Called by the framework when the parent toolbar handles a WM_HELPHITTEST message.
virtual BOOL OnContextHelp(
CWnd* pWnd
);
Parameters
- [in] pWnd
The parent window of the toolbar button.
Return Value
Nonzero if the button processes the help message; otherwise 0.
Remarks
This method extends the base class implementation (CMFCToolBarButton::OnContextHelp) by calling the CMFCDropDownToolbarButton::OnClick method with bDelay set to FALSE. This method returns the value that is returned by CMFCDropDownToolbarButton::OnClick.
For more information about the WM_HELPHITTEST message, see TN028: Context-Sensitive Help Support.
