Arguments: text-edit-widget-or-window
Returns a value indicating the extra empty space that will appear in a
text-editing control between its left and right borders and its text.
The setf of this
function may be called to change the margins at any time, and the
margins may be specified initially as the value of the
:text-edit-margins
initarg when creating the
control. The control will be redrawn as needed automatically whenever
these margins are changed.
text-edit-widget-or-window may be either an
editable-text
or multi-line-editable-text
widget or
an editable-text-pane
or text-edit-pane
window.
For the widgets, text-edit-margins appears as a property in the
inspector when laying out widgets interactively on a form.
The value that is returned from text-edit-margins or passed to
(setf text-edit-margins) may be
either nil
to indicate default margins, or a
non-negative integer to specify the same margin for both sides, or a
list of two non-negative integers to specify individual margins for
the left and right sides (in that order). The values are measured in
pixels, and are added to any default margins that are built into the
control. nil
and 0 and (0 0) are equivalent
values that indicate default margins. The initial value is nil
.
This function determines how a text-editing control lays out its
interior, and so is distinct from other margin-related facilities that
affect how stream output is printed, such as the Common Lisp variable
*print-right-margin*
and the Common
Graphics functions left-margin, top-margin, right-margin, and bottom-margin.
Calling (setf text-edit-margins) will have an effect on GTK only on multi-line controls.
