UI Loading Text

[iasdev]

When writing the settings you use ui->StepResolutionText->toPlainText() to the the value.

So ui->StepResolutionText is likely the element you want the loaded value to put into, correct?
In which case you locate the setter function that corresponds to the toPlainText() getter.
Assuming ui->StepResolutionText is of type QTextEdit, that would be setPlainText().

ui->StepResolutionText->setPlainText(settings.value("Resolution").toString());

ui->StepResolutionText->setPlainText(settings.value("Resolution").toString());

To copy to clipboard, switch view to plain text mode

Perfect. Thank you good sir.
