Detailed Description

`Class: kodi::gui::controls::CRendering`

Window control for rendering own parts
This rendering control is used when own parts are needed.

You have the control over them to render direct OpenGL or DirectX content to the screen set by the size of them.

Alternative can be the virtual functions from t his been ignored if the callbacks are defined by the CRendering_SetIndependentCallbacks function and class is used as single and not as a parent class.

It has the header #include <kodi/gui/controls/Rendering.h> be included to enjoy it.

Here you find the needed skin part for a rendering control.

Note: The call of the control is only possible from the corresponding window as its class and identification number is required.

Function Documentation

◆ CRendering()

CRendering	(	CWindow *	window,
		int	controlId
	)

inline

Construct a new control.

Parameters

[in]	window	Related window control class
[in]	controlId	Used skin xml control id

◆ ~CRendering()

~CRendering ( )

inlineoverride

Destructor.

◆ Create()

virtual bool Create	(	int	x,
		int	y,
		int	w,
		int	h,
		kodi::HardwareContext	device
	)

inlinevirtual

To create rendering control on Add-on.

Function creates the needed rendering control for Kodi which becomes handled and processed from Add-on

Note: This is callback function from Kodi to Add-on and not to use for calls from add-on to this function.

Parameters

[in]	x	Horizontal position
[in]	y	Vertical position
[in]	w	Width of control
[in]	h	Height of control
[in]	device	The device to use. For OpenGL is empty on Direct X is the needed device send.

Returns: Add-on needs to return true if successed, otherwise false.

Note: The kodi::HardwareContext is basically a simple pointer which has to be changed to the desired format at the corresponding places using static_cast<...>(...).

◆ Render()

virtual void Render ( )

inlinevirtual

Render process call from Kodi.

Note: This is callback function from Kodi to Add-on and not to use for calls from add-on to this function.

◆ Stop()

virtual void Stop ( )

inlinevirtual

Call from Kodi to stop rendering process.

Note: This is callback function from Kodi to Add-on and not to use for calls from add-on to this function.

◆ Dirty()

virtual bool Dirty ( )

inlinevirtual

Call from Kodi where add-on becomes asked about dirty rendering region.

Note: This is callback function from Kodi to Add-on and not to use for calls from add-on to this function.

Returns: True if a render region is dirty and need rendering.

◆ SetIndependentCallbacks()

void SetIndependentCallbacks	(	kodi::gui::ClientHandle	cbhdl,
		bool(*)(kodi::gui::ClientHandle cbhdl, int x, int y, int w, int h, kodi::HardwareContext device)	CBCreate,
		void(*)(kodi::gui::ClientHandle cbhdl)	CBRender,
		void(*)(kodi::gui::ClientHandle cbhdl)	CBStop,
		bool(*)(kodi::gui::ClientHandle cbhdl)	CBDirty
	)

inline

If the class is used independent (with "new CRendering") and not as parent (with "cCLASS_own : CRendering") from own must be the callback from Kodi to add-on overdriven with own functions!

Parameters

[in]	cbhdl	Addon related class point where becomes given as value on related functions.
[in]	CBCreate	External creation function pointer, see also Create about related values
[in]	CBRender	External render function pointer, see also Render about related values
[in]	CBStop	External stop function pointer, see also Stop about related values
[in]	CBDirty	External dirty function pointer, see also Dirty about related values
