将文件拖放到不同的WxFilePicker控件

时间：2017-11-14 11:02:33

标签： python user-interface drag-and-drop wxpython

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)

虽然它起作用，但预计该解决方案无用。

我是否需要为每个wxfilepicker控件创建不同的面板，还是有另一种方法可以解决此问题？

提前谢谢
