Something is stopping your program from running. Since you dont show anything else about your code it is hard to say...
If you have a problem, CUT and PASTE your code. Do not retype or simplify it. Give a COMPLETE and COMPILABLE example of your problem. Otherwise we are all guessing the problem from a fabrication where relevant details are often missing.

the problem is that its a lot of code interact with other code and etc etc etc....
i think it will be difficult for you to understand all the code to find the problem but here is the project --> deleted

i am trying to make a music player, i created the GUI with Qt Jambi (file /src/yamp/ui/YampMainWindow.java) and i am trying to list the artists in a QTreeWidget, the last line of main() in the previous file is

Source code

 
1

window.setLibrary(artists_songs);
with this i call the the setLibrary() which will add the artists in the QTreeWidget

to get the artists a use mostly the code at /src/yamp/musiclibrary/LibraryManagement.java calling from /src/yamp/YampLibrary.java


if you have any question or anything tell me, sorry if i am not very understandable :(

edit: i commented line

Source code

 
1

MultiMap artists_songs = m.YampLibrary();
in main and

Set artists = map.keySet();
TreeSet artistsSorted = new TreeSet(artists);
in setLibrary() and i change the

window.setLibrary(artists_songs);
with

window.setLibrary(null);

i'd look for code that uses startTimer/Qtimer

i haven't written any code which use those...
maybe is under the hood of some function...

if you have any question tell me.

I appreciate it :)

i change the two last lines in main so

Source code

 
1

window.setLibrary(null);
will execute before

Source code

 
1

QApplication.exec();

Funny how a line that you didnt show us was the problem...


this is why I always try and insist on complete examples, not snippets. It's a waste of time...
