Instance Method Details

- (nil) contextMenuEvent(event)

Override of Qt::Widget#contextMenuEvent

If the current document contains syntax errors, it displays a menu listing them. Each action in the menu moves the cursor in the editor view to display to the line and column of the corresponding error.

If the current document doesn’t contain syntax errors, the menu will only contain an entry with text Syntax OK which does nothing when activated.

Returns:

  • (nil)
