Force Background Color

I've inherited a help system that uses a single CSS (RoboHelp
7). Some of the topics have a custom yellowish background; others
do not. Is there a way to select all files in the Topic List and
force them to have a white background? I've tried changing the
style sheet (using the Format | Styles command), but that doesn't
work. I can, of course, use the Borders and Shading control to
change each individual topic. That's going to kill me, though!
Isn't there a global setting?

Hi there Semicolon1
This would seem to imply you have a bunch of topics that use
embedded styling. It's best to try and remember that CSS has a
hierarchy. The linked CSS file should be used to control as much of
your formatting as possible.
Each topic may have coding that will override the externally
referenced CSS file. If this is the case there is unfortunately no
choice but to hand edit the offending topic(s) to remove the
formatting. So if your CSS file specifies a background color of
yellow but specific topics always display baby blue, the topics
with baby blue probably have embedded code that overrides the CSS
file. You will need to edit each of these topics individually.
Sorry, but there is no way other than to use a global find and
replace tool to change these topics.
Hopefully this helps... Rick

JTree custom renderer setting selection background color problem

Hi,
I have a JTree with a custom icon renderer that displays an icon. The JTree is part of a TreeTable component. Iam having a problem setting the selection background uniformly for the entire row. There is no problem when there is no row selected in the JTable.
My present code looks like this:
Iam overriding paint in my renderer which extends DefaultCellRenderer.
     super.paint(g);
        Color bColor = null;
        if(!m_selected) {
             if(currRow % 2 == 0) {
                  bColor = Color.WHITE;
             } else {
                                                bColor = backColor;
        } else {
             bColor = table.getSelectionBackground();                  bColor = getRowSelectionColor();
     if(bColor != null) {
                       g.setColor(bColor);
         if(!m_selected) {
               g.setXORMode(new Color(0xFF, 0xFF, 0xFF));
         } else {
             g.setXORMode(new Color(0x00, 0x00, 0x00));
              I have a color I arrive at using some algorithm that I want using method getRowSelectionColor(). The other cells in the row have this color. But the cell containing the tree node shows different color. Iam not able to arrive at the right combination of the color to set and the xor color so my tree node also looks like the other cells in the row.
It is not a problem really as the table still looks good. Its just that the tree node looks like it has been highlighted and this might cause a problem when a table cell is highlighed later on in the application ( two cells in the row would be highlighted causing confusion).
Any help would be appreciated.

Hi Camickr,
Thanks for the reply. Iam sorry I didn't include the sources the first time around. There were too many of them. I have created a small, self-contained, compilable program that demonstrates the problem and including it herewith. Still there's quite many files but they are all needed Iam afraid. The only one you will have to concern yourself fior this problem is the file IconRenderer.java. The treenode background and the other cells background are not in sync when table row is not selected in this example though. But they are in my real program. I just need them to be in sync i.e have the same background color when the row is selected.
Your help would be very much appreciated.
These are the files that are included below:
1. AbstractTreeTableModel.java
2. Bookmarks.java
3. BookmarksModel.java
4. DynamicTreeTableModel.java
5. IconRenderer.java
6. IndicatorRenderer.java
7. JTreeTable.java
8. TreeTableExample3.java (contains main)
9. TreeTableModel.java
10. TreeTableModelAdapter.java
The copyright and javadocs information has been stripped for clarity.

Can the current line be highlighted using a background color or have the cursor flash?

I use the split screen and left click in the Design pane to jump to where I want to be in the Code pane in Dreamweaver CS6. The problem is that it can be very hard to tell where the cursor is in the Code pane since the cursor doesn't flash.
Is there a way to force Dreamweaver CS6 to change the background color of the currently selected line or at least have the cursor flash in both panes? There must be some way to make it easier to find the current line of code.
Thanks.

John Waller wrote:
The cursor does not flash in Code View only when Code View is not in focus i.e. you're working in the Design View window in Split View.
In those caases, I just highlight a word or two in Design View and the corresponding words are highlighted by DW in Code View (even when Code view is not in focus).
Thanks. I've been doing that, but sometimes there is no text to highlight. I hoped Dreamweaver might have a hidden setting that I could enable. That's a lot of extra sliding of the hand/wrist for no good reason when it would be easy for the Dreamweaver programmers to change the background color of the current line or make the cursor flash or do something else to indicate where you are in the code besides making the user constantly make a smearing action with the mouse. All of those extra movements add up the wear and tear when you're trying to avoid getting a repetitive stress injury, especially if you already use mouse gestures in a browser.

