(will do it tomorrow anyways)
if it appear to behave well i think it could be tried to make it go in</pre>

I've played around with a default plasma-desktop and tested the constrained size hint with a local version of the quicklaunch applet that makes use of it. Unfortunately I haven't found the time for a more systematic and thorough testing …

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I poked around the IconWidget class and came up with the following patch that
implements handling of constraints in sizeHint(...). It basically pulls the
code that determines the icon size for a given widget size out of
layoutIcons(...) into an the a new iconSizeForWidgetSize(...) method so that
it can be reused by sizeHint(...).
I've also changed the signatures of elidedText(...) and layoutText(...) by
removing the need to pass a QStyleOptionGraphicsItem*, since it wasn't used
there anyway. If there's some reason why this could be a bad idea, I'll put it
back in.
The patch changes the behavior of sizeHint(...) in the following way:
- If there is no constraint, the behavior remains unchanged.
- Likweise, the minimum and maximum sizes are unaffected by constraints. I
don't see how limiting the available width/height would affect either one?
- The preferred size computation now uses the constraint to compute the
expected size of the icon and adjusts the returned value accordingly.
I must admit that I'm not entirely happy with the solution as it has (at
least ;) the following issues:
- The reported preferredSize is not bounded by the maximumSize. Unfortunately
I can't call maximumSize() and its derivatives from within sizeHint, since
this might cause QGraphicsLayoutItem to update all sizeHints, which might in
turn lead to unbound recursion, since it apparently also caches the
previously passed constraints :/
This is why I'm setting any unconstrained dimension to QWIDGETSIZE_MAX for
the purpose of determining the icon size that fits within.
- I'm not very fond of having to initialize and pass around
QStyleOptionGraphicsItem objects, especially since they are apparently only
used for determining whether we've got an RTL layout.
Any testing / feedback would be greatly appreciated.</pre>
