Hi,

Did anyone manage to create tree widgets on a pocket pc ? I've tried
different builds of SWT (P.Profile) but I always end up with the same
error :

java.lang.IllegalAccessError:
org/eclipse/swt/widgets/Widget.checkBits(IIIIIII)I

whenever I try to declare a tree, even with simple stuff such as :

Tree testTree = new Tree(this, SWT.SINGLE);

Any ideas are welcomed !
Thanks,

Guillaume Godet-Bar

You need to use the SWT build from the Eclipse download page. The ones
shipping with WSDD may not contain widgets or API not required for embedded
profiles.

e.g.
http://fullmoon.ottawa.ibm.com/downloads/drops/I20041216-080 0/index.php

Look for "SWT Binary and Source"
And pick up the "Windows CE (ARM Pocket PC)" build.
Don't confuse it with the J2ME version that runs over CLDC.

Hope it helps,
Chris

Hi Chris,
Well I've reinstalled a clean j9, tried several SWT builds (for Pocket
PC, no J2ME, etc.) from the Eclipse project, but I still have the same
error. I've also tried some really stripped down code (imports omitted) :

public class TreeTest {

public static void main(String[] args) {
Display display = new Display();
Shell shell = new Shell(display, SWT.CLOSE);

GridLayout grid = new GridLayout();
grid.numColumns = 1 ;
shell.setLayout(grid);

Tree arbre = new Tree(shell, SWT.SINGLE);

shell.open();

while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}
}

.... but once again I get the error. I've looked in the SWT sources, but
this bug really doesn't make sense (error while checking a standard tree
style ?).

Looking for some insight...

Guillaume

I used a -Xbootclasspath/p:/share/java/SWT.jar equivalent in my link.
And it worked. That saves the day...
