I'm making an add-on that is supposed to take in a lot of user-decided configurations . I know I can create panels and stuff, but I'd prefer to create a configuration window that pops up and fills the entire screen, since there are too many options to select, and I also have to show some image thumbnails.

This new window can have all my configuration options laid out in any way I want, and can take any size, and has a close button. It can be opened using some hotkey or button when the user wants to use my add on.

Is something like this possible?

    $\begingroup$ You could possibly create a separate program and run that from the blender add-on (os.system("some_executable.exe"). That program could have whatever interface you like (recommend PyQt for cross-platformness), and simply save the user's choices to a text file that the add-on then reads. But if most of the user's time is spent in blender using your tool, it'd be best if the entire interface is consistent and within blender. $\endgroup$

The design you propose is not very blender-like. The way this should be are options under the addon box in User Preferences > Addons. This is how you implement it:

import bpy

class SomeAddonPrefs(bpy.types.AddonPreferences):
    bl_idname = __name__
    # here you define the addons customizable props
    some_prop = bpy.props.FloatProperty(default=1.0)

    # here you specify how they are drawn
    def draw(self, context):
        layout = self.layout
        layout.prop(self, "some_prop")

# and this is how you access those settings in your add-on code
some_prop = bpy.context.user_preferences.addons[__name__].preferences.some_prop

#for 2.80 use
some_prop = bpy.context.preferences.addons[__name__].preferences.some_prop

# classes needs to be registered of course

Add-ons can have their own user preferences.


This doesn't fill the entire window, but this is the intended way for your add-on to be configured.
