tab_truncate

Normally, any text that is too wide to fit in a column, will be spread across multiple columns and pushes any text which appears to the right further in the same row, sometimes providing very inconvenient visual effects and artefacts.

If tab_truncate attribute is set to true, text will be restricted to its own column only and grid lines will be displayed between the columns and rows; using false provides standard behaviour.

Truncated text can be revealed by dragging the grid lines between the columns - dragging the column grid lines is a BricsCAD only feature.
Combined with the special label handling for listboxes (having true column headers), a 'normal' DCL listbox becomes very comfortable.

special behaviour applies : listboxes only, otherwise ignored
