2093.0. "Which menu bar to use?" by TOWNS::RUFFIEUX () Sat Jan 20 1990 18:42

    
    
    I am writing an application in which the main window's menu bar can
    take one of two forms:
    
        -  If the user does not have privilege, the menu bar will contain
           four items.
    
    	-  If the user has a certain privilege (in the application not
    	   VMS) the menu bar will contain the four items of a regular
    	   user plus an additional four.
    
    I was wondering if anyone could recommend a good way to implement this.
    A test has already been set up to determine the type of user.  I just
    need to know the best way to get the proper menu bar up there.  I had
    it set up so the UIL contained the four items that both users get and
    then if the user was priv, I called a routine that created the other
    four items.  The problem with this is that the menu items would
    appear on the menu bar but none of the children, (pulldowns and buttons)
    were working.  I also tried defining two different menu bars in uil
    and managing the proper one.  The problem with this is that the menu
    bar is no longer a child of the toplevel and when I manage it, it does
    not appear on the main window. (it appears first and gets covered up).
    
    Any suggestion,comments,answers will be greatly appreciated...
    
    
    Thank you,
    
    Chris

	I can't help with the problems you've been experiencing, but an alternative approach would be to have all the options always on the menu-bar, but have the privileged ones greyed-out (Sensitive=False) when the application is invoked by an unprivileged user. John

	re .1 Thanks, I know this is an option. I would still like to know if anyone has any other ideas... Thanks, Chris
2093.3	easy in UIL, declare unmanaged and Manage them later	RTL::OBRYAN	When in doubt, let the user decide.	`Sun Jan 21 1990 02:01`	59
	re:.0 As you've recognized, there are two ways to go here: declare things unmanaged and manage them as needed, or delay creation until needed. Let's look at the easiest one to program (the unmanaged approach.) Here is a sample menu bar declared in UIL test_MenuBar : menu_bar { arguments { orientation = DwtOrientationHorizontal; help_widget = pulldown_entry test_Help_Entry; }; controls { pulldown_entry test_File_Entry; unmanaged pulldown_entry test_Edit_Entry; !* unmanaged pulldown_entry test_Customize_Entry; !* pulldown_entry test_Help_Entry; }; }; ! test_MenuBar test_Edit_Entry : pulldown_entry ! The other entries are { ! similarly declared arguments { label_label = k_tst_test_Edit_Entry_str; }; controls { pulldown_menu { controls { push_button test_Cut_Btn; push_button test_Paste_Btn; separator gnc_Sep; push_button test_selall_Btn; }; }; }; callbacks { create = procedure tst_create_proc (k_tst_test_Edit_Entry); }; }; ! test_Edit_Entry In the segment of code in which you have determined that the two invisible Entries need to become visible, simply XtManageChild each of the (saved) Entry widget ids. This particular approach also has the advantage that the two mystery Entries will appear positioned in the menu_bar where you desire them. (Menu_bar places them in the order they were created, with the exception of the designated "help_widget" which always is positioned last.)
