use Gtk (*)

app = application("No Frame")
win = window(app.name)
win.set_decorated(false)  <--
win.show_all
app.main

use Gtk (*)

app = application("Change Pix")
win = window(app.name)
win.set_default_size(400,400)

panel = vbox()
win.add(panel)

img1 = image('tweety_e0.gif')
img2 = image('qu.gif') 

panel.add([img1,img2])

btn = toggle_button('Swap') btn.connect('clicked',@change)
panel.pack_end(btn)

win.show_all
img2.hide
app.main

sub change(x:Int)->Int  # swaps images when button toggled
switch btn.get_active 
      case true  img1.hide img2.show break
      case false img2.hide img1.show break

return 0;;

use Gtk (*)

app = application("Change")
win = window(app.name)
win.set_default_size(400,400)

panel = vbox()
win.add(panel)

lbl1 = label('Label One')
lbl1.modify_font('Courier 16')   # one way

lbl2 = label("<b>Bold</b> and <i>Italic</i>")  # another way (pango markup)

panel.add([lbl1,lbl2])

win.show_all
app.main
