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
- AfterConstruction()¶
Responds after the last constructor has executed and loads the control presentation. FMX.StdCtrls.TPresentedTextControl.AfterConstruction inherits from FMX.Controls.Presentation.TPresentedControl.AfterConstruction. All content below this line refers to FMX.Controls.Presentation.TPresentedControl.AfterConstruction. Responds after the last constructor has executed and loads the control presentation. AfterConstruction is called automatically after the object’s last constructor has executed. Do not call it explicitly in your applications.
- ApplyStyleLookup()¶
Gets and applies the style of a TStyledControl.
- ApplyTriggerEffect(AInstance: FmxObject, ATrigger: str) None¶
Applies the specified mouse trigger effect to all the children of this FMX object that are of type TEffect. ApplyTriggerEffect iterates through all the children of this FMX object and, if one of them is of type TEffect, applies the mouse trigger given through the ATrigger parameter (which can be ‘IsMouseOver’, ‘IsMouseOver’, ‘IsDragOver’, and so on). AInstance specifies the instance of the FMX object to which the trigger effect is applied.
- AutoTranslate¶
Specifies whether the control’s text should be translated
- BeforeDestruction()¶
Performs any necessary actions before the first destructor is called. FMX.Controls.TStyledControl.BeforeDestruction inherits from System.Classes.TComponent.BeforeDestruction. All content below this line refers to System.Classes.TComponent.BeforeDestruction. Performs any necessary actions before the first destructor is called. BeforeDestruction is called automatically immediately before the component’s first destructor executes. Do not call it explicitly in your applications. As implemented in TComponent, BeforeDestruction checks whether the Destroying method has been called, and if not, calls it. Descendants that override this method to perform other actions before a component is destroyed should call the inherited method first to ensure that this check takes place.
- Change()¶
Calls DoChanged when any of the styled text representation properties of the control changes.
- ControlType¶
ControlType:
- DefaultStyleLookupName¶
Returns a string with the name of the default style of this control
- DefaultTextSettings¶
Stores a TTextSettings type object that keeps the default values of the text representation properties. DefaultTextSettings is set during the loading of the style in the ApplyStyle method.
- Type:
TextSettings
- FindStyleResource(AStyleLookup: str, AClone: bool) FmxObject¶
Finds the linked resource object for the style specified by name. The AStyleLookup parameter specifies the name of the style. If AStyleLookup is empty, FindStyleResource returns nil. If no resource object is linked directly to the control, FindStyleResource looks to the styles of the control’s children. If no resource object is found, it returns nil. Clone determines whether the returned style resource object should be the original style object (False) or a copy of the original (True). Finds the linked resource object for the style specified by name. The AStyleLookup parameter specifies the name of the style. If AStyleLookup is empty, FindStyleResource returns nil. If no resource object is linked directly to the control, FindStyleResource looks to the styles of the control’s children. If no resource object is found, it returns nil. Clone determines whether the returned style resource object should be the original style object (False) or a copy of the original (True).
- Font¶
Specifies the font to use when displaying the text.
- Type:
Font
- FontColor¶
Specifies the font color to use when displaying the text. This property sets or returns a value of the TAlphaColor type.

int
- HasPresentationProxy() Boolean¶
- Inflate()¶
Call this procedure to get and apply its style lookup.
- LoadPresentation()¶
- Model¶
DataModel:
- NeedStyleLookup()¶
Call this procedure to indicate that this control requires to get and apply its style lookup.
- PointInObjectLocal(X: float, Y: float) bool¶
Checks whether the point specified by local coordinates belongs to the control area. PointInObjectLocal returns True if the specified point belongs to the control area, and False otherwise. The X and Y are the local coordinates of the point to be checked (compare with PointInObject):
X is the X coordinate. Y is the Y coordinate. The local coordinates of the upper-left corner of the control rectangle are (0,0), and the local coordinates of the lower-right corner are (Width, Height). The points of the control boundary specified by BoundsRect belong to the control and PointInObjectLocal returns True for them. If a control supports the Touch property, the control area can be optionally inflated on the values specified by the TouchTargetExpansion property. TouchTargetExpansion keeps four optional parameters representing the expansion for the four sides of the control in pixels (Bottom, Left, Right, and Top). The dclasses can change the ‘control area’ definition. For example:
The FMX.Objects.TSelection class extends the ‘control area’ definition relative to BoundsRect. FMX.Objects.TSelection.PointInObjectLocal also returns True if the point belongs to any of small rectangles of the four grip controls used to manage the selection shape. The rectangles of the grip controls are rectangles surrounding the four corners of the TSelection rectangle. The Width and Height of these rectangles are equal to 2 * GripSize. For example, the grip control’s rectangle of the upper-right corner UR_Corner of TSelection is defined by the following corners: (UR_Corner.Top - GripSize, UR_Corner.Right - GripSize)–upper-left corner of the grip. (UR_Corner.Top + GripSize, UR_Corner.Right + GripSize)–lower-right corner of the grip. FMX.Objects.TSelectionPoint.PointInObjectLocal returns True if the specified point belongs to the rectangle of the grip control corresponding to the TSelectionPoint object, and False otherwise.
- PrefixStyle¶
Determines whether the ampersand character (&) is considered as a special prefix character. The default value is TPrefixStyle.HidePrefix, which means that the (first) ampersand is hidden at run-time.
- Type:
PrefixStyle
- Presentation¶

- PresentationProxy¶
PresentationProxy:
- PresentationState¶
PresentationState:
- RecalcEnabled()¶
Forces the current control to recalculate its enabled state. RecalcEnabled also forces the control’s children to recalculate their enabled state.
- RecalcOpacity()¶
Forces the current control to recalculate its Opacity property. RecalcOpacity also forces the control’s children to recalculate their Opacity property.
- ReloadPresentation()¶
- ResultingTextSettings¶
Keeps final values of text representation properties. These values are really used to draw texts in a control. ResultingTextSettings keeps a TTextSettings object that manages the final values of the text representation properties. These values are really used to draw texts in a control. To obtain values stored in ResultingTextSettings, a control uses the StyledSettings property. For example, if StyledSettings contains the TStyledSetting.Family value, then the TFont.Family value is taken from the DefaultTextSettings. (That is the font family name defined in the loaded style is used. The font family name defined by the programmer in the Object Editor is ignored.) Oppositely, if StyledSettings does not contain TStyledSetting.Family, then the font family name defined by the programmer in the Object Editor is used and the font family name defined in the loaded style is ignored. 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. RecalculateTextSettings updates the ResultingTextSettings.

TextSettings
- StartTriggerAnimation(AInstance: FmxObject, ATrigger: str) None¶
Embarcadero Technologies does not currently have any additional information.
- StartTriggerAnimationWait(AInstance: FmxObject, ATrigger: str) None¶
Embarcadero Technologies does not currently have any additional information.
- 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
- Text¶
Specifies the text that will be displayed over the surface of this control. 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.
- Type:
str
- TextAlign¶
Specifies the horizontal alignment of the text in this control. This property can take values of the TTextAlign enumeration.
- 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
- ToString()¶
Returns a string containing the class name. FMX.StdCtrls.TPresentedTextControl.ToString inherits from System.TObject.ToString. All content below this line refers to System.TObject.ToString. Returns a string containing the class name. By default, the ToString returns a string containing the class name of the instance that is being called. For example, calling ToString on a TButton instance returns a string containing “TButton”.
Note: ToString is intended to be overridden in user-derived classes, to provide consumer objects with a string representation.
- Trimming¶
Specifies how the text is trimmed when it exceeds the edges of the text area in this control. This property sets or returns a value of the TTextTrimming type.
- Type:
TextTrimming
- UnloadPresentation()¶
- VertTextAlign¶
Specifies the vertical alignment of the text in this control. This property can take values of the TTextAlign enumeration.
- Type:
TextAlign
- WordWrap¶
Specifies whether to wrap the text inside the control when the text length exceeds the text area width.
- Type:
bool
