我在Windows 64位上有python 2.7 还要将pyQt4添加到python \ 开始添加这样的代码:

from PyQt4.QtCore import *
from PyQt4.QtGui import *
import sys

from PyQt4.QtCore import *
from PyQt4.QtGui import *
import sys


class HelloWorld(QDialog):
    def __init__(self):
        QDialog.__init__(self)

        layout = QVBoxLayout()

        label = QLabel("Hello world")
        line_edit = QLineEdit()
        button = QPushButton("close")

        layout.addWidget(label)
        layout.addWidget(line_edit)
        layout.addWidget(button)

        self.setLayout(layout)

我从来没有看到我的代码既没有实现空白标题的空白窗口!!

from PyQt4 import QtGui
import sys

class HelloWorld(QtGui.QDialog):
    def __init__(self):
        QtGui.QDialog.__init__(self)

        layout = QtGui.QVBoxLayout()

        label = QtGui.QLabel("Hello world")
        line_edit = QtGui.QLineEdit()
        button = QtGui.QPushButton("close")

        layout.addWidget(label)
        layout.addWidget(line_edit)
        layout.addWidget(button)

        self.setLayout(layout)
到目前为止,这么好。 要按F5添加:

来测试代码
def main():

    app = QtGui.QApplication(sys.argv)
    hw = HelloWorld()
    hw.show()
    sys.exit(app.exec_())

   if __name__ == '__main__':
        main()
