Delegate size issue.
Message 1 in thread
Hey guys,
I'm using a delegate for my own QListView,
I've reimplemented the paint and the sizeHint function
I'm trying to display two types of cell depending on the "option.state".
- If the list item is clicked it has to be big.
- If the list item is not clicked it's smaller.
But for some reason I can't call the sizeHint function dynamicaly (each time
I click on an item)
or resize anything in the paint delegate function.
Any idea?
Thanks,
Ben.

I did this too. It's a bit of a hack. Here's what you have to do:
Connect whatever appropriate signal for item selection to a slot that
does this to your tree view:
treeView->setRootIndex(QModelIndex());
This will cause sizeHint() to be called on the selected QItemDelegate
(and all others too). The result is that the tree repaints and your item
delegate can resize its cell if it's selected.
You can accomplish the same thing by calling reset() also.

Just a wild guess: Try emitting dataChanged() for your cell, and care
for uniformItemSizes = false.

Hello,
such a question:
I have code that is based on "QX11EmbedContainer" is there a
replacement for it on a mac ?
