Folder region background color cannot be set

When editing the folder layout properties of a style, you can edit properties of folder regions. One of the options is the background color. When I change this using "apply", the properties window shows a small square with the new color. But when I close the window and edit the properties again, the change is lost.
I hope that changing this color will cause application components (like dynamic pages) to use this as a background color instead of white.
Is this a bug?
Thanks.

It works for me in 3.0.8, but the background color is not used for application components.
Also, as I've recommended in other threads on this forum, you can use URL items displayed in place to display your application components. That gives you more control over the look and feel of the component.

Jerry

  • Dynamic change of region background color

    I have a select list itme on my region. When the user picks a specfic value (based on an Oracle function) in the select list I need to change the background color of the region. What is the best way to do this?

    bobmagan,
    You can use the region "Header and Footer" to do that. But, first of all you will have to create a page process to populate an item in your page with a color code depending on your condition. After that, do this:
    Region Header:
    <div style="background-color:#&P1_ITEM.">
    {code}Region Footer:
    {code:java}
    </div>
    {code}

  • Chance Xfce desktop icon color and folder select background color

    Hi there,
    I'm using Xfce as my DE and I have installed this theme.
    The problem is, because I have a black desktop background I can't see the icon's labels very well. I already tried to change the color with the file .gtkrc-2.0 in many ways, including the one in Arch Wiki, but the problem continues.
    The other problem is, when I select a folder/file in Thunar the background is white, and again it's very difficult to distinguish between selected and not select folders/files. How can I change the background color? (This one I have no idea of how to make).
    Thanks in advance.

  • Setting a default background color

    Hi All,
    I would like to set a default background color for all the
    components that I'm going to draw. What is the best
    way to achieve this?
    Thanks.
    Syed

    You can set using UIManager of the Look and Feel.
    UIManger.put("Button.background", Color.blue);
    will set the color of all the JButtons to blue. Like that you can change for all the components you need.

  • GoLive CS2 won't set background color

    I have GoLive CS2 by way of investing in the whole CS2 package, so it wasn't a standalone installation. I have installed all of the recent updates.
    I go to Properties to set the background color. It sets it to "Black" in the HTML code, but it doesn't show up either in GoLive or in my web browser when I preview it. I also tried setting the black hex value "000000", and that has the same problem. It won't do any other colors, either.
    I can set the bg color to things like a layout grid, but that doesn't really solve my problem.
    What gives, Adobe?

    I do, and I didn't tamper with it. However, I found a solution to my problem last night. It was still clearly a bug, but I got around it. I started a new website document (for some reason, it didn't work the first time I tried), and that worked.
    Thanks for the idea, though. I'll be sure to check that, in the future.

  • Is there a global background color setting for all apps?

    This pertains to a DESKTOP  COMPUTER uisng 10.7 (Lion) - not  iPad or iPhone or iXyz
    I've spent the last half hour on the forums but each talk about a SPECIFIC application's background.  I'm tired of staring into a WHITE lightbulb when switching applications.   Most professional applications (like final cut pro or photoshop) have a dark grey or beige background that is restful on the eyes.     That is usually easily set by navigating preferences.   Top web pages know how to use dark backgrounds to make the colors really stand out.
    My question pertains to a GLOBAL setting so that ALL applications have the same background color (unless specifically set within).   Windows had this for over a decade.  Is Mac behind Windows?   Seems like this should be under Settings==>Display or Desktop (but I can't find it).  
    I've seen discussions about creating a rectangular window (I presume in Photoshop) then saving it as "template" -- but there is no save-as "template" setting in Photoshop or WHERE to put it -- or active the template.   Lots of missing instructions if so.
    This ain't rocket science fellas -- could one of you geniuses point me in the right direction with some SPECIFIC navigation (ie: go here, click this, save that, do this).
    Thanks for your time & thoughts.
    -Dale

    You're confusing being behind Windows with "don't want to". I'm sure Apple's engineers could add the ability for users to play with the desktop theme if they wanted, but they choose not to. They never have.
    However, there are third party options for that. This one looks pretty interesting. Flavours is another.

  • Wrong command button background color on web

    Hello.
    We have a problem with background color of command button.
    If we set background color to lime, only upper line of button is in lime color. Rest of the button is in default color.
    This happens when user runs application on web (standalone server and embedded).
    In jdeveloper button is in correct color (whole button in lime color).
    What could be the problem?
    Thanks.

    On debugging, i found that the commandButton is using background-image to show the silver/grey background.
    So, in order to modify it to other background color, you have set the background-image as none as follows:
    <af:commandButton text="commandButton 1" id="cb1"
    inlineStyle="background-color:red; background-image:none"/>
    Thanks,

  • The Case of the Indecisive Background Color

    After browsing the vast space of discussion topics in hopes of some clue that may lead me to salvation, the course of action has come to posting my problem to the collective community. I know very little about macs, but am learning slowly, unfortunately, through these little problems which I find myself often mystified.
    When I select a background color to be set to an individual window it does not obey my command. The insubordination comes when I click off to another window and then back again(note I have my window settings to open all in the same window). When I do click back the window is some obscure, and often ridiculous, color which leaves reading hard on the eyes. When I leave the window on plain white there is no problem aside from a lackluster appearance. On occasion, when I mess around with it, selecting a color will actually offset other colors form other windows.
    This problem has been ongoing for about six months, though not a huge annoyance, I would like to solve this riddle of pigments. If something is unclear about this situation I'll answer any questions, but as I said I've only a year under my belt with this computer and am low on the totem of knowledge. I appreciate anything information that would alleviate this predicament. Thank You.

    unfortunately that did not work. however, i have noticed something new. when i click on the sidebar icons down the line, e.i. application, music, movies, picture... the colors will cycle through different patters. In the beginning I had all of my window colors red, so some of the time they resemble a shade of red. If i click on those windows they will be red and then reclick back to applications they will start with a green and so on. it seems like there is some confusion going on with the computer.

