Re: [pygame] Layout module for Pygame surfaces

[Jake b <ninmonkeys@xxxxxxxxx>]

I have felt the same, thinking back to handling xml in the past. I was thinking that you draw a SVG in inkscape, which xml is read for python UI.

It looks like its a pythonic way if you need xml, but I've only used it in small protos. I'm curious if anyone has used "amara" in bigger projects?

(Not 
saying specifically this project, for anything.)

http://www.xml3k.org/Amara/QuickRef [ link to amara1.0  quickref, since 2.0 

if curious: random snippit, using ETree vs amara.

Here's something I whipped up. Loads window containing list of buttons.

    xml_ui = """

    <button type="ok" text="save" selected="true">

    import amara

    win.widgets = []
    win.text, win.type = doc.window.text, doc.window.type
    
    for cur in doc.window.button:
        b = Button()
        b.rect = pygame.Rect( int(cur.loc.x), int(cur.loc.y), int(cur.loc.w), int(cur.loc.h))
