CDPanel: CEDAR DEFINITIONS =
BEGIN
Control panels for the display and modification of values by the interactive user.
Don't use define procedures from forked process! (order gets fooled).
Create:
PROC [design:
CD.Design]
RETURNS [ViewerClasses.Viewer];
--Creates a control panel panel.
--Only one panel-viewer per design is created;
--If panel-viewer already exists, simply returns it.
Line:
PROC [tech:
CD.Technology ←
NIL];
--Use a new line for the next feature.
Layer:
PROC [layer:
CD.Layer, text: Rope.
ROPE, min, default:
CD.Number ← 1, option:
NAT ← 0, tech:
CD.Technology ←
NIL];
--Defines a layer entry in control panel.
--Only layers of technology tech may be used.
--Use CDLayers to querry or update values; display is updated automatically.
Info:
TYPE =
RECORD [
text: Rope.ROPE ← NIL,
cdValueKey: REF ← NIL, redisplay: BOOL ← FALSE,
width: INT ← -1, space: INT ← -1,
xpos: INT ← -1, maxx: INT ← -1,
border: BOOL ← FALSE
];
--cdValueKey must have been correctly registered with CDValue! CDPanel does NOT itself.
--(allows hooking entries onto already used keys).
Number:
PROC [button: Info, number: Info, min:
INT ←
FIRST[
INT], max:
INT ←
LAST[
INT], default:
INT ← 0, lambda:
INT ← 1, tech:
CD.Technology ←
NIL];
--Defines a number entry in control panel.
--Displayed value does not follow changes of CDValue.StoreInt; but redisplay works.
--lambda=0: use lambda of technology.
--Restriction: button.cdValueKey, number.text must be NIL.
Button:
PROC [button: Info, proc: CDSequencer.CommandProc ←
NIL, command:
ATOM ←
NIL, data:
REF ←
NIL, queue: CDSequencer.QueueMethod ← useDefault, topLine:
BOOL ←
FALSE, tech:
CD.Technology ←
NIL];
--Defines a button in control panel.
--The button is always forked.
--data is hanged on comm.data.
Label:
PROC [label: Info
, tech:
CD.Technology ←
NIL];
--Defines a label in control panel.
Text:
PROC [button: Info, text: Info, editable:
BOOL ←
TRUE, tech:
CD.Technology ←
NIL];
--Defines a rope entry in control panel.
--cdValue on design typical a ROPE; technology may have LIST OF ROPE.
--Usually it is bad to set rope.redisplay to true: user edited text may get lost.
--Restriction: button.cdValueKey must be NIL.
TakeDownText:
PROC [design:
CD.Design, cdValueKey:
REF]
RETURNS [rope: Rope.
ROPE];
--Shortcut for text entries.
--Takes the displayed rope, stores it using CDValue.Store, and also returns it.
PutUpText:
PROC [design:
CD.Design, cdValueKey:
REF, rope: Rope.
ROPE];
--Shortcut for text entries.
--Takes the given rope, stores it using CDValue.Store and updates the display on the panel.
TakeDown:
PROC [design:
CD.Design, cdValueKey:
REF]
RETURNS [
REF];
--Takes any displayed entry, stores it using CDValue.Store, and, also returns it.
PutUp:
PROC [design:
CD.Design, cdValueKey:
REF]
RETURNS [
REF];
--Fetches value using CDValue.Fetch, returns it, and,
--puts it into the display if redisplay flag is true.
PutUpAll:
PROC [design:
CD.Design];
--Fetches with CDValue and update display for all entries for which redisplay is true.
END.
