[SOLVED] Load MenuItem accelerators into FXML from a configuration file?

Load MenuItem accelerators into FXML from a configuration file?

I am developing an application which now has an extensive Menu with Accelerators.

I am looking for a way to make it possible for the user to bind the keys for certain functions and save the key bindings for the next startup.

Is there a way to load MenuItem accelerators for an FXML file from a configuration file?

Otherwise, I would probably need to serialize a map for each MenuItem function individually.

Thanks in advance for any info.

Solution

You can use KeyCombination.getName() to get a String representation of a MenuItem accelerator and KeyCombination.keyCombination(String) to create a MenuItem accelerator from a String representation. See example:

KeyCombination accelerator =  new KeyCodeCombination(KeyCode.D, KeyCombination.CONTROL_DOWN);
MenuItem menuItem = new MenuItem("Click me");
menuItem.setAccelerator(accelerator);

...

//save accelerator to the config file
String accString = menuItem.getAccelerator().getName();
saveAcceleratorToConfig(accString); // save string to file

...

//load accelerator from the config file
String accString = loadAcceleratorFromConfig(); //load string from file
menuItem.setAccelerator(KeyCombination.keyCombination(accString));
