I'm using raspberry pi because i need a GUI to display my LED blinker counter project. I'm having an error in
IntVar()
It says that it has attribute error __trunc__ Here is my code:
import sys
import RPi.GPIO as GPIO
import time
import math
from Tkinter import *
GPIO.setmode(GPIO.BOARD)
GPIO.setup(16, GPIO.OUT)
root = Tk()
root.geometry("200x200")
root.title("Simple Counter")
counter = IntVar()
def onClick1(event=None):
counter.set(counter.get()+1)
def onClick2(event=None):
counter.set(counter.get()-1)
def count():
for x in range(0, counter):
GPIO.output(16, True)
time.sleep(0.5)
GPIO.output(16, False)
entry = Entry(root, textvariable=counter).pack()
button = Button(root, text="Press to Add", command=onClick1).pack()
button2 = Button(root, text="Press to Subtract", command=onClick2).pack()
button3 = Button(root, text="Press to Continue", command=count).pack()
root.mainloop()
The problem is in the line:
for x in range(0, counter):
it should be
for x in range(0, counter.get()):
like it is in your onClick functions.

I'm new to python. I'm trying to set up a GUI with a main window and a modal window to receive the database credentials. The main window has to be in the background when the modal window appears and the user should not interact with it. Actually the application should terminate in case the user fails to provide a valid username and password. I'm presenting part of the code here. What I get is the main window (the modal window does not appear at all) and I can't do anything but shut the program down - not directly; only through visual studio.
'''
import tkinter as tk
class login:
def checkDbCredentials(self, user, password):
if (len(user)<4 or len(password)<4):
return 0
return 1
def ok(self):
us = self.user.get()
pw = self.password.get()
if self.checkDbCredentials(us, pw)==0:
tk.messagebox.showinfo("Error", "Username and Password do not match")
sys.exit(0)
self.dic['user']=us
self.dic['pass']=pw
self.win2.destroy()
def cancel(self, event=None):
self.parent.focus_set()
self.destroy()
def widgets(self):
x = self.win2.winfo_screenwidth()
y = self.win2.winfo_screenheight()
xx = int((x-270)/2)
yy = int((y-85)/2)
geo = "270x85+" + str(xx) + "+" + str(yy)
self.win2.geometry(newGeometry=geo)
self.tempLab= tk.Label(self.win2, text="Username:", pady=5)
self.tempLab1 = tk.Label(self.win2, text="Password:")
self.iuser = tk.Entry(self.win2, textvariable = self.user, width=30)
self.ipass = tk.Entry(self.win2, textvariable = self.password, width=30, show="*")
self.tempLab.grid(column=0, row=0)
self.tempLab1.grid(column=0, row=1)
self.iuser.grid(column=1, row=0)
self.ipass.grid(column=1, row=1)
self.bt = tk.Button(self.win2, text="Submit", command=lambda: self.ok())
self.bt.grid(column=0, row=2, columnspan=2, pady=5)
self.win2.bind("<Return>", self.ok)
self.win2.bind("<Escape>", self.cancel)
def __init__(self, dic, parent):
self.win2 = tk.Toplevel(parent)
self.parent=parent
self.dic = dic
self.user = tk.StringVar()
self.password = tk.StringVar()
self.win2.overrideredirect(1)
self.widgets()
self.win2.transient(parent)
self.win2.grab_set()
self.win2.protocol("WM_DELETE_WINDOW", self.cancel)
self.parent.wait_window(self.win2)
And the main class code is the following:
import tkinter as tk
from tkinter import ttk, X, Y, BOTH
from tkinter import messagebox
import sys
import login
class mainWindow:
def connect(bt, fr):
notImplementedYet()
def notImplementedYet():
msg = tk.messagebox
msg.showinfo("Warning", "Not Implemented yet!")
btX = 20
btY = 5
btSunken = '#aec2c2' # sunken button color
btRaised = '#85adad' # normal button color
rw = 0 # starting row for buttons
cl = 0 # starting column
dbCredentials = {"user":"", "pass":""}
win = tk.Tk()
win.title("Title")
win.geometry(newGeometry="1366x700+00+00")
win.iconbitmap(bitmap="bitmap.ico")
fr1 = tk.Frame(win, width=1366, height=50, background='beige')
fr1.grid(column=cl, row=rw, rowspan=5)
fr2 = tk.Frame(win)
fr2.grid(column=0, row=1)
