I cant understand what im doing wrong. Heres the code
gui.py:
from PyQt4 import QtCore, QtGui
import sys
from subprocess import Popen
class Ui_MainWindow(object):
fileinit=False
paused=True
quit=False
filename=""
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(394, 414)
self.centralwidget = QtGui.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.scrollArea = QtGui.QScrollArea(self.centralwidget)
self.scrollArea.setGeometry(QtCore.QRect(19, 9, 361, 281))
self.scrollArea.setWidgetResizable(True)
self.scrollArea.setObjectName("scrollArea")
self.scrollAreaWidgetContents = QtGui.QWidget(self.scrollArea)
self.scrollAreaWidgetContents.setGeometry(QtCore.QRect(0, 0,
357, 277))
self.scrollAreaWidgetContents.setObjectName("scrollAreaWidgetContents")
self.textEdit = QtGui.QTextEdit(self.scrollAreaWidgetContents)
self.textEdit.setGeometry(QtCore.QRect(-7, -6, 371, 291))
self.textEdit.setObjectName("textEdit")
self.scrollArea.setWidget(self.scrollAreaWidgetContents)
self.pushButton = QtGui.QPushButton(self.centralwidget)
self.pushButton.setGeometry(QtCore.QRect(30, 310, 80, 25))
self.pushButton.setObjectName("pushButton")
self.pushButton_2 = QtGui.QPushButton(self.centralwidget)
self.pushButton_2.setGeometry(QtCore.QRect(139, 310, 91, 25))
self.pushButton_2.setObjectName("pushButton_2")
self.pushButton_3 = QtGui.QPushButton(self.centralwidget)
self.pushButton_3.setGeometry(QtCore.QRect(280, 310, 80, 25))
self.pushButton_3.setObjectName("pushButton_3")
MainWindow.setCentralWidget(self.centralwidget)
self.menubar = QtGui.QMenuBar(MainWindow)
self.menubar.setGeometry(QtCore.QRect(0, 0, 394, 23))
self.menubar.setObjectName("menubar")
MainWindow.setMenuBar(self.menubar)
self.statusbar = QtGui.QStatusBar(MainWindow)
self.statusbar.setObjectName("statusbar")
MainWindow.setStatusBar(self.statusbar)
self.retranslateUi(MainWindow)
QtCore.QObject.connect(self.pushButton,
QtCore.SIGNAL("clicked()"), self.Open)
QtCore.QObject.connect(self.pushButton_2,
QtCore.SIGNAL("clicked()"), self.Pause)
QtCore.QObject.connect(self.pushButton_3,
QtCore.SIGNAL("clicked()"), self.Quit)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
def retranslateUi(self, MainWindow):
MainWindow.setWindowTitle(QtGui.QApplication.translate("MainWindow",
"MainWindow", None, QtGui.QApplication.UnicodeUTF8))
self.pushButton.setText(QtGui.QApplication.translate("MainWindow",
"Open", None, QtGui.QApplication.UnicodeUTF8))
self.pushButton_2.setText(QtGui.QApplication.translate("MainWindow",
"Pause/Resume", None, QtGui.QApplication.UnicodeUTF8))
self.pushButton_3.setText(QtGui.QApplication.translate("MainWindow",
"Quit", None, QtGui.QApplication.UnicodeUTF8))
def Pause(self):
print "Pause"
self.paused=not(self.paused)
def Quit(self):
self.quit=True
print "setting quit"
def Open(self):
print "Open"
self.filename=QtGui.QFileDialog.getOpenFileName()
self.filename=str(self.filename)
try:
f=open("book.txt","r")
except IOError:
f=open("log.txt",'w')
f.write('0')
f.close()
old=f.read(20)
f.close()
f=open(self.filename,'r')
new=f.read(20)
f.close()
if(old!=new):
f=open("log.txt",'w')
f.write('0')
f.close()
f=open("book.txt",'w')
f.write(new)
f.close()
self.fileinit=True
print "setting fileinit"
and heres the main.py
from PyQt4 import QtCore, QtGui
import sip,gui
import sys
from subprocess import Popen
from threading import Thread
class AppThread(Thread):
appinit=False
def run(self):
self.app = QtGui.QApplication(sys.argv)
MainWindow = QtGui.QMainWindow()
self.ui = gui.Ui_MainWindow()
self.ui.setupUi(MainWindow)
MainWindow.show()
self.appinit=True
sys.exit(self.app.exec_())
class Speak(Thread):
def run(self):
print "starting speaker"
try:
log=open("log.txt",'r')
print log
self.index=log.read()
log.close()
self.index=int(self.index)
except IOError:
print "setting new"
index=0
#by now, index has been defined for both a new and an old book
self.book=open(a.ui.filename,'r')
self.book.seek(self.index)
while(a.ui.quit==False):
if (a.ui.paused==False):
sen=self.readsen()
******** a.ui.textEdit.setText(sen)
command="soundwrapper espeak "+' " '+sen+' " '
k=Popen(command,shell=True)
k.wait()
print "quitted loop"
index=self.book.tell()
log=open("log.txt","w")
log.write(str(index))
log.close()
print "calling exit"
a.app.exit()
sys.exit()
def readsen(self):
line=""
sen=""
while(line.find(".")== -1):
sen=sen+line
line=self.book.readline()
sen=sen+line[0:line.find(".")+1]
self.book.seek(self.book.tell()-len(line)+line.find(".")+1)
return sen
a=AppThread()
a.start()
while 1:
if a.appinit== True:
if a.ui.fileinit==True:
s=Speak()
s.start()
break
Look at the line with many stars at the left. Is that an incorrect way
of calling the setText method of the textEdit in the other thread?
Pls Help,
Regards
Soumen
