        <para>Note that point-to-focus places a number of restrictions on
        GNOME applications that are not present in environments such as MacOS
        or Windows. For example, utility windows shared between multiple
        document windows, like the toolbox in the GIMP Image Editor, cannot be
        context-sensitive— that is, they cannot initiate an action such as
        <guibutton>Save</guibutton> on the current document. This is because
        while moving the mouse from the current document to the utility
        window, the user could inadvertantly pass the pointer over a different
        document window, thus changing the focus and possibly saving the wrong
        document.</para>

    <para>A primary window usually presents a view of the user's data,

    drawing program, or calculations in a calculator or spreadsheet
    application. It may also be a view of something more abstract, like a

    window, and more than one kind of primary window.</para>

        <para>MDI has several inherent usability problems, so its use is

        allow multiple instances of your application to be run simultaneously.
        In either case, this leaves it for the window manager (acting on the
        user's preferences) rather than your application to decide how to
        group and present document windows from the same application.</para>

      <sect3 id="csdi">
        <title>Controlled Single Document Interface (CSDI)</title>
        <para>In a typical SDI application, document windows are treated as
        primary. For example, when all document windows have been closed, the 
        application (including utility windows) exits as well. In CSDI a utility
        window is treated as the primary window. For example, closing this
        utility window will close all document windows and exit the application.</para>

        <warning><para>Using CSDI is <emphasis role="bold">not</emphasis> recommended</para></warning>

        <para>CSDI is sometimes used because document windows might be too
        small to have menu bars. Typically this is not the normal use case for the
        application, but does represent a significant minority use case. For
        example, an image editor being used to edit small web page elements will
        often result in very small document windows that cannot accomodate
        a title bar.</para>

        <remark>We should really have a way of doing overflow automatically
                in GTK+.</remark>

        <para>A better way to address this problem is to allow menu bars to "collapse"
        into an overflow button, in much the same way toolbars operate when the window
        shrinks to below the toolbar width. This allows for small windows, but also
        provides an opportunity for people to figure out where their menus have gone.</para>

        <tip><para>Note that if very small documents are the <emphasis>primary</emphasis> use 
        case for your application, you should consider finding a means to avoid windows
        altogether. Windows are not an effective interface for dealing with large
        numbers of small items. Consider looking for a fixed/automated layout system
        for presenting the "documents". Also consider if the "documents" will be primarily
        used in a higher level grouping, in which case that grouping could become the
        document instead.</para></tip>

    <para>An alert provides information about the state of the application

    intrusion into the user's work, do not use them except where necessary
    to avoid potential data loss or other serious problems.</para>

    <para>
 	An alert has a border similar to that of a dialog, and is object modal. 
    </para>
    <para>

	example, an appointment reminder alert may be shown after
	the main calendar application window has been closed.

    <formalpara>
      <title>Titelformat</title>

      <para>Alert windows have no titles, as the title would usually
      unnecessarily duplicate the alert's primary text. This way, users
      can read and respond to alerts more quickly as there is less visual
      noise and confounding text.</para>
    </formalpara>

    <remark>Without a title, how does a screenreader user identify an alert
    window? -Calum</remark>

    <remark>The screen-reader finds out its an alert (do we need a WM
    mechanism for this?) and reads the primary text to identify the alert. The
    whole point for removing the title is that its redundant with the primary
    text, and puts more crap on the screen to be read. This problem applies
    double to users with screenreaders (i.e. reducing extra crap helps them
    even more). -Seth</remark>

    <remark>An alert still needs to have an appropriate accessible description
    (perhaps the primary text of the alert itself?), so a screenreader user
    hears some information about its content when they focus it. -Calum</remark>

        <para>Write button labels as imperative verbs, for example
        <guibutton>Save</guibutton>, <guibutton>Print</guibutton>. This allows
        users to select an action with less hesitation. An active phrase also
        fits best with the button's role in initiating actions, as
        contrasted with a more passive phrase. For example
        <guibutton>Find</guibutton> and <guibutton>Log In</guibutton> are
        better buttons than <guibutton>Yes</guibutton> and
        <guibutton>OK</guibutton>.</para>

            affirmative button if <guibutton>Cancel</guibutton> is not

            confirmation alert. This is an alternative to the primary
            suggested action <guibutton>Save</guibutton> and the

        <para>Create a new GtkDialog window specifying the number of buttons
        you wish the alert to contain (and a help button if appropriate). The
        GtkDialog will contain a GtkVBox with an empty upper row, and a lower

        row, place a new GtkHBox. In the left column of the GtkHBox place a
        GtkImage. In the right column of the GtkHBox place a GtkLabel. Inside
        the GtkLabel place <replaceable>Primary Text</replaceable> first

        then put two linebreaks (return), then place

present it immediately. If the user confirms closing without saving,
hide the alert and the document or application  window immediately, 
before doing any necessary internal clean-up.
If the user chooses to save before
closing, hide the alert immediately but show the document window until the document is
saved, in case an error occurs.  Then hide the document window immediately after it has been saved successfuly.

      <para>Authentication alerts prompt the user for information necessary to
      gain access to protected resources, such as their username or password.
      Authentication alerts are a special kind of alert because they are both
      routine and largely unavoidable. Every attempt should be made to retain
      information entered into an authentication alert as long as is possible
      within security constraints.</para>

    <!--<remark>FIXME: need to finish this section</remark>-->

    <para>An assistant is a secondary window that guides the user through an
    operation by breaking it into sequential steps. Assistants are useful for
    making complex operations less intimidating, as they restrict the
    information visible to the user at any given moment.</para>

    <para>Because assistants provide a relatively small number of controls on
    the screen at any given time, they have sufficient space for inline
    documentation. Therefore, do not include a <guibutton>Help</guibutton>
    button in an assistant window. If you cannot make an operation
    sufficiently clear in an assistant without resorting to a
    <guibutton>Help</guibutton> button, you need to simplify it further.</para>

    <para>Assistants do have major downsides. After using an assistant
    it is often hard to figure out where the individual settings aggregated
    into the assistant are stored. Often people will resort to re-running
    the assistant, re-entering many settings that they don't want to change.
    <remark>Why do they need to re-enter anything? The assistant should
	be populated with the exisiting settings whenever it is run.</remark>
    </para>

    <warning><para>Assistants are often used in situations where a better
    solution would be to simplify, or even better automate, the process.
    Before using an assistant to step people through a complex operation,
    consider if the operation can be fundamentally simplified so an
    assistant is unnecessary.</para></warning>
