Java caret position FAQ: How do I get the Java caret position in a JTextComponent, such as a JTextArea or JEditorPane?
Wow, this was a bear to find anything about. Everyone always wants to show you how to use a JPopupMenu with a mouse click, such as a right-mouse click, but nobody ever shows you how to display a JPopupMenu when someone uses a keystroke, or keyboard accelerator.
So, using a little Java mojo, here is how I get the caret position in a JTextComponent (JTextArea, etc.) to display a JPopupMenu near the current caret position:
void edit_PopupMenuMenuItem_actionPerformed(ActionEvent e)
{
// i know that "show" is deprecated, but i could not get this to work
// any other way
Point point = jEditorPane.getCaret().getMagicCaretPosition();
jPopupMenu1.show( jEditorPane,
(int)point.getX(),
(int)point.getY());
jPopupMenu1.requestFocus();
jPopupMenu1.grabFocus();
}
If someone else sees this code, and knows of a better way to do this, please let me know. For now, I'm going with this, because it works pretty well.
