[wxPython-users] Showing specificed images in ThumbnailCtrl, not from a folder but from a list of files

[Gavana, Andrea]

Hello Thomas,

	sorry for the late reply, holiday time :-)

You should look at the ShowDir and/or ListDirectory methods in ThumbnailCtrl. You can easily modify them to do whatever you want. At the moment, these methods just load all the files from a specified directory, but it's not very hard to change this behaviour:

    def ShowDir(self, dir, filter=THUMB_FILTER_IMAGES):
        """ Shows Thumbnails For A Particular Folder. """
        
        self._dir = dir
        if filter >= 0:
            self._filter = filter
            
        self.SetCaption(self._dir)
        
        self._isrunning = False

        self._parent.RecreateComboBox(dir)
        
        # update items
        self._items = []

        # ==> CHANGE HERE <==
        filenames = self.ListDirectory(self._dir, extensions)

        myfiles = []
	  ...

Andrea.
