Common Navigator: icon & text overlap, no icon for subtree [message #1745085]

I am quite new to the eclipse RCP platform.
I am using Neon, and the RCP project is e4 based on the compatibility layer.

I have successfully added several components to my perspective (console, properties, problems, tasks, custom editor...) and I am now trying to improve the workspace tree.

This tree is based on the Common Navigator, and I followed in details the tutorial in the help section, as well as read a lot of documentation on the internet. My tree is functionnal, but with some caveats; I've been unsuccessfully searching for solutions.

1) Icon and Label overlap for most entries
2) I have no sign (+ or >) to show items that have subtrees; this is particularly annoying for entries that can both be edited and own a subtree.
3) I have no icon at the project level

index.php/fa/27301/0/

Any help is welcome.

That's pretty baffling. I'm going to guess: some variant of Linux with an older GTK3? Earlier builds of GTK3 are notoriously buggy. If so, try running with SWT_GTK3=0 in your environment to force SWT to use GTK2.

Hum, wrong guess....

Windows 10. I forgot to mention it.

Check your logs -- it sounds like you have an exception being thrown somewhere that's throwing off SWT. You could also add exception breakpoints on SWTError and SWTException, just in case they're somehow being suppressed.

Done this: logs are mostly empty, no exception caught in the debugger (caught or uncaught)...

Would you have any other idea ?

I send you my current project.

Just copied from examples on the internet... nothing fancy: I'm just trying to lay down the framework which I believe I'll need later, replacing the examples code with my own.

I also noticed that the Perpective.java code was not invoked, Probably a problem due to my bad understanding of 3x over e4.
