We've found using comboboxes and certain other GUI controls aren't
touchscreen friendly at all. We have a generic graphical 'quick
selection' box-- the user clicks something, and we show a modal box
with the options, and they pick which one they want. If there's more
options than can fit on the large buttons(say, 6 of them), the code is
smart enough to draw and handle buttons that will scroll the options
available. We invoke it something like this:
o = createobject("quickselection", "pick your item")
o.additem("red", RGB(255, 0, 0)
o.additem("green", RGB(0, 255, 0)
o.additem("blue", RGB(0, 0, 255)
o.additem("cancel", -1)
o.show()
if -1 == o.evalue then
* cancelled
else
do case
case rgb(255,0,0) == o.eValue
* Red
case rgb(0,255,0) == o.eValue
* Green
case rgb(0,0,255) == o.eValue
* Blue
end case
endif
Something like that-- using a variant for each item lets us avoid any
conversions, etc.
Not an answer to your question, but possibly a more user-friendly
solution for your GUI design if you have the freedom to change it.
