Using QSettings with QColor

El3ctroGh0st

Hello everyone,

I am currently trying to get a saveSettings() and loadSettings() function to work in order to save the settings even when the program is closed. However, I am facing a problem with my loadSettings() function...

void Settings::saveSettings()
{
    QSettings setting("textFinder","tFSettings");

    setting.beginGroup("textFinder");
    setting.setValue("colour", this->colour); //QColor
    setting.setValue("language", this->language); //QString
    setting.endGroup();
}

This is the saveSettings() function, and it seems to work without any problems. This is my loadSettings function:

void textFinder::loadSettings()
{
    QSettings setting("textFinder","tFSettings");

    setting.beginGroup("textFinder");
    defaultColour = setting.value("colour", Qt::yellow);
    defaultLanguage = setting.value("language", "English").toString();
    setting.endGroup();
}

However, on attempting to compile the program I get the following error:

C:\Users\Laurenz\Documents\QT\textFinder\textfinder.cpp:131: error: use of deleted function 'QVariant::QVariant(Qt::GlobalColor)

I get what this error means. I suppose that I have to use something similar to .toString(), but I browsed the list of suggestions and nothing popped up that I could use here... Any suggestions?

EDIT: Actually, I think I've fixed it. I've basically just created a QString instead and then used the QColor::setNamedColor() to get the colour. Thanks anyways to everyone who read this!

try:

QColor color=settings.value("colour").value<QColor>();
