Okay, I've figured this one out and I thought I'd let anyone else who is
interested know how. Stephen Knott put me on the right track with an idea
he had, and I've developed it from there. What I do is put all the ALT
keypresses into the first field of a table and all the extended characters
into the second field (called "Extended character"). Then if the user
enters a character with the ALT key down, a TCursor searches for the key
pressed and copies the extended character in the second field onto the
clipboard, and then the character is pasted into the active field. This
avoids using sendKeys() altogether and further allows the user to alter
the ALT-key list by editing the table. Here is the code, placed in the
keyChar() method of the form:
method keyChar(var eventInfo KeyEvent)
if eventInfo.isPreFilter() then
;// This code executes for each object on the form
if eventInfo.isAltKeyDown() then
sKeyChar = lower(eventInfo.vChar()) ; char() doesn't work if ALT key is down
if eventInfo.isShiftKeyDown() then ; if SHIFT key is down, make character upper case
sKeyChar = upper(sKeyChar)
if tcExtChars.qLocate(sKeyChar) then
sKeyChar = tcExtChars."Extended character"
;// This code executes only for the form
