问题 I have made multi-select QComboBox . Items are checkable (every item have check box and text value). CheckBox is checked only when user click on it.

This is how I set model to combo box: areas = ["Area one", "Area two", "Area three", "Area four"] model = QtGui.QStandardItemModel(5, 1)# 5 rows, 1 col firstItem = QtGui.QStandardItem("---- Select area(s) ----") firstItem

问题 i am programming a custom component which extends a JComboBox. My problem is, the PopupMenu won't actualise its size if i am adding or removing an item. So there are e.g. 2 items in the list, but if there were 4 before i had 2 "empty" items in the PopupMenu as well. The only workaround i found was to do (in JIntelligentComboBox.java line 213) this.setPopupVisible(false); this.setPopupVisible(true); but the result will be a flickering PopupMenu :-( So what else could i do to refresh/repaint
