QColor vector in QSettings

[Mint87]

Hi everyone!

I want to save std::vector<QColor> ColorVector in QSettings. Tried a simple way:

QSettings settings;
	settings.beginGroup("ColorConfigurationWidget");
	settings.setValue("currentColorVector", ColorVector);
	settings.endGroup();

QSettings settings;
	settings.beginGroup("ColorConfigurationWidget");
	settings.setValue("currentColorVector", ColorVector);
	settings.endGroup();

To copy to clipboard, switch view to plain text mode 

But QSettings doesn't work with vectors, I guess.. The size of ColorVector is not fixed.
Does anyone know how to handle this problem?

Thank you!

You should user Array not Group, see example

std::vector<QColor> ColorVector;
QSettings settings;
 
settings.beginWriteArray("ColorVector");
for(unsigned int i = 0; i < ColorVector.size(); i++)
{
    settings.setArrayIndex(i);
    settings.setValue("QColor", ColorVector.at(i));
}
settings.endArray();
settings.sync();

std::vector<QColor> ColorVector;
QSettings settings;

settings.beginWriteArray("ColorVector");
for(unsigned int i = 0; i < ColorVector.size(); i++)
{
    settings.setArrayIndex(i);
    settings.setValue("QColor", ColorVector.at(i));
}
settings.endArray();
settings.sync();

Thanks a lot, Santosh!

Since QColor can fit into QVariant, you should (not sure, didn't test) be able to just use QVariantList for your color settings and save the list directly:

QSettings settings;
QVariantList colorList = myColorList();
settings.setValue("currentColorVector", colorList);

QSettings settings;
QVariantList colorList = myColorList();
settings.setValue("currentColorVector", colorList);
