[PyQt] QTextBrowser.append(mytext) ??
Hello, I found an example with the following line: self.browser = QTextBrowser() #some code self.browser.append(blabla) why does that work? nor i did find a QTextBrowser - method append in the qt-assistant, neither in the pyqt-class reference. (http://www.riverbankcomputing.com/Docs/PyQt4/html/qtextbrowser.html) thanks a lot for any hint. beste gruesse jochen ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

Re: [PyQt] Memory leak when using QAbstractTableModel
2007/12/23, Phil Thompson [EMAIL PROTECTED]: Is there anything that can be done? Not if I can't reproduce the problem. I'm using current SIP and PyQt snapshots and Qt 4.3.3. It also works for me on windows, using the latest binary. But have you tried it on linux? I'm using ubuntu 7.10, which uses gcc 4.1.3.

Works fine here on Debian unstable, with a bit older PyQt4(I think from November) and Qt4.3.2. Yes the memory usage increases when starting to scroll, but not that much. After scrolling from one end to the other on both bars the python process is still under 30MB of res-memory according to top. Andreas -- Time to be aggressive.

I see that behaviour, but a C++ version behaves in the same way so it's not a PyQt problem.

I'd like to do something like this: http://doc.trolltech.com/4.3/qstyle.html#drawComplexControl in PyQt4. Is it the right approach? Approach... Well, I'd suggest you re-think your approach a bit. Anything non-standard is - Yes, non standard to user which have to learn how it works - You're somethat likely to fail to meet quality plank of the rest of Qt (mouse events, prelight, styles, resizing etc). Think of how do you apply a different style to your application, if you have lots of custom drawing. - As you can see, many widgets use QStyle to draw themselves, it's larger design than you probably want. - You may encounter conflicts with Tree widget drawing. - You may end up with larger and harder-to-debug, harder-to-support code (rather then doing the standard way). Me thinks you have to have good reasons to do custom drawing, Oleg ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
