Platform#runLater Question

[Florian Brunner]

Hi Mark,

I'm not sure if it fits your needs exactly, but I've implemented something like this for Drombler FX.

The JavaFX agnostic interface is here:
http://sourceforge.net/p/drombler/drombler-acp/ci/f2c9da0d549677805fbcb3c5250e139a5d8925fb/tree/drombler-acp-core-application/src/main/java/org/drombler/acp/core/application/ApplicationExecutorProvider.java

The JavaFX specific implementation class and helpers are here:
http://sourceforge.net/p/drombler/drombler-fx/ci/9639d43d9c015b15f770df1b92c716c8d86def46/tree/drombler-fx-core-application/src/main/java/org/drombler/fx/core/application/impl/FXApplicationExecutorProvider.java
http://sourceforge.net/p/drombler/drombler-fx/ci/9639d43d9c015b15f770df1b92c716c8d86def46/tree/drombler-fx-core-application/src/main/java/org/drombler/fx/core/application/impl/FXApplicationExecutor.java
http://sourceforge.net/p/drombler/drombler-fx/ci/9639d43d9c015b15f770df1b92c716c8d86def46/tree/drombler-fx-core-commons/src/main/java/org/drombler/fx/core/commons/fx/application/PlatformUtils.java

So instead of calling Platform.runLater() directly, I inject an implementation of  ApplicationExecuterProvider and call ApplicationExecuterProvider.getApplicationExecutor().execute().

Here is an example how you can use it with OSGi Declarative Services (using the Apache Felix SCR annotations):
http://sourceforge.net/p/drombler/drombler-acp/ci/f2c9da0d549677805fbcb3c5250e139a5d8925fb/tree/drombler-acp-core-action-spi/src/main/java/org/drombler/acp/core/action/spi/impl/ToolBarsHandler.java#l41

(The reason I'm doing this is because Drombler ACP, the base framework of Drombler FX, is GUI-toolkit agnostic and thus doesn't know anything about JavaFX.)
