Got an initial event setup that seems to have potential. It looks to be
scalable from a single widget to global or in between without too much work.
type
IncrementBar = object
target: float
proc animatedProgress*(delta: float32 = 0.1) {.statefulFidget.} =
properties:
value: float
self.value = self.value + delta
## handle events
var v {.inject.}: Variant
if not current.hookEvents.isNil and
current.hookEvents.pop(current.code, v):
variantMatch case v as evt
of IncrementBar:
echo "pbar event: ", evt.repr()
self.value = self.value + evt.target
refresh()
else:
echo "dont know what v is"
...
Run
Then:
proc exampleApp*(myName {.property: name.}: string) {.appFidget.} =
## defines a stateful app widget
properties:
count1: int
count2: int
value: UnitRange
if current.hookEvents.isNil:
current.hookEvents = newTable[string, Variant]()
let currEvents = current.hookEvents
...
# Trigger an animation on animatedProgress below
Widget button:
text: fmt"Animate {self.count2:4d}"
onClick:
self.count2.inc()
currEvents["pbc1"] = newVariant(IncrementBar(target: 0.02))
Widget animatedProgress:
delta: delta
setup:
box 0'em, 0'em, 14'em, 2.Em
current.code = "pbc1"
current.hookEvents = currEvents
Widget button:
text: fmt"Animate2 {self.count2:4d}"
onClick:
self.count2.inc()
currEvents["pbc1"] = newVariant(IncrementBar(target: 0.02))
Run
