You can do this on Windows with an ooDialog dialog, but I don't think
it is possible in a command line program.
Plus it will only capture the key press when the dialog has the focus.
Probably not what you want. But, here is a working example:
/* Dialog that captures the Control key keypress event. */
dlg = .ControlKey~new
if dlg~initCode = 0 then do
dlg~createCenter(170, 90, "Show Control Key Event", -
"VISIBLE MAXIMIZEBOX MINIMIZEBOX")
dlg~execute("SHOWTOP", IDI_DLG_OOREXX)
dlg~deinstall
end
-- End of entry point.
::requires "OODWin32.cls"
::requires "WinSystm.cls"
::class 'ControlKey' subclass UserDialog -
inherit AdvancedControls VirtualKeyCodes
::constant CtrlKey 17
::method defineDialog
self~addButton(IDOK, 130, 70, 35, 15, "Quit")
::method initDialog
self~connectKeyPress(onCtrl, self~CtrlKey)
::method onCtrl
use arg key, shift, control, alt, info
say 'Key press:' key 'shift?' shift 'control?' control || -
' alt?' alt 'extra info:' info
Here's some output:
C:\work.ooRexx>captureCtrlKey.rex
Key press: 17 shift? 0 control? 1 alt? 0 extra info: numOn capsOff
rControl scrollOff
Key press: 17 shift? 0 control? 1 alt? 0 extra info: numOn capsOff
lControl scrollOff
C:\work.ooRexx>
By the way, Ven if you're reading this - it is also an example of
providing minimize and maximize buttons.
