Arrowkey works and does not work

[dunbarx]

In an option menu, it is possible to open the menu with the mouse, and then use the arrow keys to navigate among the menuItems.

But no arrowKey message is sent. If you place this into the button script (and also in the card script if you so desire):

Code: Select all

on arrowkey tKey
   put the selectedText of btn 1
   pass arrow key
end arrowkey

Nothing is returned. The arrow keys work, but do not seem to be invoked with an arrowKey message, How can this be?

Hi Craig,
Thanks for this. I discover this feature that could be useful for accessibility.
I tested in IDE 6.7.0 (the more stable version for the needs of my last app)
I have the same results. It seems that if a menu is open the arrowkey message is catched and can not continue along messages path.

I tried :

Code: Select all

on arrowkey pKey -- with option menu open doesn't works
   beep --no beep
   put the menuhistory of btn 1 into tMH
    put the selectedText of btn 1 into tST
   put tMH & cr & tST 
end arrowkey

on returnkey -- with option menu open doesn't works
     beep --no beep
   put the menuhistory of btn 1 into tMH
    put the selectedText of btn 1 into tST
   put tMH & cr & tST
end returnkey

OK.

Seems like the whole family of popups and pulldowns exhibit similar non-behavior. I will run it by QCC if nobody from LC chimes in soon with an explanation, apology or excuse.

ArrowKey isn't sent to buttons, it's sent to cards and fields. This is a design decision, since most buttons don't have field components, so a QCC report should probably be a feature request rather than a bug.

Jacque.

Figures. It was just that since the arrowKey "message" acted on a button, I thought it ought to be sent to that button. So the arrowKey message knows what the "target" is, but bypasses that control?

But if you already knew that, then I will not make a QCC request.

The Dictionary includes arrowkey among the relevant tokens even filtering for button objects.

The Dictionary includes arrowkey among the relevant tokens even filtering for button objects.

In that case, either the engine or the dictionary has a bug.

In 7.0.4, the arrowKey message does not appear to be sent to a card. Setting a breakpoint in the card script, the handler never gets the message. Here is a snippet of code from the card script that worked perfectly in 6.7.1 thru 7.0.3 to move a graphic oval around a card:
