RCP布局

我原以为Rcp设计圆角很麻烦，但是后来多方查找资料才发现，其实就像写web页面的样式一样，也很简单

下面我给大家展示下我的代码：这是在viewpart的createPartControl方法里面写的：

我先让大家大致了解一下，RCP的Composite类，其实就是相当于html中的div或table控件，也可以嵌套的。

为了不让大家误解我对我的一部分代码进行说明：IUISizeConstants.UI_HEIGHT和IUISizeConstants.UI_WIDTH是我自己定义的高度和宽度的常量。SourceManager是我自己定义的专门获取图片的类。IColorConstants是我自己定义的颜色的常量。给打加分享下，为了更清晰的看到每个属性设置的效果，最好跟每一层的Composite设置背景色。
  
  // 第一层
  final Composite composite1 = new Composite(parent, SWT.NONE);
  // 网格布局对象
  GridLayout gridLayout1 = new GridLayout(5, false);// 第一层网格5列
  GridData gridData1 = new GridData();
  gridData1.horizontalAlignment = GridData.FILL;//水平方向填充，但不会随着窗体的大小的变化而变化
  gridData1.verticalAlignment = GridData.FILL;//垂直方向填充，但不会随着窗体的大小的变化而变化
  gridData1.grabExcessVerticalSpace = true;  //这里是指定可以随着窗体的变化，在垂直方向上自动填充
  // 设置网格中子控件的水平间距
  gridLayout1.horizontalSpacing = 0;
  // 设置网格中子控件的垂直间距
  gridLayout1.verticalSpacing = 0;
  composite1.setLayoutData(gridData1);
  composite1.setLayout(gridLayout1);

 这是效果图：希望对大家有帮助，我会继续对RCP的布局和美化，做不断的分享，希望大家多多指教。
