+@section overview_dialog_autoscrolling Automatic Scrolled Dialogs
As an ever greater variety of mobile hardware comes to market, it becomes more
-imperative for wxWidgets applications to adapt to these platforms without putting
-too much burden on the programmer. One area where wxWidgets can help is in adapting
-dialogs for the lower resolution screens that inevitably accompany a smaller form factor.
-wxDialog therefore supplies a global wxDialogLayoutAdapter class that implements
-automatic scrolling adaptation for most sizer-based custom dialogs.
-
-Many applications should therefore be able to adapt to small displays with little
-or no work, as far as dialogs are concerned.
-By default this adaptation is off. To switch scrolling adaptation on globally in
-your application, call the static function wxDialog::EnableLayoutAdaptation passing @true.
-You can also adjust adaptation on a per-dialog basis by calling
-wxDialog::SetLayoutAdaptationMode with one of @c wxDIALOG_ADAPTATION_MODE_DEFAULT
-(use the global setting), @c wxDIALOG_ADAPTATION_MODE_ENABLED or @c wxDIALOG_ADAPTATION_MODE_DISABLED.
-
-The last two modes override the global adaptation setting.
-With adaptation enabled, if the display size is too small for the dialog, wxWidgets (or rather the
-standard adapter class wxStandardDialogLayoutAdapter) will make part of the dialog scrolling,
-leaving standard buttons in a non-scrolling part at the bottom of the dialog.
-This is done as follows, in wxDialogLayoutAdapter::DoLayoutAdaptation called from
-within wxDialog::Show or wxDialog::ShowModal:

-@li If that search failed, wxWidgets looks for a horizontal wxBoxSizer with one or more
- standard buttons, with identifiers such as @c wxID_OK and @c wxID_CANCEL.
-@li If that search failed too, wxWidgets finds 'loose' standard buttons (in any kind of sizer)
- and adds them to a wxStdDialogButtonSizer.
- If no standard buttons were found, the whole dialog content will scroll.
-@li All the children apart from standard buttons are reparented onto a new ::wxScrolledWindow
- object, using the old top-level sizer for the scrolled window and creating a new top-level
- sizer to lay out the scrolled window and standard button sizer.

-In addition to switching adaptation on and off globally and per dialog,
