public virtual void OnCaretMoved(
	CodeWindowManager mgr,
	IVsTextView textView,
	int line,
	int col
)

Parameters

mgr
Type: Microsoft.VisualStudio.Package.CodeWindowManager

[in] The CodeWindowManager object controlling the code window that the caret moved in.

textView
Type: Microsoft.VisualStudio.TextManager.Interop.IVsTextView

line

col

If you want to do anything special when the caret is moved, you must derive a class from the LanguageService class and implement this method. Be sure to call the base class version of this method either before or after your specific needs.

The base method calls the internal TypeAndMemberDropdownBars.SynchronizeDropdowns method if a drop-down bar has been added to the text view. TypeAndMemberDropdownBars.SynchronizeDropdowns calls the virtual method, OnSynchronizeDropdowns, and then refreshes the combo-boxes.
