Re: [PyQt] need help with sizing QStackedWidgets
Would appreciate some help here. I don't like how these stacked widgets take up all of this vertical space when the window is resized. I have tried setting a size policy to minimum on the stacked widgets but no luck. On Fri, Aug 23, 2013 at 4:02 PM, Eric Frederich eric.freder...@gmail.comwrote: Here is a small example.

Re: [PyQt] need help with sizing QStackedWidgets
Replying to self with a solution in case someone else comes across this problem. david_boddie on freenode's #pyqt channel helped me out. A solution was to call layout.setRowStretch(len(labels), 1) ... after adding the spacer. Another solution was to nest the grid layout into a BoxLayout and call addStretch.

[PyQt] PyQt 5.1 App doesn't exit after QQuickView closed
Hi,
In the following example, the application doesn't exit after the QQuickView
window is closed. Is this the correct behaviour or is it a bug? This is using
snapshot-693a95fde3fa on OSX 10.8.4 with Qt 5.1, PyQt 5.1 and macports python
built as 32 bit.

[PyQt] Using SWIG to wrap application written in QT
So I have this application that I'm writing that uses the Qt libraries. I want to wrap the my application and all of it's objects so that I can call it from a scripting language quickly, be it python, or ocaml or whatever. Anyway, for the last bit I've been trying to get a module compiled that will allow me to dynamically call into the classes functions that I've defined. SWIG seems to work right, and recently I even got my own self defined class within a module from my C++ source to run, although it segfaulted and I have yet to find out exactly why. Can this be done? I mean, I was wondering it would be more appropriate that I use SIP. One of the problems that I'm facing (I think) is that some arguments to my classes and functions are Qt objects. But I can't export those functions in my SWIG module without also writing a wrapper to the Qt objects manually (is that right?). I'm very new to SWIG, but I definitely need the speed of a scripting language for my development, because the compile cycle with Qt and C++ is slow. In addition, I'm kind of considering SIP in parallel, so I need advice as to which is more appropriate. Can anybody advise me what the best route is in order to get what I want? SIP or SWIG?___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
