Change background color in GtkTreeView
Hello, I'm working on UI for embedded system using GTK+ 2.24. I want to change GtkTreeView background (area behind rows, which is by default white) to match default color of window area (grey by default). I retrieved GtkStyle associated with GtkWindow and looked for this particular tint of gray color in GdkColor arrays in GtkStyle instance (gb, fg, base arrays). Then I assigned these colors to GtkTreeView using gtk_wdget_modify_base(), but I was unable to find the same color.

New to GSettings
Hello! I'd like to take advantage of GSettings in my application, but I have some questions about it. Ther's a tutorial based on gnome-utils, but it doesn't explain everything. 1. What's the purpose of 'path' attribute? When browsing Baobab's source code I saw, that it set 'path' with '/apps/baobab/', so it's not a file system path, but some abstract representation of settings hierarchy, right? Are there some common categories of paths: 'apps', 'system', 'desktop' or other? 2. When using GSettings I need to install my schemas somewhere. In Baobab's configure.ac they use pkg-config to obtain path: pkg-config --variable gsettingsschemadir gio-2.0 . The problem is, that on my Ubuuntu (glib v2.26.x) there's no such variable... 3. What happens with settings stored using GSettings API, when user will remove my application from system? Will they stay in backend's settings database or after removing schema from schemas directory backend will remove settings related to it from it's storage? ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

This property is changed all the time by internal code, and whole object is locked for e few seconds by a couple of functions in my library. While object is locked by one this functions other threads should be able to check object's status all the time. To do that I'm going to use GStaticRWLock. The problem is that, I'm not sure where how can I mix functions used to deal with GStaticRWLock with my object's implementation.

However I haven't wrote any library so far, so I haven't got any experience with it. :( After reading libtool documentation I became a bit confused, because I don't know what kind of library should I build. My library should be linked with program while compilation process, not loaded during runtime, so I thought, that I must build a static library, but libraries such as GTK+ or GLib in /usr/lib directory have *.so prefix. I don't understand it... :( Can someone explain it for my? What kind of library should I build? (Sorry for posting it on this mailing list, but i don't know any reliable source of information. Moreover we can say, that it's someway linked to GTK+ apps programming, because I'm using GLib ;P) -- Cya!

GMutex vs GStaticMutex
Hi! I'm not sure if I understood difference between these two types of mutexes. Can someone explain it for me more clearly, that it is in GLib's documentation ;) Next thing, I have program, which will run few threads (one thread - one object), so each object need to have it's own mutex, which will be better for me GMutex or GStatisMutex? -- Cya!

Please don't say me, that I was so stupid all the time :| Let say that we
have such function:
static void
maman_ibaz_base_init (gpointer g_iface)
{
static gboolean initialized = FALSE;
if (!initialized) {
/* create interface signals here. */
initialized = TRUE;

I'm quite young programmer (it's my hobby only), but I'm almost sure, that
all variables declared inside function are destroyed when function execution

return TRUE;
}
gint thread_fun (gpointer data) {

It doesn't work form me. Progress bar is pulsing, but when event source is
removed something weird starts happening. Whole application still works, but
GUI doesn't update (new progress bar's text doesn't display). Any idea how
to solve this?! Maybe I'm too stupid...

Weird problem with GTK+ 2.10.6
Hi there!
Maybe problem, which affect isn't a bug in GTK+, maybe it's occurred by
something else, I don't know. Here's short description. I write small multi
thread application in C language. Whole code is based on GTK+/GLib and
GObject. I have problem with dealing with GtkProgressBar. Window, which
contains GtkProgressBar widget is created in separated thread. Firstly i
make this progress bar pulsing for a while using g_timeout_add () and after
few seconds I remove this source and try to set progress bar's fraction to
0.0. after executing gtk_progress_bar_set_fraction () GUI starts behaving
very funny. Whole program still works, it creates new windows but it doesn't
show widget inside those windows and doesn't update already existing widgets
(when I move mouse pointer on already existing button etc.), it looks like
this:
http://img509.imageshack.us/img509/5880/zrzutekranury1.png
This is normal behavior (when gtk_progress_bar_set_fraction () is removed
from code):
http://img217.imageshack.us/img217/4130/zrzutekranu6vj6.png
when in situation on first screenshot I click in place, where normally is
OK button, program behaves normally ?!
Here's some code:
*this function creates window: **

