Passing parameters between two JavaFX controllers

Question

I want to click a column and send the cell index to a new stage. But I can\'t pass my parameter (int clickIndex) to another controller EditClientControlle

Answer 1

When moving from one controller to another(one view to another), you could initialize the EditClientController with the required parameters

Eg:

FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("editClient.fxml"));
EditClientController ctrl = new EditClientController();
ctrl.setCellIndex(id);
fxmlLoader.setController(ctrl);

If you have specified the controller in the fxml file, the you could use:

editWrapper.getCurrentController().setCellIndex(id);

where editControllerWrapper is a class that loads the new view and has a method getCurrentController that returns an instance of javafx controller.

Eg: public class EditControllerWrapper {

private Parent root;


public EditControllerWrapper () {
    try
    {
        FXMLLoader loader = new FXMLLoader(getClass().getResource("editClient.fxml"),                           
        ...
    } catch (Exception e) {
        ...
    }
}


public  T getCurrentController ()  {
    return loader.getController();
}
