To MapX Developers
There appears to be a small but confusing discrepancy between the on-line
Help and the reality of MapX 4.5.
It concerns the support for on-screen editing, the functionality that allows
the user to move, resize or select-for-delete a feature object with mouse
gestures.
In MapX, two distinct mouse tools called Arrow and Select are defined,
rather than the single Select tool used in MapInfo Pro. The MapX 4.5 Help
say this about Arrow and Select:
Under [MapX User Guide][MapX Tools][Overview of Standard Tools]
Tool Constant Description
Arrow miArrowTool Click on title or annotations.
Also, moves or resizes selected
features in editable layers.
Select miSelectTool Click to select features.
and under [MapX User Guide][[MapX Tools][Object Editing Tools]
... the built-in Arrow tool can be used to move or resize features in the
current selection. To move the selected feature(s), simply click and drag in
the selection. To resize the selected feature(s), click and drag in the edit
handles. To delete the selected feature(s), press the Delete key.
BOTH THESE STATEMENTS CONCERNING THE ARROW TOOL ARE WRONG.
In fact it's not the Arrow tool that allows you to move, resize or delete
Features, it's the Select tool. You can confirm this by reading the sample
VB program "ObjectEditing" provided with MapX 4.5.
Footnote: MapX supports Title and Annotation objects (that are created
programmatically) as well as Feature objects (that come from the Obj column
in a MapInfo spatial database table). It appears that the Arrow tool
allows you to move, resize and set as a delete-target both Title and
Annotation objects but NOT Feature objects. On the other hand the Select
tool allows you to move, resize and set as a delete-target BOTH
Title/Annotation objects and Feature objects.
