I'm trying to get a horizontal scale with

• origin on the left
• cursor keys left/right = decrease/increase
• cursor keys up/down = increase/decrease (and the same for pageup/pagedown/end/home)

setInverted(true) doesn't help much because then I get the origin to the right. Would I have to intercept/override some key events to do this?

import std.stdio;

import gtk.Main;
import gtk.MainWindow;
import gtk.Box;
import gtk.Scale;

void main(string[] args)
{
	Main.init(args);

	MainWindow window = new MainWindow("title");
	window.setSizeRequest(400, 200);
	Box box = new Box(Orientation.VERTICAL, 5);
	{
		// ✓ origin left
		// ✓ left/right cursor keys
		// ✕ up/down cursor keys
		Scale scale1 = new Scale(GtkOrientation.HORIZONTAL, 0, 100, 10);
		box.add(scale1);

		// ✕ origin left
		// ✓ left/right cursor keys
		// ✓ up/down cursor keys
		Scale scale2 = new Scale(GtkOrientation.HORIZONTAL, 0, 100, 10);
		scale2.setInverted(true);
		box.add(scale2);
	}
	window.add(box);

	window.showAll();
	Main.run();

}
