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

Tree.getColumns介绍

[英]Returns an array of TreeColumns which are the columns in the receiver. Columns are returned in the order that they were created. If no TreeColumns were created by the programmer, the array is empty, despite the fact that visually, one column of items may be visible. This occurs when the programmer uses the tree like a list, adding items but never creating a column.

Note: This is not the actual structure used by the receiver to maintain its list of items, so modifying the array will not affect the receiver.
[中]返回TreeColumn的数组，它们是接收器中的列。列将按创建顺序返回。如果程序员没有创建TreeColumns，则数组是空的，尽管在视觉上，一列项目可能是可见的。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。
注意：这不是接收方维护其项目列表所使用的实际结构，因此修改数组不会影响接收方。
