Twaver-HTML5基础学习(38)劈分面板SplitPane

SplitPane

劈分面板

是用于将一块面板劈分成两块的面板，两块面板所占的比例大小是由劈分条的位置来决定的，并且可以通过移动劈分条来动态改变这两块面板的大小。
劈分面板通过设置orientation来进行水平和垂直劈分

使用：

  var BottomPane = new twaver.controls.SplitPane(tree, overview, 'horizontal', 0.3);
  var pane = new twaver.controls.SplitPane(network, BottomPane, 'vertical', 0.6);

四个参数：

Constructor
twaver.controls.SplitPane ( [firstView] [nextView] [orientation] [position] ) twaver.controls.SplitPane
Parameters:
[firstView] Object optional
劈分面版的第一块面板，面板可以为DIV或ControlBase类型的对象[nextView] Object optional
劈分面版的第二块面板，面板可以为DIV或ControlBase类型的对象
[orientation] String optional
劈分的方向，可以为’horizontal’或 ‘vertical’
[position] Number optional
劈分的百分比

horizontal：横向分开两个pane
vertical：纵向分开两个pane;
最后一个参数代表第一个参数对象的大小比例，范围是0-1；

分割好之后，将最终的paneObj设置如下：

 var BottomPane = new twaver.controls.SplitPane(tree, overview, 'horizontal', 0.3);
 var pane = new twaver.controls.SplitPane(network, BottomPane, 'vertical', 0.6);
 var view = pane.getView();
 view.style.left = '0px';
 view.style.top = '0px';
 view.style.right = '0px';
 view.style.bottom = '0px';
 document.getElementById("testID").appendChild(view);
