Working with Tooltips

A tooltip may be used to provide a small amount of information about a vector object. This is generally displayed when the cursor moves over the object. To use a tool tip, first the function L_VecSetObjectTooltip should be called to set the tool tip string. The tool tip can then be displayed by calling L_VecShowObjectTooltip.

To hide a displayed tool tip, such as when the cursor moves off the vector object, the function L_VecHideObjectTooltip should be called.

An object's too ltip can also be changed using the L_VecSetObjectTooltip function. To determine the current tool tip, call the L_VecGetObjectTooltip function. Make the necessary changes to the string and then call L_VecSetObjectTooltip.
