Press a focused button in Maxscript

I was wanting to press a focused button in Maxscript using standard buttons if possible. I think this would be easily done using a .NET button but I was just curious if it was possible to press the focused button using the standard MaxScript button control.

Here's the code I have which focuses the button but the the button event handler does work even though the button is focused. I assume it's because its a mouse click only event.

try destroyDialog testRol catch()
rollout testRol "testRol" (

  button btn_yes "Y̲es" width:120 across:2
  button btn_no "N̲o" width:120

  on btn_yes pressed do destroyDialog testRol
  on btn_no pressed do print "Oh no.."

  on testRol open do setFocus btn_yes

  )
createDialog testRol 525 45
OK
Solution

  • If you want to press mxs button, use its handle:

    on testRol open do UIAccessor.PressButton btn_yes.hWnd[1]

    If you want to press the focused button, get its handle and use it the same way:

    on testRol open do
(
    local user32 = (python.import "ctypes").windll.user32
    setFocus btn_yes
    UIAccessor.PressButton (user32.GetFocus())
)
