|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.|
|-dir path||Specifies the path name of the directory in which to store saved Post-it notes. If path 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 .postitnotes.|
|-sb||Enables scroll-bars. If specified, a scroll bar will be attached to each Post-it note.|
|-sv||Enables save-on-exit. When specified, this option tells xpostit 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.|
Xpostit uses several widget types to construct the objects 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.
Xpostit understands all of the core X Toolkit resource names and classes as well as those listed below, which are all of class XPostit.
.bufSize Specifies the size of the character buffer used to store a Post-it note. The default is 1024. .noteDir Specifies the path name of the directory in which to store saved notes. The default is .postitnotes. .saveNotes Controls the state of the save-on-exit option. The default is false. .scrollBar Controls placing scroll bars on Post-it notes. The default is false.
It is possible to rebind the mouse buttons in the Plaid widget to perform different functions by changing the widgets translations. The raise() action, normally bound to the left mouse button, raises all notes. The lower() action, normally bound to the middle mouse button, lowers all notes. The show() action, normally bound to the middle mouse button with the CTRL key, maps all unmapped notes. The hide() action, normally bound to the left mouse button with the CTRL key, unmaps all visible, non-iconic notes on the screen. The tearoff() action, normally invoked by dragging the left button off the Plaid widget, creates a new note. The tearoff action has an optional paramter indicating the size of the note to be created, e.g., tearoff(3x5) to create a 3-inch by 5-inch note. If no paramter is given, a 1.5-inch by 2-inch note will be created. The menu raising function, normally bound to the right mouse button, is performed by calling the actions XawPositionSimpleMenu(Menu) and MenuPopup(Menu). The quit() action, bound to the q and Q keys, is equivalent to selecting Exit from the menu.
Xpostit allows several operations to be performed from its control window. Clicking the left mouse button in the control window will cause all Post-it notes on the screen to be raised to the top. Clicking the middle mouse button in the control window will cause all Post-it notes on the screen to be lowered to the bottom. Clicking the left mouse button in the control window while holding down the CTRL key will cause all currently hidden notes to be mapped (shown). Clicking the middle mouse button in the control window while holding down the CTRL key will cause all notes on the screen which are not iconified to be unmapped (hidden). Pressing the left mouse button in the control window and dragging it outside the window will create a new note. Pressing the right mouse button in the control window raises the xpostit menu. Pressing the q or Q keys in the control window will exit the program.
The xpostit menu provides the following selections:
To select an item from the menu, drag the mouse cursor to that item and release the mouse button.
Create 1.5x2 Note Create a new Post-it note, 1.5 inches tall by 2 inches wide. The window will normally need to be positioned using the window manager. Create 2x3 Note Create a new Post-it note, 2 inches tall by 3 inches wide. Create 3x3 Note Create a new Post-it note, 3 inches square. Create 3x4 Note Create a new Post-it note, 3 inches tall by 4 inches wide. Create 3x5 Note Create a new Post-it note, 3 inches tall by 5 inches wide. Create 4x6 Note Create a new Post-it note, 4 inches tall by 6 inches wide. Raise All Notes Raise all Post-it notes to the top. This is equivalent to pressing the left mouse button in the control window. Lower All Notes Lower all Post-it notes to the bottom. This is equivalent to pressing the middle mouse button in the control window. Hide All Notes 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. Note: to hide a single note, you may use the window manager to send a WM_DELETE_WINDOW message to the note window. Under twm , this is done with the f.delete function. Show All Notes Map all Post-it notes, making them reappear if they were hidden. This is equivalent to pressing the left mouse button in the control window while holding down the CTRL key. Save All Notes Save all Post-it notes to disk files in the save directory. Exit Exit xpostit . If the -sv command line option was given, or the saveNotes resource is true , all Post-it notes will be saved to disk first.
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 xpostit, the Post-it note can be restored when you restart xpostit. (Post-it notes are also saved automatically (if saveNotes is true) if a SIGHUP, 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, or use the Alt-s keyboard sequence. The note will be saved as the file noten in your save directory, where n is some sequence number. NOTE: 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 xpostit 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. NOTE: 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, or enter the Alt-t keyboard sequence. 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. You can also simply press the Return key to change the title, or the Escape key to cancel the change.
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 arent all that accurate.
When the title of a Post-it note is changed, some window managers (notably twm ) 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 xpostit cannot be fully appreciated.
