click(Sender: TObject); begin

ShowMessage(‘OnClick event fired for TPanel’);

end;

procedure TForm1.PathLabel1Click(Sender: TObject); begin

ShowMessage(‘OnClick event fired for TPathLabel’);

end;

Set the TPathLabel HitTest property to False (this is the default setting). Run the application and click the label. The OnClick event is fired for the panel (not the label).
Set the TPathLabel HitTest property to True. Run the application and click the label. The OnClick event is fired for the TPathLabel.

Type:: bool

ImageIndex¶

Defines the zero-based index enumerating images in the Images list of images. If you use a non-existing ImageIndex value to access an image in the Images list, then no image is retrieved and no exception is raised. The usual default value is -1. Call ImagesChanged when ImageIndex is changed.

Type:: int

Images¶

Defines the reference to a TCustomImageList list of images to be used to draw images on the component. If the TCustomImageList list is empty, then Images is nil/null. Call ImagesChanged when Images is changed.

Type:: CustomImageList

Index¶

Specifies the index of the child object in the children array attached to this object.

Type:: int

Inflate()¶: Call this procedure to get and apply its style lookup.

IsSelected¶

Property that has the True value when the TTabItem object is selected. IsSelected is a property of TTabItem that has the Boolean value True if the tab item is selected. Otherwise, it has the Boolean value False.

Type:: bool

Locked¶

Specifies whether the control is locked at design time. A locked control prohibits to move the control at design time, all the other properties can be modified at design time. To lock the control, set Locked to True. By default, Locked is False, and the control can be modified at design time.

Type:: bool

Margins¶

Aligns the component to the margins points of other components. The Margins of a control are the distances (in pixels) from each edge (top, left, bottom, right) to another control within the same Parent or to the edge of its Parent. The Margins add space to the outer side of the control. It only applies for controls that do not use TAlignLayout None and the components are located to each other. If a margin is not 0, no other control will come closer to the control than the specified distance. If the distance from a Parent edge to the corresponding control edge is smaller than the specified Margins for that edge, the control is repositioned and resized, if necessary, to maintain the specified distance. If the Margins control has zero values, RAD Studio uses the default values (Left=4, Top=4, Right=4, Bottom=4). You can also set your own Margins values. It only applies to the IDE control’s guidelines, when you are dragging control. But if you use Align=Client (for example), it will use the specified values in Margins. The following image shows how Padding and Margins properties affect alignment, position, and size of controls.

Type:: Bounds

NeedStyleLookup()¶: Call this procedure to indicate that this control requires to get and apply its style lookup.

OnDragDrop¶: Callable[[Object, DragObject, PointF], None]:

OnDragEnter¶: Callable[[Object, DragObject, PointF], None]:

OnDragOver¶: Callable[[Object, DragObject, PointF, DragOperation], None]:

OnPaint¶: Callable[[Object, Canvas, RectF], None]:

OnPainting¶: Callable[[Object, Canvas, RectF], None]:

Opacity¶

Specifies the control opacity. Set Opacity to customize the transparency of the current control. Opacity takes values between 0 and 1. If Opacity is 1, the control is completely opaque; if it is 0, the control is completely transparent. The values over 1 are treated as 1, and the ones under 0 are treated as 0. Opacity applies to the control’s children.

Type:: float

Padding¶

Aligns the component to the padding points of other components. The Padding of a control specifies how close, in pixels, the control’s children can come to each of its edges (top, left, bottom, right). Padding adds space to the inner side of the control. The control’s children are repositioned and resized, if necessary, to maintain the Padding. If the Padding control has zero values, RAD Studio uses the default values (Left=4, Top=4, Right=4, Bottom=4). You can also set your own Padding values. The following image shows how Padding and Margins properties affect alignment, position, and size of controls.

Note: Padding constraints do not work for TScrollBox, TListBox, TTreeView, and TGrid based controls.

Type:: Bounds

ParentShowHint¶

If True, the value of the ShowHint property of this control inherits the value of the ShowHint property of the parent control. See Using Hints to Show Contextual Help in a FireMonkey Application - Enabling Hints for a Control for more information.

