AttributeError in tkinter gui programming
I want to display my calculated output in a Gui window in python. I am trying with Tkinter. But I'm having problems displaying the output on Tkinter level widget. I am putting input data as address information in text field of Tkinter window and want latitude, longitude of that inputed address to the text label. Can anyone please help me out of this? I am just quite new to this Tkinter.
code is below:
def initialize(self):
开发者_开发问答 self.grid()
self.entry = Tkinter.Entry(self)
self.entry.grid(column=0,row=0,sticky='EW')
button = Tkinter.Button(self,text=u"Get Geo information !",command=self.OnButtonClick)
button.grid(column=1,row=0)
self.labelVariable = Tkinter.StringVar()
label = Tkinter.Label(self,textvariable=self.labelVariable,
anchor="w",fg="black",bg="white")
label.grid(column=0,row=1,columnspan=2,sticky='EW')
self.grid_columnconfigure(0,weight=1)
self.resizable(True,False)
def OnButtonClick(self):
outf = open(out_file,'w')
outf_failed = open(out_file_failed,'w')
#inf = open(addr_file,'r')
inf = codecs.open(addr_file, 'r', 'iso-8859-1')
for address in inf:
#get latitude and longitude of address
data = geocode(address)
#output results and log to file
if len(data)>1:
self.labelVariable.set( self.entryVariable.get()+" (Latitude )", data['lat'] )
self.labelVariable.set( self.entryVariable.get()+" (Longitude )", data['lng'] )
outf.write(address.strip()+data['lat']+','+data['lng']+'\n')
outf.flush()
else:
self.labelVariable.set( self.entryVariable.get()+" Geocoding of '"+addr_file+"' failed with error code "+data['code'] )
outf_failed.write(address)
outf_failed.flush()
time.sleep(sleep_time)
#clean up
inf.close()
outf.close()
outf_failed.close()
if __name__ == "__main__":
app = simpleapp_tk(None)
app.title('Your Location')
app.mainloop()
And I got error:
File "F:\JavaWorkspace\Test\src\gui_geo_location.py", line 94, in OnButtonClick
self.labelVariable.set( self.entryVariable.get()+" (Latitude )", data['lat'] )
File "C:\Python25\lib\lib-tk\Tkinter.py", line 1721, in __getattr__
return getattr(self.tk, attr)
AttributeError: entryVariable
Here is my __init__
method:
def __init__(self,parent):
Tkinter.Tk.__init__(self,parent)
self.parent = parent
self.initialize()
def initialize(self):
self.grid()
self.entry = Tkinter.Entry(self)
self.entry.grid(column=0,row=0,sticky='EW')
self.entry.bind("<Return>", self.OnPressEnter)
button = Tkinter.Button(self,text=u"Get Geo information !",command=self.OnButtonClick)
button.grid(column=1,row=0)
self.labelVariable = Tkinter.StringVar()
label = Tkinter.Label(self,textvariable=self.labelVariable,
anchor="w",fg="black",bg="white")
label.grid(column=0,row=1,columnspan=2,sticky='EW')
self.grid_columnconfigure(0,weight=1)
self.resizable(True,False)
On line 94 in F:\JavaWorkspace\Test\src\gui_geo_location.py
, you're using self.entryVariable
but that object does not have an entryVariable
attribute.
Based on your __init__
, it seems you haven't defined entryVariable
anywhere. Try adding:
self.entryVariable = Tkinter.StringVar()
to your __init__
method. See this page for more information.
