How do I locate the cursor position in a Java textarea where the text is held in a StringBuffer? I am trying to implement the backspace function in a text editor. The API lists how to set data. I need to get the cursor position, to know at which character position the cursor is, not the onscreen global coordinates of the cursor.
Any assistance is sincerely appreciated.
You have to write
KeyListenersfor keypress events in theTextAreaand keep a virtual cursor of where you are in theTextArea. Then map that offset into yourStringBuffer, there is no magic way to do it.
