[Iup-users] Problem with the GTK dropdown list.

[Paul G. <aq...@gm...>]

Hi,

I'm using IUP with Lua on a project at the moment, and discovered a strange
problem which I think I've tracked down the solution to.

When using an IupList control, with DROPDOWN="YES", and populated with a
single value, if I do...

mylistctrl.value = 1

to programmatically select the first (and only) entry, it fails, leaving the
selection empty. I tracked this down to line 352 in the file
src/gtk/iupgtk_list.c (this is on a copy of the source from version 3.0rc3.
The line checks that the specified value is >0 and < the number of values in
the list, but doesn't take into account that the GTK indices are 0 based,
but the IUP indices are 1 based. The code at line 354 correctly takes this
into account, so it's possible to programmatically select any but the last
entry in the list.


As an aside, I'm really enjoying working with this toolkit, much moreso than
many others I've had experience with, especially the Lua binding,
congratulations to all involved on a nice, clean interface.

Cheers


Paul
