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

Caption#

Specifies a text string that identifies the control to the user. Use Caption to specify the text string that labels the control. To underline a character in a Caption that labels a component, include an ampersand (&) before the character. This type of character is called an accelerator character. The user can then select the component by pressing ALT while typing the underlined character. To display an ampersand character in the caption, use two ampersands (&&).

Notes: Controls that display text use either the Caption property or the Text property to specify the text value. The property that is used depends on the type of control. In general, Caption is used for text that appears as a window title or label, while Text is used for text that appears as the content of a control. For some controls, such as TButton, it is not possible to change the color of the Caption. If you want to change the color of a button caption, you should use an alternate button type such as TSpeedButton or TBitBtn instead of TButton. With either TSpeedButton or TBitBtn, you can change the color of the Caption property by using the Font property. For TLinkLabel, an HTML tag is declared inside the Caption property either at run time or at design time.

ControlCount#: Returns the count of contained controls

Controls#: Returns an iterator over contained controls

Create(AOwner: Component)#

Creates an instance of TCustomControl. Vcl.ExtCtrls.TPage.Create inherits from Vcl.Controls.TCustomControl.Create. All content below this line refers to Vcl.Controls.TCustomControl.Create. Creates an instance of TCustomControl. Calling Create constructs and initializes an instance of TCustomControl. However, you should never attempt to instantiate a TCustomControl. This class is intended solely as a base class from which other control classes descend and you should only call Create to instantiate one of these descendants. Controls placed on forms at design time are created automatically. After calling the inherited constructor, Create initializes the control and also a TCanvas object for its Canvas property. When overriding Create, always call the inherited Create method first, then proceed with the control’s initialization. Remember to specify the override directive when overriding the Create method.

Note: If a component’s constructor allocates resources or memory, also override the destructor to free those resources.

Focused#: Determines whether the control has input focus.

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

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

Height#: Specifies the vertical size of the control in pixels. Use the Height property to read or change the height of the control.

OnAlignInsertBefore#: <Delphi property OnAlignInsertBefore of type TPage at 21141909CF0>

OnAlignPosition#: <Delphi property OnAlignPosition of type TPage at 21141909DC0>

OnGesture#: <Delphi property OnGesture of type TPage at 21141909E90>

ParentWindow#: Reference to parent’s underlying control.

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

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

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.

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.

Width#

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

Note: For tab sheet controls, changing this property at run time has no effect.
