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?

Hi PeterThePuter,

I also tested this and noticed that you can correctly save into QSettings object only if you define the organizationName on the QApplication object.
Something like this:

QApplication a(argc, argv);
a.setOrganizationName("TestSplitter");

QApplication a(argc, argv);
a.setOrganizationName("TestSplitter");

To copy to clipboard, switch view to plain text mode

Hello,

I have exactly the same issue. The issue is not in saving the
QSplitter state. I am sure that the data is well stored and read
from my settings file.

The issue is that, in some case, the QSplitter is not restored.

PeterThePuter, did you solve that issue?

Thanks
