[mapguide-internals] RFC15 - Addendum 4

[Chris Claydon]

Will the tooltips in the AJAX viewer be modified to use the new API with
an appropriate bitmask and maxFeatures=1?

Yes. The bitmask will be 5, to indicate that the layers being queried
must be visible and have tooltips, but that we don't care whether or not
they're selectable.

With multiple layers, if you select maxFeatures=1, does it use the layer
draw order to determine which one to query first? 

Yes. 

Once it hits the maxFeatures limit, does it short-circuit and prevent
testing all the other layers?

Yes.

Great!

Few questions:

Will the tooltips in the AJAX viewer be modified to use the new API with
an appropriate bitmask and maxFeatures=1?

With multiple layers, if you select maxFeatures=1, does it use the layer
draw order to determine which one to query first?  

Once it hits the maxFeatures limit, does it short-circuit and prevent
testing all the other layers?

Following Trevor's suggestion, I have updated the RFC to describe the
use of a bitmask value to allow selective filtering of features based on
whether the layer is visible, selectable and/or has tooltips.

Please let me know if you have comments.

Chris.
