13.03.12 bl_context and poll

http://www.blender.org/documentation/blender_python_api_2_62_0/bpy.types.Panel.html

I did this with the bl_space_type 'VIEW_3D'.

This is a header for a Panel type.

class bpy.types.Panel(bpy_struct):
    bl_space_type = 'VIEW_3D'                   # Space Type: 'VIEW_3D'
    bl_region_type = 'TOOLS'                    # Region Type: 'TOOLS', 'UI'
    bl_context = 'objectmode'                   # 'TOOLS' 3D View Mode: 'objectmode', 'mesh_edit'
    bl_label = 'Tools'                          # Panel Name: 'Tools', 'My Panel'
    
    @classmethod
    def poll(cls, context):                     # poll
        return ((context.mode == 'OBJECT'))	# 'UI' 3D View Mode: 'OBJECT', 'EDIT_MESH'

Before the Panel is drawn, it has methods to check if the context is correct.

DRAW_PANELS:
	if poll():                              # (context.mode == 'EDIT_MESH')
		DRAW_PANEL()

The "Tools" Region 'TOOLS' uses bl_context.

The "Properties" Region 'UI' uses the return of poll:

    bl_context
        'objectmode'
        'mesh_edit'
        'armature_edit'
        'posemode'
        
    bpy.context.mode
        'OBJECT'
        'EDIT_MESH'
        'EDIT_ARMATURE'
        'POSE'
