( [id://3333]=superdoc: print w/replies, xml ) Need Help??

I tried the VB code, converted to Perl and using Win32::API. (the code isn't the tidiest in the world, I've missed out most of the program):

... use Tk; use Win32::API; # Windows constants my ($OnTop, $NoTop, $Top) = (-1, -2, 0); my ($SWP_NOMOVE, $SWP_NOSIZE) = (2, 1); ... # Create a Win32::API object for SetWindowPos my $SetWindowPos = new Win32::API("user32", "SetWindowPos", [N,N,N,N,N +,N,N], N); ... my $w = new MainWindow; ... # do the 'always on top' bit my $hwnd = $w->frame; # frame returns a hex value as a string, e.g. "0 +x1234" print "$hwnd\n"; $SetWindowPos->Call(hex($hwnd), $OnTop, 0, 0, 0, 0, $SWP_NOMOVE | $SWP +_NOSIZE); MainLoop;

Unfortunately $w->frame returns the Tk MainWindow, not the Win32 window containing it. As a result setting $w->frame 'always on top' doesn't have any effect.

Anyone know how to get an HWND for a window's parent out of Win32? Tk::Wm's $w->wrapper doesn't work either.

Title:
Use:  <p> text here (a paragraph) </p>

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
