WebObjects/Web Applications/Development/Examples/Calendar Component

Here is a little example on how to write a "calendar" component:

So you have a specific month, some of the dates are links (that will depend on what the calendar is for) and some basics navigations (next/previous month, year).

That's how the html could look like:

  <webobject name = "Table">
    <tr>
      <td align = "left" valign = "top" colspan = "7">
        <webobject name = "Month"></webobject>
        <webobject name = "HasNavigation">
           <webobject name = "YearLink"><webobject name = "Year"></webobject></webobject>
        </webobject>
      </td>
    </tr>
    <webobject name = "Rows">
      <tr>
        <webobject name = "Columns">
          <td align = "right" valign = "top">
            <webobject name = "HasLink">
              <webobject name = "IsCurrentDay"></webobject><webobject name = "Link"><webobject name = "Day"></webobject></webobject><webobject name = "IsCurrentDay"></webobject> 
            </webobject>
            <webobject name = "HasNoLink">
              <webobject name = "Day"></webobject> 
            </webobject>
          </td>
        </webobject>
      </tr>
    </webobject>
    <webobject name = "HasNavigation">
      <tr>
        <td align = "left" valign = "top" colspan ="3">
          <webobject name = "HasPreviousMonth">
            <small><webobject name = "PreviousMonthLink"><webobject name = "PreviousMonth"></webobject></webobject></small>
          </webobject>
        </td>
        <td align = "left" valign = "top">
           
        </td>
        <td align = "right" valign = "top" colspan ="3">
          <webobject name = "HasNextMonth">
            <small><webobject name = "NextMonthLink"><webobject name = "NextMonth"></webobject></webobject></small>
          </webobject>
        </td>
      </tr>
    </webobject>
  </webobject>

And here is the wod:

 Table: WOGenericContainer{
   elementName = "table";
   border = "0";
   cellSpacing = "0";
   cellPadding = "0";
 };
 HasNavigation: WOConditional
 {
   condition = hasNavigation;
 };
 
 YearLink: WOHyperlink{
   action = displayYear;
 };
 Year: SpanString{
   value = month.year;
   isBold = true;
   isSmall = true;
   class = "Label";
 };
 Rows: WORepetition{
   count = rowCount;
   index = rowIndex;
 };
 Columns: WORepetition{
   count = columnCount;
   index = columnIndex;
 };
 Month: SpanString{
   value = month.monthName.toUpperCase;
   isBold = true;
   isSmall = true;
   class = "Label";
 };
 DayName: SpanString{
   value = dayName;
   isSmall = true;
   class = "Label";
 };
 HasLink: WOConditional{
   condition = hasLink;
 };
 HasNoLink: WOConditional{
   condition = hasLink;
   negate = true;
 };
 IsCurrentDay: WOConditional{
   condition = isCurrentDay;
 };
 Link: WOHyperlink{
   action = displayDay;
 };
 Day: SpanString{
   value = day.day;
   isSmall = true;
   isBold = isCurrentDay;
   isItalic = isCurrentDay;
   class = "Label";
 };
 HasNextMonth: WOConditional{
   condition = hasNextMonth;
 };
 NextMonthLink: WOHyperlink{
   action = displayNextMonth;
 };
 NextMonth: SpanString
 {
   value = nextMonthName;
   isSmall = true;
   class = "Label";
 };
 HasPreviousMonth: WOConditional{
   condition = hasPreviousMonth;
 };
 PreviousMonthLink: WOHyperlink{
   action = displayPreviousMonth;
 };
 PreviousMonth: SpanString{
   value = previousMonthName;
   isSmall = true;
   class = "Label";
 };

The component implementation is left to the imagination
