    Is there a way to add a new preview resolution to the LWUITDesigner?

    There is 640x320 but the new Nokia phones are 640x360. How can I add this resolution to the preview options?

    Hi,

    iam trying to apply a theme to my application but i get some error,

    this is the error:

    java.lang.NullPointerException
    at
    java.io.DataInputStream.read
    java.io.DataInputStream.readUnsignedShort(+4)
    java.io.DataInputStream.readShort(+4)
    com.sun.lwuit.util.Resources.openFile
    com.sun.lwuit.util.Resources.init
    com.sun.lwuit.util.Resources.open
    login.loginscreen.startApp

    java.io.IOException
    at com.sun.lwuit.util.Resources.open
    login.loginscreen.startApp

    I wrote it in the function startApp like this:

    Resources res = Resources.open("src/myTheme.res")

    All the build process do it well in fact, the application runs but, it doesnt load the Theme.

    Please help me to figure out whats going on.

    Thanx.

    May be because of wrong path

    Resources res = Resources.open("src/myTheme.res")

    Try this

    Resources res = Resources.open("/src/myTheme.res")

    Is it possible to copy and paste a theme inside a Resource file by using the ResourceEdit tool?

    I just need to have a second resource file with minor changes and I don't want to add everything from the scracth..

    I hope somebody will see this as it's been quite a while that someone has posted here..

    Thanx :)

    @Micha: use an action listener.

    @Taxiarchis: It is not possible to copy a theme but we have something better. You can load a theme using setThemeProps() then use addThemeProps() to add properties or perform minor tweaks to the theme.

    The new resource editor has a new file format which won't work with older versions of LWUIT.
    Newer versions of LWUIT only read the new file format (we dropped backwards compatibility to the really old format).

    LWUIT Designer is getting stuck when I open a Theme. I open editor.jar fine. I open my RES file fine. I pick the MIDlet fine. I select the Theme (which I created several weeks ago and haven't touched since) and it all freezes. This also happened to me at first with the LWUIT Demo and its theme, but picking the MIDlet seemed to have solved the problem there.
    I went back to my app and selected the LWUIT Demo as the MIDlet with my RES file and it opened. So what's wrong with my MIDlet? Thanks :-)

    LWUIT Designer does not seem to preview the Gradient X/Y parameters - using LWUIT demo, playing with the Gradient colors is immediately visible in the demo midlet on the side. But playing with the X/Y params - nothing seems to change. What am I missing?

    There seems to be a bug in JavaSE's ImageIO API that causes some images to trigger a security exception (not your fault). I worked around that bug in the current SVN and pick MIDlet should now work fine (make sure to update the link to the new resource editor link mentioned in my latest posts).
    The positioning of the radial gradient seems to be always the center right now. This is probably a regression I did a couple of weeks ago. I'll try and fix it.
