本文整理了Java中org.eclipse.swt.widgets.Tree.getColumn()方法的一些代码示例，展示了Tree.getColumn()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.getColumn()方法的具体详情如下：
包路径：org.eclipse.swt.widgets.Tree
类名称：Tree
方法名：getColumn

Tree.getColumn介绍

[英]Returns the column at the given, zero-relative index in the receiver. Throws an exception if the index is out of range. Columns are returned in the order that they were created. If no TreeColumns were created by the programmer, this method will throw ERROR_INVALID_RANGE despite the fact that a single column of data may be visible in the tree. This occurs when the programmer uses the tree like a list, adding items but never creating a column.
[中]返回接收器中给定的零相对索引处的列。如果索引超出范围，则引发异常。列将按创建顺序返回。如果程序员没有创建TreeColumn，尽管树中可能有一列数据可见，此方法仍将抛出ERROR_INVALID_RANGE。当程序员像列表一样使用树，添加项目，但从不创建列时，就会发生这种情况。

protected void setSort( int i ) {
 if ( sortColumn == i ) {
  ascending = !ascending;
 } else {
  sortColumn = i;
  ascending = true;
 }
 if ( sortColumn >= 0 && sortColumn < 5 ) {
  TreeColumn column = wTree.getColumn( sortColumn );
  wTree.setSortColumn( column );
  wTree.setSortDirection( ascending ? SWT.UP : SWT.DOWN );
 }
 refreshTree();
}

public static final void setOptimalWidthOnColumns( Tree tree ) {
 int nrCols = tree.getColumnCount();
 int[] max = new int[nrCols];
 Image image = new Image( tree.getDisplay(), 10, 10 );
 GC gc = new GC( image );
 for ( int i = 0; i < max.length; i++ ) {
  TreeColumn treeColumn = tree.getColumn( i );
  Point point = gc.textExtent( treeColumn.getText() );
  max[i] = point.x;
 }
 getMaxWidths( tree.getItems(), max, gc );
 gc.dispose();
 image.dispose();
 for ( int i = 0; i < max.length; i++ ) {
  TreeColumn treeColumn = tree.getColumn( i );
  treeColumn.setWidth( max[i] + 30 );
 }
}
