Member Function Documentation

virtual HWND vlWin32::Win32Context::hwnd

(

)

const [pure virtual]

Implemented in vlWin32::Win32Window, and vlMFC::MFCWindow.

HDC vlWin32::Win32Context::hdc

(

)

const [inline]

HGLRC vlWin32::Win32Context::hglrc

(

)

const [inline]

void Win32Context::shareOpenGLResources

(

HGLRC

hGLRC

)

Use this function when you want two OpenGL contexts to share their resources (display lists, textures, shader objects, buffer objects etc.

) Equivalent to wglShareLists(this->hglrc(), hGLRC)

Remarks:

If you want to share resources among two or more OpenGL contexts, you must call this function before you start creating any resources.

void Win32Context::makeCurrent

(

)

[virtual]

Reimplemented from vl::OpenGLContext.

void Win32Context::update

(

)

[virtual]

Reimplemented from vl::OpenGLContext.

void Win32Context::swapBuffers

(

)

[virtual]

Reimplemented from vl::OpenGLContext.

void Win32Context::setWindowTitle

(

const vl::String &

title

)

[virtual]

Reimplemented from vl::OpenGLContext.

void Win32Context::show

(

)

[virtual]

Reimplemented from vl::OpenGLContext.

void Win32Context::hide

(

)

[virtual]

Reimplemented from vl::OpenGLContext.

void Win32Context::getFocus

(

)

[virtual]

Reimplemented from vl::OpenGLContext.

void Win32Context::setMouseVisible

(

bool

visible

)

[virtual]

Reimplemented from vl::OpenGLContext.

void Win32Context::setMousePosition	(	int	x,
		int	y
	)			[virtual]

Reimplemented from vl::OpenGLContext.

void Win32Context::setPosition	(	int	x,
		int	y
	)			[virtual]

Reimplemented from vl::OpenGLContext.

vl::ivec2 Win32Context::position

(

)

const [virtual]

Reimplemented from vl::OpenGLContext.

void Win32Context::setSize	(	int	w,
		int	h
	)			[virtual]

The actual size of the OpenGL context, i.e.

the client area if this is a window. Note that if this Win32Window has window decorations the actual window size will be bigger than the given w and h parameters.

Reimplemented from vl::OpenGLContext.

vl::ivec2 Win32Context::size

(

)

const [virtual]

The actual size of the OpenGL context, i.e. the client area if this is a window.

Reimplemented from vl::OpenGLContext.

void Win32Context::setWindowSize	(	int	w,
		int	h
	)

Sets the size of the window. Note that if this Win32Window has window decorations the actual OpenGL context will be smaller than the given w and h parameters.

vl::ivec2 Win32Context::windowSize

(

)

const

Returns the size of the window and not the client area.

Use the size() method if you need the size of the actual OpenGL rendering context.

Note:

windowSize() can be different from size() because of the space taken by the window caption and decorations.

bool Win32Context::setFullscreen

(

bool

fullscreen_on

)

[virtual]

Reimplemented from vl::OpenGLContext.

void Win32Context::quitApplication

(

)

[virtual]

Calls the PostQuitMessage(0) function (Win32 API).

Reimplemented from vl::OpenGLContext.

bool Win32Context::init	(	HGLRC	share_context,
		const vl::String &	title,
		const vl::OpenGLContextFormat &	fmt,
		int	x,
		int	y,
		int	width,
		int	height
	)			[protected]
