winfo \- Return window-related information
.SH SYNOPSIS
\fBwinfo\fI option \fR?\fIarg ...\fR?
.BE
.SH DESCRIPTION
.PP
The \fBwinfo\fR command is used to retrieve information about windows
managed by Tk.  It can take any of a number of different forms,
depending on the \fIoption\fR argument.  The legal forms are:
.\" METHOD: atom
.TP
\fBwinfo atom \fR?\fB\-displayof \fIwindow\fR? \fIname\fR
.
Returns a decimal string giving the integer identifier for the
atom whose name is \fIname\fR.  If no atom exists with the name
\fIname\fR then a new one is created.
If the \fB\-displayof\fR option is given then the atom is looked
up on the display of \fIwindow\fR;  otherwise it is looked up on
the display of the application's main window.
.\" METHOD: atomname
.TP
\fBwinfo atomname \fR?\fB\-displayof \fIwindow\fR? \fIid\fR
.
Returns the textual name for the atom whose integer identifier is
\fIid\fR.
If the \fB\-displayof\fR option is given then the identifier is looked
up on the display of \fIwindow\fR;  otherwise it is looked up on
the display of the application's main window.
This command is the inverse of the \fBwinfo atom\fR command.
It generates an error if no such atom exists.
.\" METHOD: cells
.TP
\fBwinfo cells \fIwindow\fR
.
Returns a decimal string giving the number of cells in the
color map for \fIwindow\fR.
.\" METHOD: children
.TP
\fBwinfo children \fIwindow\fR
.
Returns a list containing the path names of all the children
of \fIwindow\fR. Top-level windows are returned as children
of their logical parents. The list is in stacking order, with
the lowest window first, except for Top-level windows which
are not returned in stacking order. Use the \fBwm stackorder\fR
command to query the stacking order of Top-level windows.
.\" METHOD: class
.TP
\fBwinfo class \fIwindow\fR
.
Returns the class name for \fIwindow\fR.
.\" METHOD: colormapfull
.TP
\fBwinfo colormapfull \fIwindow\fR
.
Returns 1 if the colormap for \fIwindow\fR is known to be full, 0
otherwise.  The colormap for a window is
.QW known
to be full if the last
attempt to allocate a new color on that window failed and this
application has not freed any colors in the colormap since the
failed allocation.
.\" METHOD: containing
.TP
\fBwinfo containing \fR?\fB\-displayof \fIwindow\fR? \fIrootX rootY\fR
.
Returns the path name for the window containing the point given
by \fIrootX\fR and \fIrootY\fR.
\fIRootX\fR and \fIrootY\fR are specified in screen units (i.e.
any form acceptable to \fBTk_GetPixels\fR) in the coordinate
system of the root window (if a virtual-root window manager is in
use then the coordinate system of the virtual root window is used).
If the \fB\-displayof\fR option is given then the coordinates refer
to the screen containing \fIwindow\fR;  otherwise they refer to the
screen of the application's main window.
If no window in this application contains the point then an empty
string is returned.
An empty string is also returned if the point lies in the title bar
or border of its highest containing toplevel in this application.
(Note that with some window managers the borders may be invisible.)
In selecting the containing window, children are given higher priority
than parents and among siblings the highest one in the stacking order is
chosen.
.\" METHOD: depth
.TP
\fBwinfo depth \fIwindow\fR
.
Returns a decimal string giving the depth of \fIwindow\fR (number
of bits per pixel).
.\" METHOD: exists
.TP
\fBwinfo exists \fIwindow\fR
.
Returns 1 if there exists a window named \fIwindow\fR, 0 if no such
window exists.
.\" METHOD: fpixels
.TP
\fBwinfo fpixels \fIwindow number\fR
.
Returns a floating-point value giving the number of pixels
in \fIwindow\fR corresponding to the distance given by \fInumber\fR.
\fINumber\fR may be specified in any of the forms acceptable
to \fBTk_GetScreenMM\fR, such as
.QW 2.0c
or
.QW 1i .
The return value may be fractional;  for an integer value, use
\fBwinfo pixels\fR.
.\" METHOD: geometry
.TP
\fBwinfo geometry \fIwindow\fR
.
Returns the geometry for \fIwindow\fR, in the form
\fIwidth\fBx\fIheight\fB+\fIx\fB+\fIy\fR.  All dimensions are
in pixels.
.\" METHOD: height
.TP
\fBwinfo height \fIwindow\fR
.
Returns a decimal string giving \fIwindow\fR's height in pixels.
When a window is first created its height will be 1 pixel;  the
height will eventually be changed by a geometry manager to fulfil
the window's needs.
If you need the true height immediately after creating a widget,
invoke \fBupdate\fR to force the geometry manager to arrange it,
or use \fBwinfo reqheight\fR to get the window's requested height
instead of its actual height.
.\" METHOD: id
.TP
\fBwinfo id \fIwindow\fR
.
