IllegalArgumentExceptions in VE [message #82326]

Hi.

I have a toolbar with some buttons. But when I add an icon to a
toolbar-button
(
URL url = getClass().getResource("img/ball_green_off.gif");
jButton1.setIcon(new ImageIcon(url));
)
, the warning-icon appears on the button with the following text:
icon : java.lang.IllegalArgumentException (IWAV0177E Expression "url" is
too complicated. - new ImageIcon(url))

The url-path is quite short and the icon can be found. I added the same
icon to a menuItem, without getting such a warning.

Could this be a bug in the VE?

Another IllegalArgumentException appears in a scrollpane with contains a
tree. When I put the standard tree control from the palette into the
scrollpane (generated code is: jScrollPane.setViewportView(getJTree());),
the tree is shown without exception. but when I create my own tree and
change the default code in the getJTree-Method
(jTree = new JTree();) to the following
(
DefaultMutableTreeNode top =
new DefaultMutableTreeNode("Root Node");
jTree = new JTree(top);
),
the tree cannot be painted in the ve anymore and a warning with an
illegalArgumentException occurs with the following text:
viewportView : java.lang.IllegalArgumentException (IWAV0167E Currently
methods need receiver (getJTree))

Can you explain this?

Many thanks,
Rebecca

What version are you using (I think this will work as of 1.0.2) if you
add this to the URL url line:

> URL url = getClass().getResource("img/ball_green_off.gif"); // @jve

But this may not work either because it is a separate variable and to us
it doesn't look like a "new" instance (i.e. new SomeClass()). If
you had done jButton1.setIcon(new ImageIcon(getClass()....) instead, I
think that will work because we put special code in for the ImageIcon
constructor to handle this.

This is more complicated than we currently can handle. Again try putting
// @jve on the DefaultMutableTreeNode top = line so that we know top
is something of importance.

Hi Rich.

Thanks for your help. The //@jve-command doesn't work in version 1.0.2,
I'm afraid. But I've written the url-term directly into the parameters of
the ImageIcon-constructor. Then the designer can resolve it. The same I
did with the tree-constructor (jTree = new JTree(new
DefaultMutableTreeNode("Root"));). With the help of the method
tree.getModel().getRootNode() you can access the rootNode in the
createNodes-method with is then called later.

I don't know if that can be useful, but I've encountered error IWAV0167E and the solution was deleting the comment on the last code line; in my case, the line was

} // @jve:decl-index=0:visual-constraint="14,18"

I've found the solution simply creating a new Swing JFrame and analyzing the differences.

Ciao
