Member Function Documentation

BOOL OpenGLView::createViewGLContext

(

)

[protected, virtual]

Creates the OpenGL context for drawing on the view.

Returns:

Returns TRUE if the creations went well; FALSE otherwise.

CVolumeRendererDoc * OpenGLView::GetDocument

(

)

[inline]

Call this function to get a pointer to the view's document.

Returns:

This returns a pointer to the CDocument object associated with the view. NULL if the view is not attached to a document.

BOOL OpenGLView::initOpenGL

(

)

[virtual]

This initializes all stuff needed for the OpenGL rendering.

Returns:

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

Reimplemented in BlackView, XYView, XZView, and YZView.

int OpenGLView::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.

Reimplemented in BlackView, XYView, XZView, and YZView.

void OpenGLView::OnDestroy

(

)

[protected]

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

Reimplemented in BlackView, XYView, XZView, and YZView.

void OpenGLView::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 OpenGLView::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.

Reimplemented in BlackView, XYView, XZView, and YZView.

void OpenGLView::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 OpenGLView::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.

Reimplemented in BlackView, XYView, XZView, and YZView.

virtual void OpenGLView::renderScene

(

)

[pure virtual]

Renders the scene of the current OpenGL view.

Implemented in BlackView, XYView, XZView, and YZView.

void OpenGLView::setContext

(

)

Sets the rendering context.

BOOL OpenGLView::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 OpenGLView::swapGLBuffers

(

)

[protected]

Sets the device context.

---
