I've been struggling with two problems that I can't resolve.
1) I have a simple question about appending MenuItem objects
to menubars. I want to know how to append a menu item to
the far right of a menubar. It seems that Menu automatically
sticks a hglue() at the end of a given menubar. Thus, the
last menu item can never be right justified.
It should simple to do, but nothing seems to do the trick.
Beside generating a whole new derived class, there must
be an easier way.
2) I'm also having problems with the FieldEditor. I noticed that
a previous posting mentioned this problem, but I never found the
solution. Below is a reprint of the problem.
; Article 4094 of comp.windows.interviews:
; Subject: 3.1B FieldEditors
;
; I need some help with FieldEditor.
;
;I am using version 3.1 Beta of InterViews. I'm trying to create a popup
;containing a FieldEditor and have the FieldEditor receive all keyboard
;events as long as the mouse is within the popup. A sample of my code is:
;
;void
;Sample::CreatePopup()
;{
; WidgetKit* kit = WidgetKit::instance();
; Style* style = new Style(kit-;style());
; style-;attribute("name", "sample");
; LayoutKit* layout = LayoutKit::instance();
; DialogKit* dialog = DialogKit::instance();
; FieldEditor* ed = dialog-;field_editor(String("Sample Entry"), style);
; InputHandler* h = new InputHandler(
; kit-;inset_frame(
; layout-;margin(
; layout-;hbox(
; layout-;vcenter(kit-;label("Label: ")),
; layout-;vcenter(ed)
; ),
; 20, 20
; )
; ),
; style
; );
; h-;append_input_handler(ed);
; h-;focus(ed);
; window = new ApplicationWindow(h);
; window-;style(style);
; window-;map();
;}
;
;This creates the popup with the field editor but the editor only accepts
;keyboard input while the mouse pointer is on the editor itself or the label.
;It does not accept input if the mouse is in the margin around the label/editor
;box.
;
;Am I missing something? The field editors in doc seem to work correctly and
;I modeled this code after doc's dialogs.c file. Any suggestions would be
;appreciated!
By the way, I'm currently using Version 3.0.1 (if that helps any).
Thanks.

Put a menu item containing a piece of hglue(fil, 0, fil) before the right-adjusted items.
By making the natural size infinite, you force the box to shrink this glue
instead of stretching the glue at the end of the menu bar.

The problem is that picks go through the margins and frames.
Try putting a primitive target behind the dialog to catch all picks,
e.g.,
layout->back(
kit->inset_frame(...),
new Target(nil, TargetPrimitiveHit)
)

With help and a little bit of work, I finally implemented the right justified menu items. For some reason, appending a blank menu item with a hglue(fil,0,fil) caused my program to crash while trying to display it. I fixed this problem by using hglue(9.0E6,0,9.0E6). I guess menu append has problems with fil (ie. 10.0E6). To prevent the menubar from filling the screen, I used layout->h_natural_span to set the natural size of the menubar. Unfortunately, I still can't resolve my problem with the Field Editors. To refresh your memory, the following is an excerpt of the response: |> 2) I'm also having problems with the FieldEditor.

Below is a reprint of the problem. >The problem is that picks go through the margins and frames. >Try putting a primitive target behind the dialog to catch all picks, >e.g., > > layout->back( > kit->inset_frame(...), > new Target(nil, TargetPrimitiveHit) > ) Now, when trying to implement the targeting scheme, I received compiler errors. "back" is not a member function of LayoutKit. Scanning the other member functions available in LayoutKit, I tried using "overlay". So instead of using "layout->back", I used "layout->overlay". I included the glyph I wanted into the "inset_frame" parameter. I then included the whole thing in a box. It of course compiled, but didn't solve my problem. The FieldEditor is still only live when the arrow is within the editor itself. I'm pretty sure that I must be interpretting something wrong. I have one idea of deriving a new class from FieldEditor, but it's not pretty. By the way, I'm currently using IV3.1 Beta 2 on ULTRIX with the Xlib from DEC (if that helps any).
