Eventhanders calling other other eventhandlers with args

[Alek99]

Event handlers should be able to call other event handlers with arguments. I think the best way would be todo this with a lambda similar to how its done in our ui elements.

class State(pc.State):
    """The app state."""
    self.option: str = "DFS"

    def bfs(self, arg1, arg2):
       ...

    def dfs(self, arg1, arg2):
       ...

    def run(self):
            """Run the selected algorithm.""
            if self.option == "DFS":
                return lambda _: self.dfs(arg1, arg2)
            elif self.option == "BFS":
                return   lambda _: self.bfs(arg1, arg2)

Open to other suggestions.

How hard is it to support calling the method directly?

When we do self.bfs we are referring to the function, but if we do State.bfs it should refer to the event handler itself. Maybe an alternative is that when returning, you should always use the class property, for example:

def run(self):
    """Run the selected algorithm."""
    if self.option == "DFS":
        return State.dfs(arg1, arg2)
    elif self.option == "BFS":
        return State.bfs(arg1, arg2)
