All six sizes of Post-it notes may be displayed, edited, and saved to disk files. In addition, any on-screen note may be resized to any arbitrary size either when it is created or at a later time. When _x_p_o_s_t_i_t is first invoked, it creates a small window with a plaid background. This is the control window for _x_p_o_s_t_i_t. Additionally, if any notes were stored in the save directory (see below), these will be placed on the screen at their last locations. Each Post-it note, when created, makes another window on the screen. _X_p_o_s_t_i_t is controlled using the mouse buttons and a menu. The Post-it notes are controlled using buttons (Command widgets). OOOOPPPPTTTTIIIIOOOONNNNSSSS _X_p_o_s_t_i_t accepts all of the standard X Toolkit command line options along with the additional options listed below. ----bbbbssss _n_u_m_b_e_r Specifies the size of the character buffer in which to save each Post-it note. A note may not contain more than this number of characters, including newlines. The default is 1024. ----ddddiiiirrrr _p_a_t_h Specifies the path name of the directory in which to store saved Post-it notes. If _p_a_t_h begins with a `/' it is taken as-is; if it does not begin with a `/', the path is taken relative to the home directory. The named directory must already exist if notes are to be saved in it. The default is ._p_o_s_t_i_t_n_o_t_e_s. ----ssssbbbb Enables scroll-bars. If specified, a scroll bar will be attached to each Post-it note. ----ssssvvvv Enables save-on-exit. When specified, this option tells _x_p_o_s_t_i_t to save all Post-it notes to disk files when exiting. If not specified, notes will only be saved to disk files when saved manually by the user. WWWWIIIIDDDDGGGGEEEETTTT UUUUSSSSAAAAGGGGEEEE _X_p_o_s_t_i_t uses several widget types to construct the objects Page 1 (printed 4/30/98) XXXXPPPPOOOOSSSSTTTTIIIITTTT((((1111)))) XXXX11111111RRRR5555 ((((SSSSeeeepppptttteeeemmmmbbbbeeeerrrr 1111999999991111)))) XXXXPPPPOOOOSSSSTTTTIIIITTTT((((1111)))) it uses. The control window is a Plaid widget called ``Plaid''. The menu is a pop-up shell called ``Menu'' containing a SimpleMenu widget. Each Post-it note is a pop-up shell called ``PostItNote'', containing a Form widget called ``Note'' which contains a Text widget called ``NoteText'', and four Command widgets called ``Save'', ``Erase'', ``Destroy'', and ``Title''. The confirmation box is a pop-up shell called ``Confirm'', containing a Form widget called ``Buttons'' which contains two Command widgets called ``Confirm'' and ``Cancel''. The title-change box is a pop-up shell called ``Title'', containing a Dialog widget called ``Dialog''. RRRREEEESSSSOOOOUUUURRRRCCCCEEEESSSS _X_p_o_s_t_i_t understands all of the core X Toolkit resource names and classes as well as those listed below, which are all of class XXXXPPPPoooossssttttiiiitttt. ....bbbbuuuuffffSSSSiiiizzzzeeee Specifies the size of the character buffer used to store a Post-it note.

AAAACCCCTTTTIIIIOOOONNNNSSSS It is possible to rebind the mouse buttons in the Plaid widget to perform different functions by changing the widget's translations. The _r_a_i_s_e() action, normally bound to the left mouse button, raises all notes. The _l_o_w_e_r() action, normally bound to the middle mouse button, lowers all notes. The _s_h_o_w() action, normally bound to the middle mouse button with the CTRL key, maps all unmapped notes. The _h_i_d_e() action, normally bound to the left mouse button with the CTRL key, unmaps all notes on the screen. The menu raising function, normally bound to the right mouse button, is performed by calling the actions _X_a_w_P_o_s_i_t_i_o_n_S_i_m_p_l_e_M_e_n_u(_M_e_n_u) and _M_e_n_u_P_o_p_u_p(_M_e_n_u).

TTTTHHHHEEEE CCCCOOOONNNNTTTTRRRROOOOLLLL WWWWIIIINNNNDDDDOOOOWWWW _X_p_o_s_t_i_t allows six operations to be performed from its control window. Pressing the left mouse button in the control window will cause all Post-it notes on the screen to be raised to the top. Pressing the middle mouse button in the control window will cause all Post-it notes on the screen to be lowered to the bottom. Pressing the left mouse button in the control window while holding down the CTRL key will cause all notes to be mapped (shown). Pressing the middle mouse button in the control window while holding down the CTRL key will cause all notes on the screen to be unmapped (hidden). Pressing the right mouse button in the control window raises the _x_p_o_s_t_i_t menu. Pressing the ``q'' or ``Q'' keys in the control window will exit the program. TTTTHHHHEEEE MMMMEEEENNNNUUUU The _x_p_o_s_t_i_t menu provides the following selections: CCCCrrrreeeeaaaatttteeee 1111....5555xxxx2222 NNNNooootttteeee Create a new Post-it note, 1.5 inches tall by 2 inches wide.

