Question

我的ObjectListView中的一列包含的数据太长而无法完全显示，因此会自动截断。我想要一种方法来显示单元格中的所有数据。我已经在this tutorial中实现了这个建议，但我对结果不是很满意，因为工具提示是针对整个列表的，而不仅仅是列表项。理想情况下，我想在this other question的第一张图片中找到完全相同的内容。

那篇文章提到悬浮扩张行为是自动发生的，但我没有看到任何重建这种行为的方法。也许它只发生在Windows上？我正在使用GTK。

Answer 1

您可以随时实现一个右键单击弹出窗口，您可以使用您想要的任何内容填充 - 请参阅弹出窗口的wxPython演示作为起点。

或者你可以从ObjectListView切换到wx.lib.agw.UltimateListCtrl或DataViewControl - 这两个似乎都支持工具提示，这些工具提示知道你正在悬停的行和列。

我使用您提到的tutorial在answer中使用了代码，并提出了以下内容：

from ObjectListView import ObjectListView, ColumnDefn

我还更新了我的教程以包含上面的代码。请注意，只有在鼠标浏览第一列中的单元格时，工具提示才会更新。我没有找到一个很好的方法。
