Member Function Documentation

BOOL RenderWindow::createViewGLContext

(

)

[protected, virtual]

Creates the OpenGL context for drawing on the view.

Returns:

Returns TRUE if the creations went well; FALSE otherwise.

void RenderWindow::DoDataExchange

(

CDataExchange *

pDX

)

[protected, virtual]

BOOL RenderWindow::initOpenGL

(

)

[virtual]

This initializes all stuff needed for the OpenGL rendering.

Returns:

If the setting og the pixel format succeeded, it returns TRUE; otherwise FALSE.

int RenderWindow::OnCreate

(

LPCREATESTRUCT

create_struct

)

[protected]

The MFC framework calls this member function when an application requests that the Windows window be created by calling the Create or CreateEx member function.

Parameters:

create_struct

Points to a CREATESTRUCT structure that contains information about the CWnd object being created.

void RenderWindow::OnDestroy

(

)

[protected]

The framework calls this member function to inform the CWnd object that it is being destroyed.

void RenderWindow::OnDraw

(

CDC *

device_context

)

[protected, virtual]

This overrided method is resonsible for rendering of an image of the document.

Parameters:

device_context

This is used to render an image of the document.

BOOL RenderWindow::OnEraseBkgnd

(

CDC *

device_context

)

[protected]

The MFC framework calls this member function when the CWnd object background needs erasing (for example, when resized).

Parameters:

device_context

Specifies the device-context object.

void RenderWindow::OnMouseMove	(	UINT	flags,
		CPoint	point
	)

The MFC framework calls this member function when the mouse cursor moves.

Parameters:

	flags	Indicates whether various virtual keys are down.
	point	Specifies the x- and y-coordinate of the cursor. These coordinates are always relative to the upper-left corner of the window.

void RenderWindow::OnPaint

(

)

void RenderWindow::OnSize	(	UINT	type,
		int	new_width,
		int	new_height
	)			[protected]

The framework calls this member function after the window's size has changed. Here we adjust the viewport after sizing the window.

Parameters:

	type	Specifies the type of resizing requested.
	new_width	Specifies the new width of the client area.
	new_height	Specifies the new height of the client area. information about the CWnd object being created.

void RenderWindow::OnTimer

(

UINT

event_id

)

[protected]

The framework calls this member function after each interval specified in the SetTimer member function used to install a timer.

Parameters:

event_id

Specifies the identifier of the timer.

BOOL RenderWindow::PreCreateWindow

(

CREATESTRUCT &

create_struct

)

[protected, virtual]

Called before the creation of the Windows window attached to this CWnd object.

Parameters:

create_struct

This structure defines the initialization parameters passed to the window procedure of an application.

Returns:

Returns TRUE if the window creation should continue and FALSE to indicate creation failure.

void RenderWindow::recalc

(

)

void RenderWindow::redraw

(

)

void RenderWindow::renderScene

(

)

[virtual]

Renders the scene of the current OpenGL view.

void RenderWindow::setContext

(

)

Sets the rendering context.

void RenderWindow::setInvViewMatrix

(

matrix44

matr

)

BOOL RenderWindow::setupPixelFormat

(

)

[protected]

Sets the format of the pixels to draw.

Returns:

If the setting of the pixel format succeeded, it returns TRUE; otherwise FALSE.

void RenderWindow::setVolumeLoader

(

VolumeLoader *

vol_load

)

void RenderWindow::swapGLBuffers

(

)

[protected]

Sets the device context.
