Hi all.
While developing my application I was surprised that tooltip text I've
set for my entry primary icon was never shown. To discover the problem
I've connected to default callback gtk_entry_query_tooltip() in
gtkentry.c.
While debugging I found that gtk_entry_get_icon_at_pos() always returned
-1. The problem is that get_frame_size() function returns entry
allocation x and y those are relative to container where entry is packed
in. But x and y that came in query_tooltip callback as parameters are
relative to entry widget. So, if we do not adjust x and y by subtraction
frame_x and frame_y everything should work right. Because after we
compare x and y to icon allocation where cooardinates also relative to
entry widget.
/**
* gtk_entry_get_icon_at_pos:
* @entry: a #GtkEntry
* @x: the x coordinate of the position to find
* @y: the y coordinate of the position to find
*
* Finds the icon at the given position and return its index.
* If @x, @y doesn't lie inside an icon, -1 is returned.
* This function is intended for use in a #GtkWidget::query-tooltip
* signal handler.
*
* Returns: the index of the icon at the given position, or -1
*
* Since: 2.16
*/
gint
gtk_entry_get_icon_at_pos (GtkEntry *entry,
gint x,
gint y)
{
GtkAllocation primary;
GtkAllocation secondary;
gint frame_x, frame_y;
g_return_val_if_fail (GTK_IS_ENTRY (entry), -1);
/* this commented code is not needed to show icon
* tooltip properly
*
* get_frame_size (entry, &frame_x, &frame_y, NULL, NULL);
* x -= frame_x;
* y -= frame_y;
*/
get_icon_allocations (entry, &primary, &secondary);
if (primary.x <= x && x < primary.x + primary.width &&
primary.y <= y && y < primary.y + primary.height)
return GTK_ENTRY_ICON_PRIMARY;
if (secondary.x <= x && x < secondary.x + secondary.width &&
secondary.y <= y && y < secondary.y + secondary.height)
return GTK_ENTRY_ICON_SECONDARY;
return -1;
}
