Re: gnomedesktop.org?
I assume you mean gnomedesktop.org - looks like it got the registration updated (check whois gnomedesktop.org) by a Luke Stroven yesterday. I don't know him, but he seems to be the legit owner (http://stroven.org/about.php). Perhaps it's just a glitch by the Registrar? I'd give it a day or two before people flood him with email.

Re: Remarks on gtk docs
Joost, and others, I tried learning to use gtk, gdk, cairo, pango, etc several years ago and was frustrated by the difficulty in getting good docs, sample code, etc. Even worse was finding that constant change meant me having to rewrite code fairly often. Note that I'm an old guy who has written code for a living since I was a young guy. But this has been the most difficult venue in which I've tried to work. I feel and share your pain in producing something of quality and lasting value. I know it can be done, but I pretty much work alone, and it's not easy. I switched to writing my own set of widgets in C++ which more or less look and act somewhat like Java's AWT, but nowhere near as powerful yet. I've got simple projects like a telnet client working, but I feel like I'm mining gold with a fork. My one big question to this list is (and no disrespect is meant), is there a elist similar to this one dedicated to Xlib programming? This list does have many very talented people, some of whom I'm in awe of. But I'm veering into a different direction and just need pointer towards that direction. adTHANKSvance, Ed James On Wed, Feb 17, 2010 at 7:06 AM, Joost 1...@depikt.net wrote: ... own use.

Re: Not getting which mouse button is pressed on button-press-event
Just tried it and verified most of the answer, via something I'm playing with;
UINT ejEventManager::getButton () {
return currEvent.xbutton.button;
}
1 == Left mouse button
2 == Right mouse button
4 == scroll up
5 == scroll down
Wasn't able to emulate middle button on my 2-button mouse (project for another
day, perhaps). Can't verify 6,7, but perhaps it's time for me to buy a better
mouse. I wonder, though, if this might be useful with a joystick (left, right).

Hello.
You can get the mouse button pressed by looking at event-button
field. 1 means left button, 2 middle button (which can usually be
emulated by pressing right and left button at once on 2-button mouse),
3 right button. I think 4-7 mean wheel movement (check API docs for
that, I'm not 100% sure).

Re: OT comprehending large application (was What, in detail, the GDK do)
One way might be to write a real application (even if it's just a Hello World display) and drill down through the source code to see how this seemingly small amount of code works at lower and lower levels. While this sounds easy, it's quite a learning experience, and IMHO is well worth the time spent.

Re: Memory problem
Don't know if this will solve your problem but I found:
gdk_color_alloc is deprecated and should not be used in newly-written
code. Use gdk_colormap_alloc_color() instead.
My guess is that gdk_color_alloc allocates memory which isn't being freed up
and thus accumulates, but I didn't dig very deep. This might also happen
with the newer function.

Hi,
I see memory usage is biger and biger during the same code running:
int main(int argc, char* argv[])
{
gtk_init(argc, argv);
GtkWidget* window;
while (TRUE)
{
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_widget_set_app_paintable(window, TRUE);
gtk_window_set_resizable(GTK_WINDOW(window), FALSE);
gtk_window_set_keep_above(GTK_WINDOW(window), TRUE);
gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);
gtk_widget_set_size_request(window, 200, 200);
gtk_widget_realize(window);
gtk_widget_destroy(window);
}
gtk_main();
return 0;
}
If there are bugs in gtk_widget_destroy? It sames that the memory is not
freed.
Wants help.

Re: g_main_loop
Just a guess, but I'd try putting a function in Thread 1 that emits the signal, but call that function from Thread 2. This way, Thread 2 controls when the signal is emitted, but the signal is still handled by Thread 1. Never actually tried this myself, though, so I don't know for sure if one thread can call a function in another thread.
