| class Alf::IAlfContainerWidget : public Alf::IAlfWidget |
The interface for container widget.
Container widget maintains it's own control group. When a widget control is set to container widget throught the IAlfWidget::setControl() - method the control is automatically appended to the container widget's control group. If the control that is being set to the container widget is already part of another control group it will be removed from the previous control group and appended to the container widget's control group.
