• create a class which extends from ULCToolBar (e.g. MyToolBar)
• add some buttons in it, save.

• Create a class which extends from ULCFrame
• create a border layout pane
• add the MyToolBar to the borderlayout pane

• add the borderlayoutpane to the frame.
  --> the MyToolBar is not shown correctly on the canvas. During runtime everything is fine.

Reason: When no preferred size is set in ULC, there is no way to find out the preferred size computed of the layout manager in Swing. Therefore we just assume a "default" preferred size (20,20) during design time.

Workaround:

• set the preferred size to something meaningful in the frame class and wrap it in:

if (Beans.isDesignTime() {
toolbar.setPreferredSize(new Dimension(100, 50);
}
