我为我的插件创建了一个带有3个按钮的启动GUI.这非常有效,如果我单击其中一个按钮,则会启动特定操作.到目前为止这个工作.如果我点击其中一个按钮,新的GUI有两个按钮"ok"和"cancel",并出现一条lineedit.如果我按下取消,GUI将被关闭,如果我按下ok,我希望程序从editline读取文本并将其存储在变量中.到目前为止,这还没有奏效.

这是包含对话框的类:

from PyQt4.QtCore import pyqtSlot
from PyQt4.QtGui import QDialog, QLineEdit

from ui_grz import Ui_Dialog

class grzDialog(QDialog):

    def __init__(self):
        QDialog.__init__(self)
        # Set up the user interface from Designer.
        self.ui = Ui_Dialog()
        self.ui.setupUi(self)

在使用QT Designer和命令pyuic4创建GUI之后,这是一个包含GUI结构的类:

from PyQt4 import QtCore, QtGui

try:
    _fromUtf8 = QtCore.QString.fromUtf8
except AttributeError:
    _fromUtf8 = lambda s: s

class Ui_Dialog(object):
    def setupUi(self, Dialog):
        Dialog.setObjectName(_fromUtf8("Dialog"))
        Dialog.resize(387, 153)
        self.buttonBox = QtGui.QDialogButtonBox(Dialog)
        self.buttonBox.setGeometry(QtCore.QRect(30, 110, 341, 32))
        self.buttonBox.setOrientation(QtCore.Qt.Horizontal)
        self.buttonBox.setStandardButtons(QtGui.QDialogButtonBox.Cancel|QtGui.QDialogButtonBox.Ok)
        self.buttonBox.setObjectName(_fromUtf8("buttonBox"))
        self.label = QtGui.QLabel(Dialog)
        self.label.setGeometry(QtCore.QRect(10, 10, 361, 51))
        self.label.setObjectName(_fromUtf8("label"))
        self.lineEdit = QtGui.QLineEdit(Dialog)
        self.lineEdit.setGeometry(QtCore.QRect(10, …
