Member variable XbpPushButton():default Foundation
Specifies the pushbutton to be the default button of the form.
The instance variable :default determines whether the XbpPushbutton object is the default pushbutton of the modal form it is created in. A modal form is an XbpDialog or XbpCrt object shown using XbpCrt:showModal() or XbpDialog:showModal(), respectively. A modal form's default button is displayed with a special visualization (usually a frame drawn around the button) and represents the default action defined for the form. A default pushbutton usually has a caption such as 'Ok' or 'Confirm' assigned to its :caption instance variable. Selecting such a pushbutton usually initiates an operation such as saving data or returning a value.
If the logical value .T. (TRUE) is assigned to the :default instance variable of an XbpPushbutton object, the code block contained in the :activate callback slot is executed automatically by method :showModal() whenever the user presses the RETURN key.
