Is there a quick way to remove a Dialog header in JavaFX? Or should i just go and create my own dialog?
TextInputDialog dialog = new TextInputDialog();
dialog.setTitle("create DATABASE");
dialog.setHeaderText("create DATABASE");
dialog.setContentText("Ingrese un nombre:");
dialog.showAndWait().ifPresent(name -> getCodeArea().setTemplateInjump("create database "+name+";\n\nuse "+name+";\n\n"));
Yes, you can achieve this by setting the graphic and header text to null:
dialog.setHeaderText(null);
dialog.setGraphic(null);
It's very simple set dialog.setHeaderText(null) and it will remove the header.

I'm trying to play a video in a alert dialog using JavaFX. The problem is that I can't find how to display the video or more how to insert it in the alert ?
Here is my alert code
MediaPlayer player = new MediaPlayer( new Media(getClass().getResource("video.mp4").toExternalForm()));
MediaView mediaView = new MediaView(player);
private void alert(){
Alert alert = new Alert(Alert.AlertType.ERROR);
alert.setTitle("Don't be a fool");
alert.setHeaderText("");
alert.setContentText("Do you really think your time is correct ?");
Optional<ButtonType> result = alert.showAndWait();
}
An Alert extends from Dialog, which means you can customize its DialogPane. If you want to add a video to your alert, the best place is probably the dialog pane's content. But note that setting the content will replace the contentText (which you set in your example code):
In addition to the header and content properties, there exists header text and content text properties. The way the *Text properties work is that they are a lower precedence compared to the Node properties, but they are far more convenient for developers in the common case, as it is likely the case that a developer more often than not simply wants to set a string value into the header or content areas of the DialogPane.
This means, if you still want to display "Do you really think your time is correct?", you'll have to add your own Label to the content as well. For example:
Alert alert = new Alert(Alert.AlertType.ERROR);
alert.setTitle("Don't be a fool");
alert.setHeaderText("");
Label label = new Label("Do you really think your time is correct?");
VBox content = new VBox(10, label, mediaView);
content.setAlignment(Pos.CENTER);
alert.getDialogPane().setContent(content);
alert.setOnShowing(e -> player.play());
alert.showAndWait();
Are AX dialog buttons limited to OK and Cancel?
Is it possible to add a custom button to the dialog?
I have the following code for my dialog:
static void mitTabPage(Args _args)
{
Dialog dialog;
DialogGroup dialoggroup, dialoggroup2;
DialogField dialogfield, dialogfield2;
;
dialog = new Dialog ("A new Dialog");
dialog.addTabPage("Brand Id's");
dialoggroup = dialog.addGroup("Brand Id's");
dialogfield = dialog.addField(extendedTypeStr(SYCCarBrandId));
dialog.addTabPage("Owners");
dialoggroup2 = dialog.addGroup("Owners");
dialogfield2 = dialog.addField(extendedTypeStr(SYCOwner));
dialog.run();
}
I'd like to add another button to the dialog. How can I do that?
The Dialog framework is a simple framework for prompting users to obtain some data/settings then performing some action or canceling.
For what you're trying to do, it most likely doesn't make sense to use the dialog framework and instead you could/should create another form if you need additional functionality.
However, if you do insist on using the Dialog framework for this, you would add a runtime button and use registerOverrideMethod.
See following links:

I would like to use the standard JavaFX Alert class for a confirmation dialog that includes a check box for "Do not ask again". Is this possible, or do I have to create a custom Dialog from scratch?
I tried using the DialogPane.setExpandableContent() method, but that's not really what I want - this adds a Hide/Show button in the button bar, and the check box appears in the main body of the dialog, whereas I want the check box to appear in the button bar.
Yes, it is possible, with a little bit of work. You can override DialogPane.createDetailsButton() to return any node you want in place of the Hide/Show button. The trick is that you need to reconstruct the Alert after that, because you will have got rid of the standard contents created by the Alert. You also need to fool the DialogPane into thinking there is expanded content so that it shows your checkbox. Here's an example of a factory method to create an Alert with an opt-out check box. The text and action of the check box are customizable.
