gtk_signal_connect(GTK_OBJECT (clistwidget), "key_press_event",
GTK_SIGNAL_FUNC (on_person_selector_list_key_press_event),
0);
But the method Rene suggested for setting focus (changing
clist->focus_row) will not work in browse mode of the clist. There are
two kinds of focus (marked either by a solid block or by a thin frame)
and changing ->focus_row only changes one of them. I therefore use the
following function which is clumsy, but works. I would like to know if
someone knows of a better way to do this through the public interface.
void GUIBrowse::FocusRow(int position)
{
int oldposition = recipients->focus_row;
if (position == oldposition)
return;
gtk_signal_emit_by_name(GTK_OBJECT(recipients), "scroll_vertical",
GTK_SCROLL_JUMP,
(gfloat)position/(recipients->rows-1));
// Rounding errors might have positioned us slightly wrong :-/.
oldposition = recipients->focus_row;
if (position < oldposition)
for (int i = oldposition; i != position; --i)
gtk_signal_emit_by_name(GTK_OBJECT(recipients),
"scroll_vertical",
GTK_SCROLL_STEP_BACKWARD, 0);
else if (position > oldposition)
for (int i = oldposition; i != position; ++i)
gtk_signal_emit_by_name(GTK_OBJECT(recipients),
"scroll_vertical",
GTK_SCROLL_STEP_FORWARD, 0);
}
I think the correction of the position could be reduced to half of the
if and without the for loop, but I prefer to play it safe since I am
not sure about the way it is supposed to work.
Good luck,
Anders.
