saveComponent
public void saveComponent()
displays a save dialog for saving the panel to a file. Fixes a bug with the Swing JFileChooser: if you entered a new filename in the save dialog and press Enter thegetSelectedFile
method returnsnull
instead of the filename.
To solve this annoying behavior we call the save dialog once again s.t. the filename is set. Might look a little bit strange to the user, but no NullPointerException! ;-)- Specified by:
saveComponent
