I am a GWT programmer trying to get to grips with using PlayN with Tripleplays gui library.
Having a little bit of trouble working out how to get a border layout filling up all the space of its container. (presumably with the middle space expanding to fill the available size)
BorderLayout border = new BorderLayout(3);
Group mainLayout = new Group(border);
mainLayout.setConstraint(AxisLayout.stretched());
Button Center= new Button("test");
Center.setConstraint(BorderLayout.CENTER);
mainLayout.add(Top);
mainLayout.add(Bottom);
mainLayout.add(Left);
mainLayout.add(Center);
Top Bottom and Left are similarly specified to BorderLayout.Left, top etc.
the whole thing is then added to the root screen with
_root.setConstraint(AxisLayout.stretched());
_root.add(0, mainLayout);
(_root itself just has a AxisLayout.vertical() ...which I am assuming makes it act somewhat like a gwt vertical panel)
At the moment the vertical space seems to be filled, but not the horizontal.
Any ideas where I am going wrong?
I would suggest to set
border.setConstraint(AxisLayout.stretched());
before adding border to mainLayout. This will tell mainLayout to strech this child widget.
