A tooltip window is a small X window displaying a string.
This is an internal function; Lisp code should call `tooltip-show'.
FRAME nil or omitted means use the selected frame.
PARMS is an optional list of frame parameters which can be used to
change the tooltip's appearance.
Automatically hide the tooltip after TIMEOUT seconds. TIMEOUT nil
means use the default timeout of 5 seconds.
If the list of frame parameters PARMS contains a `left' parameter,
display the tooltip at that x-position. If the list of frame parameters
PARMS contains no `left' but a `right' parameter, display the tooltip
right-adjusted at that x-position. Otherwise display it at the
x-position of the mouse, with offset DX added (default is 5 if DX isn't
specified).
Likewise for the y-position: If a `top' frame parameter is specified, it
determines the position of the upper edge of the tooltip window. If a
`bottom' parameter but no `top' frame parameter is specified, it
determines the position of the lower edge of the tooltip window.
Otherwise display the tooltip window at the y-position of the mouse,
with offset DY added (default is -10).
A tooltip's maximum size is specified by `x-max-tooltip-size'.
Text larger than the specified size is clipped. */)

based on the filetype of the visited file.

Emacs folder. You have to restart Emacs after installing new icons.
Example: Install an icon Gnus.tiff and execute the following code
(setq pgtk-icon-type-alist
(append pgtk-icon-type-alist
\\='((\"^\\\\*\\\\(Group\\\\*$\\\\|Summary \\\\|Article\\\\*$\\\\)\"

If this is nil, resize child frames like any other frames. This is the

however, may refuse to resize a child frame when Emacs is built with
GTK3. For those environments, the two settings below are provided.
If this equals the symbol 'hide', Emacs temporarily hides the child
frame during resizing. This approach seems to work reliably, may
however induce some flicker when the frame is made visible again.
If this equals the symbol 'resize-mode', Emacs uses GTK's resize mode to
always trigger an immediate resize of the child frame. This method is
deprecated by GTK and may not work in future versions of that toolkit.
It also may freeze Emacs when used with other desktop environments. It
avoids, however, the unpleasant flicker induced by the hiding approach.
This variable is considered a temporary workaround and will be hopefully
eliminated in future versions of Emacs. */);
