Can someone explain why my booleans aren't showing up as checkboxes in my display panel (the panel shows up in the 3d view tools panel)?

Code:

what you do is checking for a certain scene:
bpy.context.scene['flipDirection']

and if it doesn't exist, you set this key to False: bpy.context.scene['flipDirection'] = False

but this won't create a BoolProperty type, but an int type.

If you wanna store a BoolProperty in a scene, you gotta add this prop to all scenes, like:
bpy.types.Scene.flipDirection = BoolProperty(...)

or if you need it temporarily only, create it inside of the panel class:

Code:

flipDirection = bpy.props.BoolProperty(...) def invoke(self, context, event):     try:         context.scene['flipDirection']         self.flipDirection = True     except KeyError:         self.flipDirection = False     # Might have to call parent's invoke here...     #return super().invoke(context, event) def draw(self, context):     layout = self.layout     layout.prop(self, "flipDirection", text="Flip Direction")

but i wonder what this is good for... What are you actually after?
