pointer events outside the viewport
- In the SVG code listed bellow, a small circle tracks the location of
the mouse and the mouse coordinates are also shown.
When I embed this code in a html document listed below I observe the
1. When the mouse is in the viewport area, everything works as
expected and the circle tracks the mouse location.
2. When the mouse moves from inside the viewport to the outside, I
stop getting the mousemove events (although I am above the the big
3. If I press the mouse inside the viewport and drag it outside, I
continue to get the mousemove events outside the viewport.
If I don't embed the svg document and view it as an independent
document, I get yet another behavior:
Without pressing the mouse I get mousemove events when the mouse is
outside the viewport and is in the area of large x values or large y
values (x>300 or y>300). If I move to area of negative x or y I stop
getting the events (an area outside the window).
These behaviors seem inconsistant and I wonder what the SVG Standard
says about this?
I personally would like to be able to continue to get the mousemove
event from the outside of the viewport without pressing and dragging
the mouse so, for example, I can hide the circle if the mouse gets
ouside the viewport.
Software details: Windows 98se, Adobe SVG Viewer Ver. 1.0 and IE5.5
or NN4.7 (same behavior).
Any comments would be appreciated.
