CWnd::OnStyleChanging

 

The framework calls this member function when the SetWindowLong function is about to change one or more of the window's styles.


      afx_msg void OnStyleChanging(
   int nStyleType,
   LPSTYLESTRUCT lpStyleStruct 
);

nStyleType

Specifies whether the window's extended or nonextended styles have changed. This parameter can be a combination of the following values:

  • GWL_EXSTYLE   The window's extended styles have changed.

  • GWL_STYLE   The window's nonextended styles have changed.

lpStyleStruct

Points to a STYLESTRUCT structure that contains the new styles for the window. An application can examine the styles and change them.

System_CAPS_noteNote

This member function is called by the framework to allow your application to handle a Windows message. The parameters passed to your function reflect the parameters received by the framework when the message was received. If you call the base-class implementation of this function, that implementation will use the parameters originally passed with the message and not the parameters you supply to the function.
