Tkinter delete not working on referenced entry when referenceing lenth of entry

I have a tkinter window class that I've made and my delete function is not working properly.
my_window = tk.Tk()
class QuoteForm():
def __init__(self,master):
self.file_data = ''
self.master = master
self.master.rowconfigure(0, weight=1)
self.master.rowconfigure(1, weight= 1)
self.master.rowconfigure(2, weight = 1)
master.geometry('600x400')
master.resizable(False,False)
#create the frames
self.directory_frm = tk.Frame(master=master)
self.directory_frm.grid(row=0) #this is the frame for the directory
self.add_on_frm = tk.Frame(master=master)
self.add_on_frm.grid(row=1) #this is the frame for add-ons input
self.button_frm = tk.Frame(master=master)
self.button_frm.grid(row=2) #this is the frame for
#creates buttons, entries, labels
self.load_directory_frame() #creates and grids the directory button
self.load_add_on_frame() #creates and grids the entry buttons and labels
self.load_button_frame() #creates and grids the buttons
my_window.mainloop()
def load_add_on_frame(self):
vcmd = (self.master.register(self.validate_ent), '%S')
#create inputs and labels for add-ons
self.trip_ent = tk.Entry(master=self.add_on_frm,validate = 'key', validatecommand = vcmd, name='trip_ent')
self.trip_ent.grid(column= 1, row = 0)
self.raw_cutouts_ent = tk.Entry(master=self.add_on_frm,validate = 'key', validatecommand = vcmd)
self.raw_cutouts_ent.grid(column= 3, row = 0)
def clear_entries(self):
entries = (self.trip_ent, self.raw_cutouts_ent) #list of entries to loop (there are a total of 12 in the actual code)
for entry in entries:
entry.delete(0,len(entry.get())) #this is where the trouble seems to happen
new_quote = QuoteForm(my_window)
My problem is that the on the second to last line of code (starting with 'entry.delete')
Typically you would do 'entry.delete(0,END)' but because entry is a variable the code won't run with END.
'END' is an invalid index, and 'end' just does the same as pulling the length, and so i tried to make it dynamic by making the 'end' the length of whatever is in the entry.
When i do that however, it deletes nothing [i also tried forcing it with int(len(entry.get()))]. If i manually enter an integer it will delete everything up to that integer, including if it's the same as the length of that entry, and I put breaks to confirm that i'm getting an int return and I am.
I realize i could just write a line of code to delete each entry individually, but there's a totaly of 12 and I would like to clean it up.
I'm adding the full code to be able to run below

It's all about yourvalidate_ent function. Only when it returns true then your entry text can change. While typing tkinter just sent single chars like '1','2','a'. Even when you remove with backspace, this function gets the character you are trying to remove. However when you try to clear it function gets as an input whole string like '123543123'. This is not takes place inside r'[0-9]' reguler expression and you return false so tkinter denies removing it.
There is two simple solution to fix this.
First one add another condition for longer input like:
def validate_ent(self,input):
if not input:
return True
elif re.fullmatch(r'[0-9]',input):
return True
if(len(input)>2):
return True
return False
However I do not recommend this one because if someone copy paste longer inputs then it can write letters inside entry boxes.
def validate_ent(self,input):
if not input:
return True
elif re.fullmatch(r'[0-9]*',input):
return True
return False
In here we added a asteriks to reguler expression. Now it's accepting numbers bigger then 9. Now people can also paste numbers that fits into this rule. Also removing works as expected!

How do you query an object inside of a text field, to do something with it?

I would like to know how to query a selection entered into a text field group, so I can do something with it. I have created a window to just translate an object that I loaded in the text field. The error is that cont is not defined.

Create any object you like, loaded into the text field and then try to translate with buttons.

You have several problems in your code.
In the translate commands you always use cont[0]. cont is only used in the function set_selected_name() and is a local variable what means it is deleted as soon as the function is completed.
You can use a string as command in the button command, but this only works with static values. You should use lambdas to use functions with arguments.
The cont Problem can be solved by using a global variable, but it shouldn't since global variables are the source of all evil. A much more elegant way would be to enclose you UI in one python class and use instance variables to get the selection.

I have adjusted the code to add the class as you recommended but still having the same issue. By not using the quotes in the button command I get this error when I try to run the script, instead of getting it when I press the button.
Error: NameError: file line 28: name 'translate_x' is not defined
Can you please write a workable version, or place a link from the internet that shows a method using the class and calling methods using buttons? Nothing I have found from my internet search has anything like this and I'm just guessing where thigs should go.
import maya.cmds as cmds
import maya.mel as ml

Why wont my code return a value for the data input into a tkinter text box

I have written this code and for some reason it refuses to return any sort of value or input for slef.REV when used in the function post(self) however it will return a value when I try and return a value in the getlen() function which is used to reurn the number of characters in the review.I dont have this problem for any other variables that I retrieve data from within this class. Below is the relevant code, any help would be appreciated. the lines where this problem occures is the first functio calld post(lines 1-5) and 4 lines up from the bottom

You can use Entry instead and use a StringVar
v = StringVar() # Create StringVar
reviewbox = Entry(frame_4, width = 100, height = 12, textvariable = v) # Create Entry widget
reviewbox.place(x = 10, y = 500) # Place Entry widget
self.REV = v.get() # Get contents of StringVar

The line self.REV = reviewbox.get('1.0',END) is being called about a millisecond after creating the text widget. The user will not even have seen the widget yet, much less have had time to type in it.
You can't call the get() method until after the user has had a chance to enter data, such as inside the post method.
def post(self):
MovieID = self.MovID
REV = reviewbox.get("1.0", "end")
AddReview(conn,cursor,Add_Review,MovieID,REV)
print(REV)

When you call On_animation_button() manually, your frame is not actually shown yet, even though you had called Show() on it because, at least with X11, showing happens asynchronously. So you need to delay calling it until later. This can be done by e.g. binding a lambda doing this to EVT_SIZE event (because by the time you get it, the window is already initialized) or just by using CallAfter().

