Win32::GUI WM_DISPLAYCHANGE

wirelesslayers has asked for the wisdom of the Perl Monks concerning the following question:

Greetings noble and wise PerlMonks, I am struggling to make a simple receive WM_DISPLAYCHANGE informing my Win32::GUI app that the Windows Screen Resolution has changed, since the results for this question is "Found 0 nodes roughly between 2016-09-15 and 2014-04-11" Is there here any wise PerlMonk who could provide a simple working example of a simple Win32::GUI that detects a WM_DISPLAYCHANGE message and print some info about that change in resolution? Thanks in advance.

Hi, Try using https://metacpan.org/pod/distribution/Win32-GUI/GENERATED/Win32/GUI/Reference/Methods.pod#Hook something like `$main->Hook( WM_DISPLAYCHANGE(), \&onDisplayChange ); sub onDisplayChange { my( $object, $wParam, $lParam, $type, $msgcode) = @_; print "Click handler called!\n"; }` [download]	[reply] [d/l]
