Can't Change Directories

Coding Python Support
1

I’ve been working on a Google Image search experiment and I’m stuck.

When the button gets clicked, it should trigger the file browser to go to a special directory. I can get the directory to show up in the directory field. What I can’t seem to do is get the directory view to update.

How do I do this? Here’s the code so far?


import bpy
import pdb
# goobr_header.py


class GoobrHeader( bpy.types.Header ):
    
    bl_space_type = "FILE_BROWSER"

    def draw( self, context ):
        layout = self.layout
        scn = bpy.context.scene
        col = layout.column()
        split = col.split( percentage=0.5 )
        colL = split.column()
        colR = split.column()
        colL.prop( scn, "searchTerm" )
        colR.operator( "goobr_op" )

class GoobrOp( bpy.types.Operator ):

    bl_idname = "goobr_op"
    bl_label = "Get Google Images"

    def execute( self, context ):
        print( "test stub of execute for goobr op" )
        fileSpace = context.space_data
        fileSpace.params.directory = "/home/username/testdir/"
        
        pdb.set_trace()
        return { 'FINISHED',}



def register():
    scn = bpy.types.Scene
    scn.searchTerm = bpy.props.StringProperty( name = "search term", description = "Search term used to google for images.", default = "" )

def unregister():
    pass

if __name__ == "__main__":
    register()
