2975.0. "Access Violation on XtmanageChild" by METIS::FARRELL () Thu Jun 21 1990 12:29

    
    Hello,
    
    I am having a strange problem, and the error is not helping me find 
    it.
    
    I want to create an options menu. (i.e. When the user pushes the button
    an option menu will appear with some choices in it. (similar to the
    middle button on the window icon box under DECW V5.3+)
    
    Anyway, I create an Option menu
    
    widget1 = DwtOptionMenuCreate(main_widget,"myname",NULL,0);
    /* Set foreground/background colors in XtSetArg calls */
    widget2 = DwtMenuPulldownCreate(tmp_widget,temp,args,2);  
    /* Then I add some push button widgets as children of the Pulldown menu */
    
    Now I can XtManageChild on widget1 ok, but when I try to manage
    widget2, at any time, I get an access violation!?!
    
    I am also trying to do the same thing using a PullDownMenuEntry instead
    of a optionmenu, and I get the same results.
    
    Could someone tell me what I am doing wrong?  The widget2 value looks
    ok upon the call return, and this is a legal child (control) of both
    an optionMenu and a PullDownMenuEntry.
    
    I am lost,
    
    Any/all help would be appreciated,
    
    thanks,

   Try creating widget2 with the same parent as widget1 (i.e. main_widget).
   Then, make sure you've set the subMenuId resource of widget1 to point 
   to widget2 (so its probably better to create widget2 before widget1).
   Finally, only manage widget1 -- widget2 will be automatically managed 
   when the proper mouse actions occur.