Re: (Easy?) Newbie enquiry re: pointers
06-10-10, Samuel Cormier-Iijima [EMAIL PROTECTED] napisał(a): Yea, I wasn't sure whether to put a :-( or a :-) ( :-) ). The thing is, strings getting copied around so often seems like memory waste to me... when it passes the text to Pango, does that keep a pointer itself? freetype? how many times is the same text kept multiple times in memory? i guess for strings it doesnt really matter because it's not that much memory wasted. Still, gnome/gtk's memory usage seems pretty high (see ReducingMemoryUsage on the wiki) GTK+ is basen on GObject, which stores most of parameters with GValue. If you will look how GObject's objects works, you will see, that if they are well implemented, they will release used memory every time, when we will try change value of some parameter, which is allocating memory (like strings in GtkLabel). Moreover I must say, that you aren't completely right saying, that GTK+ based programs leaks memory, or that their memory usage is high. If you are working with some GTK+ application, you can see, that whole program allocates pretty much memory, that is right. However it doesn't mean, that this program uses whole allocated memory whole the time, because it doesn't, it use only some part of it and rest is treated as buffer for future memory usage. Such behave makes GLib based programs (GTK+ is based on GLib, but GLib provides memory management subsystem, so GLib is responsible for memory usage) faster, because they doesn't need time for physical allocating and releasing memory. Programs are faster (at least theoretically), but they allocate more memory then non GLib programs, so for some of us it will be waste of memory and for rest not. Note, that Pango uses GLib too. -- Pozdrawiam! Tom ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

GObject - problem, as usual
Hi!
I'm writing some application based on GObject and I have problem when I'm
trying to destroy object. I have two object A and B, A derives from GObject
and B derives from A. I declared my own finalize methods for both objects,
but when I'm destroying B object only B finalize function is executed. When
I remowe B finlize function declaration from B_class_init () A finalize
function is executed normaly. Why B finalize method overrides A finalize
method and what should I do to remoe this overriding? Maybe some parts od my
code will be helpful:
GType A_get_type (void) {
/*PRINT_DBG_IN_FUN_NAME*/
static GType type = 0;
if (type == 0) {

sizeof (AClass),

NULL, /* class_finalize */

0, /* n_preallocs */
NULL/* instance_init */
};
type = g_type_register_static (G_TYPE_OBJECT,
AType,
info, 0);
}
return type;
}
GType B_get_type (void) {
/*PRINT_DBG_IN_FUN_NAME*/

NULL, /* class_data */
sizeof (B),
0, /* n_preallocs */
NULL/* instance_init */
};
type = g_type_register_static (A_TYPE,
BType,
info, 0);
}
return type;
}
static void B_class_init(gpointer g_class,
gpointer class_data)
{
PRINT_DBG_IN_FUN_NAME
GObjectClass *class = G_OBJECT_CLASS (g_class);
GParamSpec *spec;
g_type_class_add_private (class, sizeof (BPrivate));
class-constructor = B_constructor;
class-dispose = B_dispose;
class-finalize = B_finalize;
class-set_property = B_set_property;
class-get_property = B_get_property;
/* other code */
}
static void A_class_init (gpointer g_class,
gpointer class_data)
{
PRINT_DBG_IN_FUN_NAME
GObjectClass *class= G_OBJECT_CLASS (g_class);
GParamSpec *spec;
class-finalize = A_finalize;
class-set_property = A_set_property;
class-get_property = A_get_property;
/* other code */
}
I changed objects names, to make it more legible. PRINT_DBG_IN_FUN_NAME is a
macro, which display function name in console. Here is otput of running
'g_object_unref (g_object_new (A_TYPE, NULL))'. This is program output:
Function: A_class_init
Function: B_class_init
Function: B_constructor
Function: B_dispose
Function: B_finalize
I noticed, that in both *_class_init fnctions I use GObjectClass to declare
finalize, constructor etc. functions on it, is this main reason of my
problem?

Hi! Well, I'm working with GTK+ quite long, but I have never tried to get inside it's code. Now I'm trying to understood how GObject works and I must say, that it isn't as easy as I tought ;) I read few times Gobject tutorial provided with GLib's documentation but I don't understood it enouhg good, maybe because I don't like (and know) object languages, I know only C++ basics. So these are my questions: I. What the Interfaces are? I don't understood their predestination? I understood them as other type of Methods, but I'm know, that Interfaces aren't Methods, can someone explain me it? II. For example, object XXX inherits from object ZZZ and I defined *_finalize () functions for object ZZZ, but I didn't define any *finalize functions for object XXX. What will happen if I'll try to destroy XXX object? Will ZZZ's *_finalize functions will be used? III. What 'GTypeInstance' is? -- Pozdrawiam!
