Trying to create a calendar - need some guidance
Hi all.
I'm trying to build a component-ized calendar that will be the centerpiece
of a new application I'm working on. I built one this morning in JSP and
was able to do it with very little code. I kept it simple and I'm hoping I
can retro-fit the logic into a wicket page cleanly, without too much
trouble. I'm a little stuck because in my JSP, I simply loop through the
days and print until Saturday is reached, then I break to a new table row
and continue. Doing this in Wicket seems tough because if I use a ListView,
I can't be as flexible as far as throwing in a new row while looping and
outputting table cells.
Here's the rough idea I came up with today in JSP, can someone give me some
pointers?
<%@ page contentType="text/html" pageEncoding="UTF-8" %>
<%@ page import="java.util.*" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<%
//get parameters to change date
String monthParam = request.getParameter("month");
String yearParam = request.getParameter("year");
//create calendar object
Calendar cal = Calendar.getInstance();
cal.setFirstDayOfWeek(Calendar.SUNDAY); //set first day to Sunday
if (monthParam != null)
cal.set(Calendar.MONTH, (Integer.valueOf(monthParam)-1));
if (yearParam != null)
cal.set(Calendar.YEAR, Integer.valueOf(yearParam));
//get total number of days in month
int numDaysInMonth = cal.getActualMaximum(Calendar.DAY_OF_MONTH);
//get current month name in English
String monthName = cal.getDisplayName(Calendar.MONTH, Calendar.LONG,
Locale.ENGLISH);
//get current year
int year = cal.get(Calendar.YEAR);
//get array of day names
String[] headers = {"Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"};
%>

<tr>
<!-- loop and print days -->
<%
for (int i=0; i<7; i++)
{
%>
<td><%= headers[i] %></td>
<%
}
%>
</tr>
<!-- DRAW CALENDAR -->
<tr>
<%
for (int i=1; i<=numDaysInMonth; i++)
{
//re-set calendar day in context of loop
cal.set(Calendar.DAY_OF_MONTH, i);
//get the day number of the week
int day = cal.get(Calendar.DAY_OF_WEEK);
//days without numbers count
int blankDays = 0;
//blank days before 1st of month?
if (i == 1 && day > 1)
{
blankDays = day - i; //get count
//loop through count and print blank day
for (int x=1; x<=blankDays; x++)

I'd really appreciate that Edgar, thanks!
As for the GridView - "duh" for me.
On another note, I just finished another one of our corporate sites, using
Wicket. Check it out, let me know your thoughts, criticisms, etc. I used
Wicket because I built our storefront a couple years ago with Wicket as well
and eventually they'll be more tightly integrated.
Everything is Wicket + Java EE 5 on Glassfish V2.

Re: Trying to create a calendar - need some guidance
Posted by Edgar Merino <do...@gmail.com>.
I've got an abstract calendar already coded, the only problem is that
it's using a DataTable (instead of only a gridview), I have to change
the code to use the gridview instead, I'll post the code tomorrow if
I've got the time and you're still interested.

Yes, of course, but because webical is opensource, you can study the sources
and see they are building their calendar.

Thanks, but it's important that I build my own, given the nature of this
project. It took me 1.5 hrs. to do what I did in JSP so it's not like I'm
trying to accomplish a huge task.

Re: Trying to create a calendar - need some guidance
Posted by John Krasnay <jo...@krasnay.ca>.
ListView is good if you already have a list of things you want to
display. For this kind of iteration you'd be better off with a
RepeatingView. Here's how I might tackle it:
- create a top-level panel to hold the calendar. The markup would
contain your table element, and would have a RepeatingView attached
to a tr element
- create a panel representing the row, which has a RepeatingView
attached to a td element.
- create a panel representing a day.
- put your loop in the ctor of the top-level panel. Start by creating a
row panel and adding it to the first RepeatingView. Then for each day,
create a day panel and add it to the repeating view in the row. When
you get to the Saturday, just create a new row panel as the "current"
one, add it to the first RepeatingView, and continue on your way.
Now for the cool part: you could put the part where you create the day
panel into an overrideable method. Then you could re-use the component to
generate all kinds of different calendars by simply subclassing and
returning different kinds of day panels.

Igor, thanks again for the clue on using GridView, I got it figured out and
it works great! I attached the code in case anyone's interested in drawing
a basic calendar. It's lean and clean so it's easy to extend.
