labelField unfocus background color

I add a few labelField focusable on color management, when compiling with jre 4.7 or later version, it is ok, but with 4.5 labelFields background get white color when they are unfocuses.

From memory, there was a change made to LabelField approximately 4.6, so that he could extend over several lines, in which up to 4.5, you may lose this as well.  We could with the labelField autour mud so that it can work in both places, but I would swap that Exchange you using a RichTextField who is not active, since it provides little nearly the same features.

    Thank you

    The problem is in your calculation of width.

    Your should calculate your width in such a way that (approximate):

    Display.getWidth () = DateField width, width PED, Amt width + 2 * MyLine width;

    Furthermore, a solution may be simply change your constructor Amt class as below:

            Amt(String s)        {                   super(s,LabelField.RIGHT | Field.USE_ALL_WIDTH);        }

    How can set the background color of the status bar?
    Posted the: July 17, 2008 02:56
     
    How can set the background color of the status bar?
    Using this code for the status bar:
    LabelField statusField = new LabelField ("Good Morning", LabelField.USE_ALL_WIDTH |) LabelField.NON_FOCUSABLE | LabelField.HCENTER)
    {
    int _backgroundColour = Color.LIGHTGREEN;
    public void paint (Graphics g)
    {
    g.setBackgroundColor (Color.RED);
    g.Clear ();
    Super.Paint (g);
    }
    };

    Font defaultfont = Font.getDefault ();
    Police smallfont = defaultfont.derive (Font.PLAIN, 12);

    statusField.setFont (smallfont);
    setStatus (statusField);

    When I ran the code you have above, my status background color was red.  Is not what you see?  If so, please provide the BlackBerry model and software version that you are testing.  You can find this under Options.

    Or if you try to do something else, please provide details.

    I tested this in the BlackBerry Simulator included with version 4.5.0 BlackBerry JDE (4.5.0.44).

    To do this in version 4.1, first call getColor and save the current color.  Then call setColor, setting the color to the color you want to use for the background.  After this call call fillRect, starting with 0, 0 and go to the size of the field (use this.getWidth () and this.getHeight () to get this).  This must fill in the field with your specified color.

    To allow the drawing of the default content of the field call setColor once again, passing in the original color, then call super.paint.

  • How to set the background color of the title?

    Generally, the title background color is black and the other area of the main screen is white. I want to set the background color of the linear gradient background as blue or something. I try the following 2 ways, but there is always a black line at the bottom of the title bar.

          Background background = BackgroundFactory
                .createLinearGradientBackground(0x00ff0000, 0x00ff0000,
                        0x0000ff00, 0x0000ff00);
        LabelField title = new LabelField("Hello World Demo",
                LabelField.ELLIPSIS | LabelField.USE_ALL_WIDTH);
        title.setBackground(background);
        setTitle(title);

           LabelField title = new LabelField("Hello World Demo",
                LabelField.ELLIPSIS | LabelField.USE_ALL_WIDTH);

        HorizontalFieldManager hrzManager = new HorizontalFieldManager() {
            protected void paintBackground(Graphics graphics) {

                graphics.setBackgroundColor(0x00382B79);
                graphics.clear();
                super.paint(graphics);
            }
        };
        hrzManager.add(title);
        setTitle(hrzManager);

    Hello

    I think that there may be a problem using the default setTilte() method.

    Have something by default, behavior with the device.

    It may be a way to customize the default title to remove the black line at the bottom of the title bar.

    But I suggest an alternative that will behave like the title bar without using the setTitle() method.

    You can use something like below to get your condition.

}
.slider *.track {

        -fx-padding: 10;
}

    I don't know why I can't get the node of the track, track has always set to null and the thumb or the other.

    After that the cursor was displayed on an active scene are you doing research?

    (ex.: after you have added the slider to a scene, the scene for scene, then called stage.show ())

  • Change background color of page newtab to black.

    I can't change the background color of my page newtab to something other than white that it is today. Navigation in a dark room is extremely blinding, when opening the newtab page. In the past, I modified my file userContent.css with the following (among others):

    @-moz - document url("about:newtab")
    {

    #newtab-scrollbox{background-color:#000000!important;}
#newtab-window{background-color:#000000!important;}

    }

    He has always worked and got the results I want, but given that I have updated to Firefox 42.0 this morning it doesn't seem to work. My background color of the newtab is white broken and is much too bright for my taste.

    I have a strong preference NOT to install additional modules to do this, as it should be easy to do from the userContent.css file. Don't know why my code doesn't work anymore...

    If I take the following in userContent.css, * {background-color: #000000;}, she to obvious effect to all black, including the newtab cell background. This tells me I can put a background, I just need the proper syntax.

    I just upgraded to Firefox 42.0 and, unlike previous versions, the setting of background color in 'Content' no longer works. In the settings page, the indicator 'Background colour' changes the color I choose (not white) in the choice of color theme, but each time I open an empty window background color is always white. Then, when I return to the Setup page to verify that the indicator still shows the color that I chose.
