Create Round Edges in form, a Bug..... ?2004-06-02 02:03:36 AM cppbuilder74 Hi all, I'm trying as part of my application to create form with round edges, for doing that i'm using the folowing method, i post here only part of the full code - TPoint P[30]; int i = 0; // Upper left Corner // = = = = = = = = = = P[i].x = 0; P[i++].y = 5; P[i].x = 1; P[i++].y = 4; P[i].x = 1; P[i++].y = 3; P[i].x = 2; P[i++].y = 2; P[i].x = 3; P[i++].y = 1; P[i].x = 4; P[i++].y = 1; P[i].x = 5; P[i++].y = 0; . . . . . // Lower left Corner // = = = = = = = = = = P[i].x = 5; P[i++].y = Height - 0; P[i].x = 0; P[i++].y = Height - 5; SetWindowRgn( Handle, CreatePolygonRgn( P, i, WINDING ), true ); -- -- -- -- -- -- -- The problem is that it seems like the line that i'm trying to draw for the corners in not going exactly as the X & Y positions that i set in the 'P[]' array, i checked it in the windows paint under the largest zooming that let me see every pixel and pixel, and as i checked it i saw some points that where different from the positions that i set in the array, for example if i set - P[7].x = 5; P[7].y = 8; P[8].x = 7; P[8].y = 12; then when i'm looking under windows paint i see that the line was actually drawn between the spots - ( 5, 8 ) - ( 7, 11 ); // This is wrong it should be 12 not 11!! I didn't check this exactly numbers, it was only an example that i hope that will let you understand what i'm talking about. So, how can it be? why does it happens? what should it do? Thanks, Ramy |
