Body
<p>came across your code to select a date. Recently had to write a simple calendar for similar purposes. I can offer you that option as an alternative. I think this option is more convenient to choose the date. </p> <pre><code>import calendar, datetime, Tkinter class calendarTk(Tkinter.Frame): # class calendarTk """ Calendar, the current date is exposed today, or transferred to date""" def __init__(self,master=None,date=None,dateformat="%d/%m/%Y",command=lambda i:None): Tkinter.Frame.__init__(self, master) self.dt=datetime.datetime.now() if date is None else datetime.datetime.strptime(date, dateformat) self.showmonth() self.command=command self.dateformat=dateformat def showmonth(self): # Show the calendar for a month sc = calendar.month(self.dt.year, self.dt.month).split('\n') for t,c in [('<<',0),('<',1),('>',5),('>>',6)]: # The buttons to the left to the right year and month Tkinter.Button(self,text=t,relief='flat',command=lambda i=t:self.callback(i)).grid(row=0,column=c) Tkinter.Label(self,text=sc[0]).grid(row=0,column=2,columnspan=3) # year and month for line,lineT in [(i,sc[i+1]) for i in range(1,len(sc)-1)]: # The calendar for col,colT in [(i,lineT[i*3:(i+1)*3-1]) for i in range(7)]: # For each element obj=Tkinter.Button if colT.strip().isdigit() else Tkinter.Label # If this number is a button, or Label args={'command':lambda i=colT:self.callback(i)} if obj==Tkinter.Button else {} # If this button, then fasten it to the command bg='green' if colT.strip()==str(self.dt.day) else 'SystemButtonFace' # If the date coincides with the day of date - make him a green background fg='red' if col>=5 else 'SystemButtonText' # For the past two days, the color red obj(self,text="%s"% colT,relief='flat',bg=bg,fg=fg,**args).grid(row=line, column=col, ipadx=2, sticky='nwse') # Draw Button or Label def callback(self,but): # Event on the button if but.strip().isdigit(): self.dt=self.dt.replace(day=int(but)) # If you clicked on a date - the date change elif but in ['<','>','<<','>>']: day=self.dt.day if but in['<','>']: self.dt=self.dt+datetime.timedelta(days=30 if but=='>' else -30) # Move a month in advance / rewind if but in['<<','>>']: self.dt=self.dt+datetime.timedelta(days=365 if but=='>>' else -365) # Year forward / backward try: self.dt=self.dt.replace(day=day) # We are trying to put the date on which stood except: pass # It is not always possible self.showmonth() # Then always show calendar again if but.strip().isdigit(): self.command(self.dt.strftime(self.dateformat)) # If it was a date, then call the command if __name__ == '__main__': def com(f): print f root = Tkinter.Tk() root.title("Monthly Calendar") c=calendarTk(root,date="21/11/2006",dateformat="%d/%m/%Y",command=com) c.pack() root.mainloop() </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
