Example 1 with AddWidgetAction

use of org.csstudio.display.builder.editor.undo.AddWidgetAction in project org.csstudio.display.builder by kasemir.

the class DisplayEditor method createWidget.

/**
 * @param region Requested location and size of the new widget
 *  @param desc Description for widget to create
 */
private void createWidget(final Rectangle2D region, final WidgetDescriptor desc) {
    // Create widget of that type
    final Widget widget = desc.createWidget();

    undo.execute(new AddWidgetAction(selection, target, widget));
    // De-activate the palette, so rubberband will from now on select widgets