lb2 = tk.Label(fr2, text="frame 2", background=btRaised)
btConnect = tk.Button(fr1, text="Connect", background = btRaised ,command=lambda: connect(btConnect, fr1), width=btX, height=btY)
btConnect.grid(column=0, row=0)
log = login.login(dbCredentials, win)
win.wait_window(log.win2)
print(dbCredentials)
win.mainloop()
win = mainWindow()
The question is why is the modal window not appearing? I've tried placing the 'wait_window' in the other class as well but it's still not working.
How can i control each button individually in tkinter?
Here is my code:
from tkinter import *
class Minesweeper:
def __init__(self,action):
L=[]
for i in range(15):
for j in range(15):
self.action = Button(win, text = " h ",command = self.clickMe)
self.action.grid(column = i, row = j)
def clickMe(self):
self.action.configure(foreground = "red")
def main():
global win
win = Tk()
win.title('Minesweeper')
game = Minesweeper(win)
win.mainloop()
main()
Better way is a binding some event to button:
from tkinter import *
class Minesweeper:
def __init__(self, action):
L=[]
for i in range(15):
for j in range(15):
self.action = Button(win, text="h")
# bind to button function 'clickMe' that runs while <Button-1> clicked on it
self.action.bind("<Button-1>", self.clickMe)
self.action.grid(column=i, row=j)
def clickMe(self, event):
"""changes the 'fg' color of the events widget"""
event.widget.configure(foreground="red")
def main():
global win
win = Tk()
win.title('Minesweeper')
game = Minesweeper(win)
win.mainloop()
main()
The code picture needs to fit the screen size perfectly. I saw a bunch of tutorials but nothing seems to work.I tried adding a canvas but it covers half the screen.All my buttons go under the image itself not over it. It's getting on my nerves .
here's my code :
import tkinter as tk
import PIL
from PIL import Image, ImageTk
from tkinter import *
from tkinter import filedialog
from tkinter import messagebox
root = Tk()
w = Label(root, text="Send and receive files easily")
w.config(font=('times', 32))
w.pack()
def create_window():
window = tk.Toplevel(root)
window.geometry("400x400")
tower= PhotoImage(file="D:/icons/tower.png")
towlab=Button(root,image=tower, command=create_window)
towlab.pack()
class Window(Frame):
def __init__(self, master=None):
Frame.__init__(self, master)
self.master = master
self.init_window()
def init_window(self):
self.master.title("Bifrost v1.0")
self.pack(fill=BOTH, expand=1)
self.img1 = PhotoImage(file="D:/icons/download.png")
self.img2 = PhotoImage(file="D:/icons/upload.png")
sendButton = Button(self, image=self.img2)
sendButton.place(x=305, y=15)
receiveButton = Button(self, image=self.img1)
receiveButton.place(x=355, y=15)
menu = Menu(self.master)
self.master.config(menu=menu)
file = Menu(menu)
file.add_command(label='Exit', command=self.client_exit)
menu.add_cascade(label='File', menu=file)
edit = Menu(menu)
edit.add_command(label='abcd')
menu.add_cascade(label='Edit', menu=edit)
help = Menu(menu)
help.add_command(label='About Us', command=self.about)
menu.add_cascade(label='Help', menu=help)
def callback():
path = filedialog.askopenfilename()
e.delete(0, END) # Remove current text in entry
e.insert(0, path) # Insert the 'path'
# print path
w = Label(root, text="File Path:")
e = Entry(root, text="")
b = Button(root, text="Browse", fg="#a1dbcd", bg="black", command=callback)
w.pack(side=TOP)
e.pack(side=TOP)
b.pack(side=TOP)
def client_exit(self):
exit()
def about(self):
top = Toplevel()
msg = Message(top, text="This is a project developed by Aditi,Sagar and
Suyash as the final year project.",
font=('', '15'))
msg.pack()
top.geometry('200x200')
button = Button(top, text="Okay", command=top.destroy)
button.pack()
top.mainloop()
root.resizable(0,0)
#size of the window
root.geometry("700x400")
app = Window(root)
root.mainloop()
Overlaying elements is tricky. I think this might be approximately what you're looking for. At least it's a start...

