Trinione | Maybe I am just not seeing it. But, how can I draw a horizontal line? Or a square? A circle?

Chris Holland SEC Solutions Ltd. Team Elevate | Hi,
If you use a TPaint component you can use things like LineTo(X,Y) etc. There is an Paint example project that ships with EWB2 that demonstrates this.

Drop a TPaint on the form, and the rest should give you the right clues. Basically you draw on its canvas. Paint1: TPaint; m_xBlah.DrawToCanvas(paint1.Canvas, lblTest.Font); procedure TBlah.DrawToCanvas(xCanvas : TCanvasElement; xFont : TFont); begin xCanvas.FillColor := clWhite; xCanvas.FillRect(0, 0, xCanvas.Width, xCanvas.Height); xCanvas.MoveTo(ptStart.X, ptStart.Y); xCanvas.LineTo(ptEnd.X, ptEnd.Y); xCanvas.Stroke; end; -- Matthew Jones |
