I would like to cancel the zoom animation for the first element only. Is there any way to do it.
I initialise
ListRowPresenter(FocusHighlight.ZOOM_FACTOR_LARGE, false) like this
But the zoom animation applies to all the element in the row. Is there any way to not apply this zoom animation for a single content ?
I created two presenters and added zoom factor in one of the presenter on the focus listener.

I am trying to create a specific solution for weeks now and I have tried many things but I am just not sure if it is possible at all to achieve. I need your opinions and point me in direction o a correct approach. Following what I am trying to create:
Initially there is a tile layout in which a certain number of cards (say 12) are placed in 4x3 grid:
Now, if user clicks on a tile (Box 3), the state changes to following:
Selected tile is expanded and other tiles get aligned one below another on the right side:
Challenge is that I want to create a transition from every tile's initial state to the state where every tile is aligned one below another on the right. At the same time, when a tile is clicked it is expanded in place.
Note - there are no sudden change in positions, no reload of page and preferably no JS (I wanted to write a CSS-only solution). Everything smoothly animates to new position. From the second screen if a different tile is selected (from right), then the expanded item will shrink and go in to the right hand stack while the selected item will expand and take place of the currently expanded (B3).
If you could just point me to correct direction it would be great help.
thanks.
You should check css flexbox.
Using the "order" proprety, you could asign order of every box from 2 to 8,
and each time a box is selected, you change it's order to 1 and you also change its size and colour.
However, I don't think you can use 'click' actions with css only.
I would recommend using JS for what you are trying to achieve.
Hope it helps
I have an image that I show inside a canvas which I can zoom in on.
The problem is that when zoomed in, I try to drag the image, I can see the outline of the image in the foreground, (i.e.) outside the canvas boundary.
Is there anyway to tell the dragHandler to crop the "grabbed" image outside the canvas boundary?
In my experience using the built in drag/drop flex stuff is overkill for something that involves moving a component around in a canvas.
The easier way to do this (in my opinion) would be to listen for mouse down/up/move the image around in the canvas yourself.
When you detect a mouse down on your image, add a listener for mouse move (pro tip: make sure you set useCapture to true when calling addEventListener) and store the position of the mouse relative the origin of your image. Then whenever you get a mouse move, change the position of your image within your canvas taking into account the position of the mouse within the image (which you stored on mouse down). Keep doing this until mouse up occurs, then remove your mouse move listener.
There are some additional finer points to account for (what if the user drags outside of the canvas? Or outside of the browser window?), but this will get you started.
Hope that helps.
I want to introduce a canvas component by zooming from a height & width of 0.0 to 1.0. I want the component to be invisible until the zoom begins and then for it to be visible when it begins zooming.
However, if I bind the zoom effect to a showEffect trigger on the component and then make the component visible, it will first show the component at its regular size for a split second before it begins the zoom effect. If I combine the zoom effect and setting the component visible together in a parallel, it will also flash the component at its regular size for a split second before the zoom. If I make the component visible when the zoom effect starts through its effectStart event, it still does it. Does anyone know how to make it visible only when the zoom effect begins so that it doesn't flash the component at its regular size for a split second before the zoom effect?
It'd be easier to provide suggestions if you were giving us code.
That said, the reason the component "Flashes" at full size before the effect starts probably relates to the positioning and sizing of the component before the effect starts. So, before you start the effect just set the height and width of the component to the zoomHeightFrom and zoomWidthFrom of the effect.
These things can be tricky to debug, though. Especially without code.
Found an easy solution: Put the zoom effect and set property action, which sets the component to visible, in a Parallel together but add a nominal start delay of 50 ms to the set property action.
I'm doing an application in flex where I draw different sprites inside a canvas. Depending of the dimensions, scrollbars can be appear. I would like to move the "image" with the movement of the mouse as you can see at the Adobe Reader when you are reading a document with zoom (hand mouse icon). In this way, you dont have to touch the scrollbar.
I'm start trying with drag and drop properties of the canvas, setting the position of the scrollbar according with the movement of the mouse but that is not as I expect.
Any ideas or suggestions?
Thanks in advance.
Recipe:
Listen for the mouseMove (MouseEvent.MOUSE_MOVE) event on the canvas
In event listener, examine event.localX, event.localY
Based on those values and the canvas's width and height, set the canvas's horizontalScrollPosition and verticalScrollPosition accordingly
Hope this helps.
What you can do is, change the position of the scrollbar , when the mouse reaches the last 20 pixels on the left or the right, or the top and bottom.
What you would really need to do is, have a mouseMove listener on the whole application, and when the mouse is within the end ranges of any of the sides, you can use the scroll.scrollTo function to move the scrollbars.
I'm aware of PopUpManager and that custom modal windows can be created.
But let's say I have a simple Canvas(or any component) and when I show it the background needs to be blurred out like how PopUpManager does when a new pop-up is shown.
Is this possible?
Not without a lot of work. The PopupManager puts a blur on Application, and then puts the popup in front of the Application, but as a child of the SystemManager, so it's a sibling to the Application in the display list rather than a child. You could take a screen shot of the Application, run a blur filter over it, and place it as the last child of Application, and then place your component on top of that, but if you do that you might as well just use PopupManager in the first place.
I think the blurring has to do with how you set the alpha level on the component.
