[Tkinter] Settting Default Values for grid

[deanhystad]

You could make a mixin class that adds the features you want for every widget and use that to make your own mixin versions of Label, Entry, Button...

Maybe a better solution for you is to write a Frame subclass that takes care of the layout responsibilities.

import tkinter as tk

class Grid(tk.Frame):
    '''A tk.Frame for lazy typers'''
    def __init__(self, parent=None, bg=None, **kwargs):
        if bg is None and parent is not None:
            bg = parent['bg']
        self.bg = bg
        super().__init__(parent, bg=self.bg, **kwargs)
        self.row = 0
        self.column = 0
        self.padx = 5
        self.pady = 5

    def add(self, widget, row=None, column=None, padx=None, pady=None, bg=None):
        if row is not None:
            self.row = row
        if column is not None:
            self.column = column
        if padx is not None:
            self.padx = padx
        if pady is not None:
            self.pady = pady
        if bg is not None:
            self.bg = bg
        widget['bg'] = self.bg
        widget.grid(row=self.row, column=self.column, padx=self.padx, pady=self.pady)
        return self

root = tk.Tk()
root.configure(bg='black')
grid = Grid(root, bg='black')
grid.pack()
grid.add(tk.Label(grid, text='Red', fg='blue'), row=0, column=0) \
    .add(tk.Label(grid, text='Blue', fg='green'), row=1) \
    .add(tk.Label(grid, text='Green', fg='red'), row=2) \
    .add(tk.Entry(grid, width=5), row=0, column=1, bg='yellow') \
    .add(tk.Entry(grid, width=5), row=1) \
    .add(tk.Entry(grid, width=5), row=2)

root.mainloop()

You could also repack everything after you create the widgets.

import tkinter as tk

root = tk.Tk()
root.configure(bg='black')

tk.Label(root, text='Red', fg='blue').grid(row=0, column=0)
tk.Label(root, text='Blue', fg='green').grid(row=1, column=0)
tk.Label(root, text='Green', fg='red').grid(row=2, column=0)
tk.Entry(root, width=5).grid(row=0, column=1)
tk.Entry(root, width=5).grid(row=1, column=1)
tk.Entry(root, width=5).grid(row=2, column=1)

for child in root.winfo_children():
    child.grid_configure(padx=5, pady=5)
    if isinstance(child, tk.Label):
        child['bg'] = 'black'
    elif isinstance(child, tk.Entry):
        child['bg'] = 'yellow'

root.mainloop()

Or you could set your own grid method.

import tkinter as tk

print(tk.Label.__bases__)
print(tk.Entry.__bases__)

root = tk.Tk()

def mygrid(self, row, column, padx=10, pady=5):
    self.grid(row=row, column=column, padx=padx, pady=pady)

setattr(tk.Widget, 'mygrid', mygrid)

tk.Label(root, text='Red', fg='blue').mygrid(row=0, column=0)
tk.Label(root, text='Blue', fg='green').mygrid(row=1, column=0)
tk.Label(root, text='Green', fg='red').mygrid(row=2, column=0)
tk.Entry(root, width=5).mygrid(row=0, column=1)
tk.Entry(root, width=5).mygrid(row=1, column=1)
tk.Entry(root, width=5).mygrid(row=2, column=1)

root.mainloop()

What I am trying to show is that if you have a regular pattern that you use when writing code, you can create tools that support that pattern. I don't write much tkinter code, and I think the tkinter object model is rather clunky, but it didn't take me long to come up with half a dozen ways to speed up how I could write tkinter code. You should review your code, look at your work patterns and think about what you could make that would speed up what you do.
