Hello All,

I seem to be having a problem using the canvas' Polygon method.  When I call
it like:

Canvas->Polygon(clearBlock, 4);

Where clearBlock is an array of 4 points consisting of:
{ { 652, 5 }, { 752, 5 }, { 752, 129 }, { 652, 129 } }

These points definitely form a square, but I get weird and unpredictable
output from polygon.  Changing the order of the points
seems to give me different albeit similarly dissatisfying results.  So I
guess the order matters, but what order is supposed to be used?

Thanks,

-Mike

Hi Michael,

The second (last) parameter to the Polygon() member function should be
the zero-based index of the last point in your array (i.e., it should
specify one less than the total number of point in the clearBlock
array).  Try passing 3 instead of 4.

Best of luck,

If you look up the example in the online help of TCanvas::Polygon() you'll
see the above line expects five points in the clearBlock array.

Type: Canvas->Polygon( clearBlock, 3 );

and it should work...;-))
