Re: [perl-win32-gui-users] Win32-GUI-DC Polygon

[Roode, E. <er...@ba...>]

What??!  You mean you couldn't understand the crystal-clear Win32::GUI
docs?   What's wrong with you?=20

Just kidding.  The Win32::GUI docs are awful.

On that page, [X,Y]+ refers to a set of points (one point for each
vertex of the polygon).  You pass the points as X, Y
coordinates in one long list.  Here:

    $dc->Polygon(10, 10, 10, 200, 200, 200, 10, 10);

This draws a right triangle with its right-angled vertex at (200, 200).
If you like, you can group the arguments:

    $dc->Polygon( (10, 10), (10, 200), (200, 200), (10, 10));

They all get flattened out into one list anyhow.

Perl-Win32-GUI users,

=20

    I'm looking for an example using Win32-GUI-DC, specifically creating
Polygons (or any of the Poly... objects). The format to create a Polygon
objects is:

=20

$DC -> Polygon([X,Y]+)

=20

What is getting passed to the polygon - I don't understand the [X,Y]+
notation?

=20

Thanks,
