BS_DEFPUSHBUTTON top-level constant Null safety
Creates a push button that behaves like a BS_PUSHBUTTON style button, but has a distinct appearance. If the button is in a dialog box, the user can select the button by pressing the ENTER key, even when the button does not have the input focus. This style is useful for enabling the user to quickly select the most likely (default) option.
