In this episode of the Notepad App w/ Python & Qt series, I demonstrated the implementation of the unsaved dialog.
When the user attempts to open or close a file, or close the entire application, these actions will potentially cause the loss of progress. It is therefore necessary to have an unsaved dialog to warn the user about their progress.
The implementation consists of two parts, the saved status and the dialog. The saved status indicates if the current progress has been saved. If not, an unsaved dialog will show up when the user attempts to perform the "dangerous" actions.
This episode includes the instantiation of a new component within the QML context, as well as the property feature in QML.
This series is created as an example of building a GUI application using Python, as well as building a desktop application which will work on Linux and Windows. Follow this series and you will learn how to make a GUI app using Python and the Qt framework.