master.update()
win_width = int(master.winfo_width())
win_height = int(master.winfo_height())
# Resize the image to the constraints of the root window.
tower = tower.resize((win_width, win_height))
tower_tk = ImageTk.PhotoImage(tower)
# Create a label to hold the background image.
canvas = Canvas(master, width=win_width, height=win_height)
canvas.place(x=0, y=0, anchor='nw')
canvas.create_image(0, 0, image=tower_tk, anchor='nw')
canvas.image = tower_tk
frame = Frame(master)
frame.place(x=win_width, y=win_height, anchor='se')
master.update()
w = Label(master, text="Send and receive files easily", anchor='w')
w.config(font=('times', 32))
w.place(x=0, y=0, anchor='nw')
master.title("Bifrost v1.0")
self.img1 = PhotoImage(file="Images/logo.png")
self.img2 = PhotoImage(file="Images/magnifier.png")
frame.grid_columnconfigure(0, weight=1)
sendButton = Button(frame, image=self.img2)
sendButton.grid(row=0, column=1)
sendButton.image = self.img2

I am trying to migrate the code below (which is in tkinter) to pyqt. I am very new to pyqt. I could not get much details.

I have written this code but I am not sure how to make the grid and location for each widget in pyqt:

edit1 = QLineEdit()
edit2 = QLineEdit()
cb = QtGui.QCheckBox('Enable Test suite selection', self)
cb.move(150, 100)
#cb.stateChanged.connect(self.changeTitle)
cb2 = QtGui.QCheckBox('Send mail', self)
cb2.move(300, 100)
# cb2.stateChanged.connect(self.changeTitle)
hbox = QtGui.QHBoxLayout()
hbox.addStretch(1)
hbox.addWidget(SubmitButton)
hbox.addWidget(CancelButton)
hbox.addWidget(ResetButton)
hbox.addWidget(edit1)
hbox.addWidget(edit2)
hbox.addWidget(cb)
hbox.addWidget(cb2)

Thank you!
You can either do the designing part in your code or through a QT Designer which ships with PyQt4. and some examples can be found in the path C:\Python26\Lib\site-packages\PyQt4\examples and documentation in the path C:\Python26\Lib\site-packages\PyQt4\doc\html\modules.html if you are using windows. Hope this helps.
I have created a Form with labels and entries..but for some reason the entries are not being created,
peoplegui.py
from tkinter import *
from tkinter.messagebox import showerror
import shelve
shelvename = 'class-shelve'
fieldnames = ('name','age','job','pay')
def makewidgets():
global entries
window = Tk()
window.title('People Shelve')
form = Frame(window)
form.pack()
entries = {}
for (ix, label) in enumerate(('key',) + fieldnames):
lab = Label(form, text=label)
ent = Entry(form)
lab.grid(row=ix, column=0)
lab.grid(row=ix, column=1)
entries[label] = ent
Button(window, text="Fetch", command=fetchRecord).pack(side=LEFT)
Button(window, text="Update", command=updateRecord).pack(side=LEFT)
Button(window, text="Quit", command=window.quit).pack(side=RIGHT)
return window
def fetchRecord():
print('In fetch')
def updateRecord():
print('In update')
if __name__ == '__main__':
window = makewidgets()
window.mainloop()
When I run it the labels are created but not the entries.
You have forgetten to grid the entries.
