I am going to see if I can attach that to Gnome2::Canvas. In the mean time I
have started to add the ability to remove waypoints. so far I have this
code:
#remove waypoints
if ($event->type eq "button-press" && $event->button == 3){
print "right click\n";
foreach (@drop){
print $_,"\n";
}
foreach (@drop){
my ($x1, $y1, $x2, $y2) = $_->get_bounds;
#print "$x1, $y1, $x2, $y2\n";
if ($event->x >= $x1 && $event->x <= $x2 && $event->y >= $y1 &&
$event->y <= $y2){
print "In Bounds!!\n";
delete $_;
}
}
foreach (@drop){
print $_,"\n";
$_->request_update;
}
}
With this the user can right click over a waypoint and it will be removed.
I'm struggling with this a bit. I want to be able to remove the array
reference that the user has clicked over and redraw the waypoints (at least
I think this is how it should work). How can I remove the array reference?
How can I redraw the waypoints?
