Detecting clicks on spatial links using Link Clicked: Difference between revisions

Latest revision as of 14:31, 6 March 2009

If you want the Spatial Links in a Panel to respond to mouse clicks, first set the Panel Option "Send Spatial Link Clicks".

This suppresses the normal link information menu.

Thereafter, whenever the modeller or user clicks on a spatial link line a system broadcast called "_Link Clicked" gets sent.

The broadcast includes the following tuple attributes:

The panel screen co-ordinate at which the mouse was clicked.

The ratio along the spatial link line where the user clicked, from near 0 (start of) approaching 1 (end of link)

Object label identifier of the "from" portal for the link.

Object label identifier of the "to" portal for the link.

Indicates which button was clicked,

Left = 1

Right = 2
