Re: [OpenMap Users] VMAP DATA display troubles

Hi Vincenzo (and Darol),

OpenMap 4.6.3 included some updates to the OMGraphic classes and VPF
component classes that allow for the display of those attributes as
labels, tooltips or information line entries in other widgets.

These attributes can be enabled with VPFLayer property settings, namely:


The attribute display can be label, tooltip, information line

The attribute label can best be found by running the layer and
bringing up the palette, which will provide an option menu with
available attributes, with the codes in ().

It turns out that there was a bug in the code for the
FeatureDrawingAttributes class, I'll be checking the change into the
codebase soon, and I've included the updated file in this email.

Hope this helps,
