How to trap keystrokes in ListIcon gadget?

Basically the same question as http://www.purebasic.fr/english/viewtopic.php?t=29918

but I'm sorry, the answer doesn't compile. PB doesn't know what #WM_KEYDOWN means.

Robert, you must be running an older version of PB in which that constant is not defined. Mine is v5.62 and the value #WM_KEYDOWN = 256 according to the compiler so put that at the top of your code somewhere and PB will then understand it.


#WM_KEYDOWN = 256 : at the very top of your code

@RobertSF
Are you using the demo version of PB?

[Shardik]

#WM_KEYDOWN and #VK_DELETE are constants defined in the Windows API (Application Programming Interface) or more specific Win32 API and are predefined only in PureBasic for Windows. EventwParam() is a deprecated PureBasic function only available in PureBasic for Windows.

So in order to help you we have to know on which OS (Linux, MacOS or Windows) you are currently doing your tests with PB. The demo versions don't support API functions so the demo version of Windows won't work with examples containing API functions.

Thank you, everyone.

Yes, I'm on the demo version, and Shardik's explanation makes sense.
