Greatis WinDowse from Greatis Software is an extremely convenient tool for obtaining necessary technical information about any window. Place a mouse cursor on a window, and WinDowse will show all parameters of the window, window class, parents and children including:

"Window" tab
- text or caption
- process ID
- exe filename
- application instance
- window handle
- parent window handle
- window function address
- window menu handle
- coordinates in parent
- coordinates in screen
- window size
- window client area size
- window style and extended style

"Class" tab
- class name
- class function address
- icon and small icons handles
- cursor handle
- background brush handle
- module handle
- class style.

"Parents" tab
- list of parent hierarchy

"Children" tab
- list of children of current window

"Graphics" tab
- absolute (screen) cursor position
- relative cursor position on window coordinates
- relative cursor position on window client area coordinates
- color of the pixel under mouse cursor
- screen capture tools: display, zoom, copy, save

All parameters can be shown in hexadecimal, decimal or binary formats. Upon activation, WinDowse displays a continous readout as the user moves the mouse about the screen - switching back and forth between separate or nested windows. At any time the continuous readout can be frozen by a click of the mouse, and the data for that window studied in detail. WinDowse also allows results to be copied directly to the clipboard. Each field of the analysis is supplied with context-sensitive help explaining "what is", and containing references to WinAPI functions.
