Hi all,
For some reason the paintComponent is never called to print the
image. The image is valid, i have tested it with setIconImage(image)
and it worked fine. Why is the paintComponent never called? Any help
would be appreciated. Thanks in Advance.
The ProgressFrame is called from a run method, which is in a class
that implements Runnable. Which is called by creating a new thread.
Here is the code for the ProgressFrame:
<snip>
Works for me--draws the image (when main added.) Are you sure busy.jpg is=
in
the correct location or that Resources is capitalized correctly? It is=
best
also to launch the window from the EDT as in:
SwingUtilities.invokeLater (new Runnable () {
public void run () {
ProgressFrame pf = new ProgressFrame ();
}
});

That does work. But I forgot to mention that I am calling the method
from actionPerformed(ActionEvent ae).
A main frame has menu items that correspond to actions. When one of
them is executed it checks if ae.getSource equals to the menu item.
E.g.
JMenuItem source = (JMenuItem) ae.getSource();
if (source == open) {
openFile();
}
else if (...
When openFile is called, which creates the new thread... it does not
show the image.
But if an argument is passed to the main method, it calls openFile
(fileName) it does show the image.
openFile() and openFile(File f) have the similar code.
does anyone have any ideas why there is a difference?
Thanks in advance
