[FIXED] JavaFX: Identical tabs with different data

Issue

In Lazarus, there are 2 different kinds of tab elements (cf. Free Pascal docs):

TPageControl

TPageControl is a multi-page component that provides a container to hold a variety of controls per page.

TTabControl

It is a tabbed container component which looks identical to a TPageControl. However, there is a fundamental difference because the control always shows the same page whichever tab is selected. In fact, it containts only a single page. The idea behind this concept is illustrated best by an editor or viewer for text files: When the TabControl contains a TMemo then the individual tabs refer to the files loaded into the memo; whenever the active tab changes another file is loaded into the (same) memo.

In this sense, JavaFX TabPanes are quite similar to TPageControls, but I rather want to replicate a TTabControl. I know I could in fact programmatically create a new Tab(), but I want to visually design it in SceneBuilder.

Is there maybe a way to load a separate .fxml file into a new Tab() element which is then added to the TabPane? (And how could I then access a tab's children?)

Solution

I chose the easiest approach: Implementing a head-less TabPane to detect when the user switches between tabs. The elements that appear to the user as the “tab content” are actually placed outside the TabPane, and their content is dynamically changed whenever the tab is switched.
