How can I set the foreground/background color after using CSPickColor()?

Hello all,
Is there any one who has experience on changing foreground or background color using Photoshop Plug-in SDK?
Currently I can get a returned color from CSPickColor(), but have no idea how to use it.
Thanks!

You can try a linear-gradient that starts at gray 0% and ends at white <whatever the percentage the thumb is at>.
        final Node track = slider.lookup(".track");
        slider.valueProperty().addListener(new ChangeListener<Number>() {
            public void changed(ObservableValue<? extends Number> ov, Number t, Number t1) {
                double pct = (t1.doubleValue()-slider.getMin())/(slider.getMax()-slider.getMin())*100;
                track.setStyle("-fx-background-color: linear-gradient(to right, gray, gray " + pct + "%, white" + pct + "%, white);");
        });Edited by: dgrieve on Apr 12, 2012 12:19 PM

How can I get the foreground/background swatches in my panel?

Howdy all-
Been loving this forum, it's been extremely helpful getting started with Configurator. I'm pulling together a panel for my students to guide their retouching work and the last thing I am trying to get in is the foreground/background swatches like at the bottom of the toolbar. Is this possible? I haven't found it in the provided libraries- is it something that would need a script or am I looking in the wrong places?
thanks so much again for the forum and any help anyone can provide.

Hi
You can only switch foreground/background color or set them to default color
As in the previous thread ( by ipf55 )
you have the possibility to insert the color picker.
so the workaround is :
switch to foreground ( or background as you prefer)
choose a color with the color picker button (Now the foreground is set with the color you choosed)
then repeat te step for the background
to choose a color you could also ( e.g.) insert into your panel a button that open the swatches panel

How can I set the date of my PC using Java?

Which class has the function to set system date and time.
Thanks in advance.

but the following sentence
Process p=Runtime.getRuntime().exec("date
11-03-2002");
always throw IOExecption error
java.io.IOException: CreatePreocess:date 11-03-2002
error=0
and why?
How to settle it?
'date' is an internal command which means you need a shell to run it. Depending on the OS this will either be 'cmd' or 'command'. If you search the forums with the following keywords you will find examples on how to use this: "exec", "Runtime", "cmd" or "command"

How can I create an alt background color for items in a jlistbox or jtree

          list.setCellRenderer( new MyCellRenderer() );
          JScrollPane scrollPane = new JScrollPane( list );
          getContentPane().add( scrollPane );

               if (!isSelected)
                    setBackground(index % 2 == 0 ? list.getBackground() : Color.LIGHT_GRAY);
               return this;
}

How can i set the alternating colors for a table rows

Dear All,
Please any one help me how can i set the Alternating colors for Table Rows.
i created a theam there i set the background alternating color to brown and i set the table design properity to alternating. but it is not reflecting.

Hi,
The design property in Table properties should work for your requirement. Select "alternating" value for design.
Please see the API below:
design
Determines the appearance of the table. The property design can take the following values and is represented by enumeration type WDTableDesign.
alternating - The table rows are displayed alternately in a different color.
standard - The table background has one color. The individual table rows are displayed with grid net lines.
transparent - The table background is transparent. The individual table rows are displayed without grid net lines.
Check whether you have changed the right property or not? Also table should contain more than one rows to test this scenario.
Regards,
Jaya.

Hi,
Try saving your settings as a Preset by clicking the Preset drop down and then select Save Current Settings as a Preset.
Next try changing the settings by selecting the saved preset.
That allow saving the settings for a specific printer, I assume it may also allow selecting these settings for another printer.

How can I disable the change of color when changing background in ios7?

how can I disable the change of color when changing background in ios7?

For txt messages you can change the option of whether previews are shown (Settings >> Messages >> Show Preview Toggle). Switching this "Off" will still show a notification of a missed txt message, but it will not show text from the message itself.
Unfortunately, similar functionality does not currently exist for phone calls; however, the new iOS release (scheduled for September, I think rumor has it) will revamp the way notifications are handled, and there maybe an elegant solution for you then.

How do I change the tab background color in Firefox 4?

I just upgraded to Firefox 4. Tabs are now fine black font on dark grey background -- very hard to read. How do I change the tab background color?
I have searched and the closest I can come is some instructions for modifying .css files, and it is not clear that those instructions will impact the tab background color.
Thanks in advance for your help.

Similar question asked by TH received another response.
Here is the address of that question and answer:
https://support.mozilla.com/en-US/questions/804464?s=change+tab+color+firefox+4&as=s
I like the solution recommended there.
Added information - after several days experience, I notice that some tabs occasionally revert to the original dark grey. So I am still looking for a better solution, ideally within Firefox rather than via add on. This seems like a basic setting for the browser that should be easy to change, rather than something so complex that I need an add on to change it. Or just build it without such a dark grey background to begin with and I would not need to change it.

Yes you can do so in the Bridge preferences under general both Ui interface and image backdrop can be changed
In the same preferences Cache you can change the location of the central cache to where ever you will. But you have to realize that if you use an external disk this can cause all kinds of problems regarding speed, performance and permission issues. best to keep it on an internal disk and having an SSD available will be even better because you will benefit from performance and speed very much.
it's gray , may i change it?
As long as you have a legal version and it is able to change then feel free to set it to your own custom wishes...

An app changed it to some other search engine, before installing the app, I the tab that would open was the homepage I set.
In my case it is Google, and I want my new tabs to open on Google like they did before the installation.
thank you,

You can middle-click or Ctrl left-click the Home button on the Navigation toolbar to open the Home page in a new tab.

Thanks for any suggestions

How can I set up an older airport express using the newest airport utilities?
Unfortunately you can't, since Apple dropped support of the older AirPorts with AirPort Utility 6.x.
Using some workarounds....not supported by Apple.....you might be able to download and install an older version of AirPort Utility that would allow you to administer the older AirPort.
