How to place a checkbox into 3dView Header

Question

I wrote a simple script to quickly (by hotkey) change Object Origin transformation options, but I want a good indication that this is enabled or disabled, and the most better way is to add a checkbox to a 3DView header, near with Options dropdown - see the fake shot. Spend a lot of time how to add it to it, but no luck! ((

#todo: Make it as a checkbox in Header
bl_info = {
    "name": "PivotToggle",
    "author": "MikeMS",
    "version": (1,0),
    "blender": (2,93,0),
    "category": "Object",
    "location": "Add to QuickFavorites from Search Operator or to a Hotkey for object.pivottoggle",
    "description": "Toggle Affect Only Origins and Parent for Object transformations.",
}
import bpy
class PivotToggle(bpy.types.Operator):
    """Toggle Affect Only Origins and Parent for Object transformations."""
    bl_idname = "object.pivottoggle"
    bl_label = "PivotToggle"
def execute(self, context):

    #Script start: 

    if bpy.context.scene.tool_settings.use_transform_data_origin == False and bpy.context.scene.tool_settings.use_transform_skip_children == False:
        bpy.context.scene.tool_settings.use_transform_data_origin = True
        bpy.context.scene.tool_settings.use_transform_skip_children = True
        self.report({'INFO'}, &quot;Pivot Transformation Enabled&quot;)
    else:
        bpy.context.scene.tool_settings.use_transform_data_origin = False
        bpy.context.scene.tool_settings.use_transform_skip_children = False
        self.report({'INFO'}, &quot;Pivot Transformation Disabled&quot;)


    #Script end.

    return {'FINISHED'}



def register():
    bpy.utils.register_class(PivotToggle)
def unregister():
    bpy.utils.unregister_class(PivotToggle)
if name == "main":
    register()

Thanks for a help!

This question is similar, but you need to adapt to the 3D Viewport instead of the outliner. This manual entry is the starting point for searching for the right place. — Marty Fouts, Oct 22 '21 at 14:11

        row.prop(tool_settings, "use_transform_data_origin", text="Origins")

def register():
    bpy.utils.register_class(OBJECT_OT_pivot_toggle)
    bpy.types.VIEW3D_HT_header.append(origin)

def unregister():

if __name__ == "__main__":

I think you want to remove _tool from your append and remove routines, as the OP wants the question in the view header. I hope you don't mind that I did that. — Marty Fouts, Oct 22 '21 at 15:35
Hmm, strange, by checking this checkbox enables only origins (not both origins and parents options), I need to understand it better how it works...)) P.S.: Oh, yep, I understand why it's that)... Thanks) — MikeMS, Oct 22 '21 at 15:50
@MikeMS don't leave us hanging. What did you have to change to get it to work? — Marty Fouts, Oct 22 '21 at 16:36
@marty-fouts It's all fine. But I returned return {'FINISHED'} because without it hotkey starts to throw an error about incorrect return value and stops working. — MikeMS, Oct 22 '21 at 16:45
doh. I missed that that had gone missing when I made my small change. Fixed. — Marty Fouts, Oct 22 '21 at 16:47
