0 top margin on JPanel
Is there any way to add 0 margin/padding to a JPanel so it fits the WHOLE screen it's suppose?
Here is what I am talking about: (see the little space above the panel? why doesn't it cover that as well?)
Here is the way it's setup:
labelStatus = new JLabel("\n\nSorry, the server crashed!");
labelStatus.setForeground(Color.WHITE.brighter());
statusPanel = new JPanel();
statusPanel.setBackground(Color.RED.darker());
statusPanel.add(labelStatus);
statusPanel.setPreferredSize(new Dimension(513,352));
and this开发者_如何学C is how it gets iniated:
} catch (Exception rwe) {
// System.exit(0);
game.add(statusPanel);
game.remove(yPanel);
game.remove(xPanel);
game.remove(roomPanel);
game.remove(userPanel);
game.remove(titlePanel);
game.remove(introPanel);
statusPanel.setOpaque(true);
labelStatus.setVisible(true);
System.out.println("Server went down -- crap!");
c.append("\nServer crashed!");
rwe.printStackTrace();
}
So.. how do I fix that small gap?
By default, all containers use the layout manager FlowLayout
. FlowLayout specifies an hgap and a vgap to separate components. Try this:
((FlowLayout)game.getLayout()).setVgap(0);
It's strange, though, that there's no horizontal gap on the left.
