Re: [pygtk] Trouble with widgets in a canvas
The canvas does not always work well with no-window widgets (ones that
paint themselves directly onto their parent's window (done for speed)).
The easiest way around this problem is to pack the widget inside a
GtkEventBox.
Alternatively, if you just want a bit of text on the canvas, you may as
well use the text canvas item:
item = canvas.root.add('text', text='Some text', x=42, y=21,
font='some-x-font', fill_color='red',
anchor=ANCHOR_SW)
The other benefit of this is that the text will be shaped rather than
being enclosed in a solid colour rectangle. Note that for
GnomeCanvasText, the (x,y) coords give the position of the anchor point.
You use the anchor property to set where the anchor is located.
James.

[pygtk] Trouble with widgets in a canvas
Hello,
First off, I'm a brand newbie and it's possible that all I need is a
reference. Secondly,
here it goes:
I was trying to modify the canvas example that came with pygnome.
Instead of creating rectangles I wanted to create a label and drag it
around. The trouble is that the label doesn't
seem to be redrawing itself. In fact, if I minimize and then
un-minimize, the label disappears.
Do I need to connect to some event or something? Here's the code and
what I've got installed:
% rpm -qa | grep py
pygtk-libglade-0.6.3-1
python-devel-1.5.2-7
pythonlib-1.23-1
pygtk-0.6.3-1
pygnome-1.0.50-1
python-1.5.2-7
python-docs-1.5.2-7
Any help would be appreciated.
-Doug

As soon as your have circular references I'm supposed to be looking into support for weak references for Python (which I've been too busy to look at so far). This is definately one of the more important applications; I'll be keeping this in mind. -Fred -- Fred L.

Re: [pygtk] pyglade/libglade ignores default-width/default-height ?
I suppose I should put in a message stating that the pyglade module is deprecated. It is probably better to use the libglade module, which uses libglade rather than being pure python. It handles the default_width and default_height attributes correctly.
