Problems with demos
I biult gtk+-2.10.13 with DirectFB1.1.1. Examples of DirectFB work well. Gtk demos also work, but the image on the display is wrong. It seems like width of image doesn't fit screen width and lines are shifting. But for all that testpixbuf-drawable demo also works well. Any suggestions about correcting it? ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
question on using GtkCellRendererProgress
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi all, I've got a gtk_list_store, and one of the columns I want to make a progress meter. I'm gathering that I use teh cell rendered GtkCellRendererProgress for this column. But I have 2 points of confusion. 1) When I create the table (gtk_list_store_new()), what is the G_TYPE I use for this particular column defn ? 2) How do I refer to this column in a gtk_list_store_set() (i.e. yes, I know I refer to the column number, but what do I pass in for a value ?)

There can be several columns just for a single cell renderer.
Those are the column numbers, I use the next enum for a gtk list store:

enum

cell = gtk_cell_renderer_progress_new ();

GtkTreeIter iter;

COLUMN_VALUE, 40,
COLUMN_TEXT, blah, /* see

Voilà, something that uses these function.

how to tell if to GtkTreeIter's point to the same row, or not?
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, I have an application, where, to facilitate looks deep inside callbacks, I store the Iter of a row as and when I gtk_list_store_append() it. This allows me to gtk_list_store_set() using the saved iter, and it works quite well. Now, I have a case, where I want to popup a popup-menu when the user clicks on a row. So I attached a button-press-event to the gtk_tree_view. In my callback I do a gtk_tree_view_get_path_at_pos(), and then I map the path to a row/iter using gtk_tree_model_get_iter(). This appears to work fine, except that the iter I get returned is not identical to the iter that was earlier saved when row was first gtk_list_store_append()'ed (the stamp, and user_data are the same, the other fields differ). I am using the saved iter to locate a private data structure relating to the row. I suppose that I could g_object_set_data() a pointer to my private data structure insize the iter, but that seems otherwise unnecessary. (My list private data structures have the saved iter in them, so was just comparing the saved iter against the one from the model_get_iter() returned iter.) Is there a way to compare iter's, or am i better to store a g_object_set_data() inside the iter to point to my private data structure ? thanks and best rgds, - -Greg - -- +-+ Please also check the log file at /dev/null for additional information.
