A question about QTreeWidget

[henryxuv]

I am using the SetItemWidget function of QTreeWidget. I new a widget and set it to one QTreeWidgetItem, After call removeItemWidget, If I need to delete widget. what does removeItemWidget do for me.

This function make as it says ... remove widget from item. So if you did not set a widget in item, nothing have to remove. If you want to remove item from tree, just delete it.

QTreeWidget treeWidget;
QTreeWidgetItem *pOneItem = new QTreeWidgetItem;
MyOwnWidget *pCustomWidget = new MyOwnWidget;
treeWidget.SetItemWidget(pOneItem, 0, pCustomeWidget)
treeWidget.RemoveItemWidget(pOneItem,0);
treeWidget.clear()

//If I need to call those ?????If the clear and RemoveItemWidget function will release the memory automatically.
delete pCustomWidget;
delete pOneItem;

If you already call "clear":http://doc.qt.nokia.com/latest/qtreewidget.html#clear, you do not have to delete it. I'm not sure if you call "removeItemWidget":http://doc.qt.nokia.com/latest/qtreewidget.html#removeItemWidget, your pCustomWidget will be deleted.

Easy enough to test though: set a breakpoint in the destructor of MyOwnWidget, and see if it gets called.
