Example 6 with UndoableActionManager

use of org.csstudio.display.builder.util.undo.UndoableActionManager in project org.csstudio.display.builder by kasemir.

the class CreateGroupAction method run.

@Override
public void run() {
    editor.getWidgetSelectionHandler().clear();

    final GroupWidget group = new GroupWidget();
    // Get bounds of widgets relative to their container,
    // which might be a group within the display
    // or the display itself
    final Rectangle2D rect = GeometryTools.getBounds(widgets);
    // Inset depends on representation and changes with group style and font.
    // Can be obtained via group.runtimePropInsets() _after_ the group has
    // been represented. For this reason Style.NONE is used, where the inset
    // is always 0. An alternative could be Style.LINE, with an inset of 1.
    final int inset = 0;
    group.propStyle().setValue(Style.NONE);
    group.propTransparent().setValue(true);
    group.propX().setValue((int) rect.getMinX() - inset);
