Drag & Drop-Dateien zu verschiedenen WxFilePicker-Steuerelementen

Question

Ich erstelle eine GUI, wo ich verschiedene Dateien in verschiedene wxFilePicker Steuerelemente ziehen und ablegen muss. Basierend auf diesem Beispiel wxPython: Dragging a file into window to get file path konnte ich die Filepath von einer Datei in eine Filepicker oder gleichen filepath für alle filepickers erhalten mit:

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) 

Obwohl es, wie es funktionierte diese Lösung zu erwarten wäre es nicht sinnvoll.

Muss ich für jedes wxfilepicker-Steuerelement verschiedene Bedienfelder erstellen oder gibt es eine andere Möglichkeit, dieses Problem zu lösen?

Vielen Dank im Voraus

Ivo