Get ItemWidget from QTreeWidget on DoubleClick event

I created a QTreeWidget now when i click on an item, i want to get the widget data.
I fill my QTreeWidget that way :
def addNodeToTreeview(self, data):
self.panelInfoPatientUi.treeWidgetDevices.clear()
for item in data:
mainWidgetItem = QtGui.QTreeWidgetItem(self.panelInfoPatientUi.treeWidgetDevices)
widgetContainer = QtWidgets.QWidget()
widgetContainer.setObjectName("widgetContainer")
deviceWidget = Ui_DeviceListviewWidget()
deviceWidget.setupUi(widgetContainer)
deviceWidget.labelSerialNumber.setText(item.serialNumber)
deviceWidget.labelModel.setText(item.model)
deviceWidget.labelInstallationDate.setText(item.installDate)
mainWidgetItem.setSizeHint(0, widgetContainer.sizeHint())
self.panelInfoPatientUi.treeWidgetDevices.addTopLevelItem(mainWidgetItem)
self.panelInfoPatientUi.treeWidgetDevices.setItemWidget(mainWidgetItem, 0, widgetContainer)
for files in item.listFile:
#Files
fileWidgetItem = QtGui.QTreeWidgetItem(mainWidgetItem)
widgetContainerFiles = QtWidgets.QWidget()
widgetContainerFiles.setObjectName("widgetContainerFiles")
fileWidget = Ui_FileListWidgetItem()
fileWidget.setupUi(widgetContainerFiles)
fileWidgetItem.setText(0, "BLABLBALA")
fileWidget.labelFileName.setText(files.fileName)
fileWidget.labelDateFile.setText(files.dateFile)
fileWidgetItem.setSizeHint(0, widgetContainerFiles.sizeHint())
mainWidgetItem.addChild(fileWidgetItem)
self.panelInfoPatientUi.treeWidgetDevices.setItemWidget(fileWidgetItem, 0, widgetContainerFiles)
i connect the widget that way :
def connectSignalTreeWidget(self):
self.view.panelInfoPatientUi.treeWidgetDevices.itemDoubleClicked.connect(self.testest)
and when i receive the Click event i can't access to my widget i tried several way :
def testest(self, item, col):
print(self.view.panelInfoPatientUi.treeWidgetDevices.itemWidget(item, 0))
#print([method for method in dir(item) if callable(getattr(item, method))])
#print(str(item.ItemType()))
#print(str(item.text(col)))
#print(str(item.child(0)))
#print(str(item.childCount()))
#print(str(item.child(1).text(0)))
#print(str(self.view.panelInfoPatientUi.treeWidgetDevices.currentItem()))
# titi = .itemWidget(item, columnIndex)
# print(str(titi))
# titi.text(0)
# titi.data()
#print(str(titi.labelFileName.text()))
'''selectedItems = self.view.panelInfoPatientUi.treeWidgetDevices.selectedItems()
for selectedItem in selectedItems:
print(str(selectedItem.text(0)))
print(str(selectedItem.text(1)))
print(str(selectedItem.text(2))) '''
'''
print(item.data(1, 0))
print("column count " + str(data.columnCount()))
print("AHYAAAAAAAAAA")'''
As i use "setItemWidget" method i expect to get a getItemWidget method and retreive data from it but no. How can i access to fileWidget.labelFileName ?
Thanks

I found the solution :
I changed my creation methode :
def addNodeToTreeview(self, data):
self.panelInfoPatientUi.treeWidgetDevices.clear()
for item in data:
mainWidgetItem = QtGui.QTreeWidgetItem(self.panelInfoPatientUi.treeWidgetDevices)
widgetContainer = QtWidgets.QWidget()
widgetContainer.setObjectName("widgetContainer")
deviceWidget = Ui_DeviceListviewWidget()
deviceWidget.setupUi(widgetContainer)
deviceWidget.labelSerialNumber.setText(item.serialNumber)
deviceWidget.labelModel.setText(item.model)
deviceWidget.labelInstallationDate.setText(item.installDate)
mainWidgetItem.setSizeHint(0, widgetContainer.sizeHint())
self.panelInfoPatientUi.treeWidgetDevices.addTopLevelItem(mainWidgetItem)
self.panelInfoPatientUi.treeWidgetDevices.setItemWidget(mainWidgetItem, 0, widgetContainer)
for files in item.listFile:
#Files
fileWidgetItem = QtGui.QTreeWidgetItem(mainWidgetItem)
widgetContainerFiles = QtWidgets.QWidget()
widgetContainerFiles.setObjectName("widgetContainerFiles")
widgetContainerFiles.ui = Ui_FileListWidgetItem()
widgetContainerFiles.ui.setupUi(widgetContainerFiles)
widgetContainerFiles.ui.labelFileName.setText(files.fileName)
widgetContainerFiles.ui.labelDateFile.setText(files.dateFile)
fileWidgetItem.setSizeHint(0, widgetContainerFiles.sizeHint())
mainWidgetItem.addChild(fileWidgetItem)
self.panelInfoPatientUi.treeWidgetDevices.setItemWidget(fileWidgetItem, 0, widgetContainerFiles)
and i can get my data like that :
def testest(self, item, col):
print(str(item.treeWidget().itemWidget(item, col).ui.labelFileName.text()))
