void nux::View::ActivateView ( )

Activate the View. It can process them. The rendering of the View is normal.

Definition at line 474 of file View.cpp.

  {
    _is_view_active = false;
  }

void nux::View::DeactivateView ( )

Activate the View. The view cannot receive events. Its rendering is grayed (NUXTODO).

Definition at line 479 of file View.cpp.

  {
    _is_view_active = true;
  }

Area * nux::View::FindAreaUnderMouse	(	const Point &	mouse_position,
		NuxEventType	event_type
	)		`[protected, virtual]`

Return the area under the mouse pointer.

Returns:: The Area under the mouse pointer.

Reimplemented from nux::InputArea.

Reimplemented in TilesView, nux::BaseWindow, nux::ComboBoxSimple, nux::FloatingWindow, nux::HScrollBar, nux::HSplitter, nux::Matrix4Editor, nux::MenuPage, nux::ScrollView, nux::TabView, nux::TextEntry, nux::VScrollBar, and nux::VSplitter.

Layout * nux::View::GetLayout ( ) [virtual]

Get the default layout of this view.

Returns:: The default layout of this view.

Reimplemented in nux::BaseWindow.

  {
    return m_CompositionLayout;

bool nux::View::IsFullRedraw ( ) const [protected]

Accessed inside ContentDraw () to help determine if some parts needs to be rendered. Do not use it elsewhere.

Returns:: True if Draw () was called before ContentDraw ().

Definition at line 335 of file View.cpp.

  {
    return _full_redraw;
  }

bool nux::View::IsViewActive ( ) const

Returns:: True if the view is active.

void nux::View::QueueDraw ( ) [virtual]

Causes a redraw. The widget parameter _need_redraw is set to true. The widget Draw(), DrawContent() and PostDraw() are called.

Emits the signal OnQueueDraw.
