	64	You can drag the little tabs above the vertical scrollbar, or to the
	65	left of the horizontal scrollbar to split this view, and you can
	66	continue splitting the new views as much as you like. Try it and see.
	67
	68	In this case the views also share the same document so changes in one
	69	are instantly seen in the others. This is a feature of the
	70	wxStyledTextCtrl that is used for the view class in this sample.

	110	<h2>wxDynamicSashWindow</h2>
	111	<p>
	112	wxDynamicSashWindow widgets manages the way other widgets are viewed.
	113	When a wxDynamicSashWindow is first shown, it will contain one child
	114	view, a viewport for that child, and a pair of scrollbars to allow the
	115	user to navigate the child view area. Next to each scrollbar is a small
	116	tab. By clicking on either tab and dragging to the appropriate spot, a
	117	user can split the view area into two smaller views separated by a
	118	draggable sash. Later, when the user wishes to reunify the two subviews,
	119	the user simply drags the sash to the side of the window.
	120	wxDynamicSashWindow will automatically reparent the appropriate child
	121	view back up the window hierarchy, and the wxDynamicSashWindow will have
	122	only one child view once again.
	123	<p>
	124	As an application developer, you will simply create a wxDynamicSashWindow
	125	using either the Create() function or the more complex constructor
	126	provided below, and then create a view window whose parent is the
	127	wxDynamicSashWindow. The child should respond to
	128	wxDynamicSashSplitEvents -- perhaps with an OnSplit() event handler -- by
	129	constructing a new view window whose parent is also the
	130	wxDynamicSashWindow. That's it! Now your users can dynamically split
	131	and reunify the view you provided.
	132	<p>
	133	If you wish to handle the scrollbar events for your view, rather than
	134	allowing wxDynamicSashWindow to do it for you, things are a bit more
	135	complex. (You might want to handle scrollbar events yourself, if,
	136	for instance, you wish to scroll a subwindow of the view you add to
	137	your wxDynamicSashWindow object, rather than scrolling the whole view.)
	138	In this case, you will need to construct your wxDynamicSashWindow without
	139	the wxDS_MANAGE_SCROLLBARS style and you will need to use the
	140	GetHScrollBar() and GetVScrollBar() methods to retrieve the scrollbar
	141	controls and call SetEventHanler() on them to redirect the scrolling
	142	events whenever your window is reparented by wxDyanmicSashWindow.
	143	You will need to set the scrollbars' event handler at three times:
	144	<p>
	145	<ul>
	146	<li> When your view is created
	147	<li> When your view receives a wxDynamicSashSplitEvent
	148	<li> When your view receives a wxDynamicSashUnifyEvent
	149	</ul>
	150	</body></html>
