[PyQt] Stop main window from showing when closing dialog
Hi, I'm working on a background application that sometimes show a dialog in a lower corner, most of the time it's meant to just sit queitly in the taskbar or system tray. My problem is this; When the dialog in the corner is closed the main window get the focus again and becomes the top window, stealing it from whichever window had it before. The corner window doesn't take the focus when shown which is correct. Now I just need to stop the main window from receiving the focus when the corner dialog is closed, or failing that loose it directly after getting it. I tried setting parent to None when calling QDialog.__init__ for my corner dialog but then it didn't show up at all. If anyone has any idea how to fix this I'd greatly appreciate it.

[PyQt] Different png formats?
Hi, I'm trying to get my application working fully after freezing it with cx_Freeze, but I'm having weird troubles with images. Some png's load fine, others stop working after freezing. I'm attaching two examples. Ar there different ways of encoding pngs? Is the support these different ways in different Qt modules?

Hi, As I understood it png support is built-in and doesn't need a module for that. Might have changed since that mail thread was written though.

Most probably, your app suffers from missing Qt image format plugins, or, equally likely, cx_freeze failed to include them in a way, that Qt is able to use them properly. You might try PyInstaller, that is prepared for such (Qt/PyQt) needs.

[PyQt] Hunting down memory leaks
Hi, I'm currently developing a little tool and it seems I have a memory leak somewhere along the line that handles images, so each leak is around 7mb which is kind of a big deal leading my app quickly to 100mb. I'm wondering if any of you havea any tips to figure out what kind of object I'm leaking and where I'm leaking them. I'm new to python, Qt and PyQt so I'm not very well versed in what tools are available.

Re: [PyQt] Application not hiding from taskbar
I figured out how to solve my little conundrum. My solution is so ugly I'm ashamed but I can't figure out why self.hide() doesn't hide my window in the first place. Here's the final code: def hideEvent(self, event): self.hide() if ph.is_windows(): self.hidden = True self.setWindowFlags(Qt.ToolTip) def showEvent(self, event): if ph.is_windows() and self.hidden: self.setWindowFlags(Qt.Window) self.hidden = False self.show() Kind regards, Mikael On 4 December 2010 00:40, Mikael Modin micke.mo...@gmail.com wrote: Hi, I'm trying to implement minimize-to-tray but my application refuses to hide from taskbar.

[PyQt] Getting information about crash/lockup
Hi, I'm developing a networked multithreaded application using PyQt4 v 4.7.4. I'm wondering if there are any tools available to see what messages/signals are passed internally by Qt or if you can suggest any other good debugging tips/tools. My problem is this: The problem is related to three parts, the main window, system tray icon and a dialog. If I click a button that start things with main window in normal mode or maximized mode and the dialog pops up everything works fine. But If I click the same button, minimise the window to tray and the dialog pops up the main Qt thread dissapear from the Eclipse thread list in Debug perspective. And with it the entire gui. Which at the moment only consists of the system tray icon but I think the thread should keep running. I'm not calling close on the window when minimizing to Tray, I'm just hiding it with setVisible(false) I'm using the pydev extension with Eclipse 3.5.2. The other threads keep running without python exceptions. I don't get any python exception from the main thread. I tried running it through gdb with gdb --args python main.py to see if I could catch an exception, signal something that way, nothing. This makes me think that the thread somehow locks up completely and therefore doesn't show up in Eclipse, but it doesn't crash. /Mikael Modin ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
Re: [PyQt] Getting information about crash/lockup
As per Eriks suggestion I have attached the complete sample. Some more digging by myself and a colleague has shown a solution/workaround as well, but I'm still confused. The behaviour seem to be different from the specification. If you run the attached file you have 2 seconds to minimize the window and then an additional 5 seconds until the dialog closes. If you have minimized the dialog before the dialog closes the app.exec_() returns and the gui thread exits. If you don't minimize the window the dialog will just show up and then close. If you add the line self.setAttribute(Qt.WA_QuitOnClose, False) after the line QDialog.__init__(self, parent) everything works like it should. If you look here: http://doc.qt.nokia.com/4.7/qwidget.html#close it says that this is correct behaviour iff the window doesn't have a parent, but my dialog has my main window as a parent so I don't know why it ignores it and close the whole gui.

I have a minimal sample with the exact same bug. Got it down to 26 lines of code and one icon. I've built and run make install on the latest SIP and PyQt. If you are running Windows I could send you the sample and see if it's platform-specific. The key seem to be to be close the only visible dialog in a function that is called by a timer from a function that is called by a timer. If I move the close() up one step everything works like it should. Timer - Function - Timer - Function - close() I've tried both PyQt and PySide and the error occurs the same way in both frameworks so I assume this is based in Qt and not PyQt.
