I'm working on a Flex 4 application and I started customizing the interface with skins to give a whole new look.
So, I've created two scrollbar skins in Flash Catalyst (one horizontal, one vertical).
Its working great when I test the application through Catalyst so I took it and imported it on Flash Builder, copied the components and defined the new skins in my css file for the HScrollbar and VScrollbar.
The skin is working, all the buttons are ok. But, the scrollbar isnt resizing for some reason. It remains in the same height I've designed it to be regardless of the content it is bound to.
It scrolls the content in all the ways it should be but it doesnt resize and the thumb isnt getting all the way down.
Also I've noticed the following.
I have a custom component acting as a list. It extends Group and contains a Scroller. So at one place of the application the Scrollthumb is getting lower than on another place where the same custom list is used.
I also have to mention that this scroller works perfectly without a custom skin.
Anyone else having similar problems?
Okay, I know you posted this a while ago but I have been scouring the internet for days looking for why the scrollbar's thumb wasn't scaling like the default scrollbar.
There are a couple things to check, first is there a set height on your thumb's skin?
If not, and this is what I was overlooking, go to your scroller skin and at the point where you add the vertical and horizontal scrollbar set the "fixedThumbSize" property to false.
I suppose that your graphic elements are defined as every single part of the scrollbar (top arrow, bottom arrow, track, etc...): in this case you should check that the elements dimensions are not fixed... they should be in % to be able to change the dimensions based on the container.

I'm trying to make an application that looks like the Messages app from Apple.
The NSSplitView has toolbars on both subviews of the NSSplitView. They blend in with the top toolbar. It's similar to the NSToolBar but that doesn't work in NSSplitView's. Is there any way to make this work?
I tried the CNSplitView but it doesn't provide the proper effect. Is there another way of doing this that I'm missing?
The interface i'm going for is here:
Instead of using NSToolbar, you can add your own views to the top of subviews in the NSSplitView to achieve this after hiding the existing titlebar.
NSWindow's titleVisibility can be used to hide the built-in titlebar, and by setting the window's styleMask to include NSFullSizeContentViewWindowMask you can cause the split view to take up the full height of the window.
To get the blur effect like toolbars/Messages you can use NSVisualEffectView in the top views. Setting the material NSVisualEffectMaterialTitlebar will give the same look as standard titlebars.
And finally, you can put NSStackViews inside the visual effect views, and then place the titlebar controls in there.
(And depending on the content that is below your fake toolbars, you might want to look into NSScrollView's contentInsets property to allow the scroll view to show all of the content, but still be able to scroll under your toolbar).
Is there a way to adjust the thickness of the scrollbars of a WebView using the stylesheet used by the whole JavaFX application?
I am a bit confused since
on the one hand I read that the scrollbars are not part of the JavaFX UI control and therefore can only be customized by a stylesheet set on the web engine (webview.getEngine().setUserStyleSheetLocation(..)) which means I have to write another CSS trying that the scrollbars look like all other scrollbars in the application
and on the other hand I can see that the scrollbars are obviously correctly customized using the JavaFX CSS except the thickness of the scrollbars (and that the vertical scrollbar is always shown even if the loaded page requires no scrollbars at all)
So where am I wrong and which is the correct way to solve this problem?
Thanks in advance!
I'm developing a application which has a ListView which contains items which needs complex cell layouts. The cells are in variable heights and some of the cells tends to be larger than the view port height.
But when the ListView is filled with items the scroll thumb tends to resize its self while scrolling, which makes it hard to hold onto the thumb while scrolling. This happens mainly when passing through different size of cells.
This is not a problem in Swing if I create a same kind of a cell render to be used with the JList. This problem is there in JavaFX 2 and JavaFX8 both.
When looking at the VirtualFlow which is responsible for layout of the ListView and handle scrolling, it seems that the scrollbar thumb side (lenghtbar) is calculated based on the cell count and the visible cell count, which is actually a problem when it comes to lists which has variable heights of cells.
So is this the future of the scroll bar behavior for Java FX list views? or is there any solution available for this problem? Or should I try to hide the scrollbar and provide a different user interaction to scroll?
This problem is already reported under https://javafx-jira.kenai.com/browse/RT-25059 and fixed in Java8 upto some extend. So if this fix is needed on JavaFx2 we have to backport the changes under commit http://hg.openjdk.java.net/openjfx/8/controls/rt/rev/81cc13fe6f96
To get this changes in JavaFX 2.2 you need to apply the required changes on to FX2.2 VirtualFlow.java class and load those changes before the jfxrt.jar is loaded. Another approach is if you don't like to mess up with the jfxrt classes is to have you own ListView which uses your own Skin and the patched VirtualFlow version may be with a different name. But this might require lot of customization compared to first solution.
More approaches are welcome :).
I am building this form: http://codepen.io/anon/pen/gFoIG/
and so far I am satisfied. Unfortunately I have some issue that I seem not able to fix.
First of all, I want to enforce the label positions beside their respective inputs. Now the form breaks down easily (with the opera emulator for smartphone and tablet, the privacy label goes below the check, but I want that it stays beside it)
The other issue that I have is that I want it to fall back gracefully when there are small screens, like placing the second image below the first and placing the input controls one below the other and take the full screen width to be bigger and easier to interact with, but so far I only was able to break the layout with my tests.
This issue: the the form layout breaks, the internal control (input, button, etc) go outside the container div. How do I enforce the container to keep everything inside? I've experimented with blocks, floats and whatever, but if the layout breaks, the input boxes usually go outside the gray rectangle.
Last issue: If I insert this form inside an existing website (for example, a page in wordpress) the layout get completely destroyed because influences from the theme style. How do I enforce my style on my form, keeping it isolated from the other styles? I can think of the iframe as a solution, but it is the only one? It is a good practice?
Anyone can help me with that?
You might want to take a look here. Its a site I just set up to explain an approach to responsive using a jQuery plugin to manage redoing layout. I think it could work for your example quite easily. Also because it can target a container div at any depth in a web page, it could be helpful in the scenario where the layout you want to reflow is inside a 3rd party container (as long as you can run script on the page).
Please help me what container component I will use. Here is my problem, I have advance data grid with full of data about 300 by 300 row-column(data can be picture). Now I need a container that can zoom in/out, fit to screen capability and can drag around the component inside so that my data grid will be zoomable and dragable around the container(Easy for the user to read content inside my datagrid). Any suggestion for a container that fits on what I need. Thanks
You'll likely have to add some functionality to AdvandedDataGrid to do that sort of stuff. The grid only renders cells that are currently on screen (well, mostly) to achieve a decent performance level. If you enlarged your grid to show all cells and then embedded that into a container that managed scrolling, etc, it would likely be unacceptably slow.
But you could add event handlers directly to the grid to manage your new user gestures.

Maybe the dragscrollCanvas container, combined with scaleX/scaleY events on the datagrid in response to mousewheeel events for the zoom?
Not sure exactly what you need...
you need to use a custom itemRenderer for your datagrid field. There are some great tutorials out there...
http://www.adobe.com/devnet/flex/quickstart/using_item_renderers/
http://www.adobe.com/devnet/flex/articles/itemrenderers_pt1.html (is a series of
And if you know what you are looking for then I'm sure that you can find the right itemRenderer for your datagrid.
Then using your custom component you can move it around, zoom, etc.
If you are talking about the container that contains the datagrid checkout the flexlib mdi container. This container can have other windows inside of it then you can tile, cascade, fill, etc. This also supports dragging.
