Allows to define size and position for a custom caret.
TRVMeasureCustomCaretEvent = procedure (Sender: TCustomRichViewEdit;
var Rect: TRect) of object;
property OnMeasureCustomCaret: TRVMeasureCustomCaretEvent;
(introduced in version 10)
A custom caret is drawn if CustomCaretInterval>0.
This event is called before each call to OnDrawCustomCaret. It allows to set your own size and position for the caret. The default size and position are the same as of the default system caret. The editor stores background under the Rect, it will be restored after the call to OnDrawCustomCaret.
If the global variable RichViewEditCustomCaretSize = True, this even is called for the standard caret as well. If RichViewEditCaretPosition <> rvhcpRight, the editor adjusts the position of the caret after calling this event.
