import sys
import os
from search import Ui_MainWindow as UIMW
from PyQt4 import QtCore, QtGui
import urllib2 as ulib
import sqlite3
from pysqlite2 import dbapi2 as sqlite3

def globalF():
	connection = sqlite3.connect('Photos.db')
        memoryConnection = sqlite3.connect(':memory:')
        cursor = connection.cursor()
	cursor.execute('SELECT * FROM photos where Tag = "Tag"')
        print cursor.fetchall()

class MainWindow (QtGui.QMainWindow, UIMW):
	
	def __init__(self):
		QtGui.QMainWindow.__init__(self)
		self.setupUi(self)
		self.__setupConnection()
		
	def __setupConnection(self):
		self.connect(self.pushButton, QtCore.SIGNAL("clicked()"), globalF)
		
	def _pushButtonClicked(self):
		search=str(self.lineEdit.text()).strip()
		
		if search:
			try:
				self.listWidget.append(ulib.searchresult(search).read())
			except:
				pass
		else:
			pass
		
		
if __name__=="__main__":
	app=QtGui.QApplication(sys.argv)
	w=MainWindow()
	w.show()
	sys.exit(app.exec_())
