I wrote a gui with qt and converted it into python.it came below.
know I want to use the information witch user entered.for example the text boxes text or want decide around the buttons clicked or any thing else.at all how can i manage my qt forms data in my program?

from PyQt4 import QtCore, QtGui

class Ui_Dialog(object):
    def setupUi(self, Dialog):
        Dialog.setObjectName("Dialog")
        Dialog.resize(324, 202)
        self.pushButton = QtGui.QPushButton(Dialog)
        self.pushButton.setGeometry(QtCore.QRect(190, 160, 101, 23))
        self.pushButton.setObjectName("pushButton")
        self.pushButton_2 = QtGui.QPushButton(Dialog)
        self.pushButton_2.setGeometry(QtCore.QRect(10, 160, 101, 23))
        self.pushButton_2.setObjectName("pushButton_2")
        self.textEdit = QtGui.QTextEdit(Dialog)
        self.textEdit.setGeometry(QtCore.QRect(210, 10, 104, 31))
        self.textEdit.setLayoutDirection(QtCore.Qt.RightToLeft)
        self.textEdit.setTabChangesFocus(True)
        self.textEdit.setObjectName("textEdit")
        self.textEdit_2 = QtGui.QTextEdit(Dialog)
        self.textEdit_2.setGeometry(QtCore.QRect(210, 60, 104, 31))
        self.textEdit_2.setLayoutDirection(QtCore.Qt.RightToLeft)
        self.textEdit_2.setTabChangesFocus(True)
        self.textEdit_2.setObjectName("textEdit_2")
        self.textEdit_3 = QtGui.QTextEdit(Dialog)
        self.textEdit_3.setGeometry(QtCore.QRect(10, 10, 104, 31))
        self.textEdit_3.setLayoutDirection(QtCore.Qt.RightToLeft)
        self.textEdit_3.setTabChangesFocus(True)
        self.textEdit_3.setObjectName("textEdit_3")
        self.textEdit_4 = QtGui.QTextEdit(Dialog)
        self.textEdit_4.setGeometry(QtCore.QRect(10, 60, 104, 31))
        self.textEdit_4.setLayoutDirection(QtCore.Qt.RightToLeft)
        self.textEdit_4.setTabChangesFocus(True)
        self.textEdit_4.setObjectName("textEdit_4")
        self.textEdit_5 = QtGui.QTextEdit(Dialog)
        self.textEdit_5.setGeometry(QtCore.QRect(110, 110, 104, 31))

        self.textEdit_5.setTabChangesFocus(True)
        self.textEdit_5.setObjectName("textEdit_5")

        self.retranslateUi(Dialog)

if __name__ == "__main__":
    import sys
    app = QtGui.QApplication(sys.argv)
    Dialog = QtGui.QDialog()
    ui = Ui_Dialog()
    ui.setupUi(Dialog)
    Dialog.show()
    sys.exit(app.exec_())

I used qt designer for this code.

fetching data from qt

The short answer is to look at QLineEdit here http://www.devshed.com/c/a/Python/PyQT-Input-Widgets/ More tutorials are on the wiki http://www.diotavelli.net/PyQtWiki/Tutorials

from PyQt4 import QtCore, QtGui

class Ui_frmMain(object):
    def setupUi(self, frmMain):
        frmMain.setObjectName("frmMain")
        frmMain.resize(254, 170)

if __name__ == "__main__":
    import sys
    app = QtGui.QApplication(sys.argv)
    frmMain = QtGui.QDialog()
    ui = Ui_frmMain()
    ui.setupUi(frmMain)
    frmMain.show()
    sys.exit(app.exec_())

if my code be such. now

QtCore.QObject.connect(self.btnSave, QtCore.SIGNAL("clicked()"), self.setValue)

clicked is my event and my signal.and it will be call the setValue() function witch is my slot.

def setValue(self):
    name = txtName.؟؟؟؟؟

now I have problem for accessing the txtNames value.
how do you solve this.

and another question.The way that I did is a usual way.
Its my first time that am runing such program.before I dont worked with guies.when a programer wants do such program, how does he play?

This is an example I had using QLineEdit and QTextEdit. There are other ways to retrieve text based on starting and ending positions but I don't use it.

import sys
from PyQt4 import QtGui, QtCore

class GridLayout2(QtGui.QWidget):
    def __init__(self, parent=None):
        QtGui.QWidget.__init__(self, parent)

        self.setWindowTitle('grid layout')

        title = QtGui.QLabel('Title')
        author = QtGui.QLabel('Author')

        self.title_edit = QtGui.QLineEdit()
        self.author_edit = QtGui.QTextEdit()

        grid = QtGui.QGridLayout()
        grid.setSpacing(10)

        grid.addWidget(title, 1, 0)
        grid.addWidget(self.title_edit, 1, 1)

        grid.addWidget(author, 2, 0)
        grid.addWidget(self.author_edit, 2, 1)

        c_button = QtGui.QPushButton("Continue")
        grid.addWidget(c_button, 3, 0)
        self.connect(c_button, QtCore.SIGNAL("clicked()"), \
                     self.button_click)

        quit_button = QtGui.QPushButton("Exit")
        grid.addWidget(quit_button, 3, 1)
        self.connect(quit_button, QtCore.SIGNAL("clicked()"), \
                     self.exit_widget)

        self.setLayout(grid)
        self.resize(250, 150)


    def button_click(self):
        print "button click called"
        print "self.title_edit", self.title_edit.text()
        print "\nself.author_edit"
        print self.author_edit.document().toPlainText()


    def exit_widget(self):
        self.button_click()
        self.close()

app = QtGui.QApplication(sys.argv)
qb = GridLayout2()
qb.show()
sys.exit(app.exec_())

Thanks.
