QTableView: openPersistentEditor doesn't resize

beatreichenbach

Hello,
I'm finding that editors opened with openPersistentEditors do not resize until the resize action has stopped.

Here's my code:

from PySide2 import QtCore, QtGui, QtWidgets

class Delegate(QtWidgets.QStyledItemDelegate):
    def createEditor(self, parent, option, index):
        editor = QtWidgets.QComboBox(parent)
        editor.addItems(map(str, range(5)))

        return editor

class Main(QtWidgets.QMainWindow):
    def __init__(self, parent=None):
        super().__init__(parent)

        self.tableview = QtWidgets.QTableView()
        self.model = QtGui.QStandardItemModel()
        self.tableview.setModel(self.model)
        self.setLayout(QtWidgets.QVBoxLayout())
        self.layout().addWidget(self.tableview)

        items = []
        for i in range(5):
            item = QtGui.QStandardItem()
            items.append(item)

        self.model.appendRow(items)
        self.tableview.setItemDelegateForColumn(1, Delegate(self))

        self.tableview.openPersistentEditor(self.model.index(0, 1))

if __name__ == '__main__':
    import sys
    app = QtWidgets.QApplication(sys.argv)
    main = Main()
    main.show()
    sys.exit(app.exec_())

And here's a screenshot of what the combobox looks like when resizing the columns.

I kept the example code as simple as possible, is there anything I'm missing?

Thanks,
Beat

@beatreichenbach I do not reproduce the problem, try adding app.setStyle("fusion")

That didn't fix the issue itself. I appended another gif of the issue. This happens both in "standalone" Qt and in a dcc such as maya.

@beatreichenbach okay, that's not the error you were describing. Now with the .gif the error is better understood.

what is your PySide2 version?

I'm using the latest PySide2 package available through pip: https://pypi.org/project/PySide2 which is currently PySide2 5.15.2.
