Code:

//TIP: Following code is only fabricated by looking at the docs, i have not tested it.
if(treeWidget->currentItem() && !treeWidget->currentItem()->parent()){
delete treeWidget->takeTopLevelItem(treeWidget->indexOfTopLevelItem(treeWidget->currentItem()));
}else if(treeWidget->currentItem() && treeWidget->currentItem()->parent()){
delete treeWidget->currentItem()->parent()->takeChild(treeWidget->currentItem()->parent()->indexOfChild(treeWidget->currentItem());
}

One this is done, QTreeWidget should update it accordingly.

Hope this works

:) This method do exist, I assure you:
http://doc.trolltech.com/4.1/qtreewi...ml#currentItem

PS. yogeshm02, I think here there is need to reformat the example code to more suitable kind.

Do not just try to use the code given by me. Try to understand what is being done, and then you would have no questions. ;) Refer to qt docs.

Thank your help !
now I know your code about how to delete a treewidgetitem. but now my question is
how can I get the treewidgetitem which the mouse has clicked?
I just want to realize the follow operation: click a treewidgetitem and then press a delete button to delete the clicked item.

You can sublass QTreeWidget and reinplement keyPressEvent ( QKeyEvent * )
:rolleyes:

or..try use eventFilter() for main widget
