◆ restoreState()

void KisDialogStateSaver::restoreState ( QWidget * parent,
const QString & dialogName,
const QMap< QString, QVariant > & defaults = QMap<QString, QVariant>() )

restoreState restores the state of the dialog

Parameters
parentthe parent at the top of the QObject hierarchy that contains the child widgets
dialogNamethe name for the section under which we will restore the state
defaultscontains default values for widgets. This overrides what is stored in the config file. If there is no value in the config file, and no default specified, the value set for the widget (for instance in the ui file) will be used.
Returns
true if all the widgets could be restored, false if there was a problem
