Custom QItemDelegate that varies height with width
Message 1 in thread
I am creating a custom QItemDelegate that displays rich text. I have
the display working ok, however, I need the height to vary as the user
resizes the width of the view. Unfortunately, the sizeHint for my
delegate only gets called when the item is first displayed, fixing the
height. I assume, since text wrapping is an option on standard
delegates, that this functionality must be available. Does anyone know
how to vary the delegate height as the width changes?
Thank you,
Rob

You have to make a connection from the horizontal header to the model. In the
header, you can get a signal when the user resizes the columns, and you can
then ask the model to change the size of the entry.
