Detailed Description

A widget that takes std::functions for its event handlers, avoiding the need to subclass Widget for basic "heartbeat" functions.

Member Function Documentation

◆ bounds()

virtual Rect2D G3D::Widget::bounds ( ) const

inlineoverridevirtualinherited

Inherited from Surface2D.

Implements G3D::Surface2D.

Reimplemented in G3D::GuiWindow, G3D::GConsole, and G3D::FullScreenWidget.

◆ create()

static shared_ptr<CallbackWidget> G3D::CallbackWidget::create ( )

inlinestatic

◆ createShared()

template<class T , class ... ArgTypes>

static shared_ptr<T> G3D::ReferenceCountedObject::createShared ( ArgTypes &&... args )

inlinestaticprotectedinherited

Like std::make_shared, but works for protected constructors.

Call as createShared<myclass>.

◆ depth()

virtual float G3D::Widget::depth ( ) const

inlineoverridevirtualinherited

Inherited from Surface2D.

Controls the depth of objects when rendering. Subclasses may override this but it can interfere with the normal handling of rendering and event delivery. depth = 0 is usually the "top" widget and depth = 1 is usually the "bottom" widget.

Implements G3D::Surface2D.

Reimplemented in G3D::GuiWindow, G3D::GConsole, and G3D::FullScreenWidget.

◆ fireEvent()

virtual void G3D::Widget::fireEvent ( const GEvent & event )

virtualinherited

Fire an event on the containing window.

Reimplemented in G3D::WidgetManager.

◆ manager()

WidgetManager* G3D::Widget::manager ( ) const

inlineinherited

◆ onAfterEvents()

virtual void G3D::Widget::onAfterEvents ( )

inlinevirtualinherited

Invoked after all onEvent handlers for the current frame and before onUserInput for any other Widget.

Reimplemented in G3D::WidgetManager, and G3D::GameController.

◆ onAI()

virtual void G3D::Widget::onAI ( )

inlinevirtualinherited

Reimplemented in G3D::GuiWindow, G3D::WidgetManager, G3D::ThirdPersonManipulator, G3D::GConsole, G3D::FirstPersonManipulator, G3D::VideoRecordDialog, and G3D::UprightSplineManipulator.

◆ onBeforeGraphics()

virtual void G3D::CallbackWidget::onBeforeGraphics ( )

inlineoverridevirtual

Invoked by WidgetManager immediately before GApp::onGraphics runs.

Reimplemented from G3D::Widget.

◆ onEvent()

virtual bool G3D::Widget::onEvent ( const GEvent & event )

inlinevirtualinherited

Returning true consumes the event and prevents other GModules from seeing it.

Motion events (GEventType::MOUSEMOTION, GEventType::JOYHATMOTION, JGEventType::OYBALLMOTION, and GEventType::JOYAXISMOTION) cannot be cancelled.

Reimplemented in G3D::GuiWindow, G3D::WidgetManager, G3D::ThirdPersonManipulator, G3D::GConsole, G3D::Discovery::Client, G3D::SceneEditorWindow, G3D::FirstPersonManipulator, G3D::VideoRecordDialog, G3D::UprightSplineManipulator, G3D::CameraControlWindow, G3D::GuiMenu, G3D::ControlPointEditor, G3D::DeveloperWindow, and G3D::ArticulatedModelSpecificationEditorDialog.

◆ onNetwork()

virtual void G3D::Widget::onNetwork ( )

inlinevirtualinherited

Reimplemented in G3D::GuiWindow, G3D::WidgetManager, G3D::ThirdPersonManipulator, G3D::Discovery::Server, G3D::GConsole, G3D::FirstPersonManipulator, G3D::Discovery::Client, and G3D::UprightSplineManipulator.

◆ onPose()

virtual void G3D::CallbackWidget::onPose	(	Array< shared_ptr< Surface > > &	surfaceArray,
		Array< shared_ptr< Surface2D > > &	surface2DArray
	)

inlineoverridevirtual

Appends a posed model for this object to the array, if it has a graphic representation.

The posed model appended is allowed to reference the agent and is allowed to mutate if the agent is mutated.

Reimplemented from G3D::Widget.

◆ onSimulation()

virtual void G3D::CallbackWidget::onSimulation	(	RealTime	rdt,
		SimTime	sdt,
		SimTime	idt
	)

inlineoverridevirtual

Reimplemented from G3D::Widget.

◆ onUserInput()

virtual void G3D::Widget::onUserInput ( UserInput * ui )

inlinevirtualinherited

Reimplemented in G3D::GuiWindow, G3D::WidgetManager, G3D::ThirdPersonManipulator, G3D::GConsole, G3D::FirstPersonManipulator, G3D::UprightSplineManipulator, and G3D::CameraControlWindow.

◆ positionalEventZ()

virtual float G3D::Widget::positionalEventZ ( const Point2 & pixel ) const

inlinevirtualinherited

The camera-space z position that this Widget considers this pixel to be at.

Used for positional event (e.g., mouse click) delivery. Higher means closer.

Large negative values are far away. 0 is the closest 3D object. Values greater than zero are used for 2D objects. Returning fnan() [the default] requests the WidgetManager to set hte positionalEventZ to the object's normal event zorder.

See the implementation of ControlPointEditor::positionalEventZ for an example of how to use this with a 3D object.

Reimplemented in G3D::ControlPointEditor.

◆ render()

virtual void G3D::Widget::render ( RenderDevice * rd ) const

inlineoverridevirtualinherited

Inherited from Surface2D.

Implements G3D::Surface2D.

Reimplemented in G3D::GConsole, G3D::GuiWindow, G3D::GuiMenu, and G3D::DebugTextWidget.

◆ setDepth()

virtual void G3D::Widget::setDepth ( float d )

inlinevirtualinherited

Called by the WidgetManager.

This is the depth that the Widget is expected to use when posed as a Surface2D. Subclasses may override or ignore this but it can interfere with the normal handling of rendering.

◆ setManager()

virtual void G3D::Widget::setManager ( WidgetManager * m )

inlinevirtualinherited

Called by the WidgetManager when this module is added to it.

The argument may be nullptr

Reimplemented in G3D::SceneEditorWindow, G3D::ControlPointEditor, G3D::CameraControlWindow, G3D::GameController, G3D::DeveloperWindow, G3D::ProfilerWindow, G3D::TextureBrowserWindow, and G3D::SettingsWindow.

◆ sort()

static void G3D::Surface2D::sort ( Array< shared_ptr< Surface2D >> & array )

staticinherited

Sorts from farthest to nearest.

◆ sortAndRender()

static void G3D::Surface2D::sortAndRender	(	RenderDevice *	rd,
		Array< shared_ptr< Surface2D >> &	array
	)

staticinherited

Calls sort, RenderDevice::push2D, and then render on all elements.

◆ window()

virtual OSWindow* G3D::Widget::window ( ) const

virtualinherited

Returns the operating system window that is currently rendering this Widget.

Reimplemented in G3D::WidgetManager.

Referenced by G3D::FullScreenWidget::bounds().

◆ beforeGraphicsCallback

std::function<void()> G3D::CallbackWidget::beforeGraphicsCallback

◆ m_depth

float G3D::Widget::m_depth

protectedinherited

Referenced by G3D::Widget::depth(), and G3D::Widget::setDepth().

◆ m_manager

WidgetManager* G3D::Widget::m_manager

protectedinherited

The manager, set by setManager().

This cannot be a reference counted pointer because that would create a cycle between the Widget and its manager.
