QTreeView update

Message 1 in thread

I have a QTreeView whit a model.
At run time, when the widget that shows the QTreeView is opened i change 
the model of QTreeView.
How can I update the widget and the QTreeView?
I try with lpTreeView->updateGeometry(); but it doesn't run.

Thanks
Teo

Hi,

I did it another way:
   - setup a model for my view on initialization
   - at run-time change some data structure behind Qt-model, not the model
     itself and call reset() on model

HTH,
Albert

Have a look here:

nd-removing-rows 

Once you have a "correct" model, the view should automagically react to
changes.

Cheers,
Peter

Is there some way to use wildcards in a .pro file?

For example:

   SOURCES += ..\cpp\*.cpp

This was possible in Qt 3 -- not sure if there's another way in Qt 4.

Have you tried using slashes (Qt way) instead of backslashes (Window's way)?

    SOURCES += ../cpp/*.cpp

I *thought* I had... :-)

This works:

   SOURCES += ..\cpp\*.cpp

Thanks (and to André)
