I'm using a indicator progress set to -1.0 to show some loading while loginprocess is running.
But when I press the Enter button and start my executor with the loginProcess, my interface stays freezed even if I use Plataform.runLater to set visible my ProgressIndicator.
My button event:
public void initManager(final LoginManager loginManager) {
btnEntrar.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
String email = loginTxtField.getText().trim();
String token = tokenTxtField.getText().trim();
if (email.equals("")) {
Platform.runLater(new Runnable() {
public void run() {
Dialog.showError("Erro", "Digite o e-mail");
}
});
return;
}
try {
Future future = loginProcess(email, token);
showLoginLoading(future);
future.get();
if (!loginGatewayFailed && !loginTargetAppFailed) {
Login loginTargetApp = new Login(email, null, null);
loginManager.autheticated(loginTargetApp, loginGateway, gateway, file);
} else {
if (loginTargetAppFailed) {
Platform.runLater(new Runnable() {
public void run() {
Dialog.showError("Erro", loginTargetAppFailedCause);
}
});
} else {
if (loginGatewayFailed) {
Platform.runLater(new Runnable() {
public void run() {
Dialog.showError("Erro", loginGatewayFailedCause);
}
});
}
}
}
} catch (final Exception ex) {
Logger.getLogger(LoginController.class.getName()).log(Level.SEVERE, ex.getMessage());
Platform.runLater(new Runnable() {
public void run() {
Dialog.showError("Erro", ex.getMessage());
}
});
}
}
});
}
My loginProcess:
public Future<?> loginProcess(String email, String token) throws Exception {
// MY PROCESS
return Executors.newSingleThreadExecutor().submit(new LoginTask(this, email, token));
} catch (Exception e) {
Logger.getLogger(LoginController.class.getName()).log(Level.SEVERE, e.getMessage());
throw e;
}
}
method showLoginLoading:
private void showLoginLoading(Future future) {
while (!future.isDone()) {
Platform.runLater(new Runnable() {
@Override
public void run() {
progressInd.setVisible(true);
// progressInd.setProgress(-1.0);
}
});
}
}
The problem was in thread management. I was trying to execute the login instructions in the same thread that the main FX view runs. I figured it out using the Platform.isFxApplicationThread(); It returns true if the calling thread is the JavaFX Application Thread.
To fix my problem i just needed to create a new thread to run all my login instructions as you can see in bellow example:
public void initManager(final LoginManager loginManager) {
btnEntrar.setOnAction(new EventHandler<ActionEvent>() {
boolean mainThread = Platform.isFxApplicationThread();
System.out.println("This is the main Thread: " + mainThread);
Platform.runLater(new Runnable() {
@Override
public void run() {
progressInd.setVisible(true);
}
});
new Thread() {
public void run() {
boolean mainThread = Platform.isFxApplicationThread();
System.out.println("This is the main Thread: " + mainThread);
String email = loginTxtField.getText().trim();
String token = tokenTxtField.getText().trim();
if (email.equals("")) {
Platform.runLater(new Runnable() {
public void run() {
Dialog.showError("Erro", "Digite o e-mail");
}
});
return;
}
try {
Future future = loginProcess(email, token);
// showLoginLoading(future);
future.get();
if (!loginGatewayFailed && !loginTargetAppFailed) {
Login loginTargetApp = new Login(email, null, null);
loginManager.autheticated(loginTargetApp, loginGateway, gateway, file);
} else {
if (loginTargetAppFailed) {
Platform.runLater(new Runnable() {
public void run() {
Dialog.showError("Erro", loginTargetAppFailedCause);
}
});
} else {
if (loginGatewayFailed) {
Platform.runLater(new Runnable() {
public void run() {
Dialog.showError("Erro", loginGatewayFailedCause);
}
});
}
}
}
} catch (final Exception ex) {
Logger.getLogger(LoginController.class.getName()).log(Level.SEVERE, ex.getMessage());
Platform.runLater(new Runnable() {
public void run() {
Dialog.showError("Erro", ex.getMessage());
}
});
}
}
}.start();
});
}
