Erzeugen:
inputui = tkinter.Entry(self)

Setter/Getter:
self.var_name = tkinter.StringVar()
self.var_name.set("Ihr Name...")
self.inputui["textvariable"] = self.var_name

Alternative "Variablen:
self.var_inputfield = tkinter.IntVar()
self.var_inputfield = tkinter.DoubleVar()

Trotz "Variable" benötigt man ein try/except
try:
__zahl1 = self.var_inputfield.get()
except:
__messagebox.showerror( "Fehler", "Fehlerhafte Zahl")
__returnLayout-Manager:
self.inputui.pack oder self.textui.grid()

ActiveBackground:
self.inputui.config(activebackground= "yellow")
funktioniert nicht bei Tests

ActiveForeground:
self.input.config(activeforeground = "green")
funktioniert nicht bei Tests

Background:
self.inputui.config(background = "green")
self.inputui.config(background = "#FF0000")
self.inputui.config(bg = "#FF0000")

Foreground:
self.inputui.config(foreground="red")
self.inputui.config(fg="red")

Borderwidth:
self.inputui.config(borderwidth="2") #pixel

Borderwidth:
self.inputui.config(bd="2") # pixel

Height:
self.inputui.config(height="2") # Textzeilen

Justify:
self.inputui.config(justify("left")
self.inputui.config(justify("right")
self.inputui.config(justify("justify")
