It’s time for another ControlsFX release, this time taking the version number to 8.0.5. As always, ignore the minor version increment – this is a massive release. This release has new controls and a number of bug fixes, so it is recommended that everyone upgrade as soon as possible. As per usual, the latest version is always available in maven central (as well as snapshot versions of the next release), and you can download the release directly from the ControlsFX website.
This release was developed by Eugene Ryzhikov, Samir Hadzic, Dirk Lemmermann, David Grieve, IsNull, Dennis Fischer, Paul Jonas, Kouchuu, and I. It is because of these fine folks you can use ControlsFX, so be sure to give them a high-five if you pass them in the street.
If you aren’t familiar with ControlsFX, you should check out the main ControlsFX website, and more importantly, the ControlsFX features page. Once you’re done there you should take a look at our sample app and javadocs.
With that out of the way, here is what is new in ControlsFX 8.0.5:
With this you can provide suggestions to users as they type into a TextField. The popup will only show options based on the currently typed input.
The BreadCrumbBar control is designed to allow people to easily navigate back up a hierarchical page structure. It’s based on the same API as the TreeView control (that is, it uses the TreeItem structure). This control is useful to visualize and navigate a hierarchical path structure, such as file system. Here’s what it currently looks like:
The BreadCrumbBar UI control
A pane used to display a full-size content node and four initially hidden nodes on the four sides. The hidden nodes can be made visible by moving the mouse cursor to the edges of the pane. The hidden node will appear (at its preferred width or height) with a short slide-in animation. The node will disappear again as soon as the mouse cursor exits it. A hidden node / side can also be pinned, and it will remain visible as long as it stays pinned.
The HiddenSidesPane, with a node at the bottom that has animated into view.
This control was initially developed by my colleague David Grieve before being integrated into ControlsFX. It is designed to show a small blurb of text above a node (most commonly an ImageView, but it will work with any Node). The text can be collapsed down to a single line, or expanded to show the entire text. In some ways, it can be thought of as a always visible tooltip (although by default it is collapsed so only the first line is shown – hovering over it (or clicking on it if the showOnHover functionality is disabled) will expand it to show all text). Shown below is a screenshot of the InfoOverlay control in both its collapsed and expanded states:

A master / detail pane is used to display two nodes with a strong relationship to each other. Most of the time the user works with the information displayed in the master node but every once in a while additional information is required and can be made visible via the detail node. By default the detail appears with a short slide-in animation and disappears with a slide-out. This control allows the detail node to be positioned in four different locations (top, bottom, left, or right).

ControlsFX has had the NotificationPane feature for a release or two now, but that required that the notification appear within the window. Some use cases are to simply inform the user of an event, even when the main window itself is not visible (or focused) – think email notifications, for example. This is where the Notifications class comes in – it will show a notification message to users in one of nine locations on the screen, and even supports stacking multiple notifications, and showing complex scenegraphs. After a set duration, the notification will fade out.
A plus minus slider allows the user to continuously fire an event carrying a value between -1 and +1 by moving a thumb from its center position to the left or right (or top and bottom) edge of the control. The thumb will automatically center itself again on the zero position when the user lets go of the mouse button. Scrolling through a large list of items at different speeds is one possible use case for a control like this. You may be familiar with Google Picasa, which has a similar control for scrolling through the image list.

FXSampler Source Code Tab
FXSampler (the sample app we wrote for demonstrating ControlsFX, and which is open source to allow for third parties to use it to demonstrate their own software samples) now allows for displaying the source code for samples, making it even easier to teach people how to use new API. Here’s a screenshot:

There are always a number of improvements that fall under the radar for each release, but some of the more notable improvements include:
- Support for row resizing in the SpreadsheetView control.
- Glyph font loading is now lazy (which is important for FontAwesome as we download the font from the web when it is used).
- Support for CSS styling dialogs.
- There is now much better numeric field support in PropertySheet. It includes automatic support for editing integer and floating point values.
- ControlsFX dialogs are now about to be internationalized, and we’re planning to extend this internationalization support through to all controls in the next release. We already have English and Russian translations, and would happily accept other translations if people are willing.
That’s all for this release. Go forth, download and enjoy!
