How to keep tkinter button on same row as label and entry box

Question: How to keep tkinter button on same row as label and entry box

To reach this you have to pack the Entry and Button into a own Frame.

Note: Use always side=tk.LEFT to get the widgets in a row.

This example shows a OOP solution:
enter image description here

  • Define a class LabelEntry inherited from tk.Frame.

    class LabelEntry(tk.Frame):
        def __init__(self, parent, text, button=None):
            lbl = tk.Label(self, text=text, width=14, anchor="w")
            lbl.pack(side=tk.LEFT, padx=5, pady=5)
  • Condition: If a Button passed, create a new Frame to pack the Entry and Button.

            if button:
                frame2 = tk.Frame(self)
                frame2.pack(side=tk.LEFT, expand=True)
                entry = tk.Entry(frame2)
                entry.pack(side=tk.LEFT, fill=tk.X, padx=5)
                button.pack(in_=frame2, side=tk.LEFT, padx=5, pady=5)
                entry = tk.Entry(self)
                entry.pack(side=tk.LEFT, fill=tk.X, padx=5)


  • Define a class App inherit from tk.Tk.

    class App(tk.Tk):
        def __init__(self):
            frame = tk.Frame(self)
            frame.grid(row=0, column=0)
  • Loop the fields and create a LabelEntry object

            entries = []
            for field in 'Version', 'Database Name', 'CSV File':
                if field == 'CSV File':
                    button = tk.Button(text="Browse", command=self.callback)
                    entries.append(LabelEntry(frame, field, button))
                    entries.append(LabelEntry(frame, field))
  • Run the Application.

    if __name__ == "__main__":
