Hi all :

first of all ... sorry for the noob question !!!

Is there a way to put an background image in the Jtoolbar and JToolmenu?

I am new in java but old (jurassic old) in VB and VFP.
There, in the activeX, sometimes I can chose a background image for the
toolbars.

thanks

You will have to subclass JToolbar and in the paintComponent() method,
display the image.

Something like:

Image myImage = [load image from somewhere];

public void paintComponent (Graphics g)
{
g.drawImage(myImage, 0, 0, this);
}

Not sure what you mean by JToolmenu. Do you mean JMenu or JMenuBar? If so,
you can try the same technique with them.

do you mean like this ?
It just puts a black stripe in 0,0 and the JMenuBar under it :-(

what am I doing wrong ?

*******************************************
import javax.swing.* ;
import java.awt.* ;

public class MyToolbar extends JMenuBar {

Image myImage2 ;

public MyToolbar() {

ImageIcon("/home/pedro/JavaApplication1/FundoMenu2.bmp") ;
Image myImage2 =
Toolkit.getDefaultToolkit().getImage("/home/pedro/JavaApplication1/FundoMenu2.jpg")
;
}

public void paintComponent (Graphics g)
{
if(myImage2!= null)
{
g.drawImage(myImage2, 0, 0, this);
}
}

}

I suspect the problem is that the image isn't fully loaded. In Java, you
have to go through the extra step of waiting for the image to fully load
using the MediaTracker (a poor design decision IMO). Something like:

// The this argument is the component that will use the image
MediaTracker mt = new MediaTracker(this);
try
{
mt.addImage(image, 0);
mt.waitForID(0);
}
catch (InterruptedException e)
{
}

Now you can use the image for drawing.

Of course, it is also possible that you can't draw a background image for
JMenuBar. I have only done it for JPanels.
