I actually need a composite panel "TournamentField" that consists of two
widgets, a label and a button at the right of the label. I want that the
label always consumes most available horizontal space, while the button has
a fixed size.
[ label with variable width][button]
Below is the code.
(The HorizontalLayoutPanel is just a FlowPanel which sets "float:left;" on
its children, as supposed by the article "Moving to standards mode" in the
GWT docs.
As you can see, I even needed to use a hard coded size for the height of
the label, because I do not know the default height...
This TournamentField is added to a LayoutPanel.

Size sp = gui.getSize(pnl); // size contains two ints: x and y
btn_Select.setWidth(XS_BTN + "px");
int lxs = sp.x - XS_BTN - 15;
if (lxs < 0)
lxs = 0;
lbl_Tournament.setWidth(lxs + "px");
lbl_Tournament.setHeight(sp.y + "px");
}
}
