Icon alignment in MessageBox

Is there a way to top-align the icon in MessageBox?

Write your own message box

Seriously, if you look in message_box.py you will see the message box is just a normal QDialog. The layout of its contents is done using self.gridLayout which is QGridLayout. Changing the alignment of the appropriate cell in that will do the trick.

Well, yes, that's what I'm trying to do, but I can't find how to change the alignment of a cell. I've managed to get the desired result with this:

Code:

box = MessageBox(...)
box.gridLayout.addWidget(box.icon_label,0,0,Qt.AlignTop)
box.exec_()

but this does not look (codewise) right, it's adding a widget that's already there, not directly changing the alignment, and I just feel lucky that the icon is not duplicated. Simply using setAlignment(Qt.AlignTop) in various places didn't cause an error, but didn't work either.

Adding the same widget multiple times is not problem, as when you add a widget it is automatically removed from its previous parent.

What you need is

self.gridLayout.setAlignment(box.icon_label, Qt.AlignTop)
