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

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