HACK

The first section draws the gray lines at the top. Midway through, y is reset

based on the panel height, and then the bottom lines are drawn.

Add the Corner Icon

Next, you need to add the resize icon—preferably made to resemble real

Windows resize icons

[Hack #36]. Make a JLabel for the corner icon and add

the icon to it. Since this hack is mimicking the Explorer status bar, use the

TriangleSquareWindowsCornerIcon. Also, remember to set the label opacity to

false. This makes the status panel background show through the icon:

JLabel resizeIconLabel = new JLabel(new TriangleSquareWindowsCornerIcon( ));

resizeIconLabel.setOpaque(false);

Now, you need to add the label to the panel. You need the resize icon to be

at the right, on the bottom of the bar. For this to work, set the

JStatusBar

layout to a BorderLayout. Then create another panel called rightPanel and

set its

layout to BorderLayout as well. Add the rightPanel to the status bar,

to the east; add the resize icon to the

rightPanel, to the south. Don’t forget

to set the

rightPanel’s opacity to false as well. This will place the icon on

the bottom right of the status bar:

JPanel rightPanel = new JPanel(new BorderLayout( ));

rightPanel.setOpaque(false);

rightPanel.add(resizeIconLabel, BorderLayout.SOUTH);

add(rightPanel, BorderLayout.EAST);
