I am no expert in Flash, and I need some quick help here, without needing to learn everything from scratch.
Short story, I have to make a list where each cell contains an image, two labels, and a button.
List/Cell example:
img - label - label - button
img - label - label - button
As a Java-programmer, I have tried to quicly learn the syntax and visualness of Flash and AS3, but with no luck so far.
I have fairly understood the basics of movie clips etc.
I saw a tutorial on how to add a list, and add some text to it. So I dragged in a list, and in the code went list.addItem({label:"hello"}); , and that worked ofc. So i thought if I double-clicked the MC of the list, i would get to tweak some things. In there I have been wandering around different halls of cell-renderers etc.
I have now come to the point that I entered the CellRenderer_skinUp or something, and customized it to my liking. When this was done, I expected i could use list.addItem(); and get an empty "version" of my cell, with the img, labels and the button. But AS3 expects an input in addItem. From my object-oriented view, I am thinking that i have to create an object of the cell i have made, but i have no luck reaching it.. I tried to go
var test:CellRenderer = list.listItem;
list.addItem(test);
..But with no luck.
This is just for funsies, but I really want to make this work, however not so much that I am willing to read up on ALOT of Flash and AS3. I felt that I was closing in on the prize, but the compiler expected a semicolon after the variable (list.addItem({test:something});).
Note: If possible, I do NOT want this:
list.addItem({image:"src",label:"text",label"text",button:"text"});
Well.. It actually is what I want, but I would really like to custom-draw everything.
Does anyone get what I am trying to do, and has any answers for me? Am I approaching this the wrong way? I have searched the interwebs for custom list-cells, but with no luck.
Please, any guiding here is appreciated!

You could use a Datagrid as well, with each column pointing to the appropriate part of the data source (possibly even the same field, depending on what you're doing). You can then just use the ImageCell as the renderer for the second and third colums.
I think you're just not understanding that Adobe, in the own woolly-headed little way, is separating the Model from the View on your behalf. You hand the Model to the View and then get out of the way. The extent of what you can/should change is just telling it what renderer to pop your data into.
In fact, the fl.controls don't give you much control at all about how they work--I wouldn't go down the road of trying to create a custom itemRenderer with any signifcant functionality for them if you don't fully understand how the Display List works and if you're not comfortable digging around in the debugger and ferreting out all kinds of undocumented information.
For more details (to the extent anyone knows anything about how these work), see

Do you have the option to use the Flex Framework instead of pure Flash? It makes this kind of extension much more satisfying. It's aimed more at application developers, whereas Adobe sees Flash users more as designers.

It's even written in the doc that Camera.unproject() assumes that the screen has it'origin in the top left corner, on the other hand Camera.project() assumes that the screen has its origin in the bottom left corner. This is so annoying. Is this intentional? Am I not getting something?
tmp3.x = selected.pos.x;
tmp3.y = selected.pos.y;
camera.unproject(tmp3);
camera.project(tmp3);
This flips the vector, where it should return the same vector.
EDIT:
First I was trying to use Viewport.project() and Viewport.unproject() to convert points from one viewport to another (to position a context menu over a game element).They also inherit this naming confusion, and it's not even mentioned in the javadocs there.
PS. I really like libGdx. I've just written this to maybe spare some headache for someone in the future as I didn't find this anywhere on the web pointed out directly.
The Javadoc for the project method explains why. I think the assumption is that the most common reason to project a point is to line something up with the UI which will also be Y-up. But when I projecting, it is most likely to convert a touch coordinate to world coordinates.
Or in another way of looking at it, everything you do in OpenGL is Y-up so everything's designed to be Y-up or to get you there.
Not saying this is necessarily the best way; just trying to guess at the thought process. It probably wouldn't hurt to submit a PR for another type of project method of you need one, or you could subclass whichever type of camera you're using and add the additional method.
first post on here so be gentle!
I am currently designing an ad banner for my college assignment, the main feature i have is a car spinning, like a full 360 degree view.
Now I have took all of the media I needed and photoshopped them to how they need to look I just need some diction of where to go next.
I did want it where you can click and drag anywhere on the screen and it pulls the car around to where you want it, but I don't even know where to start with that! (please help if you can)
So I thought I would instead have it as a sort of image gallery with a next and previous button to select the next frame you want. But I don't like the way it looks so I was wondering if there was a way with action script where I could click on a button(next/previous) and the car would spin until I un-click? Rather than me having to keep clicking to load the next frame.
Also if I could I wanted a left to right scroll bar what could control the images, do you know any way of doing that?
Many Thanks in advance for ANY help!

