I have a problem with python 2.7.
Question: When I use the zoom function, I can not use the "keyboard" to print my real data. Here, I add the keyboard event in my code.
How do I exist in both functions? How should I debug the code?

If you don't want to remove the default behavior of a method then you must invoke the parent method:

super(MyMplCanvas, self).mouseReleaseEvent(event)
if event.button() == Qt.LeftButton:

Here in my sample program,I want to display the lot of names in list widget.In that, I want to search a particular item in list widget using search button,and I want to print that item name in list widget.
Given below is my code:
import sys
from PyQt4 import QtGui, QtCore
class Example(QtGui.QWidget):
def __init__(self):
super(Example, self).__init__()
self.initUI()
def initUI(self):
auto_search_vbox = QtGui.QVBoxLayout(self)
hbox=QtGui.QHBoxLayout()
le_search = QtGui.QLineEdit()
se_btn = QtGui.QPushButton("Search")
se_btn.clicked.connect(self.find_item)
hbox.addWidget(le_search)
hbox.addWidget(se_btn)
auto_search_vbox.addLayout(hbox)
self.listwidget = QtGui.QListWidget()
self.total_list =["machine","printer","xerox bundles"]
self.listwidget.addItems(self.total_list)
auto_search_vbox.addWidget(self.listwidget)
self.show()
def find_item(self):
out = self.listwidget.findItems("mac", QtCore.Qt.MatchExactly)
print out
def main():
app = QtGui.QApplication(sys.argv)
ex = Example()
sys.exit(app.exec_())
if __name__ == '__main__':
main()
Sorry, I have PyQt5. Try it:
flags Qt::MatchFlags
This enum describes the type of matches that can be used when searching for items in a model.

the above code i have done the following. I have imported the UI designed using QI designer and called matplotlib backend for putting matplotlib greaph in my app

In the above code, I have declared a class Main which initialises the UI code imported from Qt designer and there are tw functions one is to initialise the map canvas and other to import data from another file and plot it on the click of the RawData button.
but if you try to run the code, the graph doesnot display any content

There were some minor mistakes which I rectified.
i just want to ask, what's wrong with my codes, or am i missing something. because when i call the function PausePlay() in the PlayAndPause() I always get an error saying:
