I am looking to have per-pixel translucency support, but I'm uncertain as to which software I have to replace or change. The desktop environment (nonexistent I suppose), the WM, the compositor?
This is on bionicpup64, 8.0 with the standard graphical desktop.
I have already tried xfce which didn't work.
The code below checks whether per-pixel translucency is supported or not.
Code: Select all

super ("Per-Pixel Translucency Demo");
JPanel gradPanel = new JPanel ()
{
// Transparent red
Color colorA = new Color (255, 0, 0, 0);
// Solid red

protected void paintComponent (Graphics g)
{
Graphics2D g2d = (Graphics2D) g;
GradientPaint gp;
gp = new GradientPaint (0.0f, 0.0f, colorA,
0.0f, getHeight (),
colorB, true);
g2d.setPaint (gp);
g2d.fillRect (0, 0, getWidth (),
getHeight ());
}
};
gradPanel.setPreferredSize (new Dimension (300, 200));
gradPanel.setLayout (new BoxLayout (gradPanel, BoxLayout.Y_AXIS));
JButton btnClose = new JButton ("Close");

al = new ActionListener ()
{

{

btnClose.addActionListener (al);
btnClose.setAlignmentX (0.5f);
gradPanel.add (Box.createVerticalGlue ());
gradPanel.add (btnClose);
gradPanel.add (Box.createVerticalGlue ());
setContentPane (gradPanel);
if (!getGraphicsConfiguration ().isTranslucencyCapable ())
{
System.err.println ("per-pixel translucency not in effect for "+
"this graphics configuration");
System.exit (0);
}
setBackground (new Color (0, 0, 0, 0)); // Achieve per-pixel
// translucency.
pack ();
setLocationRelativeTo (null);
setVisible (true);
}
public static void main (String [] args)

r = new Runnable ()

public void run ()

if (!ge.getDefaultScreenDevice ().
isWindowTranslucencySupported

{
System.err.println ("per-pixel translucency isn't "+
"supported");
return;
}
new PPTDemo ();
}

EventQueue.invokeLater (r);
}
}
Note: I did make a post on this and later deleted, but realized there wasn't anywhere else where this would fit.. so yeah.
