【问题描述】：
我正在创建一个 GUI，我需要将不同的文件拖放到不同的 wxFilePicker 控件中。 基于此示例wxPython: Dragging a file into window to get file path 我能够将文件路径从一个文件获取到一个文件选择器或所有文件选择器的相同文件路径：
def updateText(self, text):
"""
Write text to the wx control
"""
self.m_filePicker1.SetPath(text)
self.m_filePicker2.SetPath(text)
self.m_filePicker3.SetPath(text)
尽管它按预期工作，但该解决方案没有用。
我需要为每个 wxfilepicker 控件创建不同的面板还是有其他方法可以解决这个问题？
提前谢谢你
伊沃

我认为您最好使用几个 TreeCtrls 或其他类似树的小部件之一。它们支持拖放比使用文件选择器小部件更容易。
