Hi,

I'm looking and looking and can't find function which get me line
number at some TPoint. There is a lot of similar functions which uses
TPoint but useless for my case.
I'm store some data on each line in Lines.Object property. I want read
this data from line when user click on link (OnClickLink event which
have X and Y params)

Regards

I think you are doing something wrong with your "looking" ;-)
After 30 seconds I've found this

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure T
Form1.SynEdit1MouseMove(Sender:TObject;Shift:TShiftState;X,Y:Integer);
var RC:TPoint;begin RC:=SynEdit1.PixelsToRowColumn(Point(X,Y)); Captio
n:=inttostr(RC.Y);end;

IIRC the X,Y in the OnClickLink event are in lines (and columns)
already, instead of pixels.

So that should be what you need.

Otherwhise
PixelsToRowColumn
PixelsToLogicalPos

They differ in how the return the x coordinate. either as char/grid or
byte offset.
