It is relatively easy. You need a QWidget-detived widget that will collect
mouse up/down events and store pixel data. Color is set by setting a pen via a
toolbar. After that you can incorporate zoom/scaling and additional tools.
Some of the questions though are do you want it to be raster (as ab

Hi,
I'm new to both Python and PyQt and still learning the ropes (familiar with
C++, though). What I'm trying to do is to create a QTreeWidget where some
items are widgets (say buttons for this example's sake).
When I try this code (snippet):
cw = QTreeWidget()
The fader widget is limited. What you really want to do is create a parent
QWidget or QStackedWidget subclass and have it call render() on both widgets,
then fade with one on top of the other with the one being faded to on the
bottom (by decreasding the opacity of the top) until it is complete t

Not only that, but the last time I built it against a current version of Qt
it didn't work any more, at least not in the way I expected. :-/

The only difference is it is a fade against a solid color. You could create the

This is a curious issueI have two Macs, both of which I've upgradef from
PyQt 4.5.1 to 4.5.4. Running my application on my MacMini was just fine
this morning. Just now, I fired up the exact same code on the MacBook Pro
for the first time after the PyQt update and the QtNetwork calls seem to

Hi, i've installed PyQt4 (Py2.5-gpl4.4.3-1.exe) on Windows.
That release has sql support, and i use the ODBC driver. I know it

But in this particular computer, when i run the same code that works
in the others, i get the following err
Ok, again, curious issue on my end.
It turns out these requests *were* working, just really really slowly...like
60 seconds for a simple GET. I'm inside a different network today, so I

Hi,
I'm new to PyQT ( GPL v4.4.3 for Python 2.5).
Could someone point me to a piece of code which demonstrates how I can
set-up a connection to an MS Access and a simple SELECT query, using
QtSql?
I work in a Win32 environment.
Thanks very much.
Bernard.
