What version of the product are you using? On what operating system?


java.version=1.6.0_16
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=linux, ARCH=x86_64, WS=gtk, NL=en_US
Framework arguments:  -product org.eclipse.epp.package.jee.product
Command-line arguments:  -os linux -ws gtk -arch x86_64 -product 
org.eclipse.epp.package.jee.product

Please provide any additional information below.

With Qt it looks great! I got my vertical screen real estate back in the 
treeview! woohoo!

I have just found this project and I think it is very interesting in a sense of 
making a much more compelling experience out of Eclipse. Is there any active 
involvement in this? Maybe by third parties? Any hope to run it in 2012 against 
latest Qt?

Is there any planning for Helios support?

The implementation of GC.getXORMode() is still to be done:

    public boolean getXORMode() {
        //TODO
        SWT.error(SWT.ERROR_GRAPHIC_DISPOSED);
        //      int rop2 = 0;
        //      rop2 = OS.GetROP2(handle);
        return false; //rop2 == OS.R2_XORPEN;
    }

I got a problem mixing heavyweight with lightweight components (Draw2D) which - 
I guess - relies on this method.

Are there any plans to fix this "TODO" in the near future?

Regards,
Matthias

What steps will reproduce the problem?
1. Open a Java project
2. doubleclick a class
3.

What is the expected output? What do you see instead?

I expect he file to open in the editor. Instead it expands the class treenode 
in the treeview

I want to make one of our libraries(qt based) be available for people to use as 
a plugin in eclipse.

As a first step and a proof of concept.
I have to create a simple qtjambi based plugin for eclipse. Needless to say I 
want this qt_jambi_plugin_view to open inside of eclipse and not be a popup.

I do not have sufficient knowledge to know how to, if possible, to parent 
jambi_QWidget to eclipse mdiarea.

I very much appreciate you help.

One more quick question:
I still have problems having my qt_jambi based plugin open as a popup widget 
when used as a plugin. I am missing dependencies and having problems finding 
the place to specify them in eclipse.

When plugin is loaded I get this warning:
The extensions and extension-points from the bundle "com.trolltech.qt" are 
ignored. The bundle is not marked as singleton.

after i execute it by clicking on a tool button i get the expected result Erorr:
java.lang.NoClassDefFoundError: com/trolltech/qt/gui/QApplication
at plugin_foo.actions.MyAction.....


Here is my MANIFEST.MF any ideas.

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Plugin_foo
Bundle-SymbolicName: plugin_foo; singleton:=true
Bundle-Version: 1.0.0.qualifier
Bundle-Activator: plugin_foo.Activator
Require-Bundle: org.eclipse.ui,
 org.eclipse.core.runtime,
 com.trolltech.qtjambi;bundle-version="1.2.0",
 com.trolltech.qt;bundle-version="1.2.0"
Bundle-ActivationPolicy: lazy
Bundle-RequiredExecutionEnvironment: JavaSE-1.6 

What steps will reproduce the problem?
1. Take Galileo Release
2. start
3.

What is the expected output? What do you see instead?
Complete Welcome Screen. Instead ViewPart layouting is incorrect.
Text Editor does not allow Clipboard usage, not even typing text through 
keyboard.

What version of the product are you using? On what operating system?
Galileo, current releases in download area, Windows 7 x64, 
but: JRE, SWT/Qt, Eclipse Galileo as 32bit Releases
