**DESCRIPTION**

The '''winfo()''' method is used to retrieve information about windows managed by Tkinter. It can take any of a number of different forms. The legal forms are:

window'''.winfo_cells()''' <<br>>
Returns a decimal string giving the number of cells in the color map for ''window''.

window'''.winfo_class()''' <<br>>
Returns the class name for ''window''.

window'''.winfo_depth()''' <<br>>
Returns a decimal string giving the depth of ''window'' (number of bits per pixel).

window'''.winfo_exists()''' <<br>>
Returns 1 if there exists a window named ''window'', an error is returned if no such window exists. 

window'''.winfo_fpixels('''number''')''' <<br>>
Returns a floating-point value giving the number of pixels in ''window'' corresponding to the distance given by ''number''. ''number' may be specified in any of the forms acceptable to '''Screen Units''', such as "2.0c" or "1i". The return value may be fractional; for an integer value, use ''winfo_pixels()''.

window'''.winfo_geometry()''' <<br>>
Returns the geometry for ''window'', in the form ''width'''''x'''''height'''''+'''''x'''''+'''''y''. All dimensions are in pixels. 

window'''.winfo_id()''' br>>
Returns a hexadecimal string giving a low-level platform-specific identifier for ''window''. 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 Tkinter.

window'''.winfo_ismapped()''' <<br>>
Returns '''1''' if ''window'' is currently mapped, ''0'' otherwise.

window'''.winfo_manager()''' <<br>>
Returns the name of the geometry manager currently responsible for ''window'', or an empty string if ''window'' is not managed by any geometry manager. The name is usually the name of the Tkinter method for the geometry manager, such as '''pack()''' or '''place()'''.

window'''.winfo_parent()''' <<br>>
Returns the path name of ''window'''s parent, or an empty string if ''window'' is the main window of the application.

window'''.winfo_pixels('''number''')''' <<br>>
Returns the number of pixels in window corresponding to the distance given by ''number''. ''Number'' may be specified in any of the forms acceptable to '''Screen Units''', such as "2.0c" or "1i". The result is rounded to the nearest integer value; for a fractional result, use '''winfo_fpixels()'''.

window'''.winfo_pointerx()''' <<br>>
If the mouse pointer is on the same screen as ''window'', returns the pointer's x coordinate, measured in pixels in the screen's root window.

window'''.winfo_pointerxy()''' <<br>>
If the mouse pointer is on the same screen as ''window'', returns a list with two elements, which are the pointer's x and y coordinates measured in pixels in the screen's root window.

window'''.winfo_pointery()''' <<br>>
If the mouse pointer is on the same screen as ''window'', returns the pointer's y coordinate, measured in pixels in the screen's root window.

window'''.winfo_reqheight()''' <<br>>
Returns a decimal string giving ''window'''s requested height, in pixels. This is the value used by ''window'''s geometry manager to compute its geometry. 

window'''.winfo_reqwidth()''' <<br>>
Returns a decimal string giving ''window'''s requested width, in pixels. This is the value used by ''window'''s geometry manager to compute its geometry.

window'''.winfo_rgb('''color''')''' <<br>>
Returns a list containing three decimal values in the range 0 to 65535, which are the red, green, and blue intensities that correspond to ''color'' in the window given by ''window''. ''Color'' may be specified in any of the forms acceptable for a color option.

window'''.winfo_rootx()''' <<br>>
Returns a decimal string giving the x-coordinate, in the root window of the screen, of the upper-left corner of ''window'''s border (or ''window'' if it has no border).

window'''.winfo_rooty()''' <<br>>
Returns a decimal string giving the y-coordinate, in the root window of the screen, of the upper-left corner of ''window'''s border (or ''window'' if it has no border). 

window'''.winfo_screencells()''' <<br>>
Returns a decimal string giving the number of cells in the default color map for ''window'''s screen. 

window'''.winfo_screendepth()''' <<br>>
Returns a decimal string giving the depth of the root window of ''window'''s screen (number of bits per pixel).

window'''.winfo_screenheight()''' <<br>>
Returns a decimal string giving the height of ''window'''s screen, in pixels.

window'''.winfo_screenmheight()''' <<br>>
Returns a decimal string giving the height of ''window'''s screen, in millimeters.

window'''.winfo_screenmwidth()''' <<br>>
Returns a decimal string giving the width of ''window'''s screen, in millimeters.

window'''.winfo_screenvisual()''' <<br>>
Returns one of the following strings to indicate the default visual class for ''window'' 's screen: '''directcolor''', '''grayscale''', '''pseudocolor''', '''staticcolor''', '''staticgray''', or '''truecolor'''. 

window'''.winfo_visual()''' <<br>>
Returns one of the following strings to indicate the visual class for ''window'': '''directcolor''', '''grayscale''', '''pseudocolor''', '''staticcolor''', '''staticgray''', or '''truecolor'''. 

window'''.winfo_visualid()''' <<br>>
Returns the X identifier for the visual for ''window''. 

window'''.winfo_visualsavailable('''[includeids=True]''')''' <<br>>
Returns a list whose elements describe the visuals available for ''window'' 's screen. Each element consists of a visual class followed by an integer depth. The class has the same form as returned by '''winfo_visual()'''. The depth gives the number of bits per pixel in the visual. In addition, if the '''includeids''' option is provided, then the depth is followed by the X identifier for the visual.

window'''.winfo_screenwidth()''' <<br>>
Returns a decimal string giving the width of ''window'''s screen, in pixels. 

window'''.winfo_x()''' <<br>>
Returns a decimal string giving the x-coordinate, in ''window'''s parent, of the upper-left corner of ''window'''s border (or ''window'' if it has no border).

window'''.winfo_y()''' <<br>>
Returns a decimal string giving the y-coordinate, in ''window'''s parent, of the upper-left corner of ''window'''s border (or ''window'' if it has no border).
