Dynamically registering events to track mouse moves
Print
Suppose you wanted to create a VI in which the user is able to move an image around the front panel. For this, you need to track how the user moves the mouse around the front panel.
Attached you will find 2 VIs that perform this same task, but one is a lot more efficient because it uses dynamic events to set the VI to look for mouse moves only when it needs to, only when the user wants to move the image.
Look at the while loop iteration counter to see how in the VI that does not use dynamic events, events are fired continously when the mouse is being moved.
