a wrapper for a geometric object, which is to be drawn stroked.
This allows any geometric thingy to be used as a component in a view.
(background info: geometrics are mathematical objects - they do not
keep any color or lineStyle attributes. Wrappers add this information
and can also be used as components of a view)
Notice:
this class was implemented using protocol information
from alpha testers, from reading PD programs and
from the Hopkins/Horan book.
- it may not be complete or compatible to the corresponding ST-80 class.
If you encounter any incompatibilities, please forward a note
describing the incompatibility verbal (i.e. no code) to the ST/X team.

wrap an ellipticArc and display it
(notice, that no automatic redraw is performed):
[exBegin]
|v e component|
v := (StandardSystemView extent:250@250) openAndWait.
e := EllipticalArc boundingBox:(10@10 corner:90@90)
startAngle:0
sweepAngle:270.
component := StrokingWrapper on:e.
component displayOn:v.
[exEnd]
wrap a rectangle and an ellipticArc,
and add them as components to a View
(notice, that doing so makes the redraw automatic):
[exBegin]
|v e component|
v := StandardSystemView extent:250@250.
e := Rectangle origin:10@10 corner:90@90.
component := FillingWrapper on:e.
component foregroundColor:Color red.
v addComponent:component.
e := EllipticalArc boundingBox:(10@10 corner:90@90)
startAngle:0 sweepAngle:360.
component := StrokingWrapper on:e.
component lineWidth:5.
v addComponent:component.
v addComponent:(Button label:'hello').
v open
[exEnd]
with lineWidth & style:
(notice, that the redraw is automatic):
[exBegin]
|v e|
v := StandardSystemView extent:250@250.
e := EllipticalArc boundingBox:(10@10 corner:90@90)
startAngle:0
sweepAngle:270.
v addComponent:((StrokingWrapper on:e)
lineWidth:5;
lineStyle:#dashed;
foregroundColor:(Color red)).
e := EllipticalArc boundingBox:(30@30 corner:70@70)
startAngle:90
sweepAngle:270.
v addComponent:((StrokingWrapper on:e)
lineWidth:5;
lineStyle:#doubleDashed;
foregroundColor:(Color red);
backgroundColor:(Color green)).
v open.
[exEnd]
scrolling:
[exBegin]
|t s v e component|
t := StandardSystemView extent:250@200.
s := HVScrollableView for:View miniScroller:true in:t.
s origin:0.0@0.0 corner:1.0@1.0.
v := s scrolledView.
e := Rectangle origin:10@10 corner:90@90.
