I am a total noob when i comes to Python. But i wanted to give it a try as i need a GUI. I understand bash shell scripting a lot better so i want to use that in my "program" even though i know it would be better to do it all in python.

So where am i going wrong?

(attaching the complete file below)

Code:

        self.retranslateUi(dialog)
        QtCore.QObject.connect(self.pushButton, QtCore.SIGNAL(_fromUtf8("clicked()")), dialog.open)
        QtCore.QObject.connect(self.pushButton_2, QtCore.SIGNAL(_fromUtf8("clicked()")), dialog.open)
        QtCore.QObject.connect(self.pushButton_3, QtCore.SIGNAL(_fromUtf8("clicked()")), dialog.open)
        QtCore.QObject.connect(self.pushButton_4, QtCore.SIGNAL(_fromUtf8("clicked()")), dialog.close)
        QtCore.QMetaObject.connectSlotsByName(dialog)
        dialog.setTabOrder(self.pushButton, self.pushButton_3)
        dialog.setTabOrder(self.pushButton_3, self.pushButton_2)
        dialog.setTabOrder(self.pushButton_2, self.pushButton_4)

	def self(dialog):
		f = ("/home/daniel/Hämtningar/n900/awoken-extras/test.sh");
		import subprocess
		subprocess.call("/bin/sh " + f, shell=True);
		print "open(self) started"

Thanks, but i already figurred that one out.

Right now i am trying with this two:

Code:

	def open(dialog):
		f = ("/home/daniel/Hämtningar/n900/awoken-extras/test.sh");
		import subprocess
		subprocess.call("/bin/sh " + f, shell=True);

	def dialog(pushButton_2):
		f = ("/home/daniel/Hämtningar/n900/awoken-extras/test.sh");
		from subprocess import Popen
		Popen('/bin/sh ' + f);

I somehow can't "connect" the button click event with the subprocess. When i run it nothing happens. So i think i am doing the "def" string wrong.

When i do this i get an error.

Code:

        self.retranslateUi(dialog)
        QtCore.QObject.connect(self.pushButton, QtCore.SIGNAL(_fromUtf8("clicked()")), self.open)
	def open(self):
		f = ("/home/daniel/Hämtningar/n900/awoken-extras/test.sh");
		import subprocess
		subprocess.call(["/bin/sh " + f]);

The error:

Code:

Traceback (most recent call last):
  File "awoken.py", line 82, in <module>
    ui.setupUi(dialog)
  File "awoken.py", line 43, in setupUi
    QtCore.QObject.connect(self.pushButton, QtCore.SIGNAL(_fromUtf8("clicked()")), self.open)

Solved! I got some help from my friend Wellef and sorted it out. I will attach the file in case someone els finds it useful.

This is how it should look:

Code:

        self.retranslateUi(MainWindow)
        QtCore.QObject.connect(self.pushButton, QtCore.SIGNAL(_fromUtf8("clicked()")), self.change)
        QtCore.QObject.connect(self.pushButton_3, QtCore.SIGNAL(_fromUtf8("clicked()")), self.backup)
        QtCore.QObject.connect(self.pushButton_2, QtCore.SIGNAL(_fromUtf8("clicked()")), self.reset)
        QtCore.QObject.connect(self.pushButton_4, QtCore.SIGNAL(_fromUtf8("clicked()")), MainWindow.close)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def change(self):
	os.system("/home/daniel/Hämtningar/n900/awoken-extras/test.sh");

    def backup(self):
	os.system("/home/daniel/Hämtningar/n900/awoken-extras/test.sh");

    def reset(self):
	os.system("/home/daniel/Hämtningar/n900/awoken-extras/test.sh");