HHHHiiiiddddeeee AAAAllllllll NNNNooootttteeeessss Unmap all Post-it notes, making them disappear from the screen. This is equivalent to pressing the middle mouse button in the control window while holding down the CTRL key. SSSShhhhoooowwww AAAAllllllll NNNNooootttteeeessss Map all Post-it notes, making them reappear if they were hidden.

SSSSaaaavvvveeee AAAAllllllll NNNNooootttteeeessss Save all Post-it notes to disk files in the save directory. EEEExxxxiiiitttt Exit _x_p_o_s_t_i_t . If the ----ssssvvvv command line option was given, or the ssssaaaavvvveeeeNNNNooootttteeeessss resource is ttttrrrruuuueeee ,,,, all Post-it notes will be saved to disk first. To select an item from the menu, drag the mouse cursor to that item and release the mouse button. TTTTHHHHEEEE PPPPOOOOSSSSTTTT----IIIITTTT NNNNOOOOTTTTEEEE Each Post-it note is made up of five parts (plus an optional scroll bar): a text window where the text of the note is stored, and four buttons labeled ``Save'', ``Erase'', ``Destroy'', and ``Title''. The title of a Post-it note, which will be displayed by most window managers in both a title bar and the icon name area, is by default the string ``PostItNote #'' followed by a small integer, the number of the note. The procedure for changing this title to something more meaningful is described below. To enter text into a Post-it note, simply move the mouse cursor into the text window and start typing. Since the text window is actually a Text widget, all the Text widget translations are accepted. Essentially, this means you can use most of the EMACS control keys in the window. Additionally, the various mouse buttons used for manipulating the selections and cut buffer are understood. After entering text in the Post-it note, you may wish to save the note in a disk file. This way, if the machine goes down, or if you exit _x_p_o_s_t_i_t, the Post-it note can be restored when you restart _x_p_o_s_t_i_t. (Post-it notes are also saved automatically (if ssssaaaavvvveeeeNNNNooootttteeeessss is true) if a SIGHUP, Page 4 (printed 4/30/98) XXXXPPPPOOOOSSSSTTTTIIIITTTT((((1111)))) XXXX11111111RRRR5555 ((((SSSSeeeepppptttteeeemmmmbbbbeeeerrrr 1111999999991111)))) XXXXPPPPOOOOSSSSTTTTIIIITTTT((((1111)))) SIGINT, SIGTERM, or SIGQUIT signal is received.) To save the note to a disk file, move the mouse cursor to the button labeled ``Save'' and press the left mouse button. The note will be saved as the file ``note_n'' in your save directory, where _n is some sequence number. NNNNOOOOTTTTEEEE: it is important to remember that until you have pressed the ``Save'' button, the data stored in the Post-it note is not saved on disk and can be lost if the system goes down or _x_p_o_s_t_i_t exits. To erase the entire contents of the text window, you can press the left mouse button in the ``Erase'' button. This will bring up a confirmation window, which has two buttons labeled ``Confirm'' and ``Cancel''. If you press the ``Confirm'' button, the text will be erased. If you press the ``Cancel'' button, the operation is canceled, and nothing will happen. NNNNOOOOTTTTEEEE: erasing the text in the window does not affect any contents of the note you have saved on disk unless you press the ``Save'' button again. To destroy a Post-it note, getting rid of its window on the screen and the disk file it is saved in, move the mouse cursor to the ``Destroy'' button and press the left mouse button. This will bring up a confirmation window as described above. If you confirm the operation, the Post-it note will disappear from the screen and the disk file it was saved in will be deleted. To change the title of a Post-it note, both in any title bar on the window as well as in the icon for the note, move the mouse cursor to the ``Title'' button and press the left mouse button. This will bring up a dialog box with the current title in it. Change or modify the title, and press the ``Okay'' button with the mouse to change the title, or press the ``Cancel'' button to discard the change. SSSSEEEEEEEE AAAALLLLSSSSOOOO X(1) BBBBUUUUGGGGSSSS The sizes of the Post-it notes are only as accurate as the display dimension and resolution returned by the server. On the Sun server and possibly others, this means they aren't all that accurate. When the title of a Post-it note is changed, some window managers (notably _t_w_m ) will not make the change in the icon name, since they only look up this data when a window is mapped. This can be ``fixed'' by unmapping all notes and mapping them again. Without a color display for canary yellow notes and red plaid, the aesthetic value of _x_p_o_s_t_i_t cannot be fully Page 5 (printed 4/30/98) XXXXPPPPOOOOSSSSTTTTIIIITTTT((((1111)))) XXXX11111111RRRR5555 ((((SSSSeeeepppptttteeeemmmmbbbbeeeerrrr 1111999999991111)))) XXXXPPPPOOOOSSSSTTTTIIIITTTT((((1111)))) appreciated.