public static Alert createAlertWithOptOut(AlertType type, String title, String headerText,
String message, String optOutMessage, Consumer<Boolean> optOutAction,
ButtonType... buttonTypes) {
Alert alert = new Alert(type);
// Need to force the alert to layout in order to grab the graphic,
// as we are replacing the dialog pane with a custom pane
alert.getDialogPane().applyCss();
Node graphic = alert.getDialogPane().getGraphic();
// Create a new dialog pane that has a checkbox instead of the hide/show details button
// Use the supplied callback for the action of the checkbox
alert.setDialogPane(new DialogPane() {
#Override
protected Node createDetailsButton() {
CheckBox optOut = new CheckBox();
optOut.setText(optOutMessage);
optOut.setOnAction(e -> optOutAction.accept(optOut.isSelected()));
return optOut;
}
});
alert.getDialogPane().getButtonTypes().addAll(buttonTypes);
alert.getDialogPane().setContentText(message);
// Fool the dialog into thinking there is some expandable content
// a Group won't take up any space if it has no children
alert.getDialogPane().setExpandableContent(new Group());
alert.getDialogPane().setExpanded(true);
// Reset the dialog graphic using the default style
alert.getDialogPane().setGraphic(graphic);
alert.setTitle(title);
alert.setHeaderText(headerText);
return alert;
}
And here is an example of the factory method being used, where prefs is some preference store that saves the user's choice
Alert alert = createAlertWithOptOut(AlertType.CONFIRMATION, "Exit", null,
"Are you sure you wish to exit?", "Do not ask again",
param -> prefs.put(KEY_AUTO_EXIT, param ? "Always" : "Never"), ButtonType.YES, ButtonType.NO);
if (alert.showAndWait().filter(t -> t == ButtonType.YES).isPresent()) {
System.exit();
}
And here's what the dialog looks like:
I am creating a JavaFX Dialog and want to use the default icons for Info/Warning/Error.
In Swing, I can get the Information icon this way:
UIManager.getIcon("OptionPane.informationIcon")
How can I do the same in JavaFX?
I asked for this some days ago. I use this code to make labels with default icons:
Label img = new Label();
img.getStyleClass().addAll("alert", "error", "dialog-pane");
dialog.setGraphic(img);
If you get a copy of the images you can use these ideas.
Alert example:
#FXML void handleHelpButton(ActionEvent event){
Alert alert = new Alert(AlertType.INFORMATION);
alert.setTitle("Help");
alert.setHeaderText("Help");
alert.setGraphic(new ImageView(this.getClass().getResource("img/help.png").toString()));
alert.setContentText("Place the cursor over a button for hint.");
Stage stage = (Stage) alert.getDialogPane().getScene().getWindow();
stage.getIcons().add(new Image(this.getClass().getResource("img/help.png").toString()));
alert.showAndWait();
}
Dialog example:
ChoiceDialog<String> dialog = new ChoiceDialog<>(currentFullscreenSetting, choices);
dialog.setTitle("Settings");
dialog.setHeaderText("Settings");
dialog.setContentText("Fullscreen on startup: ");
dialog.setGraphic(new ImageView(this.getClass().getResource("img/settings.png").toString()));
Stage stage2 = (Stage) dialog.getDialogPane().getScene().getWindow();
stage2.getIcons().add(new Image(this.getClass().getResource("img/settings.png").toString()));
// Traditional way to get the response value.
Optional<String> result = dialog.showAndWait();
This part of both examples is tricky. I noticed that this would not work unless I had the image in the same folder as the .fxml and controller.java files or in a folder that is in the same folder has the files mentioned. You might have to play with you file location. In my example it appears that my setGraphic and getIcons images are in the same folder, but they are not.
stage.getIcons().add(new
Image(this.getClass().getResource("img/help.png").toString()));
My file structure looks like:
PlanningChart
css
img
planningchart
img
The second img folder holds the images for stage.getIcons.add(). The images could also be probably use to for setGraphic. I did not try it.
You do not need to create custom JavaFX dialogs for Info/Warning/Error, since JavaFX already have created Alerts for you.
The Alert class subclasses the Dialog class, and provides support for a number of pre-built dialog types that can be easily shown to users to prompt for a response.
You can create different types of Alerts, depending on the AlertType, it will embed the necessary image.
For Information alert use :
Alert alert = new Alert(AlertType.INFORMATION);
alert.setTitle("Information Dialog");
alert.setHeaderText("An Information Dialog");
alert.setContentText("Information Message");
alert.showAndWait();
Similarly, for Warning alert, you can use
AlertType.WARNING
and for Error alert, you can use :
AlertType.ERROR
Is it possible to rename dialog box buttons?
For example on "okCancel" can I rename the "ok" button as "continue"?
If not please guide me how can I create my own dialog box?
Thanks ahead.
A button has a "Text" property.
You can set that property or do so by code:
okButton.text("Continue");
The Box::okCancel uses the DialogBox class which is a kernel class and cannot be changed.
The yesNoAxaptaForm method on the other hand uses an AX form, so you can roll on your own.
That said it seems to gain little value.
Also consider using the RunBase framework with a form, as demonstrated in the Tutorial_RunbaseForm class.
You can create a new method in class Dialog overwriting the control #okButton and call this method in your new dialog.
When Dialog class is create in the method new call the method initButtons, which can be overridden.
For example:
FormBuildButtonGroupControl buttonGroup;
formBuildCommandButtonControl okButton;
;
buttonGroup = dialogForm.buildDesign().control(#bottomGroup);
if (buttonGroup)
{
okButton = dialogForm.buildDesign().control(#okButton);
okButton.text("test");
}
