Hi,
Based on the tip op Chip (sounds nice😊), I have created a function that can be
used in the "On Column Resize" event:
C_TEXT($listbox;$1)
C_BOOLEAN($mouse_in_listbox;$0)
$listbox:=$1
C_BOOLEAN($mouse_in_listbox)
GET MOUSE($mouseX;$mouseY;$mouseButton)
OBJECT GET COORDINATES(*;$listbox;$l;$t;$r;$b)
If ($mouseX>=$l) & ($mouseX<=$r) & ($mouseY>=$t) & ($mouseY<=$b)
$mouse_in_listbox:=True
Else
$mouse_in_listbox:=False
End if
$0:=$mouse_in_listbox
