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:

• Define a class LabelEntry inherited from tk.Frame.

  class LabelEntry(tk.Frame):
      def __init__(self, parent, text, button=None):
          super().__init__(parent)
          self.pack(fill=tk.X)
  
          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)
          else:
              entry = tk.Entry(self)
              entry.pack(side=tk.LEFT, fill=tk.X, padx=5)
  

Usage:

• Define a class App inherit from tk.Tk.

  class App(tk.Tk):
      def __init__(self):
          super().__init__()
  
          self.title("Helper")
  
          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))
              else:
                  entries.append(LabelEntry(frame, field))
  

• Run the Application.

  if __name__ == "__main__":
      App().mainloop()
