How do I change the colour of text in a cell in a JTable?

I am trying to change the color of the text in a single cell in a JTable. I have tried not adding a cell renderer and it changes the colour of text in all cells.
I have tried adding a cell renderer to the table and it does the same ie all cells text colour changes.
I am able to add a cell renderer to a column and it changes all the cells in the column.
I cannot figure out how to change just one single cell's text colour without effecting the other cells.

Ok, so if i create my own cell renderer do I set it as the default renderer for the whole table i.e.
table.setDefaultRenderer(MyCellRenderer, renderer);
Does this set one cell renderer for the whole table or is there an individual one for each cell?

  • How do I change the colour of text in a JTextArea?

    I was wondering if there is a method I could use to change certain parts of the text in a JTextArea to a different color, eg if you wished to highlight HTML tags in the source code, so they stand out from the rest of the text.
    cheerz

    Try this...
      // create text area
      JTextArea textArea = new JTextArea();
      // change text color to blue
      textArea.setForeground(Color.blue);
      // change background color to black
      textArea.setBackground(Color.black);

  • How to change the colour of text property in Radio button?

    Hello All,
    I am having some radio buttons in my application. i want to change the colour of text property by default it is black.
    Could any one please suggest me how to do it?
    Thanks in advance.

    Currently you cannot, it is a known (and hopefully reported, and at least addressed for next version) bug (or limitation, as they rushed to get the components out before JavaOne...).
    People reported they just put an empty text and put a label beside the component. Ugly workaround (bad when the component will be complete) but if it works... :-)

  • How can i  change the column label text in a alv table display

    how can i change the column label text in a alv table display??
    A similar kinda of question was posted previuosly where the requirement was the label text was needed and following below code was given as solution :
    <i>*  declare column, settings, header object
    DATA: lr_column TYPE REF TO cl_salv_wd_column.
    DATA: lr_column_settings TYPE REF TO if_salv_wd_column_settings.
    DATA: lr_column_header type ref to CL_SALV_WD_COLUMN_HEADER.
    get column by specifying column name.
    lr_column = lr_column_settings->get_column( 'COLUMN_NAME1' ).
    set Header Text as null
    lr_column_header = lr_column->get_header( ).
    lr_column_header->set_text( ' ' ).</i>
    My specific requirement is i have an input field on the screen and i want reflect that value as the column label for one of the column in the alv table. I have used he above code with slight modification in the MODIFYVIEW method of the view since it is a process after input. The component gets activated without any errors but while run time i get an error stating
    <i>"The following error text was processed in the system CDV : Access via 'NULL' object reference not possible."</i>
    i have checked in debugging and the error occured at the statement :
    <i>lr_column = lr_column_settings->get_column( 'CURRENT_YEAR' ).</i>Please can you provide me an alternative for my requirement or correct me if i have done it wrong.
    Thanks,
    Suri

    I found it myself how to do it. The error says that it is not able to find the reference object i.e  it is asking us to refer to the table. The following piece of code will solve this problem. Have to implement this in WDDOMODIFYVIEW method of the view. This thing works comrades enjoy...

    I looked into this before, and at the moment there is little you can do to customize the inputrender tag, short of subclassing it and adding the functionality you require

  • How do I change the color of text in Messages?

    How do I change the color of text in Messages? It was easy to do before, but I can't seem to find it after the upgrade.. is it a hidden menu option?  The gray text is really annoying.

    Two possible ways are available
    Set the text with and html text string like "<html><font color-red>" + text + "</font></html>"
    or get the cellrenderer, cast to the DefaultCellRenderer and call setForeground or background or implement or your own cellrenderer to do the custom coloring (this could maybe depend on indexes)

  • How can i change the sequence of text element in standard driver program ?

    Hi,
    can u tell me how can i change the sequence of text element in standard  sapscript driver program.. without making a zcopy of standard driver program.
    My problem is when MEDRUCK form is getting printed for PO print , header text is coming before item. But the requirement is to come it after item.So how cani do that without making the zcopy of  SAPLMEDRUCK program..Is there any enhancement point in SAPLMEDRUCK driver program..where i can put my customise code for changing the sequence of text element ?

    Hi,
        Just copy the MEDRUCK to ZMEDRUCK. No need to copy the driver program.
    1) SE71Menu > Utilities > COpy from Client
    MEDRUCK ->>Client 000
    New formname ZMEDRUCK
    2) Now open the ZMEDRUCK in DE language in SE71
    3) Menu > Utilities > Convert original Language
    Change DE  to EN, save and activate
    4) Now open the ZMEDRUCK in EN language
    5) Goto Pagewindows > Main window,
    Look for the HEADER text Text element, copy the whole code under this Text element just after the ITEM text Text element, and comment the HEADER text above.
    Now the Header text Text element will be below ITEM text only. This will full fill your requirment.
    Now goto NACE transaction and add the copied ZMEDRUCK to the EF application.

