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!

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,
[pygtk] Someone have used gtk.IMContext ?
Is there some example?
I'm doing:
im = gtk.IMContextSimple()
im.set_client_window(some_gtk_window)
im.filter_keypress(a_keypress_event)
and then:
im.get_preedit_string()
returns :
('', PangoAttrList at 0x833d3f0, 0)
(after passing a few keypress)
I don't know if I shoould call something more, to initialize them,
or if I should connect something.. or what..
And I can't found information on this gtk functions.
Also, note, that it says that I shoould pass (**string,*attrs,*pos),
but, after tryng that, it says that it requires no arguments, and,
doing in that way, it returns the 3-upla above.
Thanks in advance, for anything!

[pygtk] help: how to build text from keypress and dead/compose keys ?
Hi! I hooked key_press event.. and all was ok until I wanted to 'handle' deadkeys .. well actually.. the deadkey event comes as a keypress. But I can't handle it, I could save it for later use.. but still don't know how can I use that when other key comes. When a keypress comes I do: 1. check it's a keypress event 2. check if keyval 0xff00 == 0xff00, if it's that, - contrrol key 3. if not control key: 4. oldstr = oldstr + unichar(gtk.gdk.keyval_to_unicode( keyval )) Well I must check that keyval_to_unicode doesn't return 0L. But, is keyval_to_unicode the function that I should call? I saw that there are some gtk_im_context methods/classes.. are them for this kind of things? (i don't found information about that functions).. Is there some kind of value that I can keep, to process next keypress with, in order to apply the char modification?

Oh, I see what you want now. The method mentioned in the FAQ about
including other .def files is really the recommended way to do this.
Look at something like the gnome-python/gnome bindings from CVS or a
source tarball (e.g nautilus.override or something similar) to see how
it includes classes from other modules. The required header files will
be installed somewhere under ${prefix}/include/ is you have the
appropriate *-devel packages installed (depends on your distribution).
second: where should I take the pygtk's codegen from? I used the one
from my debian's python-gtk2 source packages, but have had lots of
problems (for example, doesn't have autoget.sh, to automake/confs
problems..).. so i wanted to checkout, if there exists some stable
version?
Whatever comes with the pygtk sources is really the official version
and it works well for its purpose (generating the gnome-python
bindings).
Periodically I think that it may not be crazy to release it as a
separate package, since the .defs format is good for many language
bindings (it is used by a couple of others) and is relatively simple to
create for extra packages. I have an unreleased thing at the moment I
am working on where I used the .defs format to create the Python
bindings. But I have the same problem you do -- it creates an implicit
pygtk dependency for a package that doesn't use pygtk.
Mmmh.. the module I made, doesn't seems to import pygtk, is this
enough?:
I don't think you are responding to the comment I wrote. :-)
Mmh.. I answered that, because, i think that you were talking about a
runtime reference :-). Maybe because, I saw, in one of the faqs, that for
using the module created, one should import pygtk before importing the
module created.
Talking about packages, I also think that it's not crazy to release
python-gtk's-gen separated! :-)
Related question, is the def files's format one known or standard format?
Well, at least, binary packages from debian:
ii python2.3-gnom 2.0.0-5Python bindings for GNOME 2
ii python2.3-gtk2 2.0.0-2Python bindings for the GTK+ widget set
Seems to doesn't have codegen installed :-(
You possibly need the development package for pygtk as well. I am not
familiar enough with Debian's packaging scheme to know for sure.
Ok, and, as Charles said, it's on python-gtk2-dev has pygtk-codegen!
Thanks for the answers!

[pygtk] Making librsvg bindings..
Hi! Today I were trying to make these bindings. Finally, with a coctail of good luck, faqs and faqs, some other packages etc.. .. I made them work.. Well I have a couple of questions: first: if i want to reuse objects returned by it, then, I should use the .defs and .override definitions that pygtk's codegen builds? Is there another, more.. manual way to do? second: where should I take the pygtk's codegen from?

Well.. finally i couldn't have working with the 1.11. faq section.. i did all but.. i couldn't finnish that cause i didn't have autogen.sh, i tried running autoconf aclocal automake.. finally taked an autogen.sh frrom python-gnome, but when it runs automake said: can't find Makefile.am (the file was there..) .. well .. lots of problems.. :-( Then i checked the faq on ibm's site, referenced in 1.11, and handled to get it working..

[pygtk] Question about idle_add() and refreshing some widget..
Hi! I'm making a program that has only a widget that's a GtkDrawingArea. In that widget I draw my own objects. Well, I want it to be refreshed as fast to produce some smooth efect in the objects that are moving inside. For drawing the objects inside i've put a expose callback function. And, until yesterday, I was using a timeout callback to queue a draw event. Timeout set to 30 ms. It was very cpu consuming. So I changed it, to queue draw events on a idle callback, if an update flag is set, and I set that flag from a timeout callback. Why? Because the idle loop was executed too many times, so I have this restricted to a timeout.. Well, at this point, the problem is that it keeps using too much cpu! :-) so, i don't know what should I do. I've seen that there are some gtk's idle_add_priority function, but I don't have that one in python-gtk2 2.0.0-1, debian's module. And also I'm not sure if using that is the right way to do the things. Maybe this question is more gtk-related than pygtk. Well, anyway, I think that with idletimeout implementation that I did, the cpu wasting I have is constant when I draw more objects on the DrawableArea.. Well, that's all, thanks in advance! alejandro -- + There is no dark side of the moon really.

[pygtk] Can't get key-press-events..
Hi. I'm using python-gtk21.99.17-3 on debian. The problem is that i can't get keypress events, and, i'm getting the button-press-events in right way. I'm tryng to get them, on a subclass of gtk.DrawingArea. The code is this: self.connect(expose-event, self.area_expose_cb) self.add_events(gtk.gdk.BUTTON_PRESS_MASK) self.add_events(gtk.gdk.KEY_PRESS) self.connect(button_press_event,self.someevent) self.connect(key_press_event,self.someevent) #self.connect(key-press-event,self.keyevent) I'm not too familiar with python-gtk, i make all the tests that could help. the first: button-press-event works correctly. I tried without the button_press.. Also i tried wrapping my DA subclass on a gtk.EventBox.. but keeps failing. Well.. any help would be appreciated. Now i'm going to check te value of gtk.gdk.KEY_PRESS. Thanks a lot. david -- + There is no dark side of the moon really.
