public class JXGlassBox
extends JXPanel

Component used to display transluscent user-interface content. This component and all of its content will be displayed with the specified "alpha" transluscency property value. When this component is made visible, it's content will fade in until the alpha transluscency level is reached.

If the glassbox's "dismissOnClick" property is true (the default) then the glassbox will be made invisible when the user clicks on it.

This component is particularly useful for displaying transient messages on the glasspane.

Constructor Detail

JXGlassBox

public JXGlassBox()

JXGlassBox

public JXGlassBox(float alpha)

Method Detail

setAlpha

public void setAlpha(float alpha)

Description copied from class: JXPanel

Set the alpha transparency level for this component. This automatically causes a repaint of the component.

TODO add support for animated changes in translucency

Overrides:

setAlpha in class JXPanel

Parameters:

alpha - must be a value between 0 and 1 inclusive.

dismiss

public void dismiss()

Dismisses this glass box. This causes the glass box to be removed from it's parent and ensure that the display is correctly updated.

isDismissOnClick

public boolean isDismissOnClick()

Determines if the glass box if dismissed when a user clicks on it.

Returns:

true if the glass box can be dismissed with a click; false otherwise

See Also:

Configures the glass box to dismiss (or not) when clicked.

Parameters:

dismissOnClick - true if the glass box should dismiss when clicked; false otherwise

See Also:
