Editor created by QStyledItemDelegate is not inheriting container width

[Colin James]

I'm currently working on a program that has an editor component built on a QListView that uses a QStyledItemDelegate to draw the item in the list. I'm using createEditor to create another widget for editing the selected list item's contents but, no matter what widget I use, it does not inherit the full width of the list cell.

I've looked at all the layout and geometry settings to no avail.
Below is an image that demonstrates the issue:

As you can see, the editor widget is offset to the left by quite a bit. My understanding was that the editor is just an overlay and should inherit the region/rect that the delegate has.

Any insight would be much appreciated.

I eventually managed to fix this by implementing updateEditorGeometry and calling editor->setGeometry(option.rect);. I should have looked into base class member functions sooner!
