How keep a group in a tree widget collapsed
Message 1 in thread
Hello dev partners,
First I have a QTreeWidget and I have in it items as groups of other
items.
Now I don't know if setItemExpanded(the item I want to Expand/Collapse is a
group) is a native qt function, so if is, how I can make it collapse, and
how can I put in an "IF" sentence, like "if (item isexpanded)" or
collapse.
Any help will be great

Searching the docs, maybe there is something you could use...
You should have a look at
bool QTreeWidgetItem::isExpanded () const
bool QTreeWidget::isItemExpanded ( const QTreeWidgetItem * item ) const
void QTreeWidgetItem::setExpanded ( bool expand )
The first and second one returns the expanded state of the current item,
the third can set an item to be collapsed/expanded.
So the if statement could be like
if( myTreeWidget.isItemExpanded(myItem) )
myItem.setExpanded(false)
If isItemExpanded is true, then it's expanded else it's collapsed.
