i've one imagefield. i want to show label field on that image filed.
How to show this on blackberry.
i expected like this image.
How to add label field with white background with fill 50%(for transparent effect).
if any sample code snippet. pls give.
Have a Field Manager, and override its width and height by methods sublayout method. and set image as background of this layout.
Now add a label field over this. and Set its background to some semi transparent color, by setting alpha.
Havent applied myself yet, but it should work.
I wouldn't provide any snippet. There are two possible solutions:
Use AbsoluteFieldManager put ImageField on it and put LabelField with transparent background and font color on the top (OS 5+)
Override paint in ImageField and after call super.paint() draw your text with transparent background.
The additional keywords for cases:
BackgroundFactory, Field.setBackground()
Graphics

I have a UILabel that whose background I want to set to black with alpha component so that this label can have a transparent black background.
In the storyboard when I set the background to the colour I want with an alpha component even the text of the label that is in white colour becomes lighter with the alpha component.
To overcome this problem I embedded the label in a UIView and even then the same problem persists.
How can I overcome this problem. Any help will be appreciated.
You can Do only With label make IBObject an write following line.
label.backgroundColor = UIColor.black.withAlphaComponent(0.4)
Instead of changing the alpha value, change the opacity of the label background color in storyboard.
For better understanding, I have taken an imageView and placed a label at the bottom of imageView and changed the background color of the label and textColor to white. At this stage you can't see the image behind the label.
Now, go to attributes inspector and select the label background color. There you can see the opacity and change it's value. Here I have made it 50%, you can change it to whatever you want between 0 to 100 until you get your desired transparency.
create the UIview with black background color and add the UIlabel inside the view and set the alpha to 0.5 of view . finally you get the black transparent, for e.g
if you need the label text in bold change the view hierarchy
place the UILabel fist then add the UIView.
Place the UILabelabove the UIView, not inside it.
Assume that we are talking about v1 the view that contains your label , if v1 is over another view that has bright colors then when your v1's alpha get lower your label white text color will become harder to see , the text color has nothing to do with the background alpha component , so you need to reconsider using the white color or the alpha component background or the view that is behind v1 make it darker that's all we can say
So, I was trying to mimic a video that uses sketch to design a login screen I really like. I had a question about how I can make a text field in Xcode look like the one that is being designed in the video.
Here is the video link: https://www.youtube.com/watch?v=gA_hFHkhqFM&t=87s
Here is a picture of the text field I want to design:
Any help is appreciated!
This is how to do it in the storyboard
Find/Create a blurry image and set it as an image view's image. Fill the view with the image view and add constraints. Add a new text field on top of the image view. Set these things:
border style to none
Text color to white
Background color to a black color with an alpha value and tint color to white as well.
This can be set by using the RGB slider in the color picker. Use the slider at the very bottom to adjust the alpha:
The easiest way to do it is to add a UIView with a black background. Set its alpha to 0.7.
Then add a UITextField on top. Set its border style to none, then the background color to clear.
You're done!
I have an iOS app that displays a CPTBarPlot. My plot bar responds to barTouchUpAtRecordIndex: by changing the background bar color but I also want to change the text label background and font color for that index. How can I change it?
The font color is part of the text style for the label. CPTTextLayer (the layer class used to display text in Core Plot) is a subclass of CPTBorderedLayer so it can have a border line and a fill behind the text. Set the padding to control how much of the fill is visible around the text.
I would like to chnage the background color.. At first i tried to creat a vertical container, but this did not work becouse the edges wrapped arounbd the content, so there was a big right and left margin.

You could set the screen background by:
Background myBG = BackgroundFactory.createSolidBackground(Color.RED);
getMainManager().setBackground(myBG);
can any one tell me how to set custom button field as background in black berry.
Thank you
You can't set a ButtonField as a background. If you are just trying to use an image check out the BackgroundFactory class. Also be aware that setting the background on a MainScreen typically doesn't work -- you'll have to set a background for a VerticalFieldManager and then add that to the Screen.
