;;; Commentary:
|
||||
|
||||
;; The standard library tooltip.el provides the function for displaying
|
||||
;; a tooltip at mouse position which allows users to easily show it.
|
||||
;; However, locating tooltip at arbitrary buffer position in window
|
||||
;; is not easy. This program provides such function to be used by other
|
||||
;; frontend programs.
|
||||
|
||||
;; This program is tested on GNU Emacs 22, 23 under X window system and
|
||||
;; Emacs 23 for MS-Windows.
|
||||
|
||||
;;
|
||||
;; Installation:
|
||||
;;
|
||||
;; First, save this file as pos-tip.el and byte-compile in
|
||||
;; a directory that is listed in load-path.
|
||||
;;
|
||||
;; Put the following in your .emacs file:
|
||||
;;
|
||||
;; (require 'pos-tip)
|
||||
;;
|
||||
;; To use the full features of this program on MS-Windows,
|
||||
;; put the additional setting in .emacs file:
|
||||
;;
|
||||
;; (pos-tip-w32-max-width-height) ; Maximize frame temporarily
|
||||
;;
|
||||
;; or
|
||||
;;
|
||||
;; (pos-tip-w32-max-width-height t) ; Keep frame maximized
|
||||
|
||||
;;
|
||||
;; Examples:
|
||||
;;
|
||||
;; We can display a tooltip at the current position by the following:
|
||||
;;
|
||||
;; (pos-tip-show "foo bar")
|
||||
;;
|
||||
;; If you'd like to specify the tooltip color, use an expression as:
|
||||
;;
|
||||
;; (pos-tip-show "foo bar" '("white" . "red"))
|
||||
;;
|
||||
;; Here, "white" and "red" are the foreground color and background
|
||||
;; color, respectively.
|
||||
|
||||
|
||||

If PIXEL-WIDTH and PIXEL-HEIGHT are given, this function assumes these

the tooltip won't disappear by sticking out of the display. By referring

the variable `pos-tip-upperside-p' after calling this function, user can

`top left corner of frame' represents the origin of `window-pixel-edges'

absolute coordinates. If a cons cell like (LEFT . TOP), specifies the

frame absolute location and makes the calculation slightly faster, but can

be used only when it's clear that frame is in the specified position. Users

can get the latest values of frame coordinates for using in the next call
|

by referring the variable `pos-tip-saved-frame-coordinates' just after

calling this function. Otherwise, FRAME-COORDINATES `relative' means return

pixel coordinates of the object relative to the top left corner of the frame.

This is the same effect as `pos-tip-use-relative-coordinates' is non-nil.
|

DX specifies horizontal offset in pixel.

DY specifies vertical offset in pixel. This makes the calculations done

|

|

Return pixel position of tooltip relative to top left corner of frame as
|
||||
a cons cell like (X . Y).
|
||||
|

TIP-COLOR is a face or a cons cell like (FOREGROUND-COLOR . BACKGROUND-COLOR)
|
||||
used to specify *only* foreground-color and background-color of tooltip. If
|
||||
omitted, use `pos-tip-foreground-color' and `pos-tip-background-color' or the
|
||||
foreground and background color of the `tooltip' face instead.
|

|

Omitting POS and WINDOW means use current position and selected window,
|
||||
respectively.
|

|

Automatically hide the tooltip after TIMEOUT seconds. Omitting TIMEOUT means
|

use the default timeout of 5 seconds. Non-positive TIMEOUT means don't hide

tooltip automatically.

WIDTH, if non-nil, specifies the width of filling each paragraph.
|

|

If FRAME-COORDINATES is omitted or nil, automatically obtain the absolute
|
||||
coordinates of the top left corner of frame which WINDOW is on. Here,
|
||||
`top left corner of frame' represents the origin of `window-pixel-edges'
|
||||
and its coordinates are essential for calculating the absolute coordinates
|
||||
of the tooltip. If a cons cell like (LEFT . TOP), specifies the frame
|
||||
absolute location and makes the calculation slightly faster, but can be
|
||||
used only when it's clear that frame is in the specified position. Users
|
||||
can get the latest values of frame coordinates for using in the next call
|
||||
by referring the variable `pos-tip-saved-frame-coordinates' just after
|
||||
calling this function. Otherwise, FRAME-COORDINATES `relative' means use
|
||||
the pixel coordinates relative to the top left corner of the frame for
|
||||
displaying the tooltip. This is the same effect as
|
||||
`pos-tip-use-relative-coordinates' is non-nil.
|
||||
|
||||
DX specifies horizontal offset in pixel.
|
||||
|
||||
DY specifies vertical offset in pixel. This makes the calculations done
|
||||
without considering the height of object at POS, so the object might be
|
||||
hidden by the tooltip.
