control an object with mouse in display scene

[morteza]

Hello my friends.

Can I control an object with mouse in display scene? I want to input the position of a ball to a control loop with mouse.please help me.

You can draw a ball in a picture control and then use mouse events to manipulate the redrawing of the ball to simulate dragging. Attached is a VI that updates the coordinates indicator when the mouse button is down inside the picture control. This is half the problem.

Hello mike,

Thank you for your help,

But I can,t take an output from it.

How can I take an output from while loop.

You don't.

Your whole interface gets built into the event structure. For example, the case in the Mouse Move event that contains the coordinates indicator should incorporate the code to move your ball to the new location. The code for initializing the display goes outside the loop and gets executed before the loop starts. For other controls that your application requires, add event cases to handle them as needed.
