[待解决问题]
如下，我要实现打开工具时不显示控件plainTextEdit ，然后点击pushubutton_1时控件显示出来，再点击pushbutton_2，控件就隐藏。我之前用了self.plainTextEdit.setVisible(False)去实现，但是有个问题就是，我点击pushubutton_1控件显示出来后，再点击pushbutton_2，控件还是显示状态。此处应该怎样实现呢? 谢谢了！

你试试
可以的。谢谢！另外我想请教下，如果我这这里假如说有50个button，除了button_1点击显示这个输入框控件，其它点击全部隐藏，怎样把剩下的49个button绑定到一个函数呢?要写49个connect的话虽然可以，但是不是太麻烦了点？
@liyangzbx: for循环绑定同一个函数啊，哈哈哈
@临冬城城主: 这个button不是有个下标吗，button_2,button_3....这要怎样循环？
