- Getting the next character in the mainwindow without stopping the program. Currently only INPUT and INPUT$() are supported. Both stop the program and wait.
- Getting the next character typed for some window or widget that has focus. In other words, reading keypresses for objects with handles (ie. #thisWindow)
What I suggested in the forum is a function called inkey$().
The following would read keypresses for the mainwindow:
print inkey$()
or it could be abbreviated to:
print inkey$
To read keypresses for windows or widgets with handles:
print inkey$(#handle)
I'd like to solicit feedback here. Any ideas? Please leave a comment, and thanks!

I would like to see inkey$() trap, rather than watch, keystrokes. Then you could have
while inkey$() <> chr$(13)
'grab keystrokes and process them
end while
As proposed, that's great! The only thing I'd suggest is a keyboard event handler for windows, like trapclose or resizehandler.
Jerry,
I do understand the need for a key trap, but naming it inkey$ would be confusing for people I think.
I would like to be able to read the input from say a text box and if they press Enter, this cause an update to an array or a data file. This can be done right now using a loop with scan in it, but a single line text box will not cause the loop to react when Enter or Tab is pressed.
It has pained me not having inkey$ available in LB on the text screen. I am accustomed to using this function in many different situations (typically the "Hit Any Key" option). I do hope you add it to the text commands.
I have friends who use the mainwin for quick and dirty progs. They use the GETASYNC function to read the keyboard. If Inkey$() would exist than they would never be pushed to use the IDE (and GUI programming)
Just a thought.
