JPanel - how to introsuce shades in the background color ?

Hi Guys,
I want to creat a JPanel with a background color, which is actually shades of gray color. Thus the left part of the JPanel will be dark gray, and from thereon the intensity of the gray color will be decreased more and more till be reach the right end of the JPanel where it will be really light gray.
This is exactly the same color effect which you all can see behind the "Sun Developer Network" written at the top of all these forums.
Can anyone help me please.
Thanks,
S

Use a GradientPaint for the background. Here is an example for a text field to get you started:

    Hi Kyn,
    Perhaps you (or anyone else!) can help me with this too: is it possible to change the color of the border styles that you choose for the thumbnails on a photo page? There is no "fill" option in the Graphic pane of the inspector when I select one of them. I love some of the styles but would like to be able to match the color better to my pages. See here for an example:

    The twirly border is a little too orange for my taste.
    Thanks in advance.

  • How do I apply a specific background color in InDesign?

    The background color is identified in Ps as "edf7e4", and it is a very pale green.  How do I make this the background color for my book cover in InDesign?

    You must add a frame to your cover page(s) at the bottom of the stack and fill it with the color that you wish to use (you can keep the RGB definiton and convert on export, too, if you need CMYK for press). Don't forget to bleed the edges where required.

  • How can I reset the background color of a JPanel to it's default value?

    I have some JPanels that I set their background color to white when I add some objects in them. After some operations the objects are removed and I'd like to reset the background color back to it's default gray. Any suggestions on how to do this? Thanks.

    I took a guess and I figured it out. Just set the background color to null.
    JPanel panel = new JPanel();
    panel.setBackground(Color.white);       //Set Panel to White
    Operations......
    panel.setBackground(null);                 //Reset Panel Color to Default Gray

  • How to change the background color of a sequence?

    I'm using Premiere Pro CS5 on Win7 x64.  I've imported a JPEG that's a different size than my 1920 x 1080 frame.  The background of this JPEG is white, but the background of the sequence is black (by default), so the borders of the JPEG make it stand out.  I want the JPEG to blend into the sequence background by making the sequence background white.  How can I change the sequence background color?  Thanks.

    Jim and Ann are correct. I can see where someone used to After Effects might ask that question though because in AE you can change the background color of the composition. Same with Photoshop.
    However, I think it would confuse things if changing the background color were to be allowed in Premiere Pro. Black tells me something. I suppose white could tell me the same thing, but at this time it is not possible in Premiere Pro.

  • How to change the background color of  a Tab Canvas

    Hi All,
    I accidentally changed existing background color of a tab Canvas to ' gray' which is not matching with main canvas (which has default).
    How can I change background color to default. Please help me.
    -Thanks

    In the property palette of the tab page, click on the "Background Color" property and click the "Inherit" button on the top of the property palette, this will revert the value of the property to the default when the tab page was created which is <Unspecified>.
    But if your tab page has inherited the color from a property class it will revert to what was specified in the property class.

    Themes work in Thunderbird - duggabe was not refering to Firefox.
    Another useful addon is theme and font changer:
    * https://addons.mozilla.org/fr/thunderbird/addon/theme-font-size-changer/
    However, Thunderbird allows you to modify all sorts of things.
    Make hidden files and folders visible:
    * http://kb.mozillazine.org/Show_hidden_files_and_folders
    Help > Troubleshooting Information
    Click on 'show Folder' button
    a window opens shwoing profile folder name
    Close Thunderbird now - this is important
    In the profile name folder, Create a new folder called '''chrome''' - note the spelling
    It should be in the same place as the 'Mail' folder.
    see first image below.
    Open Notepad
    Can be located : Start > Programs > accessories
    Copy everything shown between the lines below.
    Paste into Notepad.
    Save as '''userChrome.css''' - note the spelling (edit updated - this was a typo error)
    This should be saved in the '''chrome''' folder.
    see second image below.
    Restart Thunderbird.
    I have chosen a yellow for you
    <pre>
    #f6f58c = a yellow....it is a hex code for a colour.
    </pre>
    You can change it if required. Remember when updating anything in the profile folders, you must close Thunderbird first.