If you want a commercial solution:
Krpano -> very advanced, excellent support, highly recommended for panoramas, 2D object is a bit lacking tho. Examples of 2D object
Object2VR -> very easy to use, not that great support, lacking API.
I would go personally for krpano because it is simply a superior tool. Great for panos, tons of possibilities. If you want it easy, go for Object2VR.
Now if you want to program it, and you need to program it, there are many options how you can do it. First of all, you need to load all the images into your app. Even if you don't maintain them in memory (that would be prefered, tho), you should load them so they are cached and can be reloaded fast. Your rotation can be achieved by "re-loading" the next image, or if you keep them in memory by simply referencing the next index of the array/vector. You always keep a reference index and upon click you simple increase the index and load the image. You than swap the images. It is too broad to explain, you will simply have to begin and ask for advice with some specific code.
There's probably a million posts about scrolling in AS3, but the problem I'm having is quite different. I have no problem making scrollbars work (have done loads of times), but I'm having a problem with custom skins. I'm basically trying to make the bar in this concept:
concept http://img842.imageshack.us/img842/5081/screenshot20130507at140.png
The key part is the thumb. When customising the skins in Flash, it scales the thumb bar (which hasn't been a problem in my previous projects, but in this one I want to have a non-scaled graphic like the one in the concept.
I've done a few searches and apparently this isn't easily achieved (something about extending the component class that I didn't really understand), but I find the UIScrollBar very easy to use. So my questions are:
Is there anyway to get UIScrollBar to do what I want?
Failing that, is there a third party equivlent of UIScrollBar that'll do what I want?
Failing those, what is the most pain-free way of making a custom scrollbar in AS3? (I realise there's a lot of tutorials for this out there, but there's too many, so if someone could point me towards a tutorial that doesn't require cause pain I'd appreciate it)
Thanks! (:
I am writing a custom application in C using GTK+2.0 and Cairo. Just for learning purposes (and if successful, then for deployment), I wish to recreate something similar to a overlay toolbar/widget (I am sorry if the terminology is not correct) that appears when a mouse moves over a given area on the window, and disappears when the mouse moves away. The toolbar, as I imagine, should appear on top of the existing widgets without displacing them or altering the widget packing in any way. Is it possible to accomplish? If yes, can you please point me to relevant tutorials/examples and/or outline a way to do the same?
Thanks in advance.
Not sure this is easily doable in GTK2. However, I learned recently that there's the GtkLayout widget which allows pixel exact rendering of widgets, so you can even display some widgets over others. Or you may implement your own container widget.
Please note that since GTK3, there's GtkOverlay which seem to do what you want.
You may also give a look to Clutter, which might allow this. Furthermore, there are projects of merging GTK and Clutter for GTK 4.
The little known GtkHandleBox is capable of doing what you want. I must warn you it is deprecated in GTK+3 because is going against the usual UI direction. Also, the correct positioning will be subject to the windows manager quirks, so I'd expect some issue in this regard.
I am a flash developer who has worked mostly on small ActionScript projects, in particular websites, but I am dipping my toes into image manipulation with AS3. I have a project I'm working on to develop an application which would allow a user to upload their own picture into a swf, and then, using a slider, they can alter the image to make themselves look thinner or fatter. The condition is that it should require minimal user input - so ideally the most I could expect from the user would be a couple of control points identifying certain areas of the face in response to prompts e.g. 'click on the centre of the chin' and when the user clicks, the position would be stored, but this would need to be used sparingly, if at all.
So far, I have been able to use the FileReference class to handle the upload, and I am experimenting with using the DisplacementMap filter to edit certain parts of the uploaded image, but I am having serious trouble implementing this in a manner that would allow realistic deformation of the facial features in the image uploaded.
Is there anything that exists that might run along the same lines and that provides an explanation/source code I could look at to get a better idea of how to go around doing this? Or if there are any other ideas on how to manipulate and distort the image that doesn't use the DisplacementMap Filter?
Any feedback and help is greatly appreciated. Thank you for your time.
