The calendar widget al- lows the user to traverse through months/years using the cursor keys. AVAILABLE FUNCTIONS activateCDKCalendar activates the calendar widget and lets the user interact with the wid- get. * The calendar widget is a pointer to a non-NULL calendar widget. * If the actions parameter is passed with a non-NULL value, the characters in the array will be injected into the widget. To activate the widget interactively pass in a NULL pointer for actions. If the character entered into this widget is RETURN then this function will return a type of time_t. * The time_t type is used in the functions defined in the time.h header file. (see localtime or ctime for more information). If the character entered into this widget was ESCAPE or TAB then this function will return a value of (time_t)-1 and the widget data exit- Type will be set to vESCAPE_HIT. destroyCDKCalendar removes the widget from the screen and frees memory the object used. drawCDKCalendar draws the label widget on the screen. If the box parameter is true, the widget is drawn with a box. eraseCDKCalendar removes the widget from the screen. This does NOT destroy the widget. getCDKCalendarBox returns whether the widget will be drawn with a box around it. getCDKCalendarDate returns the current date the calendar is displaying. getCDKCalendarDayAttribute returns the attribute of the day attribute of the calendar. getCDKCalendarHighlight returns the attribute of the highlight bar of the scrolling list por- tion of the widget. getCDKCalendarMarker returns the marker set on the calendar by setCDKCalendarMarker. getCDKCalendarMonthAttribute returns the attribute of the month attribute of the calendar. getCDKCalendarYearAttribute returns the attribute of the year attribute of the calendar. injectCDKCalendar injects a single character into the widget. * The parameter calendar is a pointer to a non-NULL calendar widget. * The parameter character is the character to inject into the wid- get. The return value and side-effect (setting the widget data exitType) depend upon the injected character: RETURN or TAB the function returns a value of type time_t (see localtime or ctime for more information). The widget data exitType is set to vNORMAL. ESCAPE the function returns (time_t)-1. The widget data exitType is set to vESCAPE_HIT. Otherwise unless modified by preprocessing, postprocessing or key bind- ings, the function returns (time_t)-1. The widget data exit- Type is set to vEARLY_EXIT. moveCDKCalendar moves the given widget to the given position. * The parameters xpos and ypos are the new position of the widget. The parameter xpos may be an integer or one of the pre-defined values TOP, BOTTOM, and CENTER. The parameter ypos may be an integer, or one of the pre-defined values LEFT, RIGHT, and CENTER. * The parameter relative states whether the xpos/ypos pair is a rel- ative move or an absolute move. For example, if xpos = 1 and ypos = 2 and relative = TRUE, then the widget would move one row down and two columns right. If the value of relative was FALSE, then the widget would move to the po- sition (1,2). Do not use the values TOP, BOTTOM, LEFT, RIGHT, or CENTER when relative = TRUE. (weird things may happen). * The final parameter refresh is a boolean value which states whether the widget will get refreshed after the move. newCDKCalendar creates a calendar widget and returns a pointer to it. Parameters: screen is the screen you wish this widget to be placed in. xpos controls the placement of the object along the horizontal axis. It may be an integer or one of the pre-defined values LEFT, RIGHT, and CENTER. ypos controls the placement of the object along the vertical axis. It may be an integer or one of the pre-defined values TOP, BOTTOM, and CENTER. title is the string which will be displayed at the top of the widget. The title can be more than one line; just provide a carriage re- turn character at the line break. year, month and day set the initial date of the calendar. yearAttrib, monthAttrib and dayAttrib represent the attributes of the year, month, and day respec- tively. highlight sets the highlight of the currently selected day. box is true if the widget should be drawn with a box around it. shadow turns the shadow on or off around this widget. If the widget could not be created then a NULL pointer is returned. positionCDKCalendar allows the user to move the widget around the screen via the cur- sor/keypad keys. See cdk_position (3) for key bindings. removeCDKCalendarMarker removes a marker from the calendar. setCDKCalendar lets the programmer modify certain elements of an existing calendar widget. * The calendar parameter represents an existing calendar pointer. * The other parameter names correspond to the same parameter names listed in the newCDKCalendar function. setCDKCalendarBackgroundAttrib sets the background attribute of the widget. The parameter attribute is a curses attribute, e.g., A_BOLD. setCDKCalendarBackgroundColor sets the background color of the widget. The parameter color is in the format of the Cdk format strings. See cdk_display (3). setCDKCalendarBox sets whether the widget will be drawn with a box around it. setCDKCalendarBoxAttribute sets the attribute of the box. setCDKCalendarDate sets the calendar to the given date. If the value of the day, month, or year parameters is -1 then the cur- rent day, month, or year is used to set the date. setCDKCalendarDayAttribute sets the attribute of the day in the calendar. setCDKCalendarDaysNames sets the names of the days of the week. The parameter is a string listing the 2-character abbreviations for the days. The default value is "Su Mo Tu We Th Fr Sa" "Su" (Sunday) is numbered zero internally, making it by default the first day of the week. Set the weekBase member of the widget to se- lect a different day. For example, Monday would be 1, Tuesday 2, etc. setCDKCalendarHighlight sets the attribute of the highlight bar of the scrolling list portion of the widget. setCDKCalendarHorizontalChar sets the horizontal drawing character for the box to the given charac- ter. setCDKCalendarLLChar sets the lower left hand corner of the widget's box to the given char- acter. setCDKCalendarLRChar sets the lower right hand corner of the widget's box to the given character. setCDKCalendarMarker allows the user to set a marker which will be displayed when the month is drawn. The marker parameter is the attribute to use when drawing the marker. If more than one marker is set on a single day, then the day will blink with the original marker attribute. setCDKCalendarMonthAttribute sets the attribute of the month in the calendar. setCDKCalendarMonthsNames sets the names of the months of the year. The parameter is a 13-element array (since indexing starts with 1). The default values are the English month names, e.g., "January". setCDKCalendarPostProcess allows the user to have the widget call a function after the key has been applied to the widget. * The parameter function is the callback function. * The parameter data points to data passed to the callback function. To learn more about post-processing see cdk_process(3). setCDKCalendarPreProcess allows the user to have the widget call a function after a key is hit and before the key is applied to the widget. * The parameter function is the callback function. * The parameter data points to data passed to the callback function. To learn more about pre-processing see cdk_process(3). setCDKCalendarULChar sets the upper left hand corner of the widget's box to the given char- acter. setCDKCalendarURChar sets the upper right hand corner of the widget's box to the given character. setCDKCalendarVerticalChar sets the vertical drawing character for the box to the given charac- ter. setCDKCalendarYearAttribute sets the attribute of the year in the calendar. KEY BINDINGS When the widget is activated there are several default key bindings which will help the user enter or manipulate the information quickly. The fol- lowing table outlines the keys and their actions for this widget. +-----------------+-----------------------------------------+ | Key | Action | +-----------------+-----------------------------------------+ +-----------------+-----------------------------------------+ | Left Arrow | Moves the cursor to the previous day. | +-----------------+-----------------------------------------+ | Right Arrow | Moves the cursor to the next day. | +-----------------+-----------------------------------------+ | Up Arrow | Moves the cursor to the next week. | +-----------------+-----------------------------------------+ | Down Arrow | Moves the cursor to the previous week. | +-----------------+-----------------------------------------+ | t | Sets the calendar to the current date. | +-----------------+-----------------------------------------+ | T | Sets the calendar to the current date. | +-----------------+-----------------------------------------+ | n | Advances the calendar one month ahead. | +-----------------+-----------------------------------------+ | N | Advances the calendar six months ahead. | +-----------------+-----------------------------------------+ | p | Advances the calendar one month back. | +-----------------+-----------------------------------------+ | P | Advances the calendar six months back. | +-----------------+-----------------------------------------+ | - | Advances the calendar one year ahead. | +-----------------+-----------------------------------------+ | + | Advances the calendar one year back. | +-----------------+-----------------------------------------+ | Return | Exits the widget and returns a value of | | | time_t which represents the day se- | | | lected at 1 second after midnight. | | | This also sets the widget data exitType | | | to vNORMAL. | +-----------------+-----------------------------------------+ | Tab | Exits the widget and returns a value of | | | time_t which represents the day se- | | | lected at 1 second after midnight. | | | This also sets the widget data exitType | | | to vNORMAL. | +-----------------+-----------------------------------------+ | Escape | Exits the widget and returns (time_)-1. | | | This also sets the widget data exitType | | | to vESCAPE_HIT. | +-----------------+-----------------------------------------+ | Ctrl-L | Refreshes the screen. | +-----------------+-----------------------------------------+ SEE ALSO cdk(3), cdk_binding(3), cdk_display(3), cdk_position(3), cdk_screen(3) 2025-01-14 cdk_calendar(3)
