Constructor & Destructor Documentation

gazebo::rendering::GUIOverlay::GUIOverlay

(

)

Constructor.

virtual gazebo::rendering::GUIOverlay::~GUIOverlay ( )

virtual

Destructor.

Member Function Documentation

bool gazebo::rendering::GUIOverlay::AttachCameraToImage	(	CameraPtr &	_camera,
		const std::string &	_windowName
	)

Use this function to draw the output from a rendering::Camera to and overlay window.

Parameters

[in]	_camera	Pointer to the camera.
[in]	_windowName	Name of the window to receive the camera image

Returns

True if successful

bool gazebo::rendering::GUIOverlay::AttachCameraToImage	(	DepthCameraPtr &	_camera,
		const std::string &	_windowName
	)

Use this function to draw the output from a rendering::DepthCamera to and overlay window.

Parameters

[in]	_camera	Pointer to the camera.
[in]	_windowName	Name of the window to receive the camera image

Returns

True if successful

template<typename T >

void gazebo::rendering::GUIOverlay::ButtonCallback ( const std::string &  _buttonName, void(T::*)()  _fp, T *  _obj  )

inline

Register a CEGUI button callback.

Assign a callback to a name button.

Parameters

[in]	_buttonName	Name of the button.
[in]	_fp	Function pointer to the callback.
[in]	_obj	Class pointer that contains _fp.

References callbacks, and gzerr.

void gazebo::rendering::GUIOverlay::CreateWindow	(	const std::string &	_type,

		const std::string &	_parent,
		const math::Vector2d &	_position,
		const math::Vector2d &	_size,
		const std::string &	_text
	)

Create a new window on the overlay.

Parameters

[in]	_type	The window type. This should match a CEGUI window type. See CEGUI::WindowManager::getSingleton().createWindow().
[in]	_name	Unique name for the window.
[in]	_parent	Name of the parent window.
[in]	_position	Position of the window within the parent.
[in]	_size	Size of the window.
[in]	_text	Display title of the window.
