Re: DGSEAL_ENABLE: replace direct addressing in statusbar
Oh, woops, just glanced at the documentation, well, I guess you could leave it with the -label for now, and once 3.0 comes, switch over as both the method and GSEAL stuff will be in place at that point. You could always write the code for the transition now and add a preprocessor check like so: #if GLIB_CHECK_VERSION(3, 0, 0) // new code which gets the box's child #else // old code you pasted in the mail #endif On Sun, 04 Jul 2010 06:57:48 +0100 Carlos Pereira jose.carlos.pere...@ist.utl.pt wrote: On 07/04/10 06:17, Nader Morshed wrote: statusbar = gtk_statusbar_new (); label = gtk_statusbar_get_message_area (GTK_STATUSBAR (statusbar)); gtk_misc_set_alignment (GTK_MISC (label), 0.5, 0.5); Thanks Nader, I believe you are in the right path (although the documentation actually says this returns a box, not a label): http://library.gnome.org/devel/gtk/stable/GtkStatusbar.html#gtk-statusbar-get-message-area Anyway this has been added in Gtk 2.20, I am still running 2.18.3, lots of users also, it might be better to wait...

Window move at menubar in Gnome
Hello, since I installed Ubuntu 10.04 I noticed that I could move windows while dragging the menubar in Gnome. I like this feature. But I don't use Gnome, but Enlightenment 17. I would like to implement support for this feature in E17, but I don't know which calls are behind this on X level. I tried to find some documentation about it, but failed. Before I start to dig into Gtk+ code I hope someone on this list could answer this question. regards Andreas ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
GTK/GDK equivalent to UpdateWindow() ?
Anyone who's familiar with the MS Windows API will know that it contains a function called UpdateWindow(). A call to UpdateWindow() forces the specified window's client area to be repainted immediately (i.e. bypassing any other messages or operations that may be pending for the window). Is there any equivalent functionality within GTK+? John ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Thanks guys - but if I'm reading the documentation correctly I don't think either of those calls is quite right. gtk_widget_queue_draw() seems to be roughly equivalent to InvalidateRect() in Windows (i.e. it schedules a window to be repainted at some point in the near future - though not necessarily immediately). gtk_events_pending() seems to be more useful for ensuring that GUI operations don't get bottlenecked while there's a lengthy operation being processed. Neither of those is quite what I need. I'm looking for is a function that will force a window to be repainted at once, before any other pending events get processed. Thanks.

There is hardly any reason why you would want to do that, unless you want to write very bad code. But if you insist, probably gdk_window_process_updates() is what you need.

Actually John, it's the same problem that I had in my other thread (where I was trying to draw a now line onto a scrolling canvas). Here's what I wrote at the time:- I'd like the viewport to have a vertical now line (similar to the play head on a tape recorder). At the moment, this is drawn onto the canvas. Therefore every 1/30th second, it needs to be erased, then the viewport needs to be adjusted, then the now line needs to be redrawn. This produces a very flickery now line. Upon closer inspection, the now line isn't really flickery; it's actually wobbling slightly, from side to side. I suspect that the erase stage is being queued and not really taking place at the right time (i.e. the now line hasn't yet been erased by the time the scrolling movement takes place). So before trying your suggestion of utilising a pixmap (which might be quite difficult to achieve, due to the window needing scroll bars and stuff) I thought I might try to 'force' a redraw, immediately after the erase stage (just so that I can be certain it's actually being done, and not simply being queued). gdk_window_process_updates() does look as though it should work (assuming it does still do something). In fact, it looks as if it was designed precisely with this kind of scenario in mind. I'll give it a try and see what happens. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
How to hide the sub-menu title of a GtkComboBoxEntry ?
I created a GtkComboBoxEntry with GtkTreeStore. The problem is, the
sub-menu have a title whose value is the same as it's parent. How could I
drop this title?
I notice that a GtkComboBox example in gtk-demo without this title, it's
done by by gtk_cell_layout_set_cell_data_func () which have a parameter of
GtkCellRenderer * 。But is there a way to get the renderer from
GtkComboBoxEntry?
Here is an example:
#if 0
gcc -Wall -O2 -o main main.c `pkg-config --libs --cflags gtk+-2.0`
exit

abc,

};

{
GtkTreeIter iter, iter2;
gint i;
GtkTreeStore *store = gtk_tree_store_new (1, G_TYPE_STRING);
for (i = 0; i ARRAY_SIZE(list); i++)
{
gtk_tree_store_append (store, iter, NULL);
gtk_tree_store_set (store, iter, 0, list[i][0],-1);
gchar **str = (list[i][1]);
for (; *str != NULL; str++)
{
gtk_tree_store_append (store, iter2, iter);
gtk_tree_store_set (store, iter2, 0, *str, -1);
}
}
return GTK_TREE_MODEL (store);
}
static void is_capital_sensitive (GtkCellLayout *cell_layout,
GtkCellRenderer *cell,
GtkTreeModel*tree_model,
GtkTreeIter *iter,
gpointer data)
{
gboolean sensitive;
sensitive = !gtk_tree_model_iter_has_child (tree_model, iter);
g_object_set (cell, sensitive, sensitive, NULL);
}
int main (int argc, char *argv[])
{
