本文整理了Java中org.eclipse.swt.widgets.Tree.getHeaderHeight()方法的一些代码示例，展示了Tree.getHeaderHeight()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Tree.getHeaderHeight()方法的具体详情如下：
包路径：org.eclipse.swt.widgets.Tree
类名称：Tree
方法名：getHeaderHeight

Tree.getHeaderHeight介绍

[英]Returns the height of the receiver's header
[中]返回接收器标题的高度

代码示例

@Override
protected boolean allowMouseEvent( Tree tree, int x, int y ) {
 return super.allowMouseEvent( tree, x, y ) && y >= tree.getHeaderHeight();
}

private static void writeHeaderHeight( final Tree tree ) throws IOException {
 JSWriter writer = JSWriter.getWriterFor( tree );
 Integer newValue = new Integer( tree.getHeaderHeight() );
 writer.set( PROP_HEADER_HEIGHT, "headerHeight", newValue, null );
}

final int getVisibleRowCount( boolean includePartlyVisible ) {
 int clientHeight = getClientArea().height - getHeaderHeight();

  int itemHeight = getItemHeight();
  result = clientHeight / itemHeight;
  if( includePartlyVisible && clientHeight % itemHeight != 0 ) {
   result++;
  }
 }
 return result;
}

}
