Re: TGMainFrame / TGListBox / TGComboBox refresh

Hi Ilka,

ok, that was not so easy - the project has few dozen packages and lots of inter- and external dependencies.

I have a very small, masively commented out and modified extract, in
http://hepunx.rl.ac.uk/~candreop/outbox/for_ilka/

You need to

% mv example.tar.gz <your-work-dir>
% cd <your-work-dir>
% tar xzvf example.tar.gz
% cd example/lib
% make <-- produces libVldGui.so
% cd ../test/
% make <-- produces nuvld_gui executable
% ./nuvld_gui &

Before the last step add <your-work-dir>/example/lib to the LD_LIBRARY_PATH

I hope that the Makefiles will work for you and there is no residual dependency on all the stuff that is not included here.

Running the nuvld_gui, you should see that the listboxes titled 'cross section', 'initial state' behave correctly when you press the 'select all' check-button. (they use gClient->NeedRedraw(mylistbox->GetContainer());)

The 'experiment' list-box behaves in a flaky way and makes all listbox entries to momentarily dissaper. (It uses TGMainFrame's Layout() )

Brett,

thanks - I was just looking for something like this.

cheers,
