我看了不少书，没有涉及到designer设计的ui文件，如何在自己的python中调用窗口或按钮，这个是调用按钮的。

在设计里面选择widget,，再拖出按钮，

# -*- coding: utf-8 -*-

from PyQt4 import QtCore, QtGui
try:
_fromUtf8 = QtCore.QString.fromUtf8
except AttributeError:
def _fromUtf8(s):
return s
try:
_encoding = QtGui.QApplication.UnicodeUTF8
def _translate(context, text, disambig):
return QtGui.QApplication.translate(context, text, disambig, _encoding)
except AttributeError:
def _translate(context, text, disambig):
return QtGui.QApplication.translate(context, text, disambig)
class Ui_Form(object):
def setupUi(self, Form):
Form.setObjectName(_fromUtf8("Form"))
Form.resize(400, 300)
self.pushButton = QtGui.QPushButton(Form)
self.pushButton.setGeometry(QtCore.QRect(160, 210, 75, 23))
self.pushButton.setObjectName(_fromUtf8("pushButton"))
self.retranslateUi(Form)
QtCore.QMetaObject.connectSlotsByName(Form)
def retranslateUi(self, Form):
Form.setWindowTitle(_translate("Form", "Form", None))
self.pushButton.setText(_translate("Form", "PushButton", None))

复制代码

生成代码如上，self.pushButton = QtGui.QPushButton(Form)，这个就是我们后面需要调用的按钮。、

python调用按钮如下。

self.setupUi(self)
self.pushButton.clicked.connect(self.slotChild)
def slotChild(self):
print ('hello')
app = QApplication(sys.argv)
dialog=TestDialog()
dialog.show()
app.exec_()

复制代码

import untitled

self.pushButton.clicked.connect(self.slotChild)
def slotChild(self):
print ('hello')

这行是自己添加的。其他的可以复制使用，运行正常，有图有真相

PyQt4 designer checkBox使用

第一图，先拖入checkBox，和标签

第二图，给checkBox添加触发信号。生成程序里面就是这个“QtCore.QObject.connect(self.checkBox, QtCore.SIGNAL(_fromUtf8("clicked()")), Form.slotcheck)”

生成的代码如下

# -*- coding: utf-8 -*-
# Form implementation generated from reading ui file 'untitled.ui'
#

#
# WARNING! All changes made in this file will be lost!
from PyQt4 import QtCore, QtGui
try:
_fromUtf8 = QtCore.QString.fromUtf8
except AttributeError:
def _fromUtf8(s):
return s
try:
_encoding = QtGui.QApplication.UnicodeUTF8
def _translate(context, text, disambig):
return QtGui.QApplication.translate(context, text, disambig, _encoding)
except AttributeError:
def _translate(context, text, disambig):
return QtGui.QApplication.translate(context, text, disambig)
class Ui_Form(object):
def setupUi(self, Form):
Form.setObjectName(_fromUtf8("Form"))
Form.resize(400, 300)
self.checkBox = QtGui.QCheckBox(Form)
self.checkBox.setGeometry(QtCore.QRect(190, 170, 71, 20))
self.checkBox.setObjectName(_fromUtf8("checkBox"))
self.label = QtGui.QLabel(Form)
self.label.setGeometry(QtCore.QRect(200, 130, 54, 12))
self.label.setObjectName(_fromUtf8("label"))
self.retranslateUi(Form)
QtCore.QObject.connect(self.checkBox, QtCore.SIGNAL(_fromUtf8("clicked()")), Form.slotcheck)
QtCore.QMetaObject.connectSlotsByName(Form)
def retranslateUi(self, Form):
Form.setWindowTitle(_translate("Form", "Form", None))
self.checkBox.setText(_translate("Form", "CheckBox", None))
self.label.setText(_translate("Form", "True", None))

复制代码

def slotcheck(self):
if self.checkBox.isChecked():
self.label.setText("hello")
else:
self.label.setText("world")
app = QApplication(sys.argv)
dialog=TestDialog()
dialog.show()
app.exec_()

复制代码

调用的代码如上，这个就是对应的槽函数，里面就是一些信号响应后的操作。

def slotcheck(self):
if self.checkBox.isChecked():
self.label.setText("hello")
else:
self.label.setText("world")
