Arguments: standard-object
Returns or sets with setf the value of the tabs property of the argument. The value of this property is a list of distances (in pixels) from the left edge of the control. These are spacing guides for text whenever tab characters appear in a displayed string. For list controls, these values specify the location of columns when the list control displays multiple columns.
tabs is a property of the outline, dropping-outline, multi-item-list, single-item-list, multi-line-editable-text, and text-edit-pane classes.
text-edit-pane and rich-edit control arguments: when standard-object
is a text-edit-pane (or a rich-edit-pane, which
is a subclass of text-edit-pane), or a rich-edit control, tabs returns a
list of tabstop positions, indicating to where text will move
rightward wherever a tab character appears in the text. The values are
specified in points, where 0 indicates the interior left edge of the
text-edit-pane and 72 indicates one inch to the right (since a point
is one 72nd of an inch). The values are ordered from left to right.
(setf tabs) for a text-edit-pane and for a rich-edit control
establishes the set of tabstop positions for text-edit-pane,
indicating to where text will move rightward wherever a tab character
appears in the text. value should be a list of tabstop positions
ordered from left to right and specified in points, where 0 indicates
the interior left edge of the text-edit-pane (or left margin of the
printed output) and 72 indicates one inch to the right (since a point
is one 72nd of an inch).
If the rich-edit has its tabstop property turned off (the default), then pressing the tab key will insert a tab character into the control's text. If the tabstop property is turned on, then pressing the tab key will move the focus to the next widget, and control-semicolon must be pressed in order to insert a tab character interactively. A comtab or virtual-key-down method could be supplied to make some other keychord insert a tab-character by doing something like
(write-char #\tab rich-edit-pane)
