POBest way to wait for input in a for loop?

copied!<p>In JavaFX 2 I have a TableView beeing populated by reading an Excel file. It looks like this:</p> <pre><code>identification cellcount calved o0001 12345 false o0002 65432 true o0003 55555 false ... </code></pre> <p>When users press the 'Import' button, all records have to be added to a database. However, If the 'calved' field has 'true' as value, I show a Dialog window where the users have to select a date to specify when the calving happened. Now the big question is that I want my for loop beeing paused as soon as a Dialog window is open. With my current code, all Dialog windows are stacked on eachother.</p> <p>This is the Dialog method which loads an FXML:</p> <pre><code>public void showDialog(String sURL){ final Stage myDialog = new Stage(); myDialog.initStyle(StageStyle.UTILITY); myDialog.initModality(Modality.APPLICATION_MODAL); URL url = getClass().getResource(sURL); FXMLLoader fxmlloader = new FXMLLoader(); fxmlloader.setLocation(url); fxmlloader.setBuilderFactory(new JavaFXBuilderFactory()); try { Node n = (Node) fxmlloader.load(url.openStream()); Scene myDialogScene = new Scene(VBoxBuilder.create().children(n).alignment(Pos.CENTER).padding(new Insets(0)).build()); myDialog.setScene(myDialogScene); myDialog.show(); } catch (Exception ex) { System.out.println(ex); } } </code></pre> <p>And here is the for loop where I handle the tablerows:</p> <pre><code>@FXML private void handle_ImportCowDataButton(ActionEvent event) { Cows selectedCow; for(ImportRow row: tblImport.getItems()){ selectedCow = null; for (Cows cow : olCows) { if (cow.getOfficial().equals(row.getCownumber())) { selectedCow = cow; } } if (selectedCow != null) { if (row.getCalving()) { //if cow exists and cow has calved, show dialog window loading addcalving.fxml //then the for loop should wait until that dialog window is closed before continuing Context.getInstance().setPassthroughObject(selectedCow); Context.getInstance().showDialog("/GUI/calving/AddCalving.fxml"); } } else { //if cow does not exist, show dialog window loading addcow.fxml //then the for loop should wait until that dialog window is closed before continuing Context.getInstance().setPassthroughObject(selectedFarmer); Context.getInstance().showDialog("/GUI/cow/AddCow.fxml"); } } } </code></pre> <p>Is working with <code>setOnCloseRequest()</code> in my <code>showDialog()</code> method an option?</p>
