This application, built in VB using MapObjects, allows the user
to zoom in, zoom out and pan using only the mouse. The pan is
a dynamic pan just push the mouse in the direction you would
like to pan.
abel Tool Sample
Requires: Visual Basic 6 and MapObjects 2.x
Data: redlands.shp (Redlands sample data set from MO 2.x)
Interactive Labeling Tool
If the check box is checked, then the mouse down location will search for the closest line, and label it with the street name. If the check box is not checked, then the mouse down will turn into a pan/zoom tool.
There is a slider bar to control the search tolerance in screen pixels for the labeling.
Writing an Input Module
The sample module introduced here is called idiom (Input Device for Intercepting Output of Mice), The sample module registers itself with the USB kernel subsystem as a mouse driver and with the input management subsystem as a keyboard driver. idiom translates mouse movement events into keyboard input events: it reports arrow events to the input system according to how the physical mouse is moved.
