Style hover and selected colors for arbitrarely chosen QTreeWidgetItems

Signal a QTreeWidgetItem toggled checkbox
python,qt,pyqt,pyside,qtreewidget
The itemClicked signal is not a good choice for handling treewidget checkboxes. On the one hand, it gives false positives when not clicking on the checkbox part of an item; and on the other hand, it gives false negatives when the checkbox is toggled using the keyboard. I think the...

QTreeWidgetItem::insertChild does not its work
I found the solution: My first code was this QTreeWidgetItem* newVtxItem = new QTreeWidgetItem(parentItem); newVtxItem->setText(0, "vtx 1"); newVtxItem->setText(1, "-1"); childOfNameProfile->insertChild(0,newVtxItem); Then I correct it by deleting the parentItem of the new QTreeWidgetItem in this way: QTreeWidgetItem* newVtxItem = new QTreeWidgetItem(); newVtxItem->setText(0, "vtx 1"); newVtxItem->setText(1, "-1"); childOfNameProfile->insertChild(0,newVtxItem); The reason why the...
