2.9   Tornado Interface Conventions

The following conventions apply uniformly to all of the Tornado graphical tools (the launcher, the project facility, the browser, the debugger, and WindView):

  • Busy Box.  
    The Wind River logo appears in the top right of the main window of each tool. When the tool is busy, it indicates this by animating the logo.

  • Universal Menu Entries.  
    The following menu commands are always present:

    File>Quit
    Shut down the tool.

    About>Tornado
    Identify the version of Tornado.

  • Keyboard Selection from Menus.  
    Every Tornado menu has a one-letter abbreviation, shown by underlining that letter in the menu bar. Press the META shift and that letter to display the menu from the keyboard rather than using the mouse. While the menu is displayed, you can dismiss it without selecting a command by repeating the same META-letter shortcut.

    Within a menu, there are two ways of selecting and executing a command from the keyboard. Each command name also has an underlined letter; press that letter (no META shift at this level) to execute the command immediately. For example, the key sequence META-F Q selects Quit from any File menu. You can also use the arrow keys on your keyboard to highlight each successive menu command in turn; press RETURN (or ENTER) to execute the currently highlighted command.

  • Keyboard Operation of Forms (Dialogs).  
    When a form is displayed, the TAB key selects each text or scrolling-list field in turn (shift-TAB selects them in reverse order). Type directly in a text field to change its value; in scrolling lists, select a new value with the arrow keys.

    When no scrolling list is selected, the arrow keys select in turn each of the toggles or buttons on the form; RETURN (ENTER) switches the highlighted toggle or presses the highlighted button.

  • Left Mouse Selects, Middle Mouse Drags.  
    When there is selectable text in a Tornado display, use the left mouse button to select it. For objects that can be dragged, use the middle mouse button.

  • Folder Hierarchies.  
    Whenever hierarchical data is presented graphically, a folder icon appears at each level of the hierarchy. Click on these folders to hide subordinate information; click again on the folder to reveal it once again.