  • How do I change the colour of a page in Pages without using a floating shape or text box?

    I want to change the colour of a page in Pages without having to stretch out a floating coloured shape or using a text box to write the text in. I have been stretching shapes and using text boxes for years but surely there is an simpler and more elegant way to do this? Plus, I want to be able to type several pages of continuous text and not have to split the text up into multiple text boxes. Any help most welcome.

    There are a whole lot more really essential features missing in Pages than this.

  • How do you change the colour of the text box?

    A lot of the text box options seem different for DC. Is there a way to change the colour of the text box that you create/the borders etc.?
    In the past, you would just press Ctrl+E and a toolbar would pop up so that you could fiddle w/ the colour of the background etc. This seems to be gone.
    Thanks for your help!

    Hi, Rahul,
    Thank you for replying back.
    Unfortunately, I have tried what you have suggested and the only thing that I get is a box that says "Properties: No current selection."
    Could you please possibly see what it is that I am doing wrong?
    I created the text box, wrote whatever inside, clicked somewhere outside the box and then clicked on the text box and I still only get "Properties: No current selection."
    Thank you,

  • How do I change the colour of a PS frame?

    I am creating christmas cards and adding photos of my kids onto christmas backgrounds. I am dragging frames from the right hand side but want to change the colour of these frames - can someone please tell me how to do that?
    I've worked out how to do it by clicking on the black/white circle and using the hue/saturation but when I go to do that with the frame on the new background, the colour of the background changes instead of the frame. I need to change the frames colour while on the background to get an exact match to what I want (does that make sense???)
    Is there an easier way to create a frame for the photos? I also want to create a text box / frame (with the christmas message) with a solid colour background (different to the main background) can anybody tell me how to do that?
    An example of what I am trying to do is here http://www.invitations2impress.com/christmas-cards-gift-tags
    Thanks in advance )

    In a nutshell, you have to simplify the frame layer and erase the interior.
    Here are the steps:
    Create your background.
    Add a new layer:
    Drag the frame you want to use onto the editing surface.  The frame will come in on its own layer:
    Simplify that frame layer:
    Choose the Magic Wand Tool and give it these settings:
    Click on the interior gray area of the frame with the Magic Wand to select it, and hit your Delete key:
    Switch to the Eraser Tool and erase the stuff that's left in the middle:
    Select the empty layer (Layer 1 in this example) and use File...Place to place your image on it.  The layer name will change to the name of the image.  Adjust the size and placement of the image.  Your layers will now look like this:
    With the frame layer selected, add a Hue/Saturation adjustment layer, making sure to "clip" it to the frame layer.  Adjust the sliders to suit:
    The final result:

  • How do you change the colour of the "colour boxes" in themes?

    Creating a book in Aperture the various "Themes" offer you different layouts.  When you are in a Theme - is there a way to change the colours of the background boxes (Not page colour) - I have searched everywhere to see how to do this and a simple thing like this seems like it is not possible.  Yes you could make a photo of the correct colour you want and drag it in but surely there is a simple way of changing the colour of these theme boxes. 
    The theme I am using is Special Occasion and I want to darken the lightblue boxes behind the text. 
    Would appreciate anyone out there who could advise on this please, thank you in advance.

    Richard,
    there is no built-in option to change the color boxes. You can only change them by patching the Resorces in the Aperture application bundle, and that is risky.
    The color of the background boxes is set in the property list (for the Extra Large Book):
    /Applications/Aperture.app/Contents/Resources/Book Themes/Special Occasion/ExtraLarge/Graphics/BlueRect.plist
    The current value is:
    backgroundColor {224, 241, 238, 100}
    To try what happens, when this value is changed, I edited it to {100, 200, 255, 100}
    You will not really want to patch your Aperture application bundle
    What you might try, would be to copy the "Special Occasion" subfolder of the Book Themes and to create your own custom theme from this and install it in your user library
    ~/Library/Application Support/Aperture/Book Themes/

  • How can I change the colour of the tools?

    I want to change the colour of the blue box next to the word diabc. The blue field is a tool with you can change the text. I know how to change one field at a time but I want to change the standard settigns, so that I don't have to change it field for field. I can't find it anywhere. I have found some information about changing the tool bars, but you can't change this tool I use. Only others.
    Who can help me? I have Adobe Acrobat 9 pro extended. I use the Dutch version, so some things may have a different name.
    I have included some pictures.
    If you have any questions, just ask. 

    Thanks for your help so far.
    I hope you can see it now. It's a bit difficult to make a picture from my print screen, because I don't have the right programs at my computer at work.
    The menu is in Dutch. But I don't have so many options as you have. If I go to 'eigenschappen' (in English properties) I get this menu. In this menu you can change the colour, but Adobe doesnt' remember this, so you have to change it every time. And that's quite a lot of work if you want to do this. Because I have to review a document of 40 pages.
