class Button
package feathers.controls
extends BasicButton › FeathersControl › MeasureSprite › ValidatingSprite
implements IFocusObject, ITextControl
A push button control that may be triggered when pressed and released.
The following example creates a button, gives it a label and listens for when the button is triggered:
var button = new Button();
button.text = "Click Me";
button.addEventListener(TriggerEvent.TRIGGER, (event) -> {
trace("button triggered!");
});
this.addChild(button);1.0.0

Constructor
Variables
disabledTextFormat:AbstractTextFormat
The font styles used to render the button's text when the button is disabled.
In the following example, the button's disabled text formatting is customized:
button.enabled = false;
button.disabledTextFormat = new TextFormat("Helvetica", 20, 0xee0000);1.0.0
.See also:
embedFonts:Bool
Determines if an embedded font is used or not.
In the following example, the button uses embedded fonts:
button.embedFonts = true;1.0.0
.See also:
gap:Float
The space, measured in pixels, between the button's icon and its text.
Applies to either horizontal or vertical spacing, depending on the value
of iconPosition.
If the gap is set to Math.POSITIVE_INFINITY, the icon and the text
will be positioned as far apart as possible. In other words, they will
be positioned at the edges of the button (adjusted for padding).
The following example creates a gap of 20 pixels between the icon and the text:
button.text = "Click Me";
button.icon = new Bitmap(bitmapData);
button.gap = 20.0;1.0.0
.See also:
horizontalAlign:HorizontalAlign
How the content is positioned horizontally (along the x-axis) within the button.
The following example aligns the button's content to the left:
button.verticalAlign = LEFT;Note: The HorizontalAlign.JUSTIFY constant is not supported by this
component.
See also:
icon:DisplayObject
The display object to use as the button's icon.
To render a different icon depending on the button's current state,
pass additional icons to setIconForState().
The following example gives the button an icon:
button.icon = new Bitmap(bitmapData);To change the position of the icon relative to the button's text, see
iconPosition and gap.
button.icon = new Bitmap(bitmapData);
button.iconPosition = RIGHT;
button.gap = 20.0;1.0.0
.See also:
iconOffsetX:Float
Offsets the x position of the icon by a certain number of pixels. This does not affect the measurement of the button. The button's width will not get smaller or larger when the icon is offset from its default x position.
The following example offsets the x position of the button's icon by 20 pixels:
button.iconOffsetX = 20.0;1.0.0
.See also:
iconOffsetY:Float
Offsets the y position of the icon by a certain number of pixels. This does not affect the measurement of the button. The button's height will not get smaller or larger when the icon is offset from its default y position.
The following example offsets the y position of the button's icon by 20 pixels:
button.iconOffsetY = 20.0;1.0.0
.See also:
iconPosition:RelativePosition
The location of the button's icon, relative to its text.
The following example positions the icon to the right of the text:
button.text = "Click Me";
button.icon = new Bitmap(texture);
button.iconPosition = RIGHT;1.0.0
.See also:
minGap:Float
If the value of the gap property is Math.POSITIVE_INFINITY, meaning
that the gap will fill as much space as possible and position the icon
and text on the edges of the button, the final calculated value of the
gap will not be smaller than the value of the minGap property.
The following example ensures that the gap is never smaller than 20 pixels:
button.gap = Math.POSITIVE_INFINITY;
button.minGap = 20.0;1.0.0
.See also:
paddingBottom:Float
The minimum space, in pixels, between the button's bottom edge and the button's content.
In the following example, the button's bottom padding is set to 20 pixels:
button.paddingBottom = 20.0;1.0.0
.paddingLeft:Float
The minimum space, in pixels, between the button's left edge and the button's content.
In the following example, the button's left padding is set to 20 pixels:
button.paddingLeft = 20.0;1.0.0
.paddingRight:Float
The minimum space, in pixels, between the button's right edge and the button's content.
In the following example, the button's right padding is set to 20 pixels:
button.paddingRight = 20.0;1.0.0
.paddingTop:Float
The minimum space, in pixels, between the button's top edge and the button's content.
In the following example, the button's top padding is set to 20 pixels:
button.paddingTop = 20.0;1.0.0
.text:String
The text displayed by the button.
The following example sets the button's text:
button.text = "Click Me";1.0.0
.See also:
textFormat:AbstractTextFormat
The font styles used to render the button's text.
In the following example, the button's text formatting is customized:
button.textFormat = new TextFormat("Helvetica", 20, 0xcc0000);1.0.0
.See also:
textOffsetX:Float
Offsets the x position of the text by a certain number of pixels. This does not affect the measurement of the button. The button's width will not get smaller or larger when the text is offset from its default x position. Nor does it change the size of the text, so the text may appear outside of the button's bounds if the offset is large enough.
The following example offsets the x position of the button's text by 20 pixels:
button.textOffsetX = 20.0;1.0.0
.See also:
textOffsetY:Float
Offsets the y position of the text by a certain number of pixels. This does not affect the measurement of the button. The button's height will not get smaller or larger when the text is offset from its default y position. Nor does it change the size of the text, so the text may appear outside of the button's bounds if the offset is large enough.
The following example offsets the y position of the button's text by 20 pixels:
button.textOffsetY = 20.0;1.0.0
.See also:
verticalAlign:VerticalAlign
How the content is positioned vertically (along the y-axis) within the button.
The following example aligns the button's content to the top:
button.verticalAlign = TOP;Note: The VerticalAlign.JUSTIFY constant is not supported by this
component.
