How do you rotate the gtk widget?

Question

Let's say that the widget is a VBox containing a label and two buttons.

In addition, suppose that the desired degree of rotation is 90 °.

How can it be rotated? I don't think this is possible by default, but I think it is possible.

However, I have no idea how to start. Am I writing my own widget? What am I doing subclass?

Answer 1

You can fake it like this:

label.set_angle(90)
button1.get_child().set_angle(90) # assuming it not a stock button
button2.get_child().set_angle(90)
vbox.set_orientation(gtk.ORIENTATION_HORIZONTAL)

Answer 2

First, if your widget does not have its own X window (VBox does not), place it inside the EventBox.
