CheckButtons are like Toggles in toggling their state when pressed.
However, they show an ok-marker if on; nothing if off.
CheckButtons are mostly used as part of a checkBox (since normally,
you want to have some label along the check) and often grouped for
many-in-many or one-in-many setups.
[StyleSheet values:]
checkToggleCheckColor <Color> color to draw check-image with.
defaults to value of #buttonActiveForegroundColor.
checkToggleActiveBackgroundColor background color to draw active checki-image with
checkToggleForegroundColor foreground color to use if off
checkToggleBackgroundColor background color to use if off
checkToggleBitmapFile <String> name of bitmap file for check-image
checkToggleStyle <Symbol> default checkForm style.
used if above is nil or file not readable
can be #cross or #check; defaults to #check
checkToggleAvtiveLevel <Number> active level - defaults to value of #buttonPassiveLevel
checkTogglePassiveLevel <Number> active level - defaults to value of #buttonPassiveLevel
checkToggleBorderWidth <Number> borderWidth - defaults buttons default
(if not set in the styleSheet, Toggle values are taken)

checkToggle alone:
[exBegin]
|top check|
top := StandardSystemView new.
top extent:100@100.
check := CheckToggle in:top.
check origin:10@10.
top open
[exEnd]
give it an action:
[exBegin]
|top check|
top := StandardSystemView new.
top extent:100@100.
check := CheckToggle in:top.
check origin:10@10.
check action:[:value | Transcript showCR:'changed to: ' , value printString].
top open
[exEnd]
give it a model:
[exBegin]
|top check model|
model := false asValue.
top := StandardSystemView new.
top extent:100@100.
check := CheckToggle in:top.
check origin:10@10.
check model:model.
top openModal.
Transcript showCR:'value after closing box: ' , model value printString
[exEnd]
multiple checks on a single model (with different change selectors):
(using a checkBox here, for the demonstration ...)
(this is a typical many-in-many setup)
[exBegin]
|top model panel ext1 ext2
readFlag writeFlag executeFlag|
readFlag := writeFlag := true.
executeFlag := false.
model := Plug new.
model respondTo:#read with:[readFlag].
model respondTo:#write with:[writeFlag].

model respondTo:#read: with:[:val | readFlag := val].
model respondTo:#write: with:[:val | writeFlag := val].
model respondTo:#execute: with:[:val | executeFlag := val].
top := StandardSystemView new.
top extent:200@200.
top label:'File permissions:'.
panel := VerticalPanelView origin:0.0@0.0 corner:1.0@1.0 in:top.
panel horizontalLayout:#leftSpace.
#(read write execute) do:[:sym |
|check|
check := CheckBox in:panel.
check label:sym.
check model:model; aspect:sym; changeMessage:(sym , ':') asSymbol.
].
top openModal.
Transcript showCR:'settings after closing box:'.
Transcript showCR:' read -> ' , readFlag printString.
Transcript showCR:' write -> ' , writeFlag printString.
Transcript showCR:' execute -> ' , executeFlag printString.
[exEnd]
checkToggles in a group - now, they have RadioButton behavior.
(this is a typical one-in-many setup)
[exBegin]
|top panel check1 check2 check3 grp|
top := StandardSystemView new.
top extent:200@300.
panel := VerticalPanelView origin:0.0@0.0 corner:1.0@1.0 in:top.
check1 := CheckToggle in:panel.
check2 := CheckToggle in:panel.
check3 := CheckToggle in:panel.
grp := RadioButtonGroup new.
grp add:check1.
grp add:check2.
grp add:check3.
top open
[exEnd]
Channel operation
-----------------
enabling other toggles via a toggle
[exBegin]
|top panel t enableChannel|
top := StandardSystemView new.
top extent:(400 @ 200).
panel := HorizontalPanelView origin:0.0@0.0 corner:1.0@1.0 in:top.
enableChannel := false asValue.
1 to:10 do:[:i |
t := CheckToggle in:panel.
t enableChannel:enableChannel.
].
t := Toggle in:panel.
t activeLogo:'enabled'; passiveLogo:'disabled'.
t pressChannel:enableChannel.
