444.0. "UIL Question" by HGOVC::KENBERKUN (Klaatu Barato Nikto) Tue Mar 21 1989 07:47

I have a question about how to most effectively use UIL.  

I am creating a main window widget, then another window within it that 
I actually write graphics into.  The code segment below shows how I am 
doing this with two calls to DwtFetchWidgets.  I have also included 
the UIL segment.

This works perfectly well, but it doesn't strike me as very elegant.  
I feel like I am missing a point somewhere.  Shouldn't I be able to 
declare this somewhere as a heirarchy and with one call go off and 
create the whole thing?  This is a simple case, but obviously it 
generalizes very quickly into large hierarchies.  Is there a place 
within UIL where I indicate that one window is a child of another?

Thanks for any and all suggestions.

Here is the relevant C code:

	.
	.
	.
    DwtInitializeDRM();

    toplevel = XtInitialize(	"Yadman",
				"TopLevel",
				NULL,
				0,
				&argc,
				&argv );

    if ( DwtOpenHierarchy(	1,
				UID_database,
				NULL,
				&Hierarchy ) != DRMSuccess )
				error( "Can't open hierarchy!" );

    DwtRegisterDRMNames(    callback_namevec, callback_num );


    if ( DwtFetchWidget(	Hierarchy,
				"MainWindow",
				toplevel,
				&mainwidget,
				&dummy ) != DRMSuccess )
				error( "Can't fetch main window!" );

    if ( DwtFetchWidget(	Hierarchy,
				"WorkWindow",
				mainwidget,
				&workwidget,
				&dummy ) != DRMSuccess )
				error( "Can't fetch work window!" );
    XtManageChild ( workwidget);
    XtManageChild ( mainwidget);
    XtRealizeWidget( toplevel);
	.
	.
	.

And here is the UIL code:


	.
	.
	.
object

	MainWindow : exported main_window 
	    {
	     arguments {
		x = 100;
		y = 100;
		width = 400;
		height = 400;
	     };
	     callbacks {
		create = procedure WidgetIDproc( k_MainWindow );
	     };
	     controls {
		menu_bar   MenuBar;
	     };
	};
	
	WorkWindow : exported window
	    {
	     arguments {
		x = 100;
		y = 100;
		width = 400;
		height = 400;
	    };
	    callbacks {
		create = procedure WidgetIDproc (k_WorkWindow );
		expose = procedure MyExpoproc ( k_WorkWindow );
	    };
	};
	.
	.
	.
    

    In your uil module, include the work window in the CONTROLS
    list of the main-window widget. Then fetching the main window
    will get you the work window too.

    Thanks very much, I'll give that a go.

    Well...
    
    I'm still missing something.  I added the following line in the
    controls section of MainWindow
    
    Window WorkWindow;
    
    Then I eleminated the second call to DwtFetchWidget.
    
    No good.  It still doesn't bring up the workwindow widget.  I tried
    all kinds of combinations of fetching and managing, etc.  I wasn't
    getting anywhere, so can someone please be kind enough to post an
    example.
          
    thanks in advance,
    
    Ken B.

    Well, if you included *exactly* "Window WorkWindow", and you're
    using the "case_sensitive" mode of UIL, you should use instead
    "window WorkWindow". Keywords must be lowercase.

Can I suggest taking a look at the decburger example...on VMS it's
in decw$examples:decburger.*   It may look confusing at first, but it's
really a great place to start when learning UIL.

    Still having problems, question continued in note 463.

Ken,

have you looked at the UIL conference on CLT?

Kris..

    re .7
    
    Good Idea, Kris, I hadn't looked there.  I will.
    
    Thanks,
    
    Ken

How can I get a specific simple text widget to take_focus.

i.e. Like the password widget on the login screen after you type a username.
