[pygtk] gnome application
I would like to write a gnome application using gnome-python (without glade) but I havn't been able to find any examples or documentation showing how to do it. I can only find examples from a couple years ago, showing how it used to be done the old way with the earlier version of pygtk and with the deprecated from foo import * statements. The reason I want to go through this without glade is to have a better understanding of what is going on under the hood. Can anyone point me to some example code or documentation showing how to do this? --Doug Blanding___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/

Xavier- Thanks for your suggestion. You are right. There is an example there called appwindow.py which builds an application window pretty much like what I want, complete with menubar, toolbar and statusbar. But I am thinking there is a call to gnomeui.App (or something like that) which creates the application window automatically (complete with menubar, toolbar and statusbar). According to some old documentation I read, you used to be able to do this. But now with pygtk2 and the new python-gnome, I haven't seen any examples or documentation to show how to do it. --Doug Blanding ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/

I have tried the bonoboui example and played with it a little. It certainly seems to provide a nice UI. I guess I was just afraid of it because I don't know anything about bonobo (what it is or why I need it). I suppose I'll just need to learn more about bonobo windows.

In gnome-python tarball, it's in examples/bonobo/bonoboui No, I think that most people are trying to use BonoboUI as little as possible. The new menu and toolbar APIs in GTK+ 2.4 are meant to replace - The old GTK+ menus and toolbars - The libgnomeui menus and toolbar - The libbonoboui menus and toolbars. This is all my opinion, but I think you should just use libbonoboui if you want to create an embeddable GUI component, or us libbonobo if you want to do some difficult multi-threading interprocess-communication stuff.

Re[2]: [pygtk] High CPU problem example
Hi!
I'm not sure what's your problem but I had have one of your problems:
The create_pango_layout is not supposed to be called all the time..
For that, my class caches the layout:
class Message:
def __init__(self, msg):
We are expecting unicode message strings
self.msg = msg.encode('utf-8')
# create a font description
self.font_desc = pango.FontDescription('Serif 8')
def _make_layout (self, widget):
global wrapmode, wrapwidth
# create a layout for your drawing area
self.layout = widget.create_pango_layout(self.msg)
self.layout.set_wrap(wrapmode)
self.layout.set_width(wrapwidth)
# tell the layout which font description to use
self.layout.set_font_description(self.font_desc)
def _make_cache(self, gc):
This method doesn't seems to be fundamental, but..
global depth
#self.image = string.join(self.mx*3*self.my*['\0'],)
#self.image = gtk.gdk.Pixbuf(gtk.gdk.COLORSPACE_RGB, False, 8,
self.mx, self.my)
self.image = gtk.gdk.Pixmap(None, self.mx, self.my, depth)
self.gc = gc
colormap = gc.get_colormap()
white = colormap.alloc_color('white')
yellow = colormap.alloc_color('yellow')
black = colormap.alloc_color('black')
gc.set_rgb_fg_color (yellow)
self.image.draw_rectangle(gc, gtk.TRUE, 0,0, self.mx-1, self.my-1)
gc.set_rgb_fg_color (black)
self.image.draw_rectangle(gc, gtk.FALSE,0,0, self.mx-1, self.my-1)
gc.set_rgb_fg_color (black)
# draw the text with the draw_layout method
self.image.draw_layout(self.gc, Message.BORDER_SIZE,
Message.BORDER_SIZE, self.layout)
def drawon(self, atx, aty, widget=None, gc=None):
if not self.widget:
if not widget or not gc:
return
else:
self._make_layout(widget)
self.widget = widget
self._make_cache(gc)
# draw the text with the draw_layout method
#widget.window.draw_layout(gc, atx, aty, self.layout)
#self.image.render_to_drawable (widget.window, gc, 0, 0, atx,aty,
self.mx, self.my, gtk.gdk.RGB_DITHER_MAX, 0, 0)
widget.window.draw_drawable(self.gc, self.image, 0, 0, atx, aty,
self.mx, self.my)
This creates the layout and dumps it, with a frame into a pixmap that's
later used to be draw anytime.
I removed some code, but that should be enough.
It's from the class Message of IMFish(.sourceforge.net) :-)
Also, i think that you should setup what font do you want
to use, in other place, than the expose-cb!
Seeya!

Subject: Re: [pygtk] High CPU problem example
Hello Gustavo !
Thanks for your answer.
Your solution works fine for my simplified problem. It also pin-point the source of
my troubles.
But in order to solve my original problem I need a further tip:
Indeed If I actually draw something based on the modified font by adding the line
area.window.draw_layout(self.gc, 10, 10,
self.area.create_pango_layout(TEXT))
Nothing is drawn at all if moved to the area_realize_cb routine.
In my real area_expose_cb routine I draw many things with various fonts that are
set-up in other windows
For example I call draw_axes_s which uses 2 types of fonts.
def draw_axes_s(self, xo, yo, xs, ys ):
Draw axis and write down the labels on the screen
win=self.area.window
mini=self.Cld.mini
maxi=self.Cld.maxi
mindist=self.Cld.mindist
markers=self.Cld.markers
location=self.Cld.location
f_mrkX=markers[0][0]
l_mrkX=markers[0][len(markers[0])-1]
f_mrkY=markers[1][0]
l_mrkY=markers[1][len(markers[1])-1]
xsize=min(max(float(xs)/(maxi[0]-mini[0])*mindist[0]*.9,self.min_size),self.max_size)
ysize=min(max(float(ys)/(maxi[1]-mini[1])*mindist[1]*.9,self.min_size),self.max_size)
# Draw the lines
self.gc.foreground =self.area.get_colormap().alloc_color(black)
win.draw_line(self.gc, xo, yo, xo+xs, yo)
win.draw_line(self.gc, xo, yo, xo, yo-ys)
#Draw ticks
for m in markers[0]:
col=(location[0][m]-mini[0])/(maxi[0]-mini[0])
win.draw_line(self.gc, xsize/2+xo+col*(xs-xsize),
yo,xsize/2+xo+col*(xs-xsize),yo+3 )
for m in markers[1]:
col=(location[1][m]-mini[1])/(maxi[1]-mini[1])
win.draw_line(self.gc, xo,-ysize/2+yo-col*(ys-ysize), xo-3,

Well, gnome windows are usually avoided by most developpers. You should consider using bonobo windows instead.

OK, but now I still have my original question. Can an application window be built using a call to gnomeui.App which will automagically give me the consistent and slick look and feel of a Gnome Application (menubar, dockable toolbar, etc) using a simple command or two like in the bonoboui example? (And if so, can anyone point me to some documentation or example code showing how?) I also now have another question: What is it that most developpers know that causes them to want to avoid Gnome windows? Maybe if I knew that, I wouldn't be asking the first question. --Doug Blanding ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/

Some uses bonobo for embedding but not all. Now, I missed that improvement in gtk 2.4 so that may make sense to think about it twice. ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/
