Why have you changed from FScreenIsRectangleOnScreen() to IsRectangleOnThisPage()?

As otherwise the defined IconBox of the user does not match but that of the global_icon_box_ptr

    while(do_all_iconboxes(t, &icon_boxes_ptr))
    {
      struct monitor *m;
fprintf(stderr, "FFFF: %s %d\n", icon_boxes_ptr->IconScreen, loc_ok);
      if (loc_ok == True)

leads to

loaded [0]: /suse/werner/.fvwm/config
FFFF: DVI-1 0
FFFF: (null) 0

on stderr output of fvwm3 (here with a not set global_icon_box_ptr->IconScreen)

So?

My point is that this is an entirely different function call you're changing. Why?

What is your proposal to make the users IconBox win here. Using NULL for fscreen_scr_arg *arg in FScreenIsRectangleOnScreen() does not help

What I'm asking, is why you changed from FScreenIsRectangleOnScreen() to IsRectangleOnThisPage() -- it's a completely different function.

We're going round in circles, @bitstreamout

What I'm saying about FScreenIsRectangleOnScreen() is it's only used in two places.

Rather than write all this additional crap in icons.c, we should change FScreenIsRectangleOnScreen()'s implementation. We already have both "rectangles" to compare, so we should stop it from looking up monitors, etc., and just pass the relevant information in.

As a consequence ef doing this, we will need to update conditionals.c as well.

Would you prefer if I did this?

Indeed before I do the next crap ;)

Maybe it is enough to use FSCREEN_GLOBAL with FScreenIsRectangleOnScreen() as DVI-1 has an y offset of 1920 and the global screen has twice the size aka 3840

Why add do_free_screen here?

Simply to be sure that the static string is not freed ... even it free_icon_boxes() will currently not reach this.

Is an unnecessary addition.

How to resolve the NULL for the IconScreen of the last IconBox seen from do_all_iconboxes() in the loop?
