CMFCDropDownToolbarButton::OnClick

Called by the framework when the user clicks the mouse button.

virtual BOOL OnClick(
   CWnd* pWnd,
   BOOL bDelay = TRUE
);

Parameters

• [in] pWnd
  The parent window of the toolbar button.

• [in] bDelay
  TRUE if the message should be handled with a delay.

Return Value

Nonzero if the button processes the click message; otherwise 0.

Remarks

This method extends the base class implementation, CMFCToolBarButton::OnClick, by updating the state of the drop-down toolbar.

When a user clicks the toolbar button, this method creates a timer that waits the length of time specified by the CMFCDropDownToolbarButton::m_uiShowBarDelay data member and then opens the drop-down toolbar by using the CMFCDropDownToolbarButton::DropDownToolbar method. This method closes the drop-down toolbar the second time the user clicks the toolbar button.
