我喜欢在 QSlider 和 QSpinBox 之间共享数据。 如果我编辑一个, 另一个应该得到相同的值, 而不必使用 模型查看代表结构手动完成 。
任何想法如何使用这个结构 与整数模型?
谢谢 谢谢
我不知道我是否理解你的问题,但在 Qt 中这样做的标准方法是使用内置信号和空格 value-value(int) 和 setValue(int) :
connect(slider, SIGNAL(valueChanged(int)), spinbox, SLOT(setValue(int)));
connect(spinbox, SIGNAL(valueChanged(int)), slider, SLOT(setValue(int)));
请注意,这不会产生无限的循环, 在两行代码下,它相当自动。
