From a clue in another thread, Claude 2, Bard, and finally the awesome paid version of GPT-4, I produced this sweet function:
GPT-4 summary: The code defines a Python function,
multi_select_dialog, which creates a custom Windows Forms dialog. This dialog features a filterable ListView with multi-select checkboxes. The dialog is resizable, and it includes “Select All” and “Select None” buttons for easy manipulation of the checkboxes. The ListView and buttons are anchored to dynamically adjust their positions when the form is resized. The function returns a list of selected items when the user clicks “OK” and an empty list if “Cancel” is clicked. The dialog also includes a separator line for visual separation of the action buttons. The code leverages the .NET framework through Python’s clr library.
