Drawing crosshairs

Hey guys,
I got myself stuck again in something maybe not so easy.
I'm trying to create crosshairs in the orthogonal views for my tool-plugin, corresponding to the mouse-position.
In particular I have problems in my "Draw" method, as it seems to be the only place to draw lines into the viewport but only updates as something in the scenes changes: camera, objects, but not the mouseposition.
The mouse position is another problem, as the "MouseInput" method only seems to kick in when one mouse button is clicked.
So while I got this hole process working with clicking and then dragging the mouse, I would really prefer not to click first. In a way this seems so be possible as the internal lighting-tool does something similar, or just selecting polygons or points of mesh results in a highlighting.
Again a short recap what I'm doing:
- checking the mouse position in the MouseInput method (sadly by clicking first), and forcing a redraw by using c4d.DrawViews(c4d.DA_ONLY_ACTIVE_VIEW|c4d.DA_NO_THREAD|c4d.DA_NO_ANIMATION)
- drawing some lines in the viewport according to the retrieved mouse position in the Draw method
Maybe there is an easier or more logical way someone could explain to me.
Thanx

Maybe you could use GetCursorInfo() which is called when the mouse is moved over the viewport and call DrawViews there?

I honestly don't know why I overlooked that method.
Thanks for the tip, works perfectly
