Hi,

I think you can use getPreferredHeight() and getPreferredWidth() methods of TextField() to resize you TextField.

I have used these methods for my ButtonField.

Here is the code.I think this should work for TextField also

  add(new ButtonField("Set Reminder",ButtonField.FIELD_HCENTER | ButtonField.FIELD_VCENTER){ 
                public int getPreferredWidth(){
                    return 130;
                }
                 
                public int getPreferreHeight(){
                    return 30;
                }  
        
            });

Instead of hardcoding your values you can write your logic.

Please let me know did it solved your problem or not.

Please igone this post this was  by mistake

Hi,

I think you can use getPreferredWidth() and getPreferredHeight() methods of TextField to change size of your Field.

I have done this for my ButtonField hope it can help you out also.

Code for this is below.

      add(new ButtonField("Set Reminder",ButtonField.FIELD_HCENTER | ButtonField.FIELD_VCENTER){

                 public int getPreferredWidth(){
                    return 130;
                 }
                
                 public int getPreferreHeight(){
                    return 30;
                 }  
     });

Instead of returning hard coded values return values accordingly.

Please let me know this solved your problem or not.

Hi again, thenks to all of you for the replyes. I finally fixed it . Following some hints here and after doing some reading on Layout managers I learned that scrolling is handled by the manager so I did the folowing: I set the screen manager to NO_VERTICAL_SCROLL and add the ListField in a scrollable Vertical manager. After that I added a focusable TextField to the screen and everything works like a charm. Here is the result in short, maybe someone else will bump into this problem:

super(MainScreen.FOCUSABLE | MainScreen.NO_VERTICAL_SCROLL);
.......
VerticalFieldManager l_manager = new VerticalFieldManager(Manager.VERTICAL_SCROLL | Manager.VERTICAL_SCROLLBAR);
add(l_manager);
l_manager.add(_itemList);
add(new TextField(TextField.FOCUSABLE | TextField.READONLY));

Edited to change NullField with TextField....aparently NullField didn't work after restarting the simulator...

thanks danyw it works,  it was just enough for me to use :

super(MainScreen.FOCUSABLE | MainScreen.NO_VERTICAL_SCROLL);

and

add(new TextField(TextField.FOCUSABLE | TextField.READONLY));

but in order to prevent a problem when last row is selected and user press the down arrow key, i also used:

    protected boolean navigationMovement( int dx, int dy, int status, int time ){

        invalidate();
        if (listSettings.getSelectedIndex() == LASTINDEX && dy > 0)
        	return true;
...

well, TextField constructor is not available in os 4.2.1.

Any alternative?

edit:

ok, BasicEditField works as well. but it get selected by scrolling to it in non touch devices.

I guess i will put an if condition to see if it's a touch device.

Use this code :

public boolean navigationClick(int status, int time) {

       Field focus = UiApplication.getUiApplication().getActiveScreen() .getLeafFieldWithFocus();
            
            if (focus instanceof ListField) {
                int selected = menu.getSelectedIndex();
                switch (selected) {

                         case 0 :

                          case 1:

                }

       }

}