[SOLVED] Gnome notification area has wrong background color

I'm using the Shiki-Brave theme on Gnome and all (yes, all) of the tray icons have the wrong background color. The color changes slighty if I select another Shiki theme, but is pretty close to the default gray. Strangely, I only have this issue on my desktop at home -- none of my other machines (two laptops and a desktop at work) exhibit the problem. I have ensured that the theme is exactly the same on all machines. Another oddity is that other themes (e.g. high contrast inverse) have the right background color!
The only thing I have managed to find via Google is a bug report against Gnome. Here is what I have tried:
* Removing and readding the applet to the panel.
* Blowing away all my settings (rm -rf .gnome2 .gconf .gconfd .local) and setting things up again. To be sure I did not miss anything, I also tried creating a new user with a clean home. Still the same issue.
* Removing and reinstalling all of the gnome and gnome_extra groups. I even cleared the pacman cache to force a redownload.
Any ideas? I'm at a loss on what to try next.
Thanks!

I figured out the problem.
I have an NVIDIA card and I recently modified my X server to use Xinerama instead of TwinView. Xinerama was responsible for all this nastiness. Reverting to TwinView fixed the problem (and some other weird ones that started popping up).
Those of you with NVIDIA cards, avoid Xinerama!

Defining a background color for a paragraph style

Hello and please excuse this very basic question, but I am completely stumped.
How do I simply define a background color for a paragraph style? I cannot use a table etc. because the styles are mapped during an XML conversion. Code lines should receive a gray background box to separate them from the text.
Also, is there a way to force line breaks whithin words for a specific style? The text, formated in Courier, should just fill the space with a fixed width per character and break wherever the line ends.

With some drawbacks it's doable using two paragraph tags.
The first tag, e.g. "Line" is empty (no text), and it has a reference page graphic that's just a rectangle filled 100% with color and set to have a percentage tint so that the text will "show through" it.
"Line" is also set to have a negative space below it, e.g. -12 points.
"Code" paratag has the actual code text in it, and it's set to have a negative space above, e.g. -12 points.
I've done projects where I have multiple Line paratags differing by the number of code lines needing to be shaded, e.g. Line1, Line2, Line3.
Unfortunately there isn't a way to automatically have the line expand to the correct depth of the Code paragraph, although I believe this would probably be something that could be done as a Framescript, to run through a document and create new "line" paratags of the correct depth depending on how many Code paragraphs or lines are in the following paratag.

GPO to set display background COLOR

Need to set the display background color with a group policy. Found what seemed a good example to follow but nothing happens.
http://serverfault.com/questions/213641/how-to-force-background-colour-with-gpo-centred-wallpaper
Any assistance is appreciated.
Windows 7 sp1 PC

You could create a theme that includes the background of your choice, then share it using group policy. Follow these steps to create the theme:
http://www.winhelponline.com/blog/share-theme-with-all-users-windows-7/
The Windows 7 GPO to "Load a specific theme" is under User Configuration --> Administrative Templates --> Personalization, which can be set to point to a shared location that contains the theme. The drawback here is that existing user
profiles will ignore this setting. Only new users logging into the workstation for the first time will execute it. So to convert existing users, you would need to push out a registry change that points to the new theme.
In addition, you can also set "Prevent changing theme" and "Prevent changing desktop background" to keep the settings locked.

Htmltext background color

Hi.
My problem is: I need support for styling text background color inside htmlText property of a Text (or TextArea) control, for text that is marked up with html tags.
I am aware that Flex's htmltext only supports a subset of actual HTML tags:
<font color='#ff0000'>the text</font> is supported
<font backgroundColor='#ffffff'>the text</font> is not supported
And this is a problem for me because I absolutely need to be able to change the background color for certain words in the text. I searched a lot for a solution with no success. The only thing I see that supports background color is the TextField object, but I have no clue how I would implement it in the same manner as the Text or TextArea control. Does anyone have any suggestions?
(compounded with this is that rather than use: <font color='#ff0000' backgroundColor='#ffffff'>the text</font>, the text is marked up with <span id='group1'>the text</span> tags, and these CSS IDs are being processed with a stylesheet object in actionscript. So ideally, the solution should also work with stylesheets, but I can work around it if I'm forced to resort to hardcoding in the HTML tags.)
Thanks for your attention.

