I think it's a stupid question and the answer may be right in front of my nose. I create a menu populated by the text_blocks of the Text Editor, asking which text I want.

Then.... how do I process the selection ?

Here's my menu :

class Choose_Text(bpy.types.Menu):
    bl_idname = "OBJECT_MT_select_file"
    bl_label = "Where is my text ?"

    def draw(self, context):
        layout = self.layout

        for i in bpy.data.texts:
            layout.operator("something", text=i.name)

I guess, all the menu items should lead to the same operator and transmit a variable, is that right ?

Thanks for any help !


The menu invokes an operator and this operator would need to receive the filename as a parameter.

I assembled a few lines (sorry for not renaming the classes) I'm sure this can be improved.

AnimMenu - iterates over all loaded text files and add them to a manu in the main header. The files name is handed over by a StringProperty.

AnimOperator - Is invoked when a menu item has been selected it reads the value of the property and shows how the filename is received and how to retrieve files content.

import bpy


class AnimOperator(bpy.types.Operator):
    bl_idname = "object.anim_operator"
    bl_label = "Pose Anim Operator"

    text_name = bpy.props.StringProperty(name="anim_text_name")
    def poll(cls, context):
        return context.active_object is not None

    def execute(self, context):
        print("invoked script %s" % text )
        print("invoked script name=%s" % self.text_name )
        txt = bpy.data.texts[ self.text_name ].as_string()
        print("do something with script")
        return {'FINISHED'}

class AnimMenu(bpy.types.Menu):
    bl_label = "Anim Menu"
    bl_idname = "OBJECT_MT_anim_menu"

    def draw(self, context):
        layout = self.layout
        for txt in bpy.data.texts:
            props = layout.operator("object.anim_operator", text=txt.name)
            props.text_name = txt.name

def draw_item(self, context):
    layout = self.layout

def register():

def unregister():

if __name__ == "__main__":
