Member variable XbpStatusBar():caption Foundation
Contains the caption string displayed by an XbpStatusBar object.
The instance variable :caption contains a character string that defines the caption displayed by an XbpStatusBar object. When a character string is assigned to the :caption instance variable, the XbpStatusBar object displays the caption string in a single panel that spans the whole width of the statusbar's parent object.
Using the :caption instance variable provides a convenient way for displaying simple status messages. Also, assigning a string to :caption allows an application to temporarily hide the status bar panels displayed by the XbpStatusBar object. For example, a lengthy operation sometimes results in the temporary unresponsiveness of the application. In such a case, the application may assign the character string "Busy..." to its statusbar's :caption instance variable. After that, all panels (including those displaying key state information) will be hidden until the operation concluded and the application is again ready to respond to user interaction.
To redisplay status bar panels temporarily hidden by a simple status message, assign the empty string ("") to the :caption instance variable.