Thanks, but I want to change the background color only in one
word, not all of the text.

Please Help with background color problem in loaded .swf

I am stuck!
This is Flash CS4...
I created a flash application which loads in many other little flash applications (.swf files) based on menu selections.
When I change one of the little applications the changes are viewable except when I change the background color.
After the first time I view the application, the background color changes do not carry over to the main app. I run the little ones stand alone and they show the new color, then I run the main app and any other changes I have made are there but not the color change. When I remove the file and the load fails, the old backround color still displays in the container movie clip the .swf was previously loaded into.
I have tried several different options and the only thing that worked was renaming and copying and deleting and making a big mess. There has to be a way to force a refresh of this mysteriously saved color. doesn't there?
Please help!
Thanks!
Vivian

Hi Antonia
I am loading the swf into an instance of a movie clip:
var myLoader:MovieClipLoader = new MovieClipLoader();
myLoader.loadClip("Capitalization.swf", contCapitalization);
it is the background of Capitalization.swf that will not change
this is AS 2 since the app was created before I upgraded
Any ideas?

Change default background color in Dynamic pages

Anyone knows how to change the default background color of a

I try to force the the background color placing the html tag
<td bgcolor=#FFFFFF> but there is still a beige strip at the
left side of the table.

Hi Richard,
For about how to inspect page element, you can use IE Developer Tools:

Portlet Background Color Disappears when displayed

Hi,
I am using ver 9.0.4.0.99 of Portal and I'v created several Navigation Pages for the top banner and footer of my pages.
The banner is divided into two regions each holding an image. To 'fill in' the white space that surrounds the images I've specified a background color (blue) in a 'banner style' and added it to each region of the Navigation Page.
When we look at the Navigation Page alone, all looks well, but when we add the Navigation Page as a portlet to our root page in a banner region, the background color just disapears. I am left with two images surrounded by
whitespace.
I have just recently done the same process (nav pages with separate styles) in version 9.0.2.6 with another company and I did not have this problem. It worked fine. I even went back to make sure I followed the exact same steps and settings.
Has something changed with this version (9.0.4.0.99)?
Any ideas what we are doing wrong? Thx for your input.

In the properties for your navigation page, on the Others tab, ensure the "Use Style Of Page On Which Portlet Is Placed " checkbox is unchecked. This should force it to use the style you picked in the banner page and not on the display page. Please note this checkbox only has affect on item regions in the navigation page. Portlet regions on the navigation page will take the colors from the style on the display page.
Hope this helps,
Candace

Background color of a list item implemented as Tlist

Hi,
I have one form with 3 blocks each holding one list item. The list item that has the focus should have a different background color from the other 2 list items. I thought to implement this with visual attributes I assign in the when-new-block-instance trigger. This however only partially works.
What happens is the following :
At startup focus is in the first block. This block's when-new-block-instance trigger is fired :
SET_ITEM_PROPERTY('BK_LIST.LIST',VISUAL_ATTRIBUTE ,'VA_INDICATOR');
SET_ITEM_PROPERTY('BK_LIST2.LIST',VISUAL_ATTRIBUTE ,'VA_ENABLED_LIST');
SET_ITEM_PROPERTY('BK_LIST3.LIST',VISUAL_ATTRIBUTE ,'VA_ENABLED_LIST2');
and the list correctly gets it's yellow background. (defined in va_indicator)
Va_enabled_list and va_enabled_list2 both have a white background, difference between them is the font size)
Now when we move focus to the 2nd block we get a different behaviour. This is the trigger defined on the 2nd block :
SET_ITEM_PROPERTY('BK_LIST.LIST',VISUAL_ATTRIBUTE ,'VA_ENABLED_LIST');
SET_ITEM_PROPERTY('BK_LIST2.LIST',VISUAL_ATTRIBUTE ,'VA_INDICATOR');
SET_ITEM_PROPERTY('BK_LIST3.LIST',VISUAL_ATTRIBUTE ,'VA_ENABLED_LIST2');
So I except the first block to get a white background again and the second block to get it's yellow background. However only the selected row in the tlist changes it's background color. (this in both blocks)
I do not understand why the first time (at form startup) the background color is set for the whole item and the second time only for the selected record.
I tried to use the property background_color but the colors are different from what I see in my color palette in that case. If I use the same color codes I also use in my visual_attributes the final result on the screen is different...
Secondly the result is the same, at form startup the item's background is set, as from the second call only the current salected record in the tlist will change from background color.
Forms are running C/S and are developed in Forms 6i. One way to get the result I need is by navigating back & forward to my application in Windows using Alt-Tab. At that moment the correct background colors are suddenly applied... Is there a way to force a similar sort of screen refresh ?
Thanks for any hints, workarounds, tips or solutions !
Kris