  • How to change the background color of a cell in datagrid using flex3

    i want to change the background color of a cell.....how can i achieve this.....and also i want to know how a spacing cane be done between cells in a datagrid...plzzz help me???

    The only way I can see to do this is to use an item renderer for your cells.  This is really scruffy and would need tyding up, and maybe with a little more time could do better or someone else may have an idea but none the less this works.
    Define a custom component as below;
    This has logic to see what the value of the data is proveided by the dataprovider for the row, and if it matches the conditions in this case is equal to 5 sets the background color.
    <?xml version="1.0" encoding="utf-8"?>
    <mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" width="88" height="26" dataChange="doColor()" borderColor="#000000" borderStyle="solid"
        backgroundAlpha="1">
        <mx:Script>
            <![CDATA[
                private function doColor():void {
                    if (data.value == 5) {
                        setStyle('backgroundColor', 0xcccccc);
                    } else {
                        setStyle('backgroundColor', 0xffffff);
            ]]>
        </mx:Script>
    </mx:Canvas>
    Now just apply the item renderer in the datagrid and that will do it.
    <?xml version="1.0" encoding="utf-8"?>
    <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"  xmlns:ns1="*">
        <mx:Script>
            <![CDATA[
                import mx.collections.ArrayCollection;
                [Bindable]
                private var ac:ArrayCollection = new ArrayCollection([
                    {value : 1},
                    {value : 2},
                    {value : 3},
                    {value : 4},
                    {value : 5},
                    {value : 6},
                    {value : 7},
                    {value : 8},
                    {value : 9},
                    {value : 10}
          ]]>
        </mx:Script>
        <mx:DataGrid x="40" y="36" width="408" height="193" dataProvider="{ac}">
            <mx:columns>
                <mx:DataGridColumn headerText="Column 1" dataField="value" itemRenderer="MyComp"/>
                <mx:DataGridColumn headerText="Column 2" dataField="col2"/>
                <mx:DataGridColumn headerText="Column 3" dataField="col3"/>
            </mx:columns>
        </mx:DataGrid>
    </mx:Application>
    I hope this helps

  • Can I invoke a SubVI in an event? and how do I set the background color of a pipe to #0000ff?

    When I click an image or a glass pipe(which belongs to Industry/Chesmitry category in palette), I want a SubVI to be invoked.
    The purpose is to fetch an OPC-UA data from a web service and to write to it via the service.
    We are building an HMI solution which displays an interactive water plant diagram.
    When users click pipes and motors in the diagram, clicked devices should be turned on and off and change their animations or colors accordingly.
    OPC-UA is for communication with devices.
    I couldn't even set the background color of a pipe to "#0000ff", but setting it to "Red" or "Blue" was possible, and I don't know how to invoke SubVIs in event scripts.
    The documentations in NI.com are confusing and lack depth.
    Even silverlight references are confusing.
    How do I do all of these?

    Hi iCat,
    Can you provide some more information about your current implementation so that we can help to answer your questions. Some questions I have for you are:
    Are you creating this project in the NI LabVIEW Web UI Builder or in LabVIEW?
    How are you publishing your webservice? Is this also in LabVIEW?
    How is your webservice interacting with an OPC-UA server?
    How is the certification set up with OPC-UA so that you can communicate between the server and the client?

  • How do I change the background color of a row in a table indicator?

    Hello,
      How do I change the background color of a row in a table indicator? I know how to change the background color in a active cell, but that is not what I want. My first intent is to make the background color of the first row a unique color, such as green, just to highlight the top row of the table.
    Regards,
    Kaspar
    Regards,
    Kaspar

    I have done this before by using a for loop to change the active cell of a row in order to give the appearance that the whole row is turning the color at once.
