Question

我正在使用grid几何管理器创建一个包含以下小部件结构的表：

第0列和第1列中的Radiobuttons
第2列中的水平可滚动文本（表示可能很长的文件名）
和进度条（第3列的数值将在后面填写）。

这是可以横向滚动的Text给我带来麻烦。我尝试创建一个Listbox小部件，它位于第2列（作为整个框架的子级）并跨越所有行。这看起来很有希望，直到很明显列表框中的文本行与父网格的行不对齐。

我一直在寻找一种方法来填充列表框中的每一行文字，以便行匹配;但即使这是可能的，我宁愿选择更通用，更少克服的解决方案。

是否有一种简单的方法可以使单个列可滚动，而我却不知道？ setGrid是一个可能的解决方案吗？