Returns a hexadecimal string giving a low-level platform-specific
identifier for \fIwindow\fR.  On Unix platforms, this is the X
window identifier.  Under Windows, this is the Windows
HWND.  On the Macintosh the value has no meaning outside Tk.
.\" METHOD: interps
.TP
\fBwinfo interps \fR?\fB\-displayof \fIwindow\fR?
.
Returns a list whose members are the names of all Tcl interpreters
(e.g. all Tk-based applications) currently registered for a particular display.
If the \fB\-displayof\fR option is given then the return value refers
to the display of \fIwindow\fR;  otherwise it refers to
the display of the application's main window.
.\" METHOD: ismapped
.TP
\fBwinfo ismapped \fIwindow\fR
.
Returns \fB1\fR if \fIwindow\fR is currently mapped, \fB0\fR otherwise.
.\" METHOD: manager
.TP
\fBwinfo manager \fIwindow\fR
.
Returns the name of the geometry manager currently
responsible for \fIwindow\fR, or an empty string if \fIwindow\fR
is not managed by any geometry manager.
The name is usually the name of the Tcl command for the geometry
manager, such as \fBpack\fR or \fBplace\fR.
If the geometry manager is a widget, such as canvases or text, the
name is the widget's class command, such as \fBcanvas\fR.
.\" METHOD: name
.TP
\fBwinfo name \fIwindow\fR
.
Returns \fIwindow\fR's name (i.e. its name within its parent, as opposed
to its full path name).
The command \fBwinfo name .\fR will return the name of the application.
.\" METHOD: parent
.TP
\fBwinfo parent \fIwindow\fR
.
Returns the path name of \fIwindow\fR's parent, or an empty string
if \fIwindow\fR is the main window of the application.
.\" METHOD: pathname
.TP
\fBwinfo pathname \fR?\fB\-displayof \fIwindow\fR? \fIid\fR
.
Returns the path name of the window whose X identifier is \fIid\fR.
\fIId\fR must be a decimal, hexadecimal, or octal integer and must
correspond to a window in the invoking application.
If the \fB\-displayof\fR option is given then the identifier is looked
up on the display of \fIwindow\fR;  otherwise it is looked up on
the display of the application's main window.
.\" METHOD: pixels
.TP
\fBwinfo pixels \fIwindow number\fR
.
Returns the number of pixels in \fIwindow\fR corresponding
to the distance given by \fInumber\fR.
\fINumber\fR may be specified in any of the forms acceptable
to \fBTk_GetPixels\fR, such as
.QW 2.0c
or
.QW 1i .
The result is rounded to the nearest integer value;  for a
fractional result, use \fBwinfo fpixels\fR.
.\" METHOD: pointerx
.TP
\fBwinfo pointerx \fIwindow\fR
.
If the mouse pointer is on the same screen as \fIwindow\fR, returns the
pointer's x coordinate, measured in pixels in the screen's root window.
If a virtual root window is in use on the screen, the position is
measured in the virtual root.
If the mouse pointer is not on the same screen as \fIwindow\fR then
-1 is returned.
.\" METHOD: pointerxy
.TP
\fBwinfo pointerxy \fIwindow\fR
.
If the mouse pointer is on the same screen as \fIwindow\fR, returns a list
with two elements, which are the pointer's x and y coordinates measured
in pixels in the screen's root window.
If a virtual root window is in use on the screen, the position
is computed in the virtual root.
If the mouse pointer is not on the same screen as \fIwindow\fR then
both of the returned coordinates are \-1.
.\" METHOD: pointery
.TP
\fBwinfo pointery \fIwindow\fR
.
If the mouse pointer is on the same screen as \fIwindow\fR, returns the
pointer's y coordinate, measured in pixels in the screen's root window.
If a virtual root window is in use on the screen, the position
is computed in the virtual root.
If the mouse pointer is not on the same screen as \fIwindow\fR then
-1 is returned.
.\" METHOD: reqheight
.TP
\fBwinfo reqheight \fIwindow\fR
.
Returns a decimal string giving \fIwindow\fR's requested height,
in pixels.  This is the value used by \fIwindow\fR's geometry
manager to compute its geometry.
.\" METHOD: reqwidth
.TP
\fBwinfo reqwidth \fIwindow\fR
.
Returns a decimal string giving \fIwindow\fR's requested width,
in pixels.  This is the value used by \fIwindow\fR's geometry
manager to compute its geometry.
.\" METHOD: rgb
.TP
\fBwinfo rgb \fIwindow color\fR
.
Returns a list containing three decimal values in the range 0 to
65535, which are the
red, green, and blue intensities that correspond to \fIcolor\fR in
the window given by \fIwindow\fR.  \fIColor\fR
may be specified in any of the forms acceptable for a color
option.
.\" METHOD: rootx
.TP
\fBwinfo rootx \fIwindow\fR
.
Returns a decimal string giving the x-coordinate, in the root
window of the screen, of the
upper-left corner of \fIwindow\fR's border (or \fIwindow\fR if it
