When declaring a panel, what does the 'bl_context' value need to be?

Question

I'm confused about how to declare a panel.

I've tried to write a simple panel but it doesn't work:

class TestPanel(bpy.types.Panel):
    bl_idname = "object.test"
    bl_label = "test"
    bl_space_type = 'VIEW_3D'
    bl_region_type = 'TOOLS'
    bl_context = 'sculptmode'
    bl_category = "test"

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

I would like which values can be used in bl_context

In you specific case, the bl_context you are looking for is sculpt_mode. There are many others including:

• objectmode
• mesh_edit
• curve_edit
• surface_edit
• text_edit
• armature_edit
• mball_edit
• lattice_edit
• pose_mode
• imagepaint
• weightpaint
• vertexpaint
• particlemode
