 Posted: Thu Oct 05, 2006 5:18 am Post subject: Dual Head Monitor Control |
 |
|
I want to be able to draw on a particular form and have that form
appear on a second monitor.
The second monitor will actually be a projector.
Monitor 1: The user clicks on a specific button.
Monitor 2: A red spot appears at a specific location, depending on
which button was pressed.
Drawing the spots is no problem, it's the monitor control I don't know
anything about.
I'm using Delphi 6 Pro and a Matrox Dual Head video card.
This will form part of some tests in an Optometry lab.
Any advice would be appreciated.
Thanks, |

Look at the global variable Screen.Monitors[] property. Your 2nd monitor
should be in there, and contain the coordinates of where you have to place
your form on the desktop (TMonitor.Left/Top/Width/Height).
Your desktop is just one big virtual screen containing both screens.

Hi,
how do you drive the spot? do you paint it in a form or directly to the
screen?
