Eclipse integration: ... caaaacrash when opening designer
Message 1 in thread
Hi,
I have been around since beta1 and haven't had any problems with the
eclipse-integration before but when I upgraded to the
qtjambi-linux32-gpl-4.3.0_01 release and got into some trouble.
I can't open my designer/jui-file from eclipse. I get a formidable crash.
I start eclipse and all is well, the project is ok to edit, run, debug,
..., but as soon as I open my designer/jui-file I get:
QPixmap::scaled: Pixmap is a null pixmap

It works if I open the jui-file with qtjambi/designer.sh eventhough I
get the exception:
QtJambi: Exception pending in native codeException in thread "main"

com.trolltech.tools.designer.PropertySheet.writeProperty(PropertySheet.java:345)
<repeat>
My jui-file is an old ui-file that I converted, so my first guess was
that I am an idiot and should have read the Release Notes, you know,
missed to run some conversion tool of sorts but ...
http://doc.trolltech.com/qtjambi-1.0/com/trolltech/qt/qtjambi-index.html
points to the beta so know my best guess is that nothing major happened
between last beta and final release? I'm probably just looking at the
wrong place.
What more, .... , developing on my trusted: Linux / Ubuntu Edgy +
Eclipse 3.2 + qtjambi-linux32-gpl-4.3.0_01 + java 1.5.0_05
__
My work-around is to add the designer to external tools in eclipse -
works well for me, but.
Sincerly Yours

Hi, we have found the problem that would cause the MalformedURLException. And
the fix will be included in the next release. We haven't managed to find out
what caused the VM crash that you described, but maybe it is a result of the
exception thrown earlier.
Here is a patch that you can try:
==== com/trolltech/tools/designer/CustomWidgetManager.java (text) ====
@@ -119,7 +119,7 @@
} catch (ClassNotFoundException f) {
String classPathsProperty =
System.getProperty("com.trolltech.qtjambi.internal.current.classpath");
if (classPathsProperty != null) {
- String classpaths[] =
classPathsProperty.split(System.getProperty("path.separator"));
+ String classpaths[] = classPathsProperty.split(";");
URL urls[] = new URL[classpaths.length];
for (int j=0; j<classpaths.length; ++j)
Thanks for reporting what you found :-)
Best regards
Håvard F
