Help - I am lost between read-thru and view face events!
I have a view that works like simple Mapserver client with zoom box, etc. I
made
new version that supports panning, by dragging with mouse. All worked fine
(zooming, panning) until I changed simple loading map image from "load" to
"read-thru/to" (see example bellow). Zoom box worked, but while mapfile loads
it
slowly follows cursor instead that by script logic (that I did not change) it
should
stop. And my map pane no more returning to zero offset after map image loading.
How to not loose control over (mouse) events, when read-thru works?
Or what hapens with feels when read-thru works and how to manage those
proceses?
loadMapImg: func [
mapUrl
/local rezImg
][
if exists? %mapImg.gif [ delete %mapImg.gif ]
either attempt [
rezImg: read-thru/to mapUrl %mapImg.gif
; rezImg: load mapUrl
][
return load %mapImg.gif
; return rezImg
][
return none
]
]
