The documentation for the GUI's button control seems to be wrong.

https://www.autohotkey.com/docs/commands/GuiControls.htm#Button

Code: Select all

#Requires AutoHotkey v2.0-beta

#n::
{
	MyGui := Gui()
	MyBtn := MyGui.Add("Button", "Default w80", "OK")
	MyBtn.OnEvent("Click", MyBtn_Click())  ; 当点击时调用 MyBtn_Click.
}

MyBtn_Click() {
	Msgbox "OK"
}

I wrote these codes and run.
But when I press Win+n, the MyBtn_Click function seems to be executed immediately.
But according to the introduction in the documentation, this function should be called after I click the OK button?

"the MyBtn_Click function seems to be executed immediately" because that is precisely what u instructed ahk to do: MyBtn.OnEvent("Click", MyBtn_Click()) - call the function
also, ure linking to v1 docs
also, u dont understand the v2 docs(u need to pass a function reference, not call the function. in other words: MyBtn.OnEvent("Click", MyBtn_Click))
also, u still dont understand the v2 docs(ur click handler is declared as a 0-ary function and will blow up as soon as the Click event would attempt to inject GuiCtrlObj and Info when calling the handler function)
