如何通过单击PyQt中的按钮将参数传递给函数? [英] How to pass arguments to functions by the click of button in PyQt?

问题描述

我想在单击按钮时将参数传递给函数.我应该在此行button.connect(button, QtCore.SIGNAL('clicked()'), calluser(name))中添加什么，以便它将值传递给函数:

I want to pass the arguments to a function when I click the button. What should I add to this line button.connect(button, QtCore.SIGNAL('clicked()'), calluser(name)) so it will pass the value to the function:

def calluser(name):
    print name

def Qbutton():
    button = QtGui.QPushButton("button",widget)
    name = "user"
    button.setGeometry(100,100, 60, 35)
    button.connect(button, QtCore.SIGNAL('clicked()'), calluser(name))

另一件事，将使用for循环生成按钮；因此name值会有所不同.因此，我想在按钮上附加每个名称.通过使用for循环并在单击时调用基函数自变量，我在Pytk中做了同样的事情.

One more thing, buttons will be generated using for loop; so name value will vary. So I want to attach each name with the button. I have done same thing in Pytk by using for loop and calling the argument base function when clicked.

推荐答案

您只需编写

name = "user"
button.clicked.connect(lambda: calluser(name))
