Dialog Scene

[Tamar Navratil]

Maybethey can add extra function to the already existing keyboard shortcut that opens the scene variable editor, so that it will open not just when you are in the scene layout editor tab but also when you are in the scene events editor tab. Or if they add a button to the toolbar maybe they can let it be something the user can disable to prevent clutter.

Not exactly. If you have the Hidden Geometry setting unchecked for a Scene, it means hidden and visible entities will remain unchanged when switching to the Scene from another. It means the Scene does not update what is hidden and visible when the Scene is selected. It means hidden entities remain hidden and visible entities remain visible.

All of the Scene options are consistent and logical. If an option is checked, the Scene uses the settings to update the view. If an option is not checked, the Scene does not use the settings to update the view.

If I understand this correctly, checking the Hidden Geometry property to save ON and saving or updating a scene, that hidden geometry visibility should be maintained when one opens that scene.

This is NOT what is happening!

If you insist upon using Hide to control visibility then this little plugin will probably come in handy.

You might also find it useful to insure nothing remains hidden should you decide to adopt Layers.

The Scene Properties can be quite a brain twist especially since there are so many variables to know about. Dont let this dishearten you because what you are trying to achieve can be done while leaving all the settings CHECKED. In fact most users dont mess with these properties that often. I, myself, tend to only turn off Camera Location when I dont want to set camera views from scene to scene.

When two people gather in a room to talk things through like adults, what happens in mostly pretty standard; if everything goes right, both individuals shake hands and go back to the world with a smile on their faces and one reason less to worry.

This movie consists of a single scene of dialogue, stretched for over two hours, in which the protagonist reunites with an old friend named Andre, who has been involved in an interesting series of activities in a search for real meaning in his life.

Wally calmly listens as his friend enthusiastically describes what he has been doing all this time: being buried alive, making a weird play with no audience in a forest, adopting a Buddhist monk for a few weeks, joining a group of people who were trying to achieve a kind of enlightened extra-human state. Andre seems to be into new age culture, and he and Wally are very dissimilar.

Holly Martins has arrived to post-World War II Vienna, following an invitation from his old friend Harry Lime. Just after his arrival, Holly is informed that Harry was run over by a truck and died instantly. He assists with the funeral and everyone seems to think that Harry was a criminal. Holly then starts a difficult investigation process to prove the innocence of his best buddy.

Soon enough, Henry finds out that Tommy is only messing with him and everybody starts laughing again. However, we also see how much of a lunatic Tommy is, which makes us wonder if Henry is safe by his side.

Michael Fassbender plays Bobby Sands, an Irish republican who leads a hunger strike while imprisoned. He has a conversation with Father Dominic about his life, religion and motives, a relaxed chat while smoking and displaying a great amount of chemistry. The camera is static as both men interrogate one another.

The Dialog class has a single generic type, R, which is used to represent the type of the result property (and also, how to convert from ButtonType to R, through the use of the result converter Callback). Critical note: It is critical that all developers who choose to create their own dialogs by extending the Dialog class understand the importance of the result converter property. A result converter must always be set, whenever the R type is not Void or ButtonType. If this is not heeded, developers will find that they get ClassCastExceptions in their code, for failure to convert from ButtonType via the result converter. It is likely that most developers would be better served using either the Alert class (for pre-defined, notification-style alerts), or either of the two pre-built dialogs (TextInputDialog and ChoiceDialog), depending on their needs. Once a Dialog is instantiated, the next step is to configure it. Almost all properties on Dialog are not related to the content of the Dialog, the only exceptions are contentTextProperty(), headerTextProperty(), and graphicProperty(), and these properties are simply forwarding API onto the respective properties on the DialogPane stored in the dialog pane property. These three properties are forwarded from DialogPane for developer convenience. For developers wanting to configure their dialog, they will in many cases be required to use code along the lines of dialog.getDialogPane().setExpandableContent(node). After configuring these properties, all that remains is to consider whether the buttons (created using ButtonType and the DialogPane.createButton(ButtonType) method) are fully configured. Developers will quickly find that the amount of configurability offered via the ButtonType class is minimal. This is intentional, but does not mean that developers can not modify the buttons created by the ButtonType that have been specified. To do this, developers simply call the DialogPane.lookupButton(ButtonType) method with the ButtonType (assuming it has already been set in the DialogPane.getButtonTypes() list. The returned Node is typically of type Button, but this depends on if the DialogPane.createButton(ButtonType) method has been overridden. A typical approach is therefore along the following lines: ButtonType loginButtonType = new ButtonType("Login", ButtonData.OK_DONE); Dialog dialog = new Dialog(); dialog.getDialogPane().getButtonTypes().add(loginButtonType); boolean disabled = false; // computed based on content of text fields, for example dialog.getDialogPane().lookupButton(loginButtonType).setDisable(disabled); Once a Dialog is instantiated and fully configured, the next step is to show it. More often than not, dialogs are shown in a modal and blocking fashion. 'Modal' means that the dialog prevents user interaction with the owning application whilst it is showing, and 'blocking' means that code execution stops at the point in which the dialog is shown. This means that you can show a dialog, await the user response, and then continue running the code that directly follows the show call, giving developers the ability to immediately deal with the user input from the dialog (if relevant). JavaFX dialogs are modal by default (you can change this via the initModality(javafx.stage.Modality) API). To specify whether you want blocking or non-blocking dialogs, developers simply choose to call showAndWait() or show() (respectively). By default most developers should choose to use showAndWait(), given the ease of coding in these situations. Shown below is three code snippets, showing three equally valid ways of showing a dialog: Option 1: The 'traditional' approach Optional result = dialog.showAndWait(); if (result.isPresent() && result.get() == ButtonType.OK) formatSystem(); Option 2: The traditional + Optional approach dialog.showAndWait().ifPresent(response -> if (response == ButtonType.OK) formatSystem(); ); Option 3: The fully lambda approach dialog.showAndWait() .filter(response -> response == ButtonType.OK) .ifPresent(response -> formatSystem()); There is no better or worse option of the three listed above, so developers are encouraged to work to their own style preferences. The purpose of showing the above is to help introduce developers to the Optional API, which is new in Java 8 and may be foreign to many developers. Dialog Validation / Intercepting Button Actions In some circumstances it is desirable to prevent a dialog from closing until some aspect of the dialog becomes internally consistent (e.g. a form inside the dialog has all fields in a valid state). To do this, users of the dialogs API should become familiar with the DialogPane.lookupButton(ButtonType) method. By passing in a ButtonType (that has already been set in the button types list), users will be returned a Node that is typically of type Button (but this depends on if the DialogPane.createButton(ButtonType) method has been overridden). With this button, users may add an event filter that is called before the button does its usual event handling, and as such users may prevent the event handling by consuming the event. Here's a simplified example: final Button btOk = (Button) dlg.getDialogPane().lookupButton(ButtonType.OK); btOk.addEventFilter(ActionEvent.ACTION, event -> if (!validateAndStore()) event.consume(); ); Dialog Closing Rules It is important to understand what happens when a Dialog is closed, and also how a Dialog can be closed, especially in abnormal closing situations (such as when the 'X' button is clicked in a dialogs title bar, or when operating system specific keyboard shortcuts (such as alt-F4 on Windows) are entered). Fortunately, the outcome is well-defined in these situations, and can be best summarised in the following bullet points: JavaFX dialogs can only be closed 'abnormally' (as defined above) in two situations: When the dialog only has one button, or When the dialog has multiple buttons, as long as one of them meets one of the following requirements: The button has a ButtonType whose ButtonBar.ButtonData is of type ButtonBar.ButtonData.CANCEL_CLOSE. The button has a ButtonType whose ButtonBar.ButtonData returns true when ButtonBar.ButtonData.isCancelButton() is called. In all other situations, the dialog will refuse to respond to all close requests, remaining open until the user clicks on one of the available buttons in the DialogPane area of the dialog. If a dialog is closed abnormally, and if the dialog contains a button which meets one of the two criteria above, the dialog will attempt to set the result property to whatever value is returned from calling the result converter with the first matching ButtonType. If for any reason the result converter returns null, or if the dialog is closed when only one non-cancel button is present, the result property will be null, and the showAndWait() method will return Optional.empty(). This later point means that, if you use either of option 2 or option 3 (as presented earlier in this class documentation), the Optional.ifPresent(java.util.function.Consumer) lambda will never be called, and code will continue executing as if the dialog had not returned any value at all.
