This script is a simple introduction to Panels and Operators using Blender Python scripting. The following description hopefully fulfills it's purpose (to describe).

== Code ==

<source lang="python">
import bpy

class OBJECT_PT_pingpong(bpy.types.Panel):
bl_label = "Ping Pong"
bl_space_type = "PROPERTIES"
bl_region_type = "WINDOW"
bl_context = "object"

is_left = True

def draw_header(self, context):
layout = self.layout
layout.label(text="", icon="PHYSICS")

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

row = layout.row()
split = row.split(percentage=0.5)
col_left = split.column()
col_right = split.column()

if self.is_left:
col_left.operator("object.pingpong", text="Ping")
else:
col_right.operator("object.pingpong", text="Pong")

class OBJECT_OT_pingpong(bpy.types.Operator):
bl_label = "Ping Pong Operator"
bl_idname = "object.pingpong"
bl_description = "Move the ball"

def execute(self, context):
OBJECT_PT_pingpong.is_left = not OBJECT_PT_pingpong.is_left
self.report({'INFO'}, "Moving the ball")
return {'FINISHED'}

def register():
bpy.utils.register_module(__name__)

def unregister():
bpy.utils.unregister_module(__name__)

if __name__ == "__main__":
register()
</source>

== Description ==

=== OBJECT_PT_pingpong ===

The OBJECT_PT_pingpong class is to draw the gui (it is a Panel subclass).

; ''bl_space_type''
: is the kind of space it shows up. Here it's the Properties Editor (<code>'PROPERTIES'</code>).
; ''bl_region_type''
: is the kind of region it shows up in. <code>'WINDOW'</code> is the main region of every area / space type.
; ''bl_context''
: is when the panel will show (so you will need to have an object selected, for the panel to show up). The combination of the space type <code>'PROPERTIES'</code> and the context <code>'object'</code> will show the panel in the Object tab of the Properties Editor.
; ''bl_label''
: is the text displayed in the header.
; ''is_left''
: is a custom class variable which we use to determine which button needs to be displayed.
; ''draw_header()''
: is used to draw extra things in the header. In our case an icon. You can also use it to draw a checkbox that enables or disables all the settings in the panel (the actual action / state change it not handled here however).
; ''draw()''
: defines the visual elements of the panel. There is a single row, which is split in half. Each half contains a column. Additionally we draw a button in one of these columns. The 'is_left' variable determines which one we draw. These buttons refer to an operator called <code>object.pingpong</code>, which is the ''bl_idname'' of the next class.

=== OBJECT_OT_pingpong ===

The OBJECT_OT_pingpong class defines our custom operator.

; ''bl_label''
: is the default text that's used by buttons in the user-interface (which we overwrite by for instance: text="Ping" )
; ''bl_idname''
: is what we use to refer to this operator.
; ''bl_description''
: is the text that shows up when you hover over a button that calls this operator (a tooltip).
; ''execute()''
: is called whenever a button of this operator is clicked.
; ''report()''
: displays a message in the main header of Blender. After this line we also set the 'is_left' variable to the other value.
