Exit GUI Plugin
Sorry if this is a stupid question: But how do I exit a GUI plugin without starting the main dialog if an error occurs during initialization?
Example: If the user has not selected a book, I print the following message in the __init__ method of class MyGuiPluginDialog(QDialog): Code:
d = error_dialog(self.gui, 'MyGuiPlugin', _('No book selected!')) d.exec() But how do I stop executing the plugin at this point? "return" shows the error dialog again, after "OK" the main dialog of the plugin is shown. "sys.exit()" closes Calibre itself. |

You perform the check before creating your dialog, and return from whatever function you are creating the dialog in.
