Hi Patrick,
Try this...
view layout [
b: button "Font Test" font [name: "Arial" size: 12]
button "Change" [
b/font/name: "Times"
b/font/size: 18
show b
]
]
You can see the font object by using probe like so...
>> probe b/font
make object! [
name: "Times"
style: 'bold
size: 18
color: 255.255.255
offset: 2x2
space: 0x0
align: 'center
valign: 'middle
shadow: 1x1
colors: [255.255.255 255.180.55]
]
Carl.