    Instead of extending JCheckBox, extend JPanel... put a checkbox in it. (border layout center).
    Or better yet, don't extend any gui component. This keeps things very clean. Don't extend a gui component unless you have no other choice.
    private class MyCellRenderer implements TableCellRenderer {
        private JPanel    _panel = null;
        private JCheckBox _checkBox = null;
        public MyCellRenderer() {
            //  Create & configure the gui components we need
            _panel = new JPanel( new BorderLayout() );
            _checkBox = new JCheckBox();
            _checkBox.setHorizontalAlignment( SwingConstants.CENTER );
            // Layout the gui
            _panel.add( _checkBox, BorderLayout.CENTER );
        public Component getTableCellRendererComponent(JTable table, Object value,
            boolean isSelected, boolean hasFocus, int row, int column) {
            if( isSelected ) {
               _checkBox.setForeground(Color.white);
               _panel.setBackground(Color.black);
            } else {
               _checkBox.setForeground(Color.black);
               if( row % 2 == 0 ) {
                  _panel.setBackground(Color.white);
               } else {
                  _panel.setBackground(new Color(239, 245, 217));
            _checkBox.setSelected( Boolean.valueOf( value.toString() ).booleanValue() );

    Hi
    A couple of things...
    Thats SQL - not PL/SQL
    That is not a valid SQL statement, I'm surprised its not giving an error. Please post the exact region source.
    When posting code on the forum, put {noformat}{noformat} (with the curly brackets and the word code in lowercase) above and below your code like this...
    {noformat}{noformat}
    SELECT *
    FROM emp
    {noformat}{noformat}
    It will then appear like this... SELECT *

  • How to set the Background Color of a Text Field in a Tabular Report.

    Hello,
    I tried to set the Background Color of a Text Field in a Tabular Report.
    But I was not able to change this colur.
    In the report attributes --> column attributes
    I tried already:
    1. Column Formating -- >CSS Style (bgcolor: red)
    2. Tabular Form Element --> Element Attributes (bgcolor: red)
    but nothing worked.
    Can anybody help me?
    I Use Oracle Apex 2.2.1 on 10gR2
    thank you in advance.
    Oliver

    in "Report Attributes" select the column to move to the "Column Attributes" page. In the "Element Attributes" field under the "Tabular Form Element" region enter
    style="background-color:red;"
    I will also check if there is a way to do this via the template and post here again
    edit:
    in your template definition, above the template, enter the following:
    < STYLE TYPE="text/css" >
    .class INPUT {background-color:red;}
    < /STYLE >
    (remove the spaces after the < and before the >)
    change "class" to the class that the template is calling
    (I'm using theme 9, the table has: class="t9GCCReportsStyle1" so I would enter t9GCCReportsStyle1)
    A side-effect of using this second version is that ALL input types will have a red background color--checkboxes, input boxes, etc.

  • Problem dynamically setting row background color in a report

    Hi guys,
    I want a PPR Classic SQL Report to dynamically show a background color depending on what value is stored in the column of the record.
    To illustrate what I've tried consider the following:
    1. I created a PPR Report on DEPT (this is the report I want to use with record backgrounds)
    2. I created a PPR javascript call that I trigger somewhere in the page
    function refreshReport(pField, pValue){
      var region = $v('P2_DEPT_RID');
      var link ='f?p=' + $v('pFlowId') + ':' + $v('pFlowStepId') + ':' + $v('pInstance') +'::::' + pField +':'+ pValue;
      html_PPR_Report_Page(this, region, link);
    The updating of the report works fine by the way.
    3. I changed the code in the HTML Expression of the column definition of "DNAME" of the DEPT report. I used jQuery to set the class of the <tr> element of the position the field is in.
    This is the value I want to dynamically check on
    <div id="dept_#DEPTNO#">#DNAME#</div>
    <SCRIPT type=text/javascript>
    $('#dept_#DEPTNO#').parent().parent().children().removeClass('t20data');
    if ('#DNAME#' == 'RESEARCH'){
          $(function(){    
            $('#dept_#DEPTNO#').parent().parent().addClass('voorhaal_kan');
    }else{
             $(function(){    
                $('#dept_#DEPTNO#').parent().parent().addClass('sscc_ok');
    </SCRIPT>4. I created some CSS like so:
    tr.voorhaal_kan{border:1px solid #AAA;border-left:none;border-top:none;background-color:#FFDD44;padding:2px 8px;}
    tr.sscc_ok {border:1px solid #AAA;border-left:none;border-top:none;background-color:#CCFFCC;padding:2px 8px;}
    tr.sscc_manco {border:1px solid #AAA;border-left:none;border-top:none;background-color:#FF3300;padding:2px 8px;}
    tr.sscc_geel {border:1px solid #AAA;border-left:none;border-top:none;background-color:#FFFF66;padding:2px 8px;}Now the problem is, the first time I load the page, the javascript in the HTML Expression works fine! It checks the value, and colors the <tr> beautifully. But, when i Refresh the report using PPR (calling the javascript function), the report is reloaded just fine, but the javascript bit in the HTML Expression is skipped for some reason resulting with a regular background color found in "t20Standard td.t20Data" . Alerts won't fire either in the code, hence the assumption of the code skipping.
    Any ideas on how this problem can be solved?

    Hey Rutger,
    I know you've already done a lot of work in another direction, but would it be possible for your purposes to use the SQL to do what you need. check out this link:
