Global Widgets

This section provides brief descriptions of the global widgets that Nexaweb provides for Java application UI Development.

For more detailed information on any of the widgets, see the XAL Schema documentation.

Global widgets are widgets that you can define in a defs section of a UI file so that you can then use those widgets multiple places through out the UI file. For more information on using global widgets, see the documentation on the defs section.

popup

A popup is a panel that appears in a pane in front of other components including windows and dialogs. Define a popup in the <defs> section of an application and then refer to it using the popup or tooltip attribute of another component.

Nexaweb Studio does not include popup as a standalone drag and drop widget in the Palette view.

The following example shows the syntax of a popup defined in a defs section and the use of the popup in a button:

<xal xmlns="http://openxal.org/ui/java">
  <defs>
   <popup id="myPopup">
    <verticalBoxPane backgroundColor="white">
     <label text="One"/>
     <label text="Two"/>
     <label text="Three"/>
     <label text="Four"/>
     <label text="Five"/>
    </verticalBoxPane>
   </popup>
  </defs>
  <rootPane>
   <borderPane>
    <desktopPane borderPosition="center">
     <horizontalFlowPane>
      <borderPane>
       <button text="Select" borderPosition="north" popup="#myPopup"/>
       <button text="OK" borderPosition="center"/>
       <button text="Apply" borderPosition="south" />
      </borderPane>
     </horizontalFlowPane>
    </desktopPane>
   </borderPane>
  </rootPane>
</xal>
