Hi Hezi,
I didn't quite understand what are you asking, can you share more info?
Are you trying to create some sort of a File browser?
Thanks,
Chen

Hi Chen
My qustion is very basic.
I build a menu wtih LWUIT:
public void startApp() {
Display.init(this);
final Form f = new Form("Hello, LWUIT!");
Label label = new Label("Baldy");
f.addComponent(label);
try {
Image image = Image.createImage("/res/duke.png");
Image image1 = Image.createImage("/res/Animations_sel.png");
Label pictureLabel = new Label(image);
f.addComponent(pictureLabel);
Label pictureLabel1 = new Label(image1);
f.addComponent(pictureLabel1);
.
.
.
This work ok.
Now, I want to select btween image1 and image (something like:
void handleActions(int keyCode) {
int action = getGameAction(keyCode);
switch (action) {
case LEFT:
x -= 1;
break;
case RIGHT:
x += 1;
break;
case UP:
y -= 1;
break;
case DOWN:
y += 1;
break;
}
}
)
but in a LWUIT way - means: to write the code in actionPerformed(ActionEvent ae)
second, I want the selected image to ZOOM IN or to change color so i can see the choosem image.
How can I do it?
TIA
Hezi

Hi Hezi,
Labels by default doesn't grab focus, to enable focus on Labels you need to call:
Label.setFocusable(true);
Regarding the second part of your question about events:
If you want to preform some action when the user clicks on the images, you might want to us a Button instead of a Label.
You can Choose to draw the button without borders if you prefer the "Label look" by calling to Button.setBorderPainted(false), then add your action on the button by using
Button.addActionListener(ActionListener l), the listener code will be invoked when the user clicks on the FIRE key.
Regards,
Chen
