How to add navigation keys to tview? - go

In my app, I want to change focus between my lists based on short keys. The demo gif shows it at the bottom, but I can't find any reference to it in the API. I can implement a SetInputCapture function on the Application instance, but it doesn't show the user the keys. Is there any way to do it?

App inventor duplicate button with pressing a button

How to program a button which actually just should create another button with the same function like another existing one?
screenshot
I want to add another Button with the same Funktion like the one on the top on the left side.
I know, it would be possible to just add several another buttons and switching visible to true and false, but that would mean that I had to add the elements manually and the number of these buttons would be limited which I would try to avoid.
You could do this using an extension...
You might want to look into the Dynamic Component Extension by Appybuilder

How to implement a threaded view?

I need to implement a threaded view of sorts in an old VB6 app. It should look similar to this:
So, it's like a TreeView of sorts but there are buttons on the right (for each row) that could be pressed. The view does not need to collapse - it always stays in the expanded mode. The users should be able to respond to each node (via the comment button on the far right). And, of course, users should be able to scroll through the entries.
What are some of the ways I could implement this? I am open to 3rd party controls, paid or not.
VSFlexGrid has an outline mode. You can set the indent per row via the RowOutlineLevel property. It supports word wrap, images, etc within its cells/columns so you should be able to get pretty close to what you want. It also supports owner-drawn which lets you fully customize the cell painting (for example, to get those rounded corners).
I'm sure there are other controls out there as well...

Xcode Need guidelines on invented draft for photo gallery manager

For this question, I don't require a full explanation of all code, but helping me get insight into the process for achieving this result would be very helpful! Some information sources that will lead me to where I want to be.
Don't hesitate to give your opinion or make suggestions on how you would make it better in case you have better ideas - We just want to jump off the regular photo album system.
In the added screenshot I have added a painted image that makes the purpose clear.
Albums are created by tapping the "+" sign. (This shows a popup window in which the user can tag a bar/event to which the picture applies; the bar/event profile picture will appear on the album cover).
Newly taken pictures should appear in a separate band on the screen. They will float there until the user drags and drops them into an album. Note that the picture is also taken from within the app (using the native camera of the smartphone).
When the user added them to an album that was tagged, they will also be displayed automatically in the gallery of the tagged bar/event profile. (Of course in the app, personal profiles will be available as well).
Which technologies / workflow would you advise me?
What I need to create now is just an empty shell for the app that demonstrates the visual workflow (the data flows are not important at this point).
I have read about some libraries such as three20 or UIImagePicker, I don't know if they are easy to customize towards our needs.
Thanks!
I cannot comment on the likes of Three20 as I have never actually used them.
One method I can suggest, is using a number of scrollviews. Based on your example, you would require 2 individual scrollviews. (For ease lets call them AlbumsSV and PicturesSV).
The AlbumsSV would dynamically load content, based on your backing store. One approach I have used in the past, is to load custom views into a scroll view, as this allows for maximum control, you can specify any requirements as properties of the view (i.e Primary key etc), also you can load a 'preview image' based on the data held in your data store.
Assuming you always want the ability to add new items to be last element added to the AlbumsSV, then you can simply add another custom view to the AlbumsSV after all other items have processed.
PicturesSV would simply load content based upon what is in the users camera roll. Again I would recommend using a custom view, as you can set properties such as FileURL etc on the custom view, this will aid when it comes to dragging items into a specific album.
Hope this helps :)

slide-in search box on windows phone (like in the bing maps app)

In the bing maps app on windows phone, when I click the search button I get a search box sliding in from the top of the screen, and the keyboard sliding in from the bottom. I want to achieve the same behaviour in my own windows phone app (based around a bing map control).
I will want a few drop-in boxes, such as for setting up a filter (which will need a few check boxes and text entry), and adding an item (which will require a text entry for the name, and ideally still allow the map in the main panel to be panned to fine-tune the location of the item).
I'm pretty sure the keyboard comes up automatically when a textbox gets focus, but I'm not sure what might be the best approach for dropping in the search box. It looks like it would need something with storyboards/animations/projections, but I haven't found a clear standard approach so far, and I want to make sure I do it the right way from the start (as I don't really have time to do it twice).
Is there a standard/best practice way to achieve the effect?
Yes, and you don't need a single line of code. You can express the whole animation using XAML. Get a text on Silverlight and read the chapters on animation with particular reference to storyboards and Easing.

Create multiple page form in Cocoa

I want to create a form with iOS like transitions (in a Cocoa desktop application) between the form input. For instance, the user would input information to the form and click next to continue to input the remainder of the information. On the last form, the user would click submit. Upon clicking next, the form would have an animated transition, like on the iPhone before displaying the next set of forms. Sort of like how Turbo Tax ask a ton of questions before allowing you to submit that grouped information.
What would be the best approach to achieve this goal?
This is commonly referred to as a wizard.
You basically have two options:
Use a tabless tab view, following Apple's sample code in AnimatingTabView from http://developer.apple.com/library/mac/#samplecode/Reducer/Introduction/Intro.html
Manually swap the views in and out yourself.
There are pros and cons to both approaches. Which you choose will probably depend on your requirements. One issue with Core Animation on the desktop is lack of subpixel rendering for layer-backed views. This is mostly an issue with text display but some people find it not to be an issue.
I've needed this functionality a few times. I used this tutorial to get started.
