Return empty brush/pen/font via API rather than the weird default one...

Return empty brush/pen/font via API rather than the weird default one Previously a non-initialized QPen()/QBrush()/QFont() was returned if axis/series hadn't been added to a chart yet and therefore had not been themed yet. To keep API somewhat consistent with old behavior, return non-initialized QPen()/QBrush()/QFont() instead of the weird default one in these cases. The new behavior is slightly different in that it is no longer possible to restore themed behavior by setting pen/brush/font to non-initialized one, but since there is no way to differentiate e.g. legitimate Qt::black pen from non-initialized pen, we can no longer support this behavior.

        This file was generated by the Qt Quick Application wizard of Qt Creator.

        QmlApplicationViewer is a convenience class containing mobile device specific

        code such as screen orientation handling. Also QML paths and debugging are

        handled here.

        It is recommended not to modify this file, since newer versions of Qt Creator

        may offer an updated version of it.
