Feat : truncate overflowing content of TextEntry and TextUpdate, append ellipsis

[gabriel-desmarchelier]

If the content of a TextEntry or a TextUpdate is wider than the width of the field, the displayed value is truncated without any warning. Our operators are quite frequently misled by this lack of accuracy.

What it currently looks like with various display formats :

In this PR, I created a truncateText method that truncates the actual value and appends (or prepends, depending on horizontal alignment) an ellipsis. The result is stored in the truncated_value_text string.

I use the focusProperty listener to switch the displayed text between the full and the truncated ones : whenever the widget gets the focus, one must be able to read and edit the actual value.

The behavior of the multi-line TextEntry and of the interactive TextUpdate remains unchanged : scrollbars are to be used.

The result :

A bob file to play with the various configurations :
text_field_truncation.tar.gz

This could also be implemented for Spinner widget.
