QtRuby发射不起作用

Question

平台:

Darwin * -*s-MacBook-Pro.local 11.4.2 Darwin内核版本11.4.2:8月23日星期四16:25:48 PDT 2012; root:xnu-1699.32.7~1/RELEASE_X86_64 x86_64

Ruby:

ruby 2.0.0p0(2013-02-24修订版39474)[x86_64-darwin11.4.2](由rvm安装)

Qt:

qt:稳定4.8.4(瓶装),HEAD

代码:

require 'Qt'

class Foo < Qt::Object

    signals :my_signal #also tried 'my_signal()'
    slots 'my_slot()'

    def initialize(parent = nil)
        super(parent)

        puts "connecting signal and slot"
        Qt::Object.connect(self, SIGNAL('my_signal()'), self, SLOT('my_slot()'))
        # also tried => connect(self, SIGNAL('my_signal()'), self, SLOT('my_slot()'))

    end

    def emit_my_signal
        puts "sending signal"
        emit my_signal
    end

    def my_slot
        puts "received message from signal"
    end
end


o = Foo.new
o.emit_my_signal

输出:

connecting signal and slot
sending signal

使用Qt.debug_level = Qt :: DebugLevel :: High输出

似乎发射不做任何事情.我也尝试重新安装qt和qtbindings,但问题仍然存在.而且我在同一台机器上尝试使用信号和插槽的PyQt,它就像一个魅力.

有没有人对此有任何想法？这是ruby qtbindings的错误还是我做错了什么？

Answer 1

该代码似乎是正确的。该问题仅在 ruby​​ 和 qtbindings 版本的特定组合中出现，这些版本现已过时。
