How to change width of separating lines of cells

Could u explain me how can I do to make the lines into jTable less wide.
Thanks a lot.

Could u explain me how can I do to make the lines into jTable less wide.The lines between the rows and columns are only 1 pixel wide so I'm not sure how you make them smaller. You can prevent the painting of the lines by using:
table.setShowGrid(false);
table.setIntercellSpacing(new Dimension(0, 0));

  • How to change data symbol color - line charts

    In the keynote manual to change the color of lines they say you have to the graphic inspector and change the color of the line there, but that does not change the color of the data symbol (circle, triangle,...) How to change its color ?
    thanks

    The internal part of the dot can be changed simply by dragging a color from the Color Picker onto the dot or triangle.
    You can do the same to change the color of the line.
    I can find no way of actually changing the outer part of the data symbol.
    The User Guide seems to not mention the subject at all.

  • How to change color of a line on a graph

    Bonjour à tous,
    I want to change the color of line in a graphic, but i dont know how to do.
    Thanks for your answer

    change the Color Scheme on Chart Attributes page to Custom then put a comma seperated list of colors in the Custom Colors text area of Chart Attributes of your chart. For example, if you have 2 line series in the chart then you could put db15db,DD0000 in Custom Colors text area
    DD0000 is actually a color in hexadeccimal number format
    FFFFFF stands for white and 000000 stands for black. You also get to pick colors from a color picker in  Chart Attributes page

  • How to change default decimal separator

    Hi,
    what is the problem with the code below ? The output is 1234.5 however, I need it to be 1234,5
              String itemFormat="%4.1f";
              Double x = 1234.5;
              Locale dl = Locale.getDefault();
              DecimalFormatSymbols dfs = new DecimalFormatSymbols(dl);
              dfs.setDecimalSeparator(',');
              System.out.println(String.format(dl, itemFormat, x));It is testing code, however I need to use % formating, and I need to use String.format function.
    So, my question is - how to change the locale for String.format function ?

It would be best to change actual user locale... but I wonder if this is possible...I think the java runtime determines the locale it is in by querying the operating system. This becomes the "default" locale. So if the machine knows where it is, so will the java runtime, and doing getDefaultLocale() should work seamlessly.

  • 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"/>

  • Change width in draw line for LabVIEW 6.1

    Hi
    as I couldn't solve the problem up to now I'm posting this question again with the hint that I'm looking for a solution in LabVIEW 6.1. LV 7 has already a SetPen.vi where the style and the width can be chosen.
    Link to the other posting
    Original Text:
    HI!
    I wanted to draw thicker lines in a picture control in LabVIEW 6.1. I found some posts where they mentioned that I have to edit the according VIs. So I played a bit around but didn't get it working. I'll attach pictures of the diagrams of "SetPen.vi","DrawLine.vi" and "Draw
    MultipleLines.vi". Can anybody tell me what to change or provide a suitable vi? Is there a tutorial where the code and the generation thereof for picture controls is explained?"

    Andy,
    The format and specifications for the picture data type and unfortunately not published for public use. The supportability of the picture data type only extends to the functionality provided in the corresponding VI�s shipped with LabVIEW. You are welcome to play around with how it works, but know that it is not supported. I hope this does not provide too much of an inconvenience.
    Have a great day!

  • Report Painter: How to change the order of lines in selection screen

    Dear Gurus on Report Painter,
    how can I change the order of the lines (where the values for the variable selection of my cost center report are entered) in the selection screen of a report painter report? The Selection screen looks awful.
    Is there also a possibility to add another description to each line of the selection screen?
    Thank you very much for your advice.
    Best regards Timo

    I am afraid you have much choice in choosing the order of the selection parameters. However, with the developer's access you may.
    This is how!
    Step 1: If it is a standard report, copy to your own report. and assign it to a report group. and execute.
    Step 2: When you execute, and the selection appears, go to systems>status and here , copy the program name (it may look something like GP46LP6VEDORBSA2IHWYSR4TL58020)
    Step3: Go to SE38 and enter the above derived program name with a view to re-arrange the line withing the program, with reference to selection parameters. 
    For example: I have a selection screen in the following order:
      Controlling area            
      Fiscal Year                 
      From period                 
      To period                   
      Plan version                                                                               
    Cost center group           
      Or value(s)                 
      Cost element group          
      Or value(s)                 
    The corresponding program that drives this order is in the program and would look like this,
    SELECTION-SCREEN BEGIN OF BLOCK VALUE_SELECTION
                     WITH FRAME TITLE TEXT-003.
    <b> PARAMETERS: $1KOKRE  LIKE CCR1S-KOKRS .
      PARAMETERS: %1KOKRE  LIKE CCR1S-KOKRS MODIF ID IN4.</b>
    <b><i> for controlling area</i></b>
      PARAMETERS: $1GJAHR  LIKE COSP-GJAHR .
      PARAMETERS: %1GJAHR  LIKE COSP-GJAHR MODIF ID IN4.
    <b><i> for fiscal year</i></b>
      PARAMETERS: $1PERIV  LIKE COSP-PERBL .
      PARAMETERS: %1PERIV  LIKE COSP-PERBL MODIF ID IN4.
    <b><i> for period from</i></b>
      PARAMETERS: $1PERIB  LIKE COSP-PERBL .
      PARAMETERS: %1PERIB  LIKE COSP-PERBL MODIF ID IN4.
    <b><i> for period to</i></b>
    etc.
      PARAMETERS: $1VERP   LIKE COSP-VERSN .
      PARAMETERS: %1VERP   LIKE COSP-VERSN MODIF ID IN4.
      PARAMETERS: $1VALUTP LIKE CCR1S-VALUTYP MODIF ID IN4 .
      PARAMETERS: %1VALUTP LIKE CCR1S-VALUTYP MODIF ID IN4.
    SELECTION-SCREEN END OF BLOCK VALUE_SELECTION.
    ......... set variables ..............................................
    SELECTION-SCREEN BEGIN OF BLOCK SET_SELECTION
                     WITH FRAME TITLE TEXT-004.
      PARAMETERS: $1KOSET  LIKE RKSB1-KSGRU.
      PARAMETERS: %1KOSET  LIKE RGSBS-SETNR MODIF ID IN5.
      SELECT-OPTIONS _1KOSET  FOR CCR1S-KOSTL .
      PARAMETERS: $1KSTAR  LIKE RKSB1-KAGRU.
      PARAMETERS: %1KSTAR  LIKE RGSBS-SETNR MODIF ID IN5.
      SELECT-OPTIONS _1KSTAR  FOR CCR1Z-KSTAR .
    SELECTION-SCREEN END OF BLOCK SET_SELECTION.<i></i><b></b>
    If you want fiscal year to appear first, you try just copying the coding relating to fiscal year just above the coding for Controlling area.
    Extend the same logic for what you may want to get.
