Saving UI components to file

kprog96

This is a theoretical application that I am trying to prototype.

Let's assume this application already has the capability to let an user create their own assortment of QWidgets in a QGridLayout. What I would also like this application to do is save the QGridLayout and its contents to a file so the user could load that file and their QGridLayout to a window.

Does QT have the power to save Layouts to a file?
If not, can QWidgets be saved to a file?

I have successfully been able to use QDataStream to stream my own structs into a file by overloading the << and >> operators. I did attempt the same thing by trying to overload those operators for QGridLayout and QWidget but was unsuccessful in doing so.

Any input would be much appreciated!

Note: The QT version does not matter to me. The main question is if QT (any version) has the capability to perform such actions. Thank you!

Not by default. You can save QSettings and store properties like geometry and other things.
If you have custom widgets in your layout, you need to develop your own strategy (save a struct with your information to recreate the layout, for example)

You could save the state of your widgets (slider positions, values etc) but not the widget itself

You can not save 'the ui' - you can only save the content of the widgets - e.g. a QString for a QLineEdit. But you have to do it by your own.

Hi,

One thing you might want to explore is QAbstractFormBuilder.
