setId back to summary

public final void setId(String value)

Sets the id of this PopupControl. This simple string identifier is useful for finding a specific Node within the scene graph. While the id of a Node should be unique within the scene graph, this uniqueness is not enforced. This is analogous to the "id" attribute on an HTML element (CSS ID Specification).

Parameters

value:String: the id assigned to this PopupControl using the setId method or null, if no id has been assigned.

Default Value

null

setMaxHeight back to summary

public final void setMaxHeight(double value)

Property for overriding the control's computed maximum height. This should only be set if the control's internally computed maximum height doesn't meet the application's layout needs.

Defaults to the USE_COMPUTED_SIZE flag, which means that maxHeight(forWidth) will return the control's internally computed maximum height.

Setting this value to the USE_PREF_SIZE flag will cause maxHeight(forWidth) to return the control's preferred height, enabling applications to easily restrict the resizability of the control.

Parameters

value:double: the maximum height

setMaxSize back to summary

public void setMaxSize(double maxWidth, double maxHeight)

Convenience method for overriding the control's computed maximum width and height. This should only be called if the control's internally computed maximum size doesn't meet the application's layout needs.

Parameters

maxWidth:double: the override value for maximum width
maxHeight:double: the override value for maximum height

See Also

setMaxWidth, setMaxHeight

setMaxWidth back to summary

public final void setMaxWidth(double value)

Property for overriding the control's computed maximum width. This should only be set if the control's internally computed maximum width doesn't meet the application's layout needs.

Defaults to the USE_COMPUTED_SIZE flag, which means that maxWidth(forHeight) will return the control's internally computed maximum width.

Setting this value to the USE_PREF_SIZE flag will cause maxWidth(forHeight) to return the control's preferred width, enabling applications to easily restrict the resizability of the control.

Parameters

value:double: the maximum width

setMinHeight back to summary

public final void setMinHeight(double value)

Property for overriding the control's computed minimum height. This should only be set if the control's internally computed minimum height doesn't meet the application's layout needs.

Defaults to the USE_COMPUTED_SIZE flag, which means that minHeight(forWidth) will return the control's internally computed minimum height.

Setting this value to the USE_PREF_SIZE flag will cause minHeight(forWidth) to return the control's preferred height, enabling applications to easily restrict the resizability of the control.

Parameters

value:double: the minimum height

setMinSize back to summary

public void setMinSize(double minWidth, double minHeight)

Convenience method for overriding the control's computed minimum width and height. This should only be called if the control's internally computed minimum size doesn't meet the application's layout needs.

Parameters

minWidth:double: the override value for minimum width
minHeight:double: the override value for minimum height

See Also

setMinWidth, setMinHeight

setMinWidth back to summary

public final void setMinWidth(double value)

Property for overriding the control's computed minimum width. This should only be set if the control's internally computed minimum width doesn't meet the application's layout needs.

Defaults to the USE_COMPUTED_SIZE flag, which means that minWidth(forHeight) will return the control's internally computed minimum width.

Setting this value to the USE_PREF_SIZE flag will cause minWidth(forHeight) to return the control's preferred width, enabling applications to easily restrict the resizability of the control.

Parameters

value:double: the minimum width

setPrefHeight back to summary

public final void setPrefHeight(double value)

Property for overriding the control's computed preferred height. This should only be set if the control's internally computed preferred height doesn't meet the application's layout needs.

prefHeight:double: the override value for preferred height

See Also

setPrefWidth, setPrefHeight

setPrefWidth back to summary

public final void setPrefWidth(double value)

Property for overriding the control's computed preferred width. This should only be set if the control's internally computed preferred width doesn't meet the application's layout needs.

skinProperty back to summary

public final ObjectProperty<Skin<?>> skinProperty()

Implements javafx.scene.control.Skinnable.skinProperty.

Skin is responsible for rendering this PopupControl. From the perspective of the PopupControl, the Skin is a black box. It listens and responds to changes in state in a PopupControl.

There is a one-to-one relationship between a PopupControl and its Skin. Every Skin maintains a back reference to the PopupControl.

A skin may be null.

styleProperty back to summary

public final StringProperty styleProperty()

A string representation of the CSS style associated with this specific PopupControl. This is analogous to the "style" attribute of an HTML element. Note that, like the HTML style attribute, this variable contains style properties and values and not the selector portion of a style rule.

A value of null is implicitly converted to an empty String.

Returns:StringProperty: the style property
Default Value: null