Hi,
I still don't have a clue how I could solve this one.
It works leaving the block (so making it white again) but it does not work entering the block. (giving the list item another background color). The problem is not about the whithe color. If I do my tests with other colors (red-yellow) the problem remains.
Best Regards,
Kris

Div background color

hi:
PHP, MySQL
i have a master page where each row is displayed using an
inline list
with text pulled fron a DB and 2 of the <li> with
background color/image
specified in the CSS div
what i need is filling the lower item background to the same
height as
the taller one. is it possible with lists and CSS or should i
deal with
a table?
you can see what i mean here where the the first "column"
should have
the background color covering the row height:

i tried it and it works. but then every "row" has the same
height no
matter how long the content is. and what i need is them
adjusting its
height according to the content as it occurs in tables. or in
lists
without height (but with the problem that background colors
only cover

Hi，
Just switch to the start screen, then move the mouse to the right side, click the "Settings" bar, then click "Personalize", then choose a colour you want.
Add: you can also refer to this link to change the colour by editing registry

Portlet background color

I'm new to plumtree. The question I have is how can I change the default white background color of a page? I created portlet and add it into myPage. But the background color is white.

Hi, Mike.
It sure doesn't look like it from the administration tool! I will check
around and see if anyone has figured out how to do this!

Header background color does not work

Hi,
I would like to change the background color of the header element, but it does not work as I imagined
First of all, here is the HTML:
<body>
<div id="wraper">
<header>
    <h1><span>Pacific</span> Coastal Highway</h1>
    <nav>
      <ul>
        <li>Home</li>
        <li>Big Sur</li>
        <li>Pfeiffer Beach</li>
        <li>Elephant Seals</li>
        <li>Morro Bay</li>
      </ul>
    </nav>
</header>
// ... some other HTML elements & content ...
</body>
So, within <header> element we have <h1> and <nav> elements, and within that <nav> element there is a list that is actually menu.
Here it CSS code that refers to these elements:
#wraper {
    width: 1200px;

    margin-right: auto;
    margin-top: 0px;

body {
    margin: 0;

And, finally, here's how it looks:
Now, I'd like to change the background color of the <header> element (to chage that white behind that <h1> and menu into some other color), so I just added the background color of the <header> element in CSS:
header {
    background-color: #FF2D31;
But, here is how it looks now:
As you can see, although <nav> element with list (menu) is IN <header> element - the background color of <header> is just behind <h1> element.
Do you know why it's happening, and what would be the best way to solve this problem?
Thank you in advance.

The problem is caused when floated children do not force the parent element to clear the floats.

I'm trying to figure out what happened (and why) in my example, where the problem occurred, but...
I tried with inspecting elements with Firebug - to see what's what in case when there isn't overflow:hidden property that is related to <header> element in this example from the first post:
As you can see in the picture - <header> element is only that blue area containing <h1> element, and although <nav> element (with the <ul> element inside) is IN <header> element - it is not shown within the blue area, as it is not within <header> element.
As for the <h1> element which is inside of the <header> element, when I select it - it looks like this:
Now, purple area indicates the padding-top of <h1> element, and I guess that yellow area which indicates the margin is actually browser's default margin of the <h1> element.
Next, confusing is when I select <nav> element:
Although <nav> element is selected - there is no that blue area indicating where is that element on the web-page... ?
Next, when I select <ul> element, there is only yellow area indicating margin - I guess that yellow area which indicates the margin is actually browser's default margin of the <ul> element.
When I select <li> element - it's the same case as with <nav> element there is no that blue area indicating where is that element on the web-page... ?
Finally, when I select <a> element - it looks like this:
All in all - inspecting all <header> element and the elements within it didn't help me to see what and why this is happening (with the background color of the header element). I think the problem is in me, I'll wait a few days and maybe then things become clearer in my mind
Sorry for my bad English.
Again, thank you all!
