left of the horizontal scrollbar to split this view, and you can

continue splitting the new views as much as you like. Try it and see.

<h2>wxDynamicSashWindow</h2>
|
|
|
|
|
<p>
|
|
|
|
|
wxDynamicSashWindow widgets manages the way other widgets are viewed.
|
|
|
|
|
When a wxDynamicSashWindow is first shown, it will contain one child
|
|
|
|
|
view, a viewport for that child, and a pair of scrollbars to allow the
|
|
|
|
|
user to navigate the child view area. Next to each scrollbar is a small
|
|
|
|
|
tab. By clicking on either tab and dragging to the appropriate spot, a
|
|
|
|
|
user can split the view area into two smaller views separated by a
|
|
|
|
|
draggable sash. Later, when the user wishes to reunify the two subviews,
|
|
|
|
|
the user simply drags the sash to the side of the window.
|
|
|
|
|
wxDynamicSashWindow will automatically reparent the appropriate child
|
|
|
|
|
view back up the window hierarchy, and the wxDynamicSashWindow will have
|
|
|
|
|
only one child view once again.
|
|
|
|
|
<p>
|
|
|
|
|
As an application developer, you will simply create a wxDynamicSashWindow
|
|
|
|
|
using either the Create() function or the more complex constructor
|
|
|
|
|
provided below, and then create a view window whose parent is the
|
|
|
|
|
wxDynamicSashWindow. The child should respond to
|
|
|
|
|
wxDynamicSashSplitEvents -- perhaps with an OnSplit() event handler -- by
|
|
|
|
|
constructing a new view window whose parent is also the
|
|
|
|
|
wxDynamicSashWindow. That's it! Now your users can dynamically split
|
|
|
|
|
and reunify the view you provided.
|
|
|
|
|
<p>
|
|
|
|
|
If you wish to handle the scrollbar events for your view, rather than
|
|
|
|
|
allowing wxDynamicSashWindow to do it for you, things are a bit more
|
|
|
|
|
complex. (You might want to handle scrollbar events yourself, if,
|
|
|
|
|
for instance, you wish to scroll a subwindow of the view you add to
|
|
|
|
|
your wxDynamicSashWindow object, rather than scrolling the whole view.)
|
|
|
|
|
In this case, you will need to construct your wxDynamicSashWindow without
|
|
|
|
|
the wxDS_MANAGE_SCROLLBARS style and you will need to use the
|
|
|
|
|
GetHScrollBar() and GetVScrollBar() methods to retrieve the scrollbar
|
|
|
|
|
controls and call SetEventHanler() on them to redirect the scrolling
|
|
|
|
|
events whenever your window is reparented by wxDyanmicSashWindow.
|
|
|
|
|
You will need to set the scrollbars' event handler at three times:
|
|
|
|
|
<p>
|
|
|
|
|
<ul>
|
|
|
|
|
<li> When your view is created
|
|
|
|
|
<li> When your view receives a wxDynamicSashSplitEvent
|
|
|
|
|
<li> When your view receives a wxDynamicSashUnifyEvent
|
|
|
|
|
</ul>
|
|
|
