example in gui.py missing queue function. ManagedWindow.queue not implemented

[TedKus]

python .\gui.py
Traceback (most recent call last):
  File "C:\Users\user\AppData\Roaming\Python\Python311\site-packages\pymeasure\display\windows\managed_window.py", line 491, in _queue
    self.queue()

NotImplementedError: Abstract method ManagedWindow.queue not implemented

MainWindow class needs a queue function for the gui button:
Added two imports, tempfile and Results.
Added MainWindow.queue

This file is substantially similar to console.py. Perhaps consider merging?
I've put the entire corrected file here:

This example demonstrates how to make a graphical interface, and uses
a random number generator to simulate data so that it does not require
an instrument to use.

Run the program by changing to the directory containing this file and calling:

What did you change?
A PR makes it clearer, what line(s) you changed.

Thanks for raising that bug.

I actually think something else is the matter: the v: latest documentation reflects the latest version on github, not the latest release; I think for the latest release, you need to look at v: stable. You can switch between the two versions in the bottom left corner.

The absence of the queue method in the ManagedWindow example is by design: as per PR #964, it is not needed anymore to have a boilerplate queue method (provided you do not set enabled_file_input to False).
