Gray Out Parameters of an Operator in the F6 Menu

Coding Python Support
#1

Hi
I’m trying to get my ARewO to be a GUI addon.
I’m getting good progress, but 2 questions remain:

  1. If no Armature is selected, I’d like to gray out (removed, but preferably grayed out) the checkbox for “use armature” in the F6 or T-menu

  2. (more for convenience) I hope this is possible
    I’d like to create an object select list to select the object for the world location of the duplicates - also in the menu after you pressed run
    Thanks

in the draw() method of your panel or operator, you can do e.g.:

col = layout.column()
col.enabled = 'ARMATURE' in (ob.type for ob in context.selected_objects)

# if property is declared as bpy.types.Scee.the_prop = bpy.props.*()
col.prop(context.scene, "the_prop")

# if it's an operator property
col.prop(self, "the_prop")

There’s also an .active property for layout elements (layout, column, row, …), which will gray the property out, but still allow for user input in that mode.

Dankeschön.
