Arguments: text-edit-pane
Returns the current indentation of the first line of a paragraph of
text in a text-edit-pane
, or the indentation
indicated by the corresponding upper-left slider of a rich-edit-ruler
.
This generic function may be called either on a text-edit-pane
(typically a rich-edit-pane
) or on
a rich-edit-ruler
. The methods
behave somewhat differently: for a text-edit-pane, body-left-indentation is relative
to top-left-indentation to match the
rich text specification and the Microsoft rich edit control; for a
rich-edit-ruler, top-left-indentation is instead
relative to body-left-indentation to match the
intuitive practice of moving the overall indentation of one or more
paragraphs without changing the relative indentation of the first line
of each paragraph.
The text-edit-pane
method returns the
left indentation of the first line of the paragraph that contains the
text-edit-pane's text cursor (or the first paragraph partly or wholly
contained in the selected text, if any). This value is measured in
points, and is measured rightward from the interior left of the
text-edit-pane. A point is one seventy-second of an inch.
The setf method for text-edit-pane
sets the indentation
of the first line of the paragraph that contains the text cursor (or
all paragraphs that are partly or wholly selected, if any). Since the
body-left-indentation of a
text-edit-control is relative to this position, the body indentation
will change by the same amount. If there is a rich-edit-ruler
associated with the
text-edit-pane (see the function ruler), then the rich-edit-ruler's
indentation will be automatically modified to match.
The rich-edit-ruler
method returns the
position of the slider at the upper left of the ruler, measured
rightward in points from the position of the lower-left slider for
body-left-indentation.
The setf method for rich-edit-ruler
moves the
upper-left slider of the ruler to the specified position relative to
the lower-left slider. The slider will be constrained at position 0
(the leftmost position) if an attempt is made to move it to a negative
position. If there is a text-edit-pane
associated with the
ruler (see the function rich-edit), then the paragraph in
the text-edit-pane that contains the text cursor (or all paragraphs
that are partly or contained in the selected text, if any) will be
automatically modified to match (by modifying indentation of only the
first line of each selected paragraph).
To apply this function to a rich-edit
control, first apply
window to the
control to obtain a rich-edit-pane
to pass to this
function.
To read or modify multiple paragraph attributes of a text-edit-pane at once, see get-paragraph-format or set-paragraph-format.
