pixmap memory leak in X server

Mike Wyer — Sat, 21 Dec 2002 21:03:15 -0000

Gtk::Pixmaps don't appear to free up their allocated
memory in the X server until the program exits, even if
they are "destroy"ed while the program is running.

The following code will cause the X server to bloat
(RSS goes from 35M (inc 32M framebuffer), to 300M in
about 30s). Just give it a filename for a picture (any
old jpeg will do).

Obviously this only affects code that creates and
destroys lots of pixmaps, but my little image browser
can easily crash the X server when it runs out of memory.

#!/usr/bin/env ruby

require 'gtk'
require 'gdk_pixbuf'

im = Gdk::Pixbuf.new(ARGV[0])
window = Gtk::Window.new(Gtk::WINDOW_TOPLEVEL)
frame = Gtk::Frame.new("Mem leak test")
widget = Gtk::Pixmap.new(*im.to_pixmap_and_mask)
frame.add widget.show
window.add frame.show
window.show
count = 1
Gtk::timeout_add(100) do
tmp = frame.child
if tmp
frame.remove tmp
tmp.destroy
GC.start
end
widget = Gtk::Pixmap.new(*im.to_pixmap_and_mask)
frame.add widget.show
count +=1
count <= 50
end

grab_focus don't work ?!?!

Anonymous — Tue, 10 Sep 2002 17:57:42 -0000

With the following code grab_focus does not work :
def initialize
vb = Gtk::VBox.new
@textwin = Gtk::Frame.new
@textwin.add(vb)

@scrollwin = Gtk::ScrolledWindow.new(nil, nil)
@scrollwin.set_policy(Gtk::POLICY_AUTOMATIC,
Gtk::POLICY_AUTOMATIC)

vb.pack_start(@scrollwin, true, true, 0)

@text = Gtk::Text.new
@text.set_editable(false)
@text.grab_focus

@scrollwin.add(@text)

@input = Gtk::Entry.new
@input.grab_focus
@input.signal_connect('activate') do
input
end
vb.pack_start(@input, false, true, 0)

@textwin.show_all
end

failed to compile bc of rb-gconf.h

Sat, 06 Jul 2002 03:16:07 -0000

My compile of ruby-gconf doesn't get very far as I get
this:

make[1]: Entering directory
`/home/eliot/downloads/ruby-gconf-0.2/src'
gcc -fPIC -g -O2 -
fPIC -O3 -Wall -I/usr/local/include -I/usr/include/gtk-1.2 -

make[1]: Leaving directory `/home/eliot/downloads/ruby-

I'm using Debian
Linux, unstable. Line 83 is:

void
default_error_handler(GConfClient*, GError*);

I
commented the line out and the compile went on (and got errors
from other spots because the line was missing). I don't see
anything wrong with the line... what am I missing?

gdkevent type in ruby-gtk-0.28

Anonymous — Thu, 27 Jun 2002 04:18:24 -0000

I use ruby-gtk-0.28.
I want to get a double click event through
Gdk::BUTTON2_PRESS but I cannot get it.
I think with the following script
e.type should have Gdk::BUTTON_PRESS
or Gdk::BUTTON2_PRESS or other,
but it has Gdk::EventButton.

%cat test.rb
require 'gtk'

w = Gtk::Window.new
b = Gtk::Button.new("test")
b.signal_connect("button_press_event"){|w, e|
p e.type
}

w.add b
w.show_all
Gtk.main

I think rbgdkevent.c should have following lines.
+static VALUE
+gdkeventbutton_type(self)
+{
+ return INT2NUM(get_gdkevent(self)->button.type);
+}

+rb_define_method(gdkEventButton, "type",
+gdkeventbutton_type, 0);

Other Event class such as GdkEventKey
should be changed too.

Gtk::CList.set_row_data

Matthias veit — Mon, 17 Jun 2002 08:11:09 -0000

Hi,

the update of clist (set_row_data) does not work.
See the attached example:

List.repaint uses set_text for each column - that works.
List.repaint1 uses set_row_data - nothing happens.

Best regards,
Matthias

rbgtklayout.c fix (oops..)

Anonymous — Sun, 12 May 2002 13:28:49 -0000

oops..
here is the diff

rbgtklayout.c fix

Anonymous — Sun, 12 May 2002 13:24:19 -0000

Gtk::Layout.vadjustment should be
layout_get_vadjustment, NOT layout_get_hadjustment

Gtk::CTreeNode

Matthias veit — Sat, 27 Apr 2002 10:12:05 -0000

Hi,

the CTree does not work as expected, because the
identity of its subnodes (CTreeNode's) changes
permanently:

def testEquals(ctree, row)
gtknode1 = ctree.node_nth(row)
gtknode2 = ctree.node_nth(row)
assert(gtknode1 == gtknode2)
end

will raise an exception.

This is pretty uncomfortable, because the whole
model has to be mirrored, to know which item is meant
by a specific row.

The generated wrapper for CTreeNode's, should
implement the == operator to be able to work with
Hashes and Arrays.

libglade & gnome-widgets

Matthias veit — Thu, 25 Apr 2002 11:35:32 -0000

libglade works perfectly for all gtk-relevant widgets.
It is not possible to use any gnome-widget, I always
got the warning:

** WARNING **: unknown widget class '<widget>'

I use the cvs-version of libglade (I tried the last
ruby-gnome 0.27 too - the same) and ruby 1.7.2
