xcalendar [month [year]]
The xcalendar is a simple interactive calendar program with a notebook capability. It is built on the X Toolkit and the Athena Widgets.
If month and year are not provided on the command line they are assumed to be current.
Clicking the left mouse button on a day will start a text editor. You can edit and save a text.This text will be associated with the day. You can later on read and edit this text when you open the editor for the same day. The text is saved in a file in the directory ~/Calendar. The editor lets you also clear an entry associated with a particular day. You can also scroll through days while in the editor by clicking on the arrows on either side of the date label. If an already open day is scrolled to, an appropriate message is displayed and the editor is brought upin read only mode.
It is also possible to scroll through months in the main window by clicking on the arrows on either side of the current date label.
You can highlight all entries in a month by invoking the function ShowEntries. By default this function is called when the left mouse button is pressed in the title window (where month and a year are displayed). Pressing again the same button will unhighlight the entries.
To remove all entries in a particular month you have to use your system's commands. The naming scheme for the files makes it easy : the command "rm ~/Calendar/xc*sep1988 " on UNIX(TM) will remove all entries from september 1988. The facility to do that from the xcalendar should be provided.
One can imagine many other useful features. For example automatic parsing of the current day entry in search for appointments to trigger alarms (reminders) at the approriate time. Well, maybe one day...
The resource data base lets you alter the visual appearance of the program. You can change fonts, border widths, labels, and other resources used by widgets. One use of this facility is to change names of week days and months.
Here are the names of widgets you can use to set various resources:
XCalendar - class of the application xcalendar - top level pane controls - control panel quitButton - quit button helpButton - help button date - date label calendar - calendar pane daynumbers - day numbers frame 1-49 - day number buttons daynames - day names frame MON,TUE,WED,THU,FRI,SAT,SUN - day name buttons helpWindow - help window bcontrols - month buttons frame prev - previous month button succ - succeeding month button cdate - current date widget dayEditor - editor popup editorFrame - editor frame editorTitle - editor title editor - editor daybuttons - day buttons frame prevday - previous day button succday - succeeding day button editorControls- control panel doneButton - done button saveButton - save button clearEntry - clear entry button
Application specific resources:
reverseVideoMark - if True the entries are highlighted in reverse

Save button handler in the editor cannot detect when a text is pasted. Workaround : type something to the editor to activate save button.