Type:: bool

PopupMenu¶

Specifies the context (pop-up) menu object. Use PopupMenu to set the context menu of the current control. The pop-up window is displayed when ShowContextMenu is called.

Type:: CustomPopupMenu

Scale¶

Specifies the scale of the control. Set the Scale coordinates to specify the scale on each axis. The initial scale rate is 1 on each axis.

Note: Controls that have the Align or Anchors properties set can use a scale that is different from the default (1,1), so that controls align together even when they have a custom scale.

Type:: Position

ShowAsDot¶

If ShowAsDot is true, then the StyleLookup property has the value tabdotstyle.

Type:: bool

Size¶

Specifies the vertical and horizontal size (Size.Height and Size.Width) of the control (in pixels). Use the Size property to read or change the size of the control.

Type:: ControlSize

StyleLookup¶: Specifies the name of the resource object to which the current TStyledControl is linked

StyleState¶: This property allows you to define the current state of style

StyledSettings¶

Defines the set of styled text representation properties whose values are loaded from the current style and cannot be changed manually. Text representation properties are used as parameters for drawing texts in controls. The StyledSettings property is used in FMX controls such as TButton, TSpeedButton, TCheckBox, and others. Styles, for example Metropolis UI styles, define the default values of the text representation properties like font name, font size, word-wrapping, and others. The TTextSettings class define properties keeping values of the FontColor, TextAlign, VertTextAlign, Trimming, WordWrap, and Font (TFont.Family, TFont.Size, TFont.Style) elements defining visual parameters of a text representation. StyledSettings can contain the Family, Size, Style, FontColor, and Other values defined in TStyledSetting. The “Relation between TStyledSetting constants and TTextSettings properties” table shows which of the TStyledSetting constants control the handling of these TTextSettings text representation properties. Keep in mind that the values of all styled text representation properties listed in the StyledSettings are taken from a style and cannot be changed manually. For example, if you set a new value of the FontColor property of a TTextControl control, then the real updating of the font color takes place only if the StyledSettings property of this control does not contain TStyledSetting.FontColor. For more details, see the example in Setting Text Parameters in FireMonkey. To switch OFF a font property for a control, select the control in the Form Designer. In the Object Inspector, expand the StyledSettings property. Clear the check mark before the property. For example, the following figure shows a TButton control with Size turned OFF (for Button1) and ON (for Button2):

With StyledSettings you can also use the DefaultStyledSettings constant that defines the values of the styled properties that are taken from a style by default. Remember that the HorzAlign and VertAlign text representation properties stored in the TextSettings property of a control correspond to the TextAlign and VertTextAlign properties of the control.

Type:: StyledSettings

TabControl¶

Returns a TTabControl object that holds this tab page.

Note: You cannot access this TTabControl using the TTabItem.Parent property.

Type:: TabControl

TabOrder¶

Indicates the position of the control in its parent’s tab order. TabOrder is the order in which child controls 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. 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 ensures that the control is the last in the tab order.

Type:: int

TabStop¶

Embarcadero Technologies does not currently have any additional information.

Type:: bool

Text¶

Specifies the text that will be rendered over the surface of this TTextControl object. Set the Text property to specify the text that will be displayed by this TTextControl. Text can be any string. If there are any effects already applied before changing the Text property, they will be preserved for the new text. Also, the surface of this TTextControl is repainted. In the Text property you can define an accelerator key. On Windows platforms, an accelerator key is shown as an underlined letter. To specify an accelerator key, precede an <accelerator_letter> with an ampersand & character. The letter after the ampersand appears underlined. For example, to set the S character as an accelerator key for a Save button, type &Save. On Windows platforms, accelerator keys enable the user to access controls pressing Alt+<accelerator_letter> key combination. When run on not Windows platforms, a single ampersand is simply stripped from the text. To show a single ampersand & character in a Text property specify doubled ampersand && characters.

