-
- PMTREE is an application for examination of and interaction with the
- windows of an OS/2 system. It is a 32-bit Presentation Manager
- application that will run on OS/2 2.0, but not previous versions of
- OS/2.
-
- All activity centres around a graphical display of a window hierarchy
- shown in the client area of the main window. A window is represented at
- the top left by a rectangle accompanied by descriptions of various
- features of the window. Its immediate children are represented by a
- series of rectangles arranged in a column to the right of this 'head'
- window. Similarly their children may be represented to the right of
- their representations, for as many levels as the hierarchy of windows
- extends. Different window classes are represented in different colours.
- The user is also able to select any one of the system defined window
- styles from the menu. Subsequently all windows which have that style
- flag set will be represented in reverse colours.
-
- Extra information is displayed under the head window representation.
- This comprises the window id, the process and thread ids, the owner
- window (if there is one), the window position and size, the window style
- (broken into the constituent flags), the minimise and restore positions
- and sizes (where applicable), the window procedure address and, for menu
- windows the item ids contained in the menu (and item texts for the
- PMTREE process and when the Extensions option has been selected), for
- frame windows the FF_ flag names and accelerator table handle and table
- contents, and for listboxes and combo boxes the number of items in a
- listbox.
-
- For convenience the tree may be simplified by displaying only one level
- of children. Alternatively the user can disable branches of the tree
- by double clicking the 'manipulation button' of the mouse over the
- representation of a window. In both cases uncharted branches will be
- indicated by "+ + +".
-
- The user may choose to bring up a dialog to change various values
- associated with any window (size, position, window text, style, id,
- parent, owner). These options should be used with care. There are many
- ways to hang the system and it is not practical to try to detect all
- such cases and disallow them.
-
- The user may also bring up another dialog that allows a large number of
- different messages to be sent, posted or broadcast to the window. These
- messages can pass pointers to data including text strings in their
- parameters.
-
- /n, /x and /r are command line parameters that will bring the main window
- up minimised, maximised and restored respectively. Otherwise PMTREE will
- reuse the position and size that it occupied when last used. PMTREE can
- remember settings, window selection and window position across
- invocations.
-
- The application is supplied with help that describes in fuller detail
- how to use the menu options supplied and how to use PMTREE to interact
- with the windows of the Presentation Manager system.
