QSplitter::restoreState() not working

[PeterThePuter]

Hey all!

I have a quick question: When using a splitter, I would like it to restore itself to the position it was at last time the application closed. I have been able to restore the main window's geometry just fine, but when attempting to restore a splitter, it doesn't work.

When the application starts:

QSettings settings;
 
    // Main window settings
    settings.beginGroup("mainWindow");
    restoreGeometry(settings.value("geometry").toByteArray());
    splitter->restoreState(settings.value("splitterState").toByteArray());
    settings.endGroup();

QSettings settings;

    // Main window settings
    settings.beginGroup("mainWindow");
    restoreGeometry(settings.value("geometry").toByteArray());
    splitter->restoreState(settings.value("splitterState").toByteArray());
    settings.endGroup();

To copy to clipboard, switch view to plain text mode 

When a close event is called:

QSettings settings;
 
    // Main window settings
    settings.beginGroup("mainWindow");
    settings.setValue("geometry", saveGeometry());
    settings.setValue("splitterState", splitter->saveState());
    settings.endGroup();

QSettings settings;

    // Main window settings
    settings.beginGroup("mainWindow");
    settings.setValue("geometry", saveGeometry());
    settings.setValue("splitterState", splitter->saveState());
    settings.endGroup();

To copy to clipboard, switch view to plain text mode 

The splitter always starts in the middle, regardless of where I leave it at close.

Any help?
