Hi,

I'm trying to get the (x,y) coordinates of a user click on a jdrawview
object, but I get huge numbers like x=1118832016 and y=1148645732, so
I must definitely be doing something wrong.
I am reading the X and Y variables passed to the onClick event.
Can anyone please shed some light on this?
Thank you very much.

Hi, The code below works fine for me.
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
TAndroidModule1.jDrawingView1TouchDown(Sender: TObject;  countXY:
integer; X: array of single; Y: array of single;  flingGesture:
TFlingGesture; pinchZoomScaleState: TPinchZoomScaleState;  zoomScale:
single);begin  ShowMessage(floattostr(X[0])+','+floattostr(Y[0]));end;

made 
Thank you very much!
