about main event loop
hello, I don't know how to deal with the signal when I clicked the icon on taskbar with right button of the mouse the program runs ok, but it gives the warnings in the console: GLib-WARNING **: g_main_context_prepare() called recursively from within a source's check() or prepare() member. GLib-WARNING **: g_main_context_check() called recursively from within a source's check() or prepare() member. should i use a callback function to deal with the signal button_press_eventor create a thread to run in the idle time? ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: about main event loop
No, you don't create threads to handle events. Instead you connect to callbacks through g_signal_connect(). But in order to get an intelligent reply from this list, you should provide a complete compilable program that exhibit the problem that you experience.

Re: GtkTreeView in VBox
Hi, I have also faced a similar situation in which case i need to pack a treeview inside a VBox. I would not mind the treeview apis not working but the packing is something i am looking to keep. The scrolling of the VBox works fine for smaller sizes of the TreeView. But when the treeview consists of elements greater than a certain number of elements (450) in my case, the scrolling goes awry between adjustment values 16000 and 27000 (sounds strange, i know.). Please help. Any suggestion is welcome. Thank you for your time.

Is this expected/supported use case or am i doing something wrong here? Thanks for your time. No, it's not a supported use case. GtkTreeView and other scrolling widgets such as GtkIconView are meant to be placed directly in a GtkScrolledWindow. Not doing so will, for example, break scroll commands given by GtkTreeView itself, since it is not directly connected to the GtkScrolledWindow anymore. Such scroll commands are given when you are setting a cursor on a row and want to make that row visible, automatic scrolling during drag selection, or by the application programmer using the gtk_tree_view_scroll_to_cell() and related functions, etc. Another reason why this is a bad idea is memory usage, although I cannot tell for sure whether this still holds for GTK+ 2.18 and later. For earlier versions of GTK+ a large X window has to be allocated if you are placing a GtkTreeView with a large number of rows in a VBox or similar container. regards, -kris. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Nobody ever used GTK_STOCK_FILE?
I wonder why
GTK_STOCK_COLOR_PICKER
GTK_STOCK_DIALOG_AUTHENTICATION
GTK_STOCK_DIRECTORY
GTK_STOCK_DND
GTK_STOCK_DND_MULTIPLE
GTK_STOCK_FILE
GTK_STOCK_MISSING_IMAGE
are not included in the array
GtkStockItem builtin_items
in the source file
gtkstock.c
How they are expected to be used when they cannot be found by
gtk_stock_lookup?
Should not be added at least
{ GTK_STOCK_FILE, NC_(Stock label, _File), 0, 0,
GETTEXT_PACKAGE },
and maybe also
{ GTK_STOCK_DIRECTORY, NC_(Stock label, Folder), 0, 0,
GETTEXT_PACKAGE },
?

As far as I can understand this, some stock icons are not meant to be
used as items. For example, having File stock item doesn't make much
sense, since files usually carry their own name and this is what
should be displayed. Another example are DND icons. I really cannot
imagine situation where menu item with DND stock icon would make
sense.
BTW, I'm not the one who decides what becomes item and what not.

simple internalisation (was: Nobody ever used GTK_STOCK_FILE?)
For example, having File stock item doesn't make much
sense, since files usually carry their own name and this is what
should be displayed.
Most programs have the File menu item in the tool bar.
To create menu items from stock items is a simple way to present
translated labels for all languages supported by gtk at least for the
frquently used items, without need to manage translations to all those
languages for the application.
What I am doing is this:
GtkWidget* menu_item_new_from_stock (const gchar *stock_id) {
GtkStockItem item;
if (gtk_stock_lookup (stock_id, item)) {
return gtk_menu_item_new_with_mnemonic (item.label);
}
return gtk_menu_item_new_with_mnemonic (stock_id);
}
...
// *** menu items in menu bar
editMBMenuItem = menu_item_new_from_stock (GTK_STOCK_EDIT);
preferencesMBMenuItem = menu_item_new_from_stock
(GTK_STOCK_PREFERENCES);
helpMBMenuItem = menu_item_new_from_stock (GTK_STOCK_HELP);
...
But because this does not work for GTK_STOCK_FILE,
I am using this:
#include libintl.h
#define T_(String) dgettext (gtk20, String)
...
fileMBMenuItem = gtk_menu_item_new_with_mnemonic (T_(_Files));
...
Other frequently used words are available too, for example
searchMBMenuItem = gtk_menu_item_new_with_mnemonic (T_(Search));
Some other words are translated for gtk properties and for glib,
so I am using also this:
#define L_(String) dgettext (glib20, String)
#define P_(String) dgettext (gtk20-properties, String)
for example:
settingsMBMenuItem = gtk_menu_item_new_with_mnemonic (P_(Settings));
