[Qt-interest] 答复: QLineEdit press enter key

[pengliang(彭亮)]

Hi Tony

         I added the sentences: 

if (ui.treewidget->viewport() != NULL)
      ui.treewidget->viewport()->update();

 

But problem still exist.

 

 

 

Thanks

Ken

Hi Ken, 

 

Your subject has nothing to do with your question!  Try 'QTreeWidget does not update after being cleared'.  

 

We have this problem with all of the item view widgets on Mac OSX 10.5 with Qt 4.6.0.  I think the problem is the underlying QScrollArea.  

 

Our current workaround is to add: 

 

if (ui.treewidget->viewport() != NULL)
      ui.treewidget->viewport()->update();

after the list/table/tree is updated. 

 

Hope that helps,

 

Tony
