Hi there,
I build a gnome canvas where i put a lot of=20
gtk_text_buffer in it, applying some tag on it...
Here is relevant part of the code, which is called many times :
/*Create a gtk_text_buffer */
curText =3D gtk_text_buffer_new(NULL) ;
gtk_object_ref(GTK_OBJECT(curText));
/*insert text in it*/=20=20
gtk_text_buffer_get_iter_at_char(curText, &iter, 0);
gtk_text_buffer_insert(curText, &iter, content, -1);
/*Create a tag for this comment*/
tag =3D gtk_text_buffer_create_tag(curText, "comment");
gtk_object_ref(GTK_OBJECT(tag));
/*Set tag specifications*/=20=20=20=20=20=20=20=20
gdk_color_parse(item_color[0], &gdkColor);
gtk_object_set(GTK_OBJECT(tag),
"foreground_gdk", &gdkColor,
"font", comment_font,
NULL);
=20=20=20=20=20=20
/*apply tag to buffer*/
gtk_text_buffer_get_bounds (curText, &start, &end );
gtk_text_buffer_apply_tag(curText, "comment", &start, &end);
=20=20=20=20=20=20
/*Create an tktext canvas with this buffer*/
item =3D gnome_canvas_item_new(group,
gnome_canvas_tktext_get_type(),
"x", (gdouble)DEPTHTAB,=20
"y", ypos,
NULL);
gnome_canvas_item_show(item);
gnome_canvas_tktext_set_buffer(GNOME_CANVAS_TKTEXT(item), curText);
But when i'm trying to destroy the main application, i obtain the
following=
:
Gdk-CRITICAL **: file gdkfont.c: line 219 (gdk_font_unref): assertion
`priv=
ate->ref_count > 0' failed.
GLib-CRITICAL **: file gcache.c: line 160 (g_cache_remove): assertion
`node=

Any idea where i forget something !
Thanks.

Date: Mon, 2 Apr 2001 13:17:34 -0300
Helllo all,
There is something that is happenig with my version of Glade (0.5.11
obtained from the sources) that I think it is very strange.
When I place a pixmap, the widget pixmap, I choose a diretory, usually
pixmaps inside my application dir (i,e. project1).
But I compile the code with make, make install and when I try to execut=
e it
shows mw the following..
**WARNING**` Could=B4t find pixmap file` project1/file.xpm
It tries to find the pixmap in a diretory that don=B4t exists and I hav=
e
never configured anywhere in the Glade environment or sources codes.
Glade automatically put the =B4project1/file.xpm=B4 in the interface.c=
file in
order to create the pixmap.
Question ..
How can I change this? Because I can=B4t say the place of my pixmaps an=
d a
entire program is not working due to it.
If I edit the source of interface.c Glade overrides it the nest time I =
save
inside Glade.
Thank you very much for your help.

Hello all,
I=B4ll answer my own question
The program was configured to run with gnome support.
I take off Gnome support and it worked out.
If in the future I ever try to run a Gnome program I post this question=
again..
Sorry for your waste of time.

Yes, it is more efficient. (with some more memory use to save CPU
time.)
Erm, `the new GtkTextView' -- does it mean it comes with gtk 2.x? And if
yes, do you know of any workarounds for 1.2? My program is supposed to
work
on DNA sequences, which, as you may be aware of, are sometimes quite
huge.
Still, editing large sequences will probably happen not very often, and
I
wouldn't like to break compatibility -- most systems ship with gtk 1.2.
Any
ideas? Right now even a small 1MB text file is already sometimes a
problem :-(
There are various replacement text widgets available, such as
GtkExText.

Hi,
Both tktext-port and the canvas item are pretty
unmaintained/unfinished, you should be willing to hack on them if
you're using them. They'll need some debugging. Lots of fixes in the
main GTK version of the text widget that aren't in the tktext-port module.

Subject: Transparent Window Focus
I've written a test program to teach myself gtk. A red block appears on
the screen, 50 pixels square. If the user moves the mouse over it, the
block will attach itself to the mouse, and when you move the mouse, the
block will follow it. The problem is, the window focus only applies to
the red block, although the window is resized to the entire screen.
Also, if you move the mouse fast enough, it the block will detach itself
from the mouse. (It can be reattached by moving the mouse over it
again).
I want to be able to define which areas of the window are 'focusable',
the way I can define transparency with a mask. And I'd also, more
importantly, I'd like to fix the 'detaching' problem.
Thanks.
The source for the program follows:
#include <gtk/gtk.h>

Dear Sirs,
I am fairly new to GTK+ and GNOME programming and I wonder how to get
the background.image of the panel (if any) set in the Panel-properties.
The filename will do but GdkPixbuf or map is preferred.
Thank you,
