TCheckListBox.Columns property
The number of visible columns displayed on the control.
Declaration
property Columns:;Description
A list box can have multiple columns, as well as multiple rows. When
Columns is greater than 0 (zero), it specifies the number of
columns that are visible without horizontal scrolling. i. e. the width of a
single column becomes Width/Columns. Setting a new value for Columns causes
the widgetset class to be notified when a handle has been allocated for the
control.
The Columns property is not supported for the macOS Carbon, Cocoa, GTK2, QT4, QT5, and QT6 widgetsets.
This description is the one of StdCtrls.TCustomListBox.Columns.
