GIMP 3/ Python3 how to use Switch instead of checkbuttons (original) (raw)

The docs here

say we can use aswitch instead of acheckbuttons.
How can I do it ?

The docs you point out lists all the available types (depending on argument type), and as you see, GTK_TYPE_SWITCH is indeed supported. Just use it for the last argument.

As for using a GType in the Python binding, this was already explained to you here: GIMP3/Python3 Sliders instead of spinners? - #2 by JimDee2

It’s the same thing here, except that it will be Gtk.Switch.__gtype__ in this case.

If I do

toggle = dialog.get_widget("yes_no", GimpUi.Switch)

similar to what I did with the other widgets
GIMP tells me:
AttributeError: ‘gi.repository.GimpUi’ object has no attribute ‘Switch’

So that can’t be it. What am I doing wrong?

Hi! We don’t have a GimpUi type for switch, so like @Jehan said, you’ll want to use the generic GTK type. I just tried this and it worked fine.

toggle = dialog.get_widget("yes_no", Gtk.Switch.gtype)

This again told me:
AttributeError: type object ‘Switch’ has no attribute ‘gtype’

But it works like this here:
toggle = dialog.get_widget("yes_no", Gtk.Switch)

Some things are not self explanatory for people without C programming experience …

Odd, it worked fine for me - perhaps we have different versions of Python? Oh well - glad you got it working!

Isn’t the “gtype” supposed to have double underscores each side? I think this is a Python but not C thing. It is a pygobject binding specific field used to report the GType of a class. What is expected in dialog.get_widget is a Gtype not an object.

Oh yes, you’re right.
And then it works …

The forum just swallowed the underscores if there have been any.
I just copied @CmykStudent’s code, forgot about the underscores seen in my other question’s answer. My bad.

Why does it also work without the gtype thing?

Probably some pygobject magic which converts things automatically.
