How do I carry out an action, when i am just hovering over the target object? Lets say i want to move a piece of pie chart a tad away from the center when hovering over it. It should return to its original position when the cursor is somewhere else. I could not find any solution by fiddling with nodes nor in the forum. Any suggestions ?
I am asking only for the mouse over part, the application just serves as an example. I either shift the coordinate system or make a cartesian/polar conversion. But how do i detect that the mouse cursor hovers over the object?
