Ok cool... but what happens when a new version of mapguide comes and you
install this.. these files will be overwritten.
As you don't know if something is changed in one of these
template-files, you cannot just copy them and replace them back after
the install of the new version... or am I wrong?

Hi..
We can change the tolerance for selecting points as well as showing
tooltips, by making changes in: ajaxmappane.templ which is in
Viewerfiles.
For tooltips:
function RequestHyperLinkData(id, x, y, exec)
{
if(lastMapRcv != mapId) return;
if(isPopupOpen(tbMenu) || isPopupOpen(ctxMenu)) return;
req = CreateRequestHandler();
req.open("POST", webAgent, true);
req.setRequestHeader("Content-Type",
"application/x-www-form-urlencoded");
//x1 = x - 2; x2 = x + 2; commented by farah (original. changed to
show
tooltip)
// y1 = y - 2; y2 = y + 2; commented by farah (original)
x1 = x - 5; x2 = x + 5;
y1 = y - 7; y2 = y + 7;
pt1 = ScreenToMapUnits(x1,y1);
pt2 = ScreenToMapUnits(x2,y2);
geom = MakeWktPolygon(pt1.X, pt1.Y, pt2.X, pt2.Y);
reqParams =
"OPERATION=QUERYMAPFEATURES&VERSION=1.0.0&PERSIST=0&MAPNAME=" +
encodeURIComponent(mapName) + "&SESSION=" + sessionId + "&SEQ=" +
Math.random() + "&LAYERNAMES=" + encodeURIComponent(GetVisLayers()) +
"&GEOMETRY=" + geom + "&SELECTIONVARIANT=INTERSECTS&MAXFEATURES=1";
obj = new HlRequest(id, x, y, req, exec);
req.onreadystatechange = obj.OnHl;
try { req.send(reqParams); } catch(e) {}
}
For point selection:
In the method: ExecuteRectangleTool
else if(tool == 0)
{
if((x2 - x1 <= 2) && (y2 - y1 <= 2))
{
x1 -= 2; y1 -= 2;
// x2 = x1 + 4; y2 = y1 + 4;commented by farah (original)
x2 = x1 + 8; y2 = y1 + 8;
pt1 = ScreenToMapUnits(x1, y1);
pt2 = ScreenToMapUnits(x2, y2);
RequestPointSelection(pt1.X, pt1.Y, pt2.X, pt2.Y,
appending);
}
Regards
Farah

Can you change the tolerance for selecting points? The Select tool
doesn't
always select a point. Any tips for making this tool work better?
Thanks
