In the next Bio7 release it will be possible to create custom GUI’s with the JavaFX Builder or with the new JavaFX API. I already integrated an API to load and compile a *.fxml file into a custom view of Bio7. GUI interfaces can easily be created with the new available JavaFX Scene Builder from Oracle and saved in a project of the Bio7 workspace. Objects and actions are accessible by means of Dependency Injection using the @FXML annotation.
Furthermore in the next release several custom views can be created side by side (i removed the tab implementation) e.g. to combine several custom GUI’s and panels. In the screenshot below an example shows the created GUI of the Scene Builder (screenshot above) side by side with three other custom views (processing API examples).