Tip: If you specify a new text string that is exactly the same as the one already displayed, the effects will not be re-updated and this TTextControl object will not be repainted. Note: FMX.ExtCtrls.TPopupBox.Text is not a writable property in the same way as FMX.Controls.TTextControl.Text. The FMX.ExtCtrls.TPopupBox.Text property cannot be “any string”, but instead must be just one of the strings in the FMX.ExtCtrls.TPopupBox.Items property and, in this case, FMX.ExtCtrls.TPopupBox.ItemIndex is updated accordingly.

Type:: str

TextAlign¶

Specifies how the text will be displayed in terms of horizontal alignment. The TextAlign property specifies how the TTextControl object will display the text in terms of horizontal alignment. TextAlign can have one of the following values (defined in TTextAlign):

Center (default)–aligns the text on a horizontal axis, at the middle of the TTextControl object. Leading–aligns the text on a horizontal axis, at the leftmost position inside the TTextControl object. Trailing–aligns the text on a horizontal axis, at the rightmost position inside the TTextControl object. When you use text representation properties stored in ITextSettings.TextSettings, remember that TextAlign corresponds to HorzAlign.

Type:: TextAlign

TextSettings¶

Keeps the values of styled text representation properties that are set in the Object Inspector or programmatically. TextSettings references a TTextSettings type object that handles values of styled text representation properties that are set in the Object Inspector or programmatically. TextSettings references a TTextSettings type object, which handles styled text representation properties to be used for drawing texts in this control. TTextSettings type objects provide all styled text representation properties and methods to manage them. The styled text representation properties are FontColor, TextAlign, VertTextAlign, Trimming, WordWrap, and Font (TFont.Family, TFont.Size, and TFont.Style). TTextSettings objects provide both styled text representation properties, whose values are loaded from a style (specified in StyledSettings), so all other styled text representation properties, whose values can be set manually, and methods to manage these text representation properties. The text representation properties identified in StyledSettings are loaded from the style and cannot be set manually. Remember that the HorzAlign and VertAlign text representation properties stored in the TextSettings property of a control correspond to the TextAlign and VertTextAlign properties of the control.

Type:: TextSettings

TouchTargetExpansion¶

Set of optional pixel values you can specify to expand the touch target of a FireMonkey styled control. FMX.Controls.TControl.TouchTargetExpansion is a published property of all FireMonkey styled controls that support Touch. Defined as an FMX.Types.TBounds, TouchTargetExpansion takes four optional parameters representing the expansion of the four sides of the control in pixels (Bottom, Left, Right, Top). Each parameter specifies the size of an additional screen area that is to be treated as part of the touch target of the control. The following figure illustrates how TouchTargetExpansion expands the touch target for a FireMonkey control:

Type:: Bounds

Trimming¶

Specifies the behavior of the text, when it overflows the area for drawing the text. Trimming may take the following values defined in the TTextTrimming type: None, Character, and Word. If the value of this property is not None and the text does not fit in the drawing area, then it is trimmed to fit the area and an ellipsis sign is printed after the trimmed text.

Note: Under the iOS platform, Trimming works only when WordWrap = False.

Type:: TextTrimming

VertTextAlign¶

Specifies how the text will be displayed in terms of vertical alignment. The VertTextAlign property specifies how the TTextControl control displays the text in terms of vertical alignment. VertTextAlign can have one of the following values (defined in TTextAlign):

Center (default)–aligns the text on a vertical axis, at the middle of the TTextControl object. Leading–aligns the text on a vertical axis, at the topmost position inside the TTextControl object. Trailing–aligns the text on a vertical axis, at the bottommost position inside the TTextControl object. When you use text representation properties stored in ITextSettings.TextSettings, remember that VertTextAlign corresponds to VertAlign.

Type:: TextAlign

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.

Type:: bool

Width¶

Specifies the horizontal size of the control (in pixels). Use the Width property to read or change the width of the control.

Type:: float

WordWrap¶

Specifies whether the text inside the TTextControl object wraps when it is longer than the width of the control. Set WordWrap to True to allow the TTextControl control to display multiple lines of text. When WordWrap is True, text that is too long for the TTextControl object wraps at the right margin and continues in additional lines. Set WordWrap to False for the text to span onto a single line of the TTextControl. However, in this case, the text that is too long for TTextControl appears truncated. The default value for the WordWrap property is False.

Type:: bool
