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

Align

Specifies the alignment options (top, left, client, and so on) of this control. Use Align to automatically set the alignment of the current control. Setting Align to a value different than None can affect the position, size (height and width), and anchors of the control. By default, Align is set to None. Descendants of TControl typically set the visibility and value for the Align property. For example, for TToolBar, Align defaults to TAlignLayout.Top. To see the possible values for Align and their visible effects over the control, see FMX.Types.TAlignLayout. 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:

AlignLayout

Anchors

Specifies how the control is anchored to its parent. Use Anchors to ensure that a control maintains its current position relative to the edges 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. Anchors is enforced only when the parent control is resized. If a control is anchored to opposite edges at the same time, the control stretches horizontally or vertically to maintain constant the distance between the control edges and parent edges. If a control is anchored to all four edges of its parent, the control stretches in all directions. By default, a control is anchored to the top and left edges of its container (Anchors=[akTop,akLeft]). The automatic alignment may affect the anchors of a control. When Align is set to None, all the anchors are available. If Align is not None, the anchors affected by the automatic alignment are excluded. Changing the state of the anchors affected by the automatic alignment has no effect over the control. 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:

Anchors

ApplyStyleLookup()

Gets and applies the style of a TStyledControl.

AutoCalculateContentSize

Indicates that the size of the scrolling content is calculated automatically according to the size of the components in content. Otherwise, the value of the ContentSize property defines the content size.

Type:

bool

AutoHide

Defines that scrollbars hide automatically when you scroll. AutoHide can be used to force the scrollbars to display.

Type:

BehaviorBoolean

AutoTranslate

Specifies whether the control’s text should be translated

Bounces

Indicates if it is possible to scroll content abroad.

Type:

BehaviorBoolean

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

ContentSize

Current content size.

Type:

ScrollContentSize

ControlType

ControlType:

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

DefaultStyleLookupName

Returns a string with the name of the default style of this control

DisableMouseWheel

Defines that the control does not have reaction to Mouse-Wheel event.

Type:

bool

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

EnabledScroll

Enables or disables scrolling.

Type:

bool

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

Hint

Specifies the text string that appears when the user moves the mouse over a control. See Using Hints to Show Contextual Help in a FireMonkey Application for more information about hints.

Type:

str

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;

4. 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).

5. Set the TPathLabel HitTest property to True. Run the application and click the label. The OnClick event is fired for the TPathLabel.

Type:

bool

Inflate()

Call this procedure to get and apply its style lookup.

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.

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

Position

Aligns the component to the position points of other components (Bounds points). Specifies the upper-left corner of the current control, relative to its parent. The Position can be affected by the Padding of its parent and the Margins of the control.

Type:

Position

RotationAngle

Specifies the amount (in degrees) by which the control is rotated from the x-axis. Positive angles correspond to clockwise rotation. For counterclockwise rotation, use negative values. To set the rotation center, use RotationCenter.

Type:

float

RotationCenter

Specifies the position of the pivot point of the control. The coordinates of the rotation center take values in the range from 0 through 1. The point with the coordinates (0,0) corresponds to the upper-left corner of the control, the point with the coordinates (1,1) corresponds to the lower-right corner of the control. The default center of rotation is (0.5, 0.5). Values outside of [0,0] and [1,1] can be clipped in some descendant classes. To set the rotation angle, use RotationAngle.

Type:

Position

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

ScrollDirections

Defines the available scroll directions.

Type:

ScrollDirections

ShowHint

Specifies whether the Hint can be shown. If ShowHint is set to True, a Hint string is displayed when the user moves the mouse over the control.

Type:

bool

Defines scrollbars visibility.

Type:

bool

ShowSizeGrip

Shows a small control in the right-bottom corner that represents the size of the changing control.

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

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

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:
