[mapguide-internals] Google Chrome cursor displacement in Ajax viewer

[Gabriele Monfardini]

Hi, this is a Chromium/Chrome bug

https://code.google.com/p/chromium/issues/detail?id=145919
http://code.google.com/p/chromium/issues/detail?id=12578


Since the bug does not appear for standard cursors, a possible
workaround is to use plain crosshair cursor instead of beatiful .cur
cursors whenever "tip" precision is required (IMHO in digitizing and
in measure point precision is required).

For instance, this is how to have standard crosshair in digitizePoint
and measure

function SetMapCursor(strCursor) in file: ajaxmappane.templ

-    else
-    {
-			strCursor = "url('../stdicons/" + strCursor + ".cur'), pointer";
-    }

+    else
+    {
+		//https://code.google.com/p/chromium/issues/detail?id=145919
+		if (chrome && (strCursor == "digitizePoint" || strCursor == "measure"))
+			strCursor = "crosshair";
+		else
+			strCursor = "url('../stdicons/" + strCursor + ".cur'), pointer";
+    }

I've filed ticket 2105 (https://trac.osgeo.org/mapguide/ticket/2105)
