How can i get the cursor position in a text?(in x,y coordinates)

There is a function you can call, not one of the pubicly documented ones, but you can find it in the source, called GeometryUtils.getHighlightBounds(). You pass in the textFlow, and a start and end position, and it returns an array with the textLine and a bounds rect in coordinates relative to the TextLine, for each line the TextRange crosses over. In your case, that would be just one line since you have just one character. You can translate that into container coordinates by calling textLine.localToGlobal, and back to container coordinates (if that's what you wanted) by calling container.globalToLocal.

Note that this will return the highlight area that you would see if the selection covered the range of text.

Hope this helps,
