problem when setting several times a pixbuf in a gtk image
Hello,
I use the following function to draw a frame in a gtk_image:
static void draw_frame (long int frame_nbr)
{
GdkPixbuf *pixbuf;
const BYTE *rgb;
PClip vclip_rgb32 = ToRGB32::Create(vclip);
CPVideoFrame frame = vclip_rgb32-GetFrame(frame_nbr);
guint width = frame-GetDimension().GetWidth();
guint height = frame-GetDimension().GetHeight();
rgb = frame-ReadFrom('~').ptr;
gtk_widget_set_size_request (image, width, height);
pixbuf = gdk_pixbuf_new_from_data (rgb,
GDK_COLORSPACE_RGB, TRUE,
8, width, height, 4 * width,
(GdkPixbufDestroyNotify) g_free,
(guint8 *)rgb);
gtk_image_set_from_pixbuf (GTK_IMAGE (image), pixbuf);
g_object_unref (G_OBJECT (pixbuf));
}
The first time that I use this function, there's no problem, the pixbuf is
drawn.
But when I call this function another time, it segfault during
gtk_image_set. Does someone see what is wrong ?
thank you
Vincent Torri

Size of text entries
Hello, In my app I have a text entry widget that will display a small number, usually 1-10. However, when I added the entry widget I noticed it was very big compared to the amount of text that will be stored in it. Also I should mention the user will not be changing the text inside the entry but the computer will. My question to you is, is there a way I can change the size of the entry? If not than are there any alternative widgets out there that are suitable for what I want to do (i.e. small text box, user doesn't change text inside)? -- ~flood ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Hi all,
I'm trying to use GtkTreeView's fixed height mode for a playlist that
can hold thousands of items, but I'm having a bit of trouble. All I
seem to get is:
Gtk-CRITICAL **: gtk_tree_view_insert_column: assertion
`gtk_tree_view_column_get_sizing (column) == GTK_TREE_VIEW_COLUMN_FIXED'
failed
I've tried gtk_cell_renderer_text_set_fixed_height_from_font() (I have
three columns, all text renderers), but no help there; I still get the
above critical message.
This works for me:
gtk_cell_renderer_text_set_fixed_height_from_font(GTK_CELL_RENDERER_TEXT(renderer),1);
if((tree_col=gtk_tree_view_column_new_with_attributes(_(Pos.),renderer,
text,SEQUENCE_TABLE_POS,
foreground-set,SEQUENCE_TABLE_TICK_FG_SET,
NULL))
) {
g_object_set(tree_col,
sizing,GTK_TREE_VIEW_COLUMN_FIXED,
fixed-width,40,
NULL);
col_index=
gtk_tree_view_append_column(self-priv-sequence_table,tree_col);
}
else GST_WARNING(can't create treeview column);
I was initially using gtk_tree_view_insert_column_with_attributes() and
got lots of assertions too. In this case it seems to be required to
create the column, set the fixed-width and append (or insert) it.
That sounds kinda icky. Where are you getting the value of '40' for the
'fixed-width' parameter? Just making it up?
Unfortunately, I *can't* use fixed-width columns, as the user needs to
be free to resize the containing window (and the treeview should resize
to match, with the middle column growing or shrinking as necessary). I
still don't understand why GtkTreeView requires a fixed *width* column
in order to enable fixed *height* mode.

If I set the sizing of each column to GTK_TREE_VIEW_COLUMN_FIXED, I get
4500 blank rows, and only the middle column header is visible (probably
because I set its 'expand' property to TRUE). Not too useful.
I'm not understanding why fixed height mode has anything to do with the
sizing mode, since (according to the docs[1]), the sizing mode is only
used to determine the _width_ of the cell, not the height.
Can someone enlighten me here?
Thanks,
Brian
[1] The sizing method the column uses to determine its *width*. Please
note that GTK_TREE_VIEW_COLUMN_AUTOSIZE are inefficient for large views,
and can make columns appear choppy. (emphasis mine)
