I'm developing leader dots for TLF engine (see: https://support.office.com/en-us/article/Show-dots-or-leaders-between-tabs-c80b62d0-2244-4078-95bd-8c82f91440ba?ui=en-US&rs=en-US&ad=US)
The InsertTextOperation requires the SelectionState parameter (the location in the textFlow to insert a string.
I would to insert a dote " . " at the end of the current cursor line.
I can get the current line (TextFlowLine and from that, the current TextLine).
I can also get the current cursor position from the begining of the line but I can't get the current position from the very begining of the textFlow in the other words what I need is the cursor position of the end of the current line.
If someone could point me the right direction, would me a major help.
PS: After I get this working well, I will donate the final source to Apache Flex.
