XDialog

public class XSwtPage
extends org.eclipse.swt.widgets.Composite
implements XExceptionHandler, PageSupport, XAttributedComponent

A basic unit for building applications. XSwtPage integrates with page and event management facilities provided by XUI. The page also provides a number of methods to help control the page lifecycle.

Pages can be displayed using the XPageDisplay interface implemented by XApplet and invoked by the XPage manager. Pages can be constructed directly or via the XuiBuilder.

A MouseEvent.MOUSE_CLICKED is only triggered when the press and release are at the same location and this is often inadequate for end-user interaction.

Specified by:

wasMouseDoubleClicked in interface PageSupport

Returns:

true if the mouse was double clicked

wasMouseRightClicked

A utility method used to determine if the last event corrseponds to a mouse right click. The notion of a click is extended by assuming the a mouse press and release within a single component constitutes a click even if not at the same coordinate. A MouseEvent.MOUSE_CLICKED is only triggered when the press and release are at the same location and this is often inadequate for end-user interaction.

Specified by:

wasMouseRightClicked in interface PageSupport

Returns:

true if the mouse was right clicked

updateBinding

public void updateBinding(XDataBinding binding)

Update the bound model node for the binding. First the output path is reevaluated and then updated by setting the output node. Then the source path is reevaluated and set. Evaluation of the paths allows derived classes to dynamically modify the bindings. Some bindings may save the selection or state information to the output node and subsequently use it to restore the component state. This method does not alter the data held by the bound model nodes. To actually save the data use saveBoundComponentValues and to update the UI use updateBoundComponentValues.

Specified by:

Parameters:

binding - the data binding to update

updateBoundComponentValues
