ここでは、「Wicket PropertyModel で、WebPage とデータを分離する」に、日付の入力補助をする DatePicker? を付け加えてみる。

pom.xml の修正
HomePage.javaの改修
こんな感じになる
DatePickerって、wicket-extension に入っていなかったっけ？
日付の書式

pom.xml の修正 †

DatePicker?を使うためには、wicket-datetime コンポーネントが必要なので、POMに足すことにする。
ついでに、wicket-extension も追加する
ついでに、wicketのバージョンを 1.3.0-rc2 から 1.3.0 にする

と言うことで、pom.xml はこんな感じになった

HomePage.javaの改修 †

日付の入力欄を TextField? から DateTextField? に変更
- DateTextFiled?は、日付検証がなされる TextField?。以下の二つは、ほぼ等価
  - TextField? txtDate = new TextField?("date", new PropertyModel?(diary, DiaryVO.DATE) ,Date.class);
  - DateTextField? txtDate = new DateTextField?("date", new PropertyModel?(diary, DiaryVO.DATE));
- wicket-extension に含まれる
TextField? に、DatePicker? を add する
- wicket-datetime に含まれる

まぁこんなかんじ

package com.snail;

import org.apache.wicket.PageParameters;
import org.apache.wicket.extensions.markup.html.form.DateTextField;
import org.apache.wicket.extensions.yui.calendar.DatePicker;
import org.apache.wicket.markup.html.WebPage;
import org.apache.wicket.markup.html.form.DropDownChoice;
import org.apache.wicket.markup.html.form.Form;
import org.apache.wicket.markup.html.form.TextArea;
import org.apache.wicket.markup.html.form.TextField;
import org.apache.wicket.markup.html.panel.FeedbackPanel;
import org.apache.wicket.model.PropertyModel;

/**
 * Home page.
 */
public class HomePage extends WebPage {

	private static final long serialVersionUID = 3598788934381254916L;

	private Form form = new Form("f") {
		private static final long serialVersionUID = -1700095884500348972L;

		@Override
    protected void onSubmit() {
      ResultPage result = new ResultPage(diary);
      setResponsePage(result);
    }
  };

  private DiaryVO diary;

  private FeedbackPanel feedback = new FeedbackPanel("msg");

  public HomePage(final PageParameters parameters) {
    this(new DiaryVO());
  }

  public HomePage(final DiaryVO pDiary) {
    this.diary = pDiary;

    add(feedback);

    add(form);

    TextField txtSubject = new TextField("subject", 
        new PropertyModel(diary, DiaryVO.SUBJECT));
    txtSubject.setRequired(true);
    form.add(txtSubject);

    DropDownChoice cmbType = new DropDownChoice("type",
        new PropertyModel(diary, DiaryVO.TYPE), diary.getTypeList());
    cmbType.setRequired(true);
    form.add(cmbType);

    // !!! CHANGED BELOW !!!
    DateTextField txtDate = new DateTextField("date",
        new PropertyModel(diary, DiaryVO.DATE));
    txtDate.setRequired(true);
    txtDate.add(new DatePicker());
    form.add(txtDate);
    // !!! CHANGED ABOVE !!!
    
    TextArea txtArticle = new TextArea("article", new PropertyModel(diary,
        DiaryVO.ARTICLE));
    txtArticle.setRequired(true);
    form.add(txtArticle);
  }
}

こんな感じになる †

すばらしい！！！

DatePicker?って、wicket-extension に入っていなかったっけ？ †

Wicket1.3になるときに分割されたらしい

http://cwiki.apache.org/WICKET/migrate-13.html#Migrate-1.3-DatePicker

The DatePicker component has been removed from the wicket-extensions package,
as it conflicts with the Apache license.

There are two options for migration:

   * A drop-in replacement (same component) provided by Wicket Stuff.
   * A new date picker based on the Yahoo UI library,
     which is available in the wicket-datetime package.
     Find it under wicket.extensions.yui.calendar.DateField
     (see also DateTimeField and CalendarPopup for other useful components).

と言うことらしい

日付の書式 †

DateTextField? で、書式を指定する

DateTextField txtDate = new DateTextField("date",
  new PropertyModel(diary, DiaryVO.DATE),"yyyy年MM月dd日");

書式は java.lang.SimpleDateFormatの書式
日付の書式を指定すると、IEコンポーネント( Eclipse )で、ときどきヘッダ(年月）が出てこないことがある。
- 書式を指定しないと IEコンポーネント( Eclipse )でも巧く動く
- Firefox2 / IE7 では、書式の指定をしても特に問題なく動くので、まぁいいや
- まるまる土日をかけて調べてみたけど何が原因か分からない・・・orz*1
