複数行のテキストボックス、ブラックベリーのボーダー付き

Question

私はブラックベリーが初めてです。これは私の最初の質問です。私はこれに対して複数のtextbox.iが必要なサンプルアプリケーションを作成しています。

VerticalFieldManager vfm =new VerticalFieldManager(Manager.VERTICAL_SCROLL) 
      { 
       public void paint(Graphics g) 
          { 

          g.drawRoundRect(0, 0,getWidth(), getHeight(),12,12); 
         super.paint(g); 
        } 
       public void sublayout(int width, int height) 
           { 
         if (managerWidth == 0) { 
         managerWidth = width; 
         } 
         if (managerHeight == 0) { 
         managerHeight = height; 
         } 
         super.sublayout(managerWidth, managerHeight); 
         setExtent(managerWidth,managerHeight); 
        } 

      }; 

       editField = new EditField(){ 
       public void paint(Graphics g) { 
       getManager().invalidate(); 
       super.paint(g); 
       } 
      }; 

      vfm.add(editField); 
           vfm.setBackground(BackgroundFactory.createSolidBackground(Color.WHITE)); 
      add(vfm); 

テキストフィールドheight.Theのテキストは、私がproblem.Pleaseが私を助けることを修正border.Howを横切っているよりも大きい場合、テキストは、フィールドの高さよりも小さい場合には、正常に動作します。

Answer 1

独自のカスタムフィールドを実装する必要があります。

マニュアルは、ここで見つけることができます："Create a custom field"

Answer 2

あなたはブラックベリーのAPIおよび使用からEditFieldを使用することができます。

yourEditField.setBorder(yourBorder); 

あなたはその後、国境での編集フィールドを持っていると

Answer 3

数行を受け入れるだろう
