to prevent the selection of the first row by default , i finally used this hack:
...
int firsttime = 0; // member
public void drawListRow(ListField list, Graphics g, int index, int y, int w) // draw row
{
int height = g.getFont().getHeight();
int width = Display.getWidth();
int selectedItem = list.getSelectedIndex();
// hack to prevent the selection on the first row
if (index == 0 && firstTime < 2)
{
selectedItem = - 1;
firstTime ++;
}
if(selectedItem == index)
{
g.clear();
g.setColor(Color.BLUE);
g.fillRect(0,y,Display.getWidth(),height*300/100);
g.setColor(Color.WHITE);
}
else
{
g.setColor(Color.LIGHTGREY);
g.fillRect(0,y,Display.getWidth(),height*300/100);
g.setColor(Color.BLACK);
}
...
it happens that 2 times upon loading the listfield the function enters with selectedItem equal to 0 , so this bypasses those two times.
I also used the overridings realcaracas posted in the previous page to prevent multiple selections when a key is down.
i had to do one more hack there to select first row when the down arrow is pressed, and to prevent user from going to the next field when last row is selected and he press the down arrow key:
protected boolean navigationMovement( int dx, int dy, int status, int time ){
invalidate();
if (listSettings.getSelectedIndex() == 2 && dy > 0)
return true;
else if (firstTime == 2 && listSettings.getSelectedIndex() == 0 && dy > 0)
{
firstTime ++;
listSettings.setSelectedIndex(0);
return true;
}
return super.navigationMovement( dx, dy, status, time );
}
