a frame around something. The frame may have a label, whose position
|
|
133
|
55 |
is controlled by the labelPosition variable, a symbol which may be one of:
|
|
38
|
56 |
[#topCenter #topLeft #topRight #bottomLeft #bottomCenter #bottomRight]
|
|
|
57 |
|
|
133
|
58 |
The default labelPosition is controlled by the styleSheet variable:
|
|
|
59 |
'framedBoxLabelPosition' (usually, #topCenter).
|
|
|
60 |
|
|
38
|
61 |
Its also possible, to not show the frame but only the label, by setting
|
|
|
62 |
showFrame to false.
