ControlsFX class Dialogs
is marked as deprecated.
What to use instead?
Now with java 8 update 60, even using old non-deprecated version of controlsfx doesn't work. So, the solution is using the native dialog API from javafx included in java 8 update 40 (doesn't need 3rd party libs). They aren't as straight forward and full of features as controls fx. But for faster coding, you could create a wrapper class, like this one I made:
package br.atualy.devolucaodevenda.util;
import javafx.scene.control.*;
import javafx.scene.control.Label;
import javafx.scene.control.TextArea;
import javafx.scene.input.KeyCode;
import javafx.scene.input.KeyEvent;
import javafx.scene.layout.GridPane;
import javafx.scene.layout.Priority;
import javafx.stage.StageStyle;
import java.awt.*;
import java.io.PrintWriter;
import java.io.StringWriter;
import java.util.ArrayList;
import java.util.List;
import java.util.Optional;
public class FxDialogs {
public static void showInformation(String title, String message) {
Alert alert = new Alert(Alert.AlertType.INFORMATION);
alert.initStyle(StageStyle.UTILITY);
alert.setTitle("Information");
alert.setHeaderText(title);
alert.setContentText(message);
alert.showAndWait();
}
public static void showWarning(String title, String message) {
Alert alert = new Alert(Alert.AlertType.WARNING);
alert.initStyle(StageStyle.UTILITY);
alert.setTitle("Warning");
alert.setHeaderText(title);
alert.setContentText(message);
alert.showAndWait();
}
public static void showError(String title, String message) {
Alert alert = new Alert(Alert.AlertType.ERROR);
alert.initStyle(StageStyle.UTILITY);
alert.setTitle("Error");
alert.setHeaderText(title);
alert.setContentText(message);
alert.showAndWait();
}
public static void showException(String title, String message, Exception exception) {
Alert alert = new Alert(Alert.AlertType.ERROR);
alert.initStyle(StageStyle.UTILITY);
alert.setTitle("Exception");
alert.setHeaderText(title);
alert.setContentText(message);
StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw);
exception.printStackTrace(pw);
String exceptionText = sw.toString();
Label label = new Label("Details:");
TextArea textArea = new TextArea(exceptionText);
textArea.setEditable(false);
textArea.setWrapText(true);
textArea.setMaxWidth(Double.MAX_VALUE);
textArea.setMaxHeight(Double.MAX_VALUE);
GridPane.setVgrow(textArea, Priority.ALWAYS);
GridPane.setHgrow(textArea, Priority.ALWAYS);
GridPane expContent = new GridPane();
expContent.setMaxWidth(Double.MAX_VALUE);
expContent.add(label, 0, 0);
expContent.add(textArea, 0, 1);
alert.getDialogPane().setExpandableContent(expContent);
alert.showAndWait();
}
public static final String YES = "Yes";
public static final String NO = "No";
public static final String OK = "OK";
public static final String CANCEL = "Cancel";
public static String showConfirm(String title, String message, String... options) {
Alert alert = new Alert(Alert.AlertType.CONFIRMATION);
alert.initStyle(StageStyle.UTILITY);
alert.setTitle("Choose an option");
alert.setHeaderText(title);
alert.setContentText(message);
//To make enter key press the actual focused button, not the first one. Just like pressing "space".
alert.getDialogPane().addEventFilter(KeyEvent.KEY_PRESSED, event -> {
if (event.getCode().equals(KeyCode.ENTER)) {
event.consume();
try {
Robot r = new Robot();
r.keyPress(java.awt.event.KeyEvent.VK_SPACE);
r.keyRelease(java.awt.event.KeyEvent.VK_SPACE);
} catch (Exception e) {
e.printStackTrace();
}
}
});
if (options == null || options.length == 0) {
options = new String[]{OK, CANCEL};
}
List<ButtonType> buttons = new ArrayList<>();
for (String option : options) {
buttons.add(new ButtonType(option));
}
alert.getButtonTypes().setAll(buttons);
Optional<ButtonType> result = alert.showAndWait();
if (!result.isPresent()) {
return CANCEL;
} else {
return result.get().getText();
}
}
public static String showTextInput(String title, String message, String defaultValue) {
TextInputDialog dialog = new TextInputDialog(defaultValue);
dialog.initStyle(StageStyle.UTILITY);
dialog.setTitle("Input");
dialog.setHeaderText(title);
dialog.setContentText(message);
Optional<String> result = dialog.showAndWait();
if (result.isPresent()) {
return result.get();
} else {
return null;
}
}
}
To use the dialogs:
FxDialogs.showInformation("Hi", "Good Morning y'all!");
if (FxDialogs.showConfirm("Choose one baby!", "Can i ask you a question?", FxDialogs.YES, FxDialogs.NO).equals(FxDialogs.YES)) {
FxDialogs.showWarning(null, "Pay attention to my next question!");
String answer = FxDialogs.showTextInput("Are you a pink elephant disguised as a flying pig?", "Tell me!", "No");
FxDialogs.showError(null, "You should not have said " + answer + "!");
FxDialogs.showException("Now i'm angry", "I'm going home...", new RuntimeException("Exception caused by angry dinossaurs"));
}
