Forgot to copy/past this "no-so-necessary" peace of working code:
Note, onLoad is used so calls to setSize will be delayed and
onResize() would have more chance to be called (I didn't check).
public class test implements EntryPoint {
private class Menu extends Composite {
public Menu() {
FlowPanel panel = new FlowPanel();
panel.add( new HTML( "menu" ) );
initWidget( panel );
}
};
private class Application extends Composite implements
RequiresResize, ProvidesResize {
private DockLayoutPanel indexPanel;
private DecoratorPanel appDecorator;
public Application() {
indexPanel = new DockLayoutPanel( Unit.PX );
indexPanel.addNorth( new HTML("north blah"), 100 );
indexPanel.addWest( new HTML("west blah"), 100 );
indexPanel.addEast( new HTML("east blah"), 100 );
indexPanel.add( new Menu() );
//indexPanel.setSize( "100%", "100%" );
//indexPanel.setSize( "100%", "300px" );
appDecorator = new DecoratorPanel();
appDecorator.setWidget( indexPanel );
appDecorator.setStylePrimaryName( "custom_decorator" );
//appDecorator.setSize( "100%", "100%" );
initWidget( appDecorator );
}
public void onResize() {
indexPanel.onResize();
}
public void onLoad()
{
indexPanel.setSize( "100%", "300px" );
appDecorator.setSize( "100%", "100%" );
}
};
public void onModuleLoad() {
RootLayoutPanel.get().add( new Application() );
}
}
