+The Dialog widget implements a commonly used interaction semantic to
+prompt for auxiliary input from a user. For example, you can use a
+Dialog widget when an application requires a small piece of information,
+such as a filename, from the user. A Dialog widget, which is simply a
+special case of the Form widget, provides a convenient way to create a
+preconfigured form.

+<!-- .LP -->
+The typical Dialog widget contains three areas. The first line
+contains a description of the function of the Dialog widget, for
+example, the string <emphasis remap='I'>Filename:</emphasis>. The second line contains an area
+into which the user types input. The third line can contain buttons
+that let the user confirm or cancel the Dialog input. Any of these
+areas may be omitted by the application.

+<!-- .IN "Dialog widget" "layout semantics" -->
+<para>
+The Dialog widget uses two different sets of layout seman-
+tics. One is used when initially laying out the children.
+The other is used when the Dialog is resized.
+</para>
+<para>
+The first layout method uses the <function>fromVert</function> mand <function>fromHoriz</function>
+resources to place the children of the Dialog. A single
+pass is made through the Dialog widget's children in the
+order that they were created. Each child is then placed in
+the Dialog widget below or to the right of the widget speci-
+fied by the <function>fromVert</function> mand <function>fromHoriz</function> mresources. The distance
+the new child is placed from its left or upper neighbor is
+determined by the <function>horizDistance</function> mand <function>vertDistance</function> mresources.
+This implies some things about how the order of creation
+affects the possible placement of the children. The Form
+widget registers a string to widget converter which does not
+postpone conversion and does not cache conversion results.
+</para>
+<para>
+
+The second layout method is used when the Dialog is resized.
+It does not matter what causes this resize, and it is possi-
+ble for a resize to happen before the widget becomes visible
+(due to constraints imposed by the parent of the Dialog).
+This layout method uses the <function>bottom</function> ,
+<function>top</function> , <function>left</function> , and
+<function>right</function>
+resources. These resources are used to determine what will
+happen to each edge of the child when the Dialog is resized.
+If a value of <function>XawChain</function>
+<emphasis remap='I'>&lt;something&gt;</emphasis>
+ is specified, the the edge
+of the child will remain a fixed distance from the <emphasis remap='I'>chain</emphasis>
+edge of the Dialog. For example if <function>XawChainLeft</function>
+mis specified for the <function>right</function> mresource of a child
+then the right edge
+of that child will remain a fixed distance from the left
+edge of the Dialog widget. If a value of <function>XawRubber</function> mis spec-
+ified, that edge will grow by the same percentage that the
+Dialog grew. For instance if the Dialog grows by 50% the
+left edge of the child (if specified as <function>XawRubber</function> mwill be
+50% farther from the left edge of the Dialog). One must be
+very careful when specifying these resources, for when they
+are specified incorrectly children may overlap or completely
+occlude other children when the Dialog widget is resized.
