How to show field details which field is on center position? - blackberry

I have a set of fields on a horizontal scroll bar. My questions are:
When I scroll the fields and display the details in another layout. Which field is on center position?
How to move a field at center position when I click the field?
Please help me. Any ideas, links or sample code are appreciated.

What you are describing sounds like CentricHManager described here

swift 4 and Xcode autoLayout and UIImageview as Button

I am working on auto layout and making those UIIMages as Button.
I would like to make those button to be clicked and switch the images
as well as showing some words in the label.
In this case what should I do?
In addition, as it is shown, the auto layout ratio is different only from the iPhone SE. In. this case What should I consider?
Many thanks,
The first thing you need to learn is auto layout. Start with basic Always go with Apple's doc first
This one I likes he is good and you will also find how to use buttons as image view, using card game example, check other tutorials also very helpfull.

As far, your question just gives your label Horizontal in the container constraints(open storyboard in the right bottom third from last (allin) click on it popUp will open), and 20 bottom to the buttons and it will be in the centre. Every elements need x,y height and width so it knows exactly where to place, so you also need to give constraints to the buttons, Learn stackView to understand how to place your button without giving many constraints to each button and stack view will handle it for you, try hide and show to one of the button and magically stack view will adjust all adjustment. I suggest before staring Do read apple's doc first.
And Your question is too broad to answer, so read and try adding different constraints based on your need and ask a specific question(after trying by yourself) like why this label getting cut what constraints should i add so people know exactly what you want to achieve, people are always ready to help, just ask the right question.

Centering a checkbox without a caption inside a TGridPanel

Searched all over Google and I'm afraid I can't find an answer to this.
Here is my current situation:
Instead of having those checkbox aligned to the left I want them centered like so (photoshopped obviously):
Anybody know how to achieve this with VCL? Thanks.
Edit:
These components are inside a TGridPanel and for whatever reason the Left and Top properties have no effect on the position of the component in the cell. I have also looked for any layout properties with no luck.
The controls inside the TGridPanel are automatically center-aligned. If you reduce the width of the checkboxes to the correct value it should be centered as requested. Be aware that if you reduce the size too much the checkbox will shrink.
I managed to find a solution although it's rather messy. But for future reference I had to create a panel for every single cell in my GridPanel then that allowed me to set the left padding property of the panel to push my TCheckboxes over.
Yes it's super inefficient but it's the best I've got so far. Also fixes my issue of wanting to show the cell outlines inside the GridPanel.

How can I style a text field in iOS (Swift)?

I am a beginner and just started learning iOS. I want to achieve this layout, using Swift:
When you drag a text field into your project, there's a number of styling options available in the Utilities bar in Xcode, that can help you style the shape, colour and other properties of your field. To achieve the look you want, you could use something like this:
Place a UITextField and a UIButton on your story board. Then select both items, and then go to Editor, Embed In, stack view. If they are one on top of the other, change the stack view orientation to vertical then they will be side by side as shown above. Next change the attributes of both in the attributes inspector to taste. You can change the attributes manually in code using textField.defaultTextAttrubutes = [ "the look you are going for"], but you should need to in order to recreate your example.
you can add a view container to your view, inside that container .. add a button and a textfield then add positioning constraints on them.
as you can see in the picture .. it illustrates the idea .. you can style it the way you want e.g. change the height of your textfield .. change its border style etc. the same with your button.
example
In order to add a border, you have to enter some specific information in the attributes inspector. Here is a snapshot of what you can use to create border radius if you want one, vary the thickness of the border, and select a color for the border. screenshot of attributes inspectorYou can vary the values to make the radius greater and the width thicker also, plus you can change the color. Pay very close attention to the spelling otherwise this won't work.

There's some decent options out there for wrapping the content in your UIScrollView. Check out: Make UIScrollView wrap around.

Use HorizontalFieldManager and add the contents in it
It will work
Use Manager.HORIZONTAL_SCROLL as argument in it
eg:
HorizontalFieldManager hfm=new HorizontalFieldManager(Manager.HORIZONTAL_SCROLL);
This BlackBerry support forum thread will help you, in addition to the PictureScrollField documentation.
