Re: [PyKDE] Python functions as slots

2002-09-30 Thread Soeren Fietzke 

Hi Konrad,

just leave out the receiver object:

app.connect(button, SIGNAL("clicked()"), foo)

Re: [PyKDE] QMessageBox and Qt3

2002-06-06 Thread Soeren Fietzke 

That is expected: in Qt 2.x, a modal dialog would silently call exec() on show(), in 
Qt 3.0, this does no longer happen (which is a
documented change).
Doing an mb.exec_loop() instead of mb.show() should fix it.

Soeren

You mean the PyQt book by Boudewijn Rempt? That can be found here:
http://stage.linuxports.com/projects/pyqt/

The official Qt Documentation that was supposed to be released last year will not 
appear in printed form, but it is part of the Qt
online docs (just print the pdf version (ftp://ftp.trolltech.com/qt/pdf/3.0/) if you 
want something on paper :).

Hi Oliver,


the indentation of "slotFile" looks incorrect to me. You define that function inside 
the __init__ function, not in the class block.
Or, if you want it defined there, do not use "self" with slotFile (because it is not a 
class member function then).

Note that "a" is a reference to a QString object, not a Python string.
The following should work as expected:
 print str(a)==b
