Scrolling AND selecting items in a ListField on the storm?

Background information:

BlackBerry Storm 9500

BlackBerry JDE 4.7.0

Problem:

I use a ListField to display several items in a list. I also use the touchEvent (TouchEvent message) method to listen to a click (TouchEvent.CLICK). Well, everything seems to work except when I need to scroll through the list. It seems that using the touchEvent method, I can't scroll through the list. If I remove the touchEvent method, scrolling works but I am unable to use the touch interface to select an item in the list by clicking on it.

Question:

Is it possible to get both? In other words, can enable scrolling in the ListField AND allow the user to select an item by clicking on it?

Code:

private class SlideList extends screen

{

Fields

private ListField _list;

Private _callback ListCallback;

Constructor

public SlideList()

{

Super();

Add a title screen

LabelField title = new LabelField (getTitle (), LabelField.ELLIPSIS |) LabelField.USE_ALL_WIDTH);

setTitle (title);

setupList();

}

Private Sub setupList()

{

If (_list! = null)

Delete (_list);

Get all the slides and put their titles and subtitles in a table

String [] slideTitles = getSlideTitles();

_list = new ListField();

_callback = new ListCallback();

_list.setCallback (_callback);

Build the list of exercise.

for (int index = 0; index)

{

_list. Insert (index);

_callback. Insert (slideTitles [index], index);

}

_list.setSelectedIndex (currentSlideNum);

Add (_list);

}

Get the touch input.

protected boolean touchEvent (TouchEvent message)

{

If (message.getEvent () is TouchEvent.CLICK)

{

Check if a list item is selected.

If (_list.getSelectedIndex () > - 1).

{

Dialog.Alert ("you selected:" + _list.getSelectedIndex ());

itemSelected (_list.getSelectedIndex ());

Returns true;

}

on the other

Returns false;

}

on the other

Returns false;

}

Private Sub itemSelected (int listIndex)

{

currentSlideNum = listIndex;

displaySlide();

UiApplication.getUiApplication () .popScreen (this); Remove this screen to display the program.

}

private class ListCallback implements {ListFieldCallback}

private vector listElements = new Vector();

' public void drawListRow (list ListField, Graphics g, int index, int y, int w)

{

String text = (String) listElements.elementAt (index);

g.drawText (text, slideIcons [index] .getWidth () + 10, y, 0, w);

}

public Object get (ListField list, int index) {}

Return listElements.elementAt (index);

}

public int indexOfList (String p, ListField list, int s) {}

Return listElements.getSelectedIndex ();

Return listElements.indexOf (p, s);

}

public int getPreferredWidth (ListField list) {}

Display sr = UiApplication.getUiApplication () .getActiveScreen ();

Return sr.getWidth ();

}

public final void insert (String toInsert, int index) {}

listElements.insertElementAt (toInsert, index);

}

{} public void erase()

listElements.removeAllElements ();

}

Mark,

Thanks for your reply. It turns out that the solution I was looking for was very simple. Rather than return

fake

in the touchEvent method, I back

super.touchEvent (message)

While touchEvent can call its parent class and always look for other events inherent in a listenField, such as scrolling with a finger.

It now looks like this:
