A relevant question occurs to me: Do you have your window manager set on "click to focus" or "focus follows mouse"? I have the latter. In any case, I think the behaviour that most users would expect is: when the window you left with an uncommitted edit regains focus, the uncommitted edit would still be there, and still uncommitted. -- 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

Interesting. The machine from which I reported this is running Ubuntu 7.04, with gtk 2.10.11. When I move the mouse pointer out of the treeview window, the cell edit-in-progress immediately disappears and "bottles of coke" comes back. I have another machine running GTK 2.12; I'll check on that, though I'm pretty sure the effect was the same. -- 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 can make the point by reference to gtk-demo: 1. Start gtk-demo and select "Editable cells" under "Tree View". Double-click to get the demo. 2. Click on the "bottles of coke" cell to edit it. 3. Type "foo" (and only that, no Enter). 4. Move the pointer out of the treeview window, then move it back in. My expectation: the unfinished edit will still be in place. Actual behaviour: the "bottles of coke" cell is as it was before I started; my edit-in-progress is gone. This may not be a bug as such, but I would like to know if there's a way of preserving the state of the cell-editing process, in face of the treeview window temporarily losing focus.

Start with the correct signal name:
http://library.gnome.org/devel/gtk/stable/GtkCellRenderer.html#GtkCellRenderer-editing-started
Looking at the documentation should be first thing when you
get a GObject complaint about invalid signal/property name.

Duh, sorry, that should be "editing-started", not "start-editing". Then it works.

start-editing signal?
I'm trying to connect a callback to "start-editing" on a cell
renderer, but I must be doing something wrong. My code is
basically
static void create_cell_renderer (gpointer p)
{
GtkCellRenderer *r;
r = gtk_cell_renderer_text_new();
g_object_set(r, "ypad", 1,
"xalign", 1.0,
"mode", GTK_CELL_RENDERER_MODE_EDITABLE,
NULL);
g_signal_connect(r, "start-editing",
G_CALLBACK(cell_edit_start), p);
}
When this code is invoked, I'm getting
GLib-GObject-WARNING **: gsignal.c:1669: signal `start-editing' is
invalid for instance `0x822a5f0'
I've verified that 0x822a5f0 is indeed the return value from
gtk_cell_renderer_text_new.
Can anyone tell me how to make a valid hook-up? Thanks!

emit keypress event into event loop
Hello,
Anybody has idea how to emit in GTK (2.11.6) some keypress event into
main event loop?
I have mouse clickable button and want to send to my text_view a
keyboard press.
I'm doing this way:
in main code:
g_signal_connect(G_OBJECT(my_button), "button-press-event",
G_CALLBACK(press_callback), G_OBJECT(textview));
in callback:
static void press_callback( GtkWidget *widget,
GdkEventButton *e, GtkWidget *text_view )
{
g_print("button press\n");
GdkEvent *event;
event = gdk_event_new(GDK_KEY_PRESS);
event->key.keyval = GDK_K;
event->key.window = gtk_text_view_get_window(text_view,
GTK_TEXT_WINDOW_TEXT);
event->key.time = 0;
gtk_main_do_event(&event);
}
I get nothing in my text_view view but have the following debug output:
GLib-GObject-WARNING **: invalid uninstantiatable type `' in
cast to `GdkWindow'
gtktextview.c:4303: focus_out_event
>Lines Validated (gtktextview.c:3492)
visible rect: 0,0 226 x 107
invalidated rect: 0,0 226 x 28
>Exposed (gtktextview.c:4447)
or if trying another approach with sending event directly to text_view
widget:
static void press_callback( GtkWidget *widget,
GdkEventButton *e, GtkWidget *text_view )
{
g_print("button press\n");
GdkEvent *event;
event = gdk_event_new(GDK_KEY_PRESS);
event->key.keyval = GDK_K;
event->key.window = gtk_text_view_get_window(text_view,
GTK_TEXT_WINDOW_TEXT);
event->key.time = 0;
g_signal_emit_by_name(GTK_TEXT_VIEW(text_view), "key_press_event",
event);
}
the program seems go in correct way, but I get segmentation fault:
>Invalidate, onscreen_validated = 1 now FALSE (gtktextview.c:3442)
gtktextview.c:3454: adding first validate idle 13
gtktextview.c:3461: adding incremental validate idle 14

If it's got a little brawn, you can probably do everything you want to do through Cairo: http://cairographics.org (if your device is using a version of GTK+ 2.8 or newer). Based on the change of the rotation in your device, you could have it call the ::expose method on a GtkDrawingArea, and simply do whatever drawing in Cairo you wish from there. It's not incredibly powerful, but it's enough for simple animations and such, and it saves you from having to port over a huge canvas widget. If you're using an older version of GTK+, or your hardware doesn't have hardware floating point, performance might not be so hot through Cairo though, and you'll want to look at messing with GdkPixbufs.

which level (directfb or gtk++)shoud I use to draw image?
hello all I am developing a media player on Linux. We choose the Gtk+ based on DirectFB is our GUI library. But I wonder to know which level API should be choosed when draw image on LCD, use Gtk+ object such as GdkPixbuf, GdkImage and so on, or use IDirectFB,IDirectFBSurface and so on? If I want to use the IDirectFB and IDirectFBSurface to draw image on LCD, how can I get these interface from the GDK or Gtk+ object? Thanks for any kind help.
