For now, set actions etc. via sends to the components,
labelView and toggleView.

examples
"
no-op checkBox:
|b|
b := CheckBox new.
b label:'foo'.
b open
changing colors (a demo only: it is no good style to fight the styleSheet):
|panel b|
panel := VerticalPanelView new.
b := CheckBox in:panel.
b label:'foo'.
b := CheckBox in:panel.
b label:'bar'.
b labelView foregroundColor:Color red.
b := CheckBox in:panel.
b label:'baz'.
b toggleView activeForegroundColor:Color blue.
panel open
using action-blocks:
|b|
b := CheckBox new.
b label:'check'.
b action:[:value | Transcript show:'set to: '; showCr:value].
b open.
with a model (default ST-80 behavior, sending #value: to the model):
(see changing value in the inspector)
|b model|
model := ValueHolder newBoolean.
b := CheckBox new.
b label:'check'.
b model:model.
b open.
model inspect.
with a model and different changeSelector
(using a plug here, for demonstration only):
|b model|
model := Plug new.
model respondTo:#changeCheck: with:[:arg | Transcript showCr:'change to ' , arg printString].
b := CheckBox new.
b label:'check'.
b model:model; change:#changeCheck:.
b open.
multiple checkBoxes on a single model (using different aspects)
|top panel b model value1 value2 ok|
value1 := true.
value2 := false.
model := Plug new.
model respondTo:#value1 with:[value1].
model respondTo:#value1: with:[:val | value1 := val].
model respondTo:#value2 with:[value2].
model respondTo:#value2: with:[:val | value2 := val].
top := DialogBox new.
top extent:200@300.
panel := VerticalPanelView new.
b := CheckBox in:panel.
b label:'check1'.
b model:model; aspect:#value1; change:#value1:.
b := CheckBox in:panel.
b label:'check2'.
b model:model; aspect:#value2; change:#value2:.
top addComponent:panel.
top addAbortButton; addOkButton.
top okAction:[ok := true].
ok := false.
top openModal.
ok ifTrue:[
Transcript show:'value1: '; showCr:model value1.
Transcript show:'value2: '; showCr:model value2.
