[Qt-interest] Storing Qt properties to file

[Schimkowitsch Robert]

Hi,

I want to be able to write the properties of my object to file in a
locale-independent way, and be able to restore the object using that
stored information later on.

Before I start reinventing the wheel, I'd like to know whether something
like this already exists (I couldn't find it, but then again Qt has
grown big).

My plan includes the following steps. If you happen to know existing
classes or samples that cover those steps, please let me know!

1) Read and write QVariant: Handling of basic data types (float is a bit
tricky, unicode strings might be)
2) Write a reader and writer that writes all Q_PROPERTIES of an object
to an XML file, and reads them again, restoring the object properties.
By using propertyOffset() of QMetaObject, I should be able to filter out
base class properties that should not be saved and restored.
3) Define the needed properties in my objects, and call the
reader/writer

Kind regards

Robert Schimkowitsch
