Events 事件函数'；wxpython4.01/Python 3.7中的s值

对不起我的愚蠢。。。 所以我上传了完整的代码

请教我正确的方法

在组合框中，我选择一个内容 它绑定到函数“def OnSelectComboBox（self，event）：” 我想在以下位置获取combobox的选定内容： *****“我想在此处获取选定的组合框内容”****位置 但我不能

所以请告诉我这是不可能的还是另一种方式

谢谢

传递给事件处理程序函数的事件参数包括一个

GetSelection

方法，该方法可用于获取所选项目的索引，以及一个

GetString

方法，用于获取该项目的标签。

谢谢Robin（你回答我愚蠢的问题时真的很惊讶……）真的很感谢上面位置a的代码，我想捕捉combobox的跨越。当然要使用GetSelection和GetString，但结果总是-1。。。。带有事件和事件函数combobox的combobox绑定combobox event可以捕获combobox的字符串和选择，但我想（如果可能的话）在位置a获取combobox选择的值，这可能吗？这可能是个愚蠢的问题，但我至少考虑了2周。（：-（）发布您的代码，而不是对其进行解释。对不起，萨克森州的Rolf，我很笨……您是否尝试过

print（event.GetString（））

它会起作用。我怀疑您的问题可能与您的sqlite3选择或以下代码有关。
