Hello again,
I'm still wondering if I don't quite 'get it' as to how Python does
things. I have the following where 'sourceMessage' is a QLineEdit and
'mainTextWindow' is a QTextEdit:
def doUpdateSources(self):
self.sourcesMessage.setEnabled(1)
self.sourcesMessage.setText("Updating your sources, please wait...")
os.chdir("/etc/apt/")
self.mainTextWindow.setEnabled(1)
self.mainTextWindow.setText(commands.getoutput("apt-get update"))
self.mainTextWindow.append("Done!")
self.mainTextWindow.scrollToBottom()
self.pbSaveMain.setEnabled(0)
self.mainTextWindow.setReadOnly(1)
This works but not as I expect it to work. I thought this would first
display the the text in 'sourceMessage' before moving on line by line
(changing directory, do the 'apt-get update' etc). But it seems like
it's going through the entire function before actually output anything,
the display everything when it reaches the end. So I guess I've fallen
in the trap of old-time thinking again...
So what I want it to do is to display the 'please wait' in the
sourceMessage *before* doing the 'commands.output', just as this little
console script does:
import commands
def test():
print "Please wait"
print commands.getoutput("apt-get update")
print "Done"
test()
For the whole shebang (pun intended), should someone want to take a
look, I have ziped up everything at:
