I have a RootPanel and a SplitLayoutPanel, I found when I add the SplitLayoutPanel inside RootPanel, the SplitLayoutPanel size is not auto fill all space of RootPanel,
but need call setSize and there is no corresponding RootPanel.getSize(), so I need try and error to set the parameter of SplitLayoutPanel.setsize to make it fill all the space of RootPanel.
is this a must to call setSize to make the ineer SplitLayoutPanel fill all the space of RootPanel?
My previous laptop never exploded like that. Read this tiny ad while I sweep up the shards.
