JavaFX - Wizard UI


This demonstrates implementation of simple wizard user interface using a combination of Container, Button and bind.

I have a main Container - Wizard. This has the navigation buttons and a sequence of Containers - WizardPanel, which contains the user interface for each panel. A variable selectedIndex in Wizard keeps track of currently shown panel. Variable selectedPanel holds the instance of selected panel. A new panel instance is set to this variable when index is updated. The node is bound to content so as to update UI when a new panel is set. Disabled state of "Back" and "Next" button is set dynamically using bind with selectedIndex.

The panels in demo uses a series of SVG images - Duke, Lamborghini and Tiger. Its converted into FXZ format using JavaFX Production Suite - SVG Converter and ofcourse the text is from wikipedia

JavaFX - How to Layout


Just thought of providing an outline for design and implementation of JavaFX application. I briefly described this in one of previous post - Custom Layout.To start with we will most likely receive a huge PSD file from designer. You may use Production Suite tools to import the content into JavaFX. Here is manual approach..

First we need to identify various functional areas in the UI. Most likely the UI is already grouped. Areas can be Settings, Authentication, Data-Entry/Update View, ToolBar, Search etc. From this we can identify set of packages to be created in JavaFX. If the UI is simple, we may have the entire UI under "view" package. Now we can breakup the UI in to multiple classes based on the functional area. It will be easier if we could make these classes extend Container or CustomNode. From there we come down to actual layout of Controls..

Given below is the layout used in one of MiG Layout Demos - Layout Showdown. Refer to MiG Layout Site for more information. Refer to JFXtras project for more information on MiG Layout for JavaFX.

We will try to implement this UI in JavaFX..

Now we need to visualize a grid on top of the layout so as to identify some pattern in UI. It will be much easier if we could do this mapping. You may refer to various sites such as Layout Cookbook, RIA Screen Layouts or RIA Screen Design to get some idea..

Once we get the mapping, we can implement the layout using various layoutNode functions in Container. Please refer to PersonalDetailsView.fx source for more information.
