Detailed Description

This is an interface for widgets which act as a container for multiple children, like UIBox or UILayered.

Member Function Documentation

virtual void AlgAudio::UIContainerMultiple::Clear ( )

pure virtual

Implemented in AlgAudio::CanvasView, AlgAudio::UIBox, AlgAudio::UIList, and AlgAudio::UILayered.

virtual Point2D AlgAudio::UIContainerMultiple::GetChildPos ( std::shared_ptr< UIWidget >  ) const

pure virtual

Implemented in AlgAudio::CanvasView, AlgAudio::UIBox, and AlgAudio::UILayered.

virtual void AlgAudio::UIContainerMultiple::OnChildFocusRequested ( std::shared_ptr< UIWidget >  )

inlineoverridevirtual

This method gets called when a child widget tries to catch focus. Multiple container widgets should react on it by remembering which widget is the focused one, and passing keyboard events to it. Single container widgets can ignore this signal, as they have no choice as to whom they shall pass such events to.

Argument: the child that is requesting focus.

Reimplemented from AlgAudio::UIWidget.

virtual bool AlgAudio::UIContainerMultiple::OnChildFocusTested ( std::shared_ptr< const UIWidget >  )

inlineoverridevirtual

This method is called by a child when it has to ask the parent whether it is the focused child. This is necessary for performing IsFocused() test. Containers should override this method.

Reimplemented from AlgAudio::UIWidget.

virtual void AlgAudio::UIContainerMultiple::OnFocusChanged ( bool  )

inlineoverridevirtual

This method is called when the widget focus state has changed. The only param states whether this widget has now the focus

Reimplemented from AlgAudio::UIWidget.

virtual void AlgAudio::UIContainerMultiple::OnKeyboard ( KeyData  k )

inlineoverridevirtual

Reimplemented from AlgAudio::UIWidget.

Reimplemented in AlgAudio::CanvasView.

virtual void AlgAudio::UIContainerMultiple::RequestFocus ( )

inlineoverridevirtual

This method is called by the widget when it wishes to grab focus, for example a text entry field should call this method when it's clicked.

Reimplemented from AlgAudio::UIWidget.
