|Subject:||[Qt-interest] The "+" disappears in QTreeView sometimes.|
|Date:||Tue, 16 Mar 2010 18:44:43 -0400|
I use QTreeView to show a tree model. The data of the model changes from time to time.
The weird thing is sometimes the "+" symbol ahead of a parent item disappears, even though
clicking on the place it should be still works.
I tried Qt4.6.0 and Qt4.6.2 on Windows and Linux and they all have such problem. Is this a Qt bug?
Any way to work around it?
