Hi all,
I am having trouble controlling my table view’s column sizes.
I thought implementing the delegate’s sizeHint was a way to do this but
it won’t work for me.
Can somebody please point out what I’m missing?
Here is my test code:
|from PySide2 import QtWidgets from PySide2 import QtCore class
MyItemDelegate(QtWidgets.QStyledItemDelegate): def __init__(self):
super(MyItemDelegate, self).__init__() def sizeHint(self, option,
index): # why is this never called? print 'hint' return
QtCore.QSize(10,10) class MyView(QtWidgets.QTableView): def
__init__(self, parent=None): super(MyView, self).__init__(parent)
self.setItemDelegate(MyItemDelegate()) class
MyModel(QtCore.QAbstractTableModel): def __init__(self, parent=None):
super(MyModel, self).__init__(parent) self.my_data = [i for i in
xrange(100)] def data(self, index, role): '''Return required data for
nodes''' if role == QtCore.Qt.DisplayRole: return 'item
{}'.format(self.my_data[index.row()]) def columnCount(self, index=None):
return 2 def rowCount(self, index=None): return len(self.my_data) class
MyPanel(QtWidgets.QWidget): def __init__(self, parent=None):
super(MyPanel, self).__init__(parent) self.init_UI() def init_UI(self):
# widgets self.itemView = MyView() self.model = MyModel()
self.itemView.setModel(self.model) layout = QtWidgets.QVBoxLayout()
layout.addWidget(self.itemView) self.setLayout(layout) if __name__ ==
'__main__': import sys app = QtWidgets.QApplication([]) w = MyPanel()
w.show() sys.exit(app.exec_()) |
Thanks,
frank
