Hi List.

I have a simple shell with two push button. When i try to run my app
inside PDA i can´t see the button with image inside. On PC all works ok.
Here is a segment of my code.

/**
* This method initializes sShell
*/
private void createShell() {
mainShell = new Shell(SWT.APPLICATION_MODAL | SWT.DIALOG_TRIM);
ImageLoader imagesResources = ImageLoader.getInstance();
clienteButton = new Button(mainShell, SWT.NONE);
articuloButton = new Button(mainShell, SWT.NONE);

clienteButton.setImage(imagesResources.stockImages[imagesRes ources.cmdCliente]);
articuloButton.setImage(imagesResources.stockImages[imagesRe sources.cmdArticulo]);


}

Thanks Danny

You can't use images inside buttons in the PocketPC. You need to use a label
instead. I'm working on the same kind of thing at the moment. You need to
register an event on the label for the click.

On the subject, if anyone has a nice code snippet of a Label with an image,
used as a button, on the pocket pc I'd like to see it. Can we have a nice
effect for the button pressed state too please :-)

yes, i think you are right, if toolbar suits you. You'd have to customise
the toolbar in some way i'd expect depending on your application, but I'm
not the person to ask as I haven't tried that solution either. I think it
would be nice to see some examples anyway, so I'll post my solution and you
can post one too if you like.

Hi Andy and Danny,

to use a toolbar do not solve the problem, too. On PocketPC there are no
buttons with an image!

I wrote a new widget to solve the problem. Use the attached class.

Bye Stefan

Can i put your imageButton in flat style?.

Thanks again

Thanks for the ImageButton class Stefan, just the ticket.

I've looked at both ToolBar and Stefan's ImageButton and I think that they
both have their merits. It will good to use ImageButton next to normal text
buttons on the pocket pc I'm thinking, it seems to give the same look and
feel. It's good to use the ToolBar for err... toolbars!

I'm not sure what you mean Danny about the toolbar button exceeding the
height of the toolbar. Can you make a small example?

Andy

Hi Danny,

I did not implement flat style yet, because I do not need it. But feel free
to change my code for your requirements.

I don't no which problems I have had with toolbars, but I think there were
some.

Hi Stefan. I have a problem using your ImageButton.java class. Maybe you
can help me. It´s a piece of my code.

ImageButton buttonBuscar = new ImageButton(cargaShell,SWT.NONE);

buttonBuscar.setLocation(25,2);
buttonBuscar.setSize(24,24);
buttonBuscar.setImage(imagesResources.stockImages[imagesReso urces.cmdBuscar]);

buttonBuscar.addSelectionListener(new SelectionListener(){

public void widgetSelected(SelectionEvent arg0) {
// TODO Auto-generated method stub
ArenaMobileBuscaCarga buscaCargaUI = new ArenaMobileBuscaCarga(new
Carga(ArenaMobileResources.dataSource));
Rectangle shellRect = buscaCargaUI.getShell().getBounds();
Rectangle displayRect = cargaShell.getDisplay().getBounds();
int x = (displayRect.width - shellRect.width) / 2;
int y = (displayRect.height - shellRect.height) / 2;
buscaCargaUI.getShell().setLocation(x, y);
buscaCargaUI.getShell().open();

while( !buscaCargaUI.getShell().isDisposed())
{
if(!Display.getDefault().readAndDispatch())
Display.getDefault().sleep();
}

I´m getting this error.

java.lang.NullPointerException

Hi Danny,

I have no idea at the moment. I don't see any dependencies of the codes.
ImageButton notifies all Listeners, but you didn't use any variable of
ImageButton in widgetSelected.

I think you have to debug your method widgetSelected.

Bye Stefan
