Remarks
A button's style determines how the button appears and how it responds to user input.
Before calling SetButtonStyle, call the GetButtonStyle member function to retrieve the button or separator style.
Observação
You can also set button states using the nStyle parameter; however, because button states are controlled by the ON_UPDATE_COMMAND_UI handler, any state you set using SetButtonStyle will be lost during the next idle processing. See How to Update User-Interface Objects and TN031: Control Bars for more information.
