[pygtk] pygtk-1.99.3
I have just uploaded a new pygtk tarball. This fixes many of the crashes people had with the 1.99.2 release (these were mainly due to inadequate testing after merging the python22-branch). The package will soon be available from: ftp://ftp.gnome.org/pub/GNOME/earthquake/sources/pygtk/ Like before, this release requires python >= 2.2a4 and gtk+ >= 1.3.9 (plus its dependencies). Main features of this release: - crash fixes (me, msw) - fix reference leak in last reference handling (me) - gobject.new wrapper (msw) - make code generator output #line statements, so errors in the overrides file give correct line number/filename (me) - split type definitions out of pango, gdk and gtk defs files so that other modules which need to know about the type definitions of some other module don't need to parse all the function/method defs (this speeds up builds slightly). (me) - add many missing wrappers (msw, zilch) - bug fixes (lots of people).

[pygtk] [patch] PYGTK_NO_THREADS patch
Hi James, The attached patch adds a check for the environment variable PYGTK_NO_THREADS and disables threading in runtime if it is set. This is a very important patch to the orbit-python team because it will allow us to run clients that are also CORBA servers and thus can service requests. With this patch and Johan's ORBit-Python patch we can actually run the echo test server with gtk.mainloop and have it work perfectly. James, if you would rather have a bug created for this, just answer or /topic on IRC. Thanks.

parse_color isn't enough. Basically, it just fills in the red, green and
blue members of of the GdkColor object. In order for the colour to be
usable, it needs to be allocated in the widget's GdkColormap.
Currently you can do this with "widget.get_colormap().alloc(colour)".
This will set the pixel member of the GdkColor, which is the index into
the widget's colormap (or for TrueColor visuals, just the packed
representation of the colour). This is what is really used by these
routines.
For 0.6.x, this process was all handled by the GdkColormap.alloc() method.
I haven't yet written the wrappers that would make GdkColormap.alloc in
1.99.x act this way as well.
James.

Re: [pygtk] how to set widget's foreground color?
No, you're changing the style that the label is using when drawing itself on its parent.

That means you want to modify the *label* inside the button:
import gtk
def click(b, *args):
label = b.get_child()
b.modify_bg(gtk.STATE_NORMAL, gtk.gdk.color_parse("red"))
label.modify_fg(gtk.STATE_NORMAL, gtk.gdk.color_parse("green"))

gtk.main_quit()

window.set_title("title")
window.connect("destroy", mainquit)
close = gtk.Button(label="press me!")
close.connect("clicked", click)
window.add(close)
window.show_all()
gtk.main()

Yeah, I guess I would be surprised, since I was hoping to change the color
of the text in the widget, not the background of the button. ;-) Calling
modify_bg does change the background color of the button, but that's not
quite what I was after.
Maybe I should have phrased my question differently. How do I change the
text color in a button? I thought that would have been covered by asking
how to change the foreground color in a widget. Given this code:
import gtk
def click(b, *args):
gc = b.window.new_gc()
color = gtk.gdk.color_parse("red")
b.modify_bg(gtk.STATE_NORMAL, color)
color = gtk.gdk.color_parse("green")
b.modify_fg(gtk.STATE_NORMAL, color)
def _test():
window = gtk.Window(gtk.WINDOW_TOPLEVEL)
window.set_title("title")
window.connect("destroy", gtk.mainquit)
close = gtk.Button(label="press me!")
close.connect("clicked", click)
window.add(close)
window.show_all()
gtk.mainloop()
if __name__ == "__main__":
_test()
after I click the button, when the button is in STATE_NORMAL, the background
is red, however the text is still black.

You'd be surprised, but it's actually the background that you want to
modify here.
w.modify_bg(gtk.STATE_NORMAL, color)

I came up with this:
#!/usr/bin/env python
import gtk
def _on_expose(drawingarea, event):
# get the GdkWindow
window = event.window
# get the GC
gc = window.new_gc()
# create a green color
color = gtk.gdk.color_parse("green")
# use this color for drawing
gc.foreground = color
# draw a line
drawingarea.window.draw_line(gc, 0, 0, 200, 200)
# the usual stuff
win = gtk.Window()
win.connect("destroy", gtk.mainquit)
win.show()
# create the drawing area
drawingarea = gtk.DrawingArea()
drawingarea.connect("expose-event", _on_expose)
drawingarea.show()
win.add(drawingarea)
# enter the mainloop
gtk.mainloop()
Everything seems to work (no errors), but the line is drawn in black. Note
that the DrawingArea widget doesn't support draw_* directly. I had to dive
into the underlying Gdk widget for that.
Suggested fix(es)?

[pygtk] how to set widget's foreground color?
How do I set the foreground color of a widget without using rc files or
strings? I've tried this (w being a displayed gtk.Button instance in my
example)
gc = w.window.new_gc()
color = gtk.gdk.color_parse("red")
w.modify_fg(gtk.STATE_NORMAL, color)
and
gc = w.window.new_gc()
color = gtk.gdk.color_parse("red")
gc.set_foreground(color)
but neither had any effect. I'm using the 2.0 API and the new
ExtensionClass-less PyGtk API.
Thanks,
