Using Example

---

#1：Basic Using（Usable）

---

from simpleeventbus import bus



# Create to event listener(printb should called after printa)

@bus.listen("print")

def printa(ent):

    print(f"hello from printa")

@bus.listen("print",after="printa")

def printb(ent):

    print(f'hello from printb')







# send event

bus.send("print")

#2：Pro Using

---

from simpleeventbus import bus, Event





class StaticEvent(Event, static=True):

    msg: str

class DynaEvent(Event, cancelable=True):

    msg:str



# Create to event listener(printb should called after printa,printc)

@bus.listen(StaticEvent)

def printa(ent):

    print(f"{ent.msg} from printa")

@bus.listen(StaticEvent)

def printb(ent):

    print(f"{ent.msg} from printb")

@bus.listen(StaticEvent, after=["printa","printb"])

def printc(ent):

    print(f'{ent.msg} from printc')

@bus.listen(DynaEvent)

def printd(ent):

    print(f"{ent.msg} from printd")

    ent.cancel()

@bus.listen(DynaEvent,after="printd")

def printe(ent):

    print(f"{ent.msg} from printe")







# send event

bus.send(StaticEvent,"hello")

bus.send(DynaEvent,"hello again")

#3：Own Bus?

---

from simpleeventbus import buses, Bus



bus1 = buses.bus1  # Simplely get a own bus.

bus2 = Bus("bus2")  # Work too.
