[PyQt] stylesheet sub-controlls
Hi, are there stylesheet sub-controlls in pyqt like in qt? For example the widget Qprogressbar in qt got the sub-controll chunk, but i cant find anything like it in pyqt.

Re: [PyQt] pythonw crash trying to run demos
Even if it seems to be a working example from the book, you might want to provide the source code for us. Make sure we can try to reproduce the problem. Can you run at least another example program to show your installation is working? Please also try to use text emails, not html. Best, -Christoph Am Dienstag, 23.

Started the examples and demo = crash in pythonw. The IDLE shell works OK. Windows restart not helped. Any ideas?

Mainly laziness on my part. I need to write some handwritten code to deal with immutable strings. I'll add... QXmlQuery.evaluateToString() - str ...to tonight's snapshot. None will be returned if the evaluation fails. Phil It's OK for evaluateToString(), thank you. but evaluateToStringList() returns None, Is it normal?

[PyQt] Run a job in background
Hello everybody, I'm starting with the PyQt programming so my knowledge on this is not very broad at the moment, then I'm asking for some help if possible :) Well, here my problem: I'm programming a GUI to collect some variables for afterwards running a long and time consuming process (like 2h maybe). The main window is done and the job is ready to be launched. I have a button connected to a function that calls an external program with the variables gathered. What I'd like to do is: when I click this button, it opens a new small window that can control the process (stoping it if necessary, tracking the process with a progress bar and receive piped errors). But what I actually have is that when I click this button it launhes the process blocking the main window losing all control. I have to kill the job and the window if I want to stop it. So, my questions would be: - How can I open that small window to receive and track the process? - How to connect the function (at the moment outside the main class) to the progress bar and to that small window? - How to launch the external program in background mode without blocking all the windows? I'd really appreciate some help on this! I'm quite lost and the documentation is really confusing... Thank you very much in advance!

Re: [PyQt] stylesheet sub-controlls
Hello Lennart,
By subcontrols, do you mean something like:
qpushbutton { color: white; }
qpushbutton:pressed { color: black; }
?
If so, you can set the same stylesheet to a widget as in the regular Qt,
it has little to do with PyQt itself, since the stylesheet is just a string
to be parsed.

Re: [PyQt] stylesheet sub-controlls
Hi,
thank for the response... i found the answer by myself by now XD
self.baraction.setStyleSheet(QProgressBar
{background-color: white;
text-align: center;
color: black;
border: 2px
solid black;
border-radius: 6px;}
-
QProgressBar::chunk{background-color: green;
-
border-radius: 3px;}
)
my problem was that i didnt get it that the string itself is kinda like
in c++, i wrote the syntax like python code and since this didnt work i
started thinking it wouldnt work at all
