ClassGL 3.6 Library Reference

COpenGL::OnSize

virtual void OnSize( UINT nType, int cx, int cy );

Parameters

nType
Specifies the type of resizing requested. This parameter can be one of the following values:

SIZE_MAXIMIZED Window has been maximized. SIZE_MINIMIZED Window has been minimized. SIZE_RESTORED Window has been resized, but neither SIZE_MINIMIZED nor SIZE_MAXIMIZED applies. SIZE_MAXHIDE Message is sent to all pop-up windows when some other window is maximized. SIZE_MAXSHOWMessage is sent to all pop-up windows when some other window has been restored to its former size.

cx Specifies the new width of the client area.

cy Specifies the new height of the client area.

Remarks

The application should pass WM_SIZE events information from the object window to the COpenGL object by using the OnSize method function. The OnSize method function sets rendering context transformations according to cx, cy parameters and the current window resize mode.

Example

class COglSampleView : public CView
{
  // specify operations or attributes as desired …

public:
  COpenGL     m_OpenGL;
  // specify operations or attributes as desired …
};

void COglSampleView::OnSize(UINT nType, int cx, int cy) 
{
  CView::OnSize(nType, cx, cy);
  // COpenGL object resize window event processing
  m_OpenGL.OnSize( nType, cx, cy );
}
