Re: How to use pixmaps in GTK+ applications?
My question is, how to use pixmaps in GTK+? Can I make them resouces as in Win32? (As already was said, it's more GTKish (and 100% portable) to convert them into constant C data using gdk-pixbuf-csource. If you really want to use Win32 resources, sure, that should work too. If I use them as ordinary files, how can I know the path after users' installation? What should I do in the configure.ac and Makefile.am? You should install them in a known location I'd suggest just defining a simple directory under $datadir. These replies forgot that the original poster asked about Win32. It is not typical at all to use fixed compile-time pathnames on Win32. (I would go so far as taying it isn't even possible, in general, as there is no drive letter that would be guaranteed to exist on all Win32 installations. My previous home machine had no C: drive, for instance!) Instead, you need to have your app look up its installation location at run-time. Use something like this: wchar_t buf[1000]; gchar *exename; GetModuleFileNameW(NULL, wbuf, G_N_ELEMENTS(wbuf)); exename = g_utf16_to_utf8 (wbuf, -1, NULL, NULL, NULL); to get the path to the .exe file, and then construct the path to the image file(s) from that (assuming your installed installs the image files in a fixed location relative to where the .exe gets installed). (There is also g_win32_get_package_installation_directory(NULL, NULL) which does more or less the same. Read the documentation.) --tml ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Usage of g_str_strip
Hey all, There is a function g_strstrip defined to strip-off the leading and trailing spaces from a string. However, the working of this function is a bit confusing. I have the following code-snippet : name = g_strstrip ( g_strdup (gtk_entry_get_text(GTK_ENTRY (name_entry; g_free (name); Is this leaking memory? I dont understand clearly how g_strstrip works. Do I need to store the g_strdup in a pointer and free it instead of the name? The Devhelp doesnt clearly specify anything about it. Please clarify. Thanks, Sankar P P.S.

Invisible/missing cursor in editable
Hey list, Has anyone here experienced (and solved) a case of missing cursors when inline editing a string in a GtkTreeView?? If so, I would sure like to see the solution.

Please clarify. #define g_strstrip( string )g_strchomp (g_strchug (string)) Both g_strchung and g_strchomp works with the string you passed to it and does not allocate memory.

gtk window size/position on win32?
Quoting the reference on gtk_window_position: If you are saving and restoring your application's window positions, you should know that it's impossible for applications to do this without getting it somewhat wrong because applications do not have sufficient knowledge of window manager state. The Correct Mechanism is to support the session management protocol (see the GnomeClient object in the GNOME libraries for example) and allow the window manager to save your window sizes and positions. Can anyone tell me how one would do this on win32? I've tried manually remembering window position and size (keying off the window's configure-event), but just as the gtk docs say, this does not work quite right. -- Allin Cottrell Department of Economics Wake Forest University, NC ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

I am converting my program to use multiple threads: the primary thread for the GTK stuff, and the worker threads for all the time-consuming work that will be performed in the background. The GUI thread takes input from the user and copies it to a global, shared, synchronized data pool which the worker threads monitor. The workers, in turn, invoke GTK functions to write the results to some list/tree views. The problem I have run into is that the list/tree views are not updating properly. They only show a portion of the data which has been written to their models. If I minimize the app window and then restore it, the missing data appears. What am I doing wrong, and what should I do to resolve it? Are you wrapping all your setters in calls to gdk_threads_enter/leave? For example: gdk_threads_enter(); GtkTreeIter iter; gtk_list_store_append(model,iter); gtk_list_store_set(model,iter,MY_COLUMN,my_data,-1); gdk_threads_leave(); I would have the GUI thread update the list/tree models, but the GUI thread spends most of its time sitting in gtk_main.

Ofcourse it does, Anything that a GTK+ gui does is inside gtk_main(), you can get the gui thread to do the updating by passing the appropriate data to g_idle_add() (the idle handler should run in the thread thats running gtk_main; i.e. the gui thread).
