Zoom - what is the best way to do this?
My app will be used by people of differing eye sight levels so requires the kind of zoom you get on other applications (e.g. IE and drawing applications). Is there a more elegant way than just going through all the items on the window and resizing them? (Currently just had a listWidget and a couple of buttons, purpose-built very simple UI).
You could place your whole UI in a QGraphicsView and use "QGraphicsProxyWidget":http://qt-project.org/doc/qt-4.8/qgraphicsproxywidget.html#details to embed QWidgets there. Then zooming should be as easy as calling scale on the graphicsview/scene.
Fab, I will try that :-)
Or you can zoom by changing font size:
QFont ff = this->font();

Since this would only work on controls with text on them, I'm not sure it's a good idea for increasing accessibility for partially sight-disabled. You'd need to take care of all other controls with individual hacks (tool-buttons, controls with custom paint event, labels that show images, etc.).

and I proposed this.
This may change in the future. And apart from that, he was asking for elegant solutions. Elegant solutions partly are elegant because they catch corner cases implicitly.
Morning people, hope you had a good looooooooong weekend.
Have not managed to get this working yet but been side tracked (and on holiday) - thanks for your thoughts. I will try them out.
I'm a girl by the way ;-)

I'm a boy, just in case :)
DerManu - sorry to be a pain but do you have a simple example? I have been through about 10 different examples and not got anything working (putting everything in the a QGraphicsView and scaling the view).
Never mind - I was being dim, my view was going out of scope.
