Jeff Marin and Cay Horstmann,
Thanks to both of you for helping me out with the GridBagLayou/Canvas =
problem. Both of your suggestions helped me out to get that image on =
the Grid. Here's what I added that caused a miracle to happen:
Added the following methods:
public Dimension minimumSize()=20
{
w =3D image.getWidth(this);
h =3D image.getHeight(this);
return new Dimension(w,h);
}
public Dimension preferredSize()=20
{
return minimumSize();
}
Also added the following to my constructor:
resize(this.preferredSize());
How interesting.
I'm still not sure I understand why I need to do this - but hey it =
works.
Thanks again
Groshe

And when you do that, be sure to specify a resize() in the=20
Canvas constructor. Otherwise, the size will be assumed zero and the GBL =
will lay out your zero size canvas with great enthusiasm.

>>Is it possible to use a GridBagLayout to draw Images?
>>When I draw an image I need to specify the coordinates, but the =
GridBagLayout=20
doesn't allow that - you just add it..
>>How can I get an Image on the GridBagLayout?
I would recommend creating a subclass of Canvas (ImageCanvas
or something) which knows how to render the image on the
canvas, and then just add the canvas to your GridBagLayout.
