Event "New polygon created"

[esrispy]

How can you fire a dialog after digitizing a new polygon?

After a double click or snapped to at the start node so a new polygon
is created i want to prompt the user with a dialog "Select Type of
surface"

[Spencer Simpson]

You create your own custom tool that uses DrawMode DM_CUSTOM_POLYGON. You
then call CommandInfo (CMD_INFO_CUSTOM_OBJ) in the tool's handler procedure
to get the object that was drawn, then prompt for the attributes you want to
prompt for. If the user clicks OK on the dialog, the tool handler routine
then has to insert the new record.

For a little more clarity I suppose I should say:

-1. You create your own custom tool that uses DrawMode DM_CUSTOM_POLYGON.

-2. The user selects your polygon-drawing tool, not MapInfo's built-in one
(you'll have to hide it), and draws a polygon. This invokes the tool
handler procedure you wrote.

-3. Your tool handler procedure:
--a. calls CommandInfo (CMD_INFO_CUSTOM_OBJ) to get the object that was
drawn
--b. displays a dialog you created to prompt for the attributes you want.
--c. The user fills in the requested information (or not) and clicks OK or
Cancel. This returns control to your tool handler procedure.
--d. If the user clicks OK on the dialog, the tool handler routine
then has to insert the new record along with the new object.

Esrispy,
there is code included in this app that does similar to what you want and you can hack it around...a lot of the app you probably wont need, but it was designed to be a generic-tool-for-preset-objstyles-and-data capture and it covers the basics of capture/populate/content predefinition and content transfer..its also as easy as it gets (in case your users are not carto/gis folk)

..health warning..it has a real doh! of a bug in it (look for a brit nat grig coordsys clause that shouldnt be there...take it out and the app will work with any projection..)
