How to make a black background for a horizontalFieldManager?

I have a custom HorizontalFieldManager that bears a label for the field. I want the background of the black horizontalField Manager. How can I do?

Please help me...

Unless you develop only for 4.6 + devices, setBackground won't help you (this set appeared in 4.6.0).

The cleanest way will be

protected void paintBackground(Graphics g) {
  int prevBgColor = g.getBackgroundColor();
  g.setBackgroundColor(Color.BLACK);
  g.clear();
  g.setBackgroundcolor(prevBgColor);
}

However, you also want to ensure that the text on your LabelField is visible, as prash_bb_dev pointed out.  Either have the LabelField use, say, white background (same solution in a different place, replace Color.BLACK with Color.WHITE ) or indeed set white color inside of object and call the super.paint ().

  • Tips on how to make a business case for partitioning

    Hello world

    I am the architect of a team of business intelligence/data warehouse. We have grown to the point where I think that we need database partitioning. I believe that we are at approximately 1.5 TB of data. Our larger tables are the counts of 100 million lines with relatively large lengths Records (~ 100 columns). Our just a sort of large tables are of the order of 10 million to 50 million, however, they have very long line lengths (~ 300 columns). Based on the plans of our future source system, our data will become even more granular, and it is always necessary to maintain our historical data.

    Those who are not the only reasons, but are some conduct issues that make most of our team members think it's time we purchased database partitioning. Our team is fairly unanimous for partitioning, many of our partners from the source system also deem an 'evidence', however, we get a push back of our CIO saying that 1.5 TB and 100 million records is not only the large amount of data compared to other 'big Data' businesses and that it requires no partitioning.

    Anyone has any advice on how to make a business case for the purchase of partitioning? Is there a good way to demonstrate the value of profitability-vs?

    Thanks for your comments.

    The best cost c. analysis of benefits is that you put together based on points regardless of the pain you feel.

    For example, you have pain around your evening of meeting load ALS? If you do, you can watch how (and if) partitioning would allow you to streamline your loading process and how much time you would save probably every night. If you have no problem hitting your evening load ALS today, however, this probably isn't something you want to focus on.

    You have pain around query response time? If Yes, you can watch how (and if) partitioning would improve some of the queries and most important reports. Or, perhaps, he would have you to allow users to do an ad hoc analysis more than you can't afford today because the cost would be prohibitive.

    Although you will find no doubt generic cost v. benefit whitepapers, it tends to make a much better case if you focus on what causes the pain of the company and what you as the application developers are willing to commit to. It is easy for a CIO watch a generic white paper saying "partitioning reduces ETL time up to 99%" and the question of what improvements he or she would have actually see and how this is marketing hype. It is much more difficult to look at a document put in place by the data warehouse team saying "partitioning would allow us to reduce the load of X of Y hours on Z hours every night. "That would allow us to hit our SLA w % more often without adding hardware / additional treatment for A project that we have been postpone / let Department B start to work with the data more early every morning / what causes the pain of the IOC. Of course, this means that he must be willing to make such commitments (and, of course, to meet).

  • How can I remove a black background for iMovie version 10.1.1

    I realize you can remove backgrounds, green, and blue, but can someone please tell me how I can remove a black background on the images.

    If you are referring to the use of the utility screen green/blue, green, and blue are the colors of background, only that you can use in iMovie.  To have a wider range of background color options, you must use a professional video editor such as Final Cut Pro.

  • Black background for Google

    Hi, you all! Since I have updated at 12.10, when using Firefox, I get a black/brown background for Google. I would like to know how to return to the classic Google homepage. Thank you!

    You use code in userContent.css or extensions like Stylish?

    It is possible that an extension of Ubuntu is the cause.

    Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox/tools > Modules > appearance).

    • Do NOT click on the reset button on the start safe mode window or make changes.

If you have a clip of fire without an alpha chanel on a black background you can use the screen blend mode add or download the red giant Unmult plugin. It's free. Unmult works only with 100% black origins.

  • How to make a recovery CD for Windows Vista Home Basic?

    A friend recently gave me a laptop Acer 5315 to play with (I like to play with the old pc...). It came with Win/Vista Basic Home Edition. I got to level with SP2 and 2, kicking the 2gig memory (this is the limit) and now I want to create a backup/recovery disk. It has a CD inside player, but is limited to CD (not DVD). I've been looking around, but apparently creating a Vista recovery disc without the original install disks is not easy. It's true.

    Anyone have any ideas?

    Hello

    Strange that it is limited to the CDs, Vista came on a DVD, unless you have specifically ordered CD from Microsoft if you had a license to retail not OEM...
