Correct code for: set Snap to Pixel = True/False as Pie menu in UVEditor

Question

I try to figure out how via a pie command one could set the "Snap to Pixel" = true or false inside the UV editor and struggle with finding the right way to write this as a code instruction. For the pie menu I would like to have a button to press and each press can trigger either the true or false based on the current state which I think one could check via an if step. Right?

As it seems the console reads this out:

But unfortunately this is the same when selecting "Constraint to Image Bounds".

The command I think is:

spaceUVEditor.use_snap_to_pixels

And this being boolean so true or false.

Answer 1

You can use wm.context_set_boolean or wm.context_toggle to achieve this.

The code should look like this:

op_props = pie.operator("wm.context_set_boolean", text="Snap to pixels")
op_props.data_path = "space_data.uv_editor.use_snap_to_pixels"
op_props.value = True

#or

pie.operator("wm.context_toggle", text="Snap to Pixels").data_path = (
    "space_data.uv_editor.use_snap_to_pixels")

Answer 2

you have to find the UV editor area to access this property, add the following inside the pie menu :

    for area in bpy.context.screen.areas: #loop through areas
        if area.type == 'IMAGE_EDITOR':   #find the image editor
            space_data = area.spaces.active
            pie.prop(space_data.uv_editor,"use_snap_to_pixels") #the uv editor is part of the image editor
