The default SWT dialogs are listed below. The following code demonstrates the usage of the MessageBox class to open a message dialog.
JFace contains several frequently used dialogs which are not based on the native dialogs as well as a framework for building custom dialogs. The MessageDialog class provides static methods to open commonly used dialogs, for example an information or a warning dialog. The following code demonstrates the usage of these static methods. The MessageDialog class also allows the customization of the buttons in the dialog. The following code demonstrates its usage. Several of these dialogs return the user selection, e.
The following example code prompts the user for confirmation and handles the result. The ErrorDialog class can be used to display one or more errors to the user.
If an error contains additional detailed information then a button is automatically added, which shows or hides this information when pressed by the user.
If you trigger this handler, the dialog shows the exception messages and the detail page contains the stacktrace, as depicted in the following screenshot. The org. Dialog class can be extended to create your own dialog implementation. This class creates an area in which you can place controls and add an OK and Cancel button or other custom buttons.
Your class needs to implement the createDialogArea method. This method gets a Composite which expects to get a GridData object assigned as its layout data.
Via the super. This is demonstrated by the following example code. TitleAreaDialog has a reserved space for providing feedback to the user. You can set the text in this space via the setMessage and setErrorMessage methods. The usage of this dialog is demonstrated in the following code snippet. This code might for example be used in a handler.
I have to display a message box on some action, I am able to do that but the message dialog box appears smaller in size. Is there any way to increase the size of the message box in java?

Here's my version: You don't hardcode your dialog size, rather make it variable on the user's screen size. This would be far more flexible than an OS MessageBoxbut you're gonna have to add icons manually oooooor I think you can even override MessageDialog instead of Dialog - your call. Learn more.

Constructs a new instance of this class given its parent and a style value describing its behavior and appearance. Sets the dialog's message, which is a description of the purpose for which it was opened. The style value is either one of the style constants defined in class SWT which is applicable to instances of this class, or must be built by bitwise OR 'ing together that is, using the int " " operator two or more of those SWT style constants.

The class description lists the style constants that are applicable to the class. Style bits are also inherited from superclasses. Returns the dialog's message, or an empty string if it does not have one. The message is a description of the purpose for which the dialog was opened. This message will be visible in the dialog while it is open. This message will be visible on the dialog while it is open.
It works fine but i button titles are "Abort", "Retry", "ignore" I want custom button titles, like "overwrite", "rename", "cancel". How it can be done?
Please help. Here is a very simple example on how to do your own Dialog in SWT there are more comfortable ways to do this with JFace though :. MessageBox cannot be extended this way. Your best option - when not doing an RCP application - probably is to roll your own dialog I'm a little late to this, but if anyone else is looking for a cutomizable MessageBox, here it is.

A dialog is defined as a conversation between two or more persons. In a computer application a dialog is a window which is used to "talk" to the application.
A dialog is used to input data, modify data, change the application settings etc. Dialogs are important means of communication between a user and a computer program. MessageBox is a simple dialog that provides some information to the user. It can contain messages, icons, and various buttons. Icons and buttons are chosen with available MessageBox styles. For instance, the SWT. There is one push button on the window. Clicking on the button displays an information message dialog. An instance of the MessageBox is created, taking the style as the second parameter.
In order to prevent data loss, data-centric applications often show a confirmation dialog when being closed. Only after the dialog is confirmed, the application terminates. The confirmation dialog is modal and contains a Question icon and Yes and No buttons. Modal dialogs block the main application until they are dismissed. In our example, we select a directory with the DirectoryDialog and display its path in the statusbar. The dialog is shown by clicking on the area of the window.
A mouse listener for the SWT. MouseDown event is added to the shell. When we press a mouse button on the window, the onMouseDown method is invoked. FontDialog is a dialog for selecting fonts. It is typically used in applications that do some text editing or formatting. The example is very similar to the previous one. This time we change the colour of the label.
The ColorDialog is shown by clicking on the window area.

The code example uses the FileDialog to select a file. The dialog uses a filter to show only the Java sources. The name of the chosen file is shown in the label. OPEN flag. The dialog can be used both to open or save files.
The save behaviour of the dialog is enabled with the SWT. SAVE constant. The path name is set to the label with the setText method. The label and the shell are adapted to the size of the returned path with the pack method.Instead, the ID is the index of the button in the supplied array. The labels of the buttons to appear in the button bar are supplied in this constructor as an array.
The open method will return the index of the label in this array corresponding to the button that was pressed to close the dialog. Note: If the dialog was dismissed without pressing a button ESC key, close box, etc. Note that the open method blocks. The labels of the buttons to appear in the button bar are supplied in this constructor as a varargs of Strings. The Dialog implementation of this framework method calls okPressed if the ok button is the pressed, and cancelPressed if the cancel button is the pressed.
All other button presses are ignored. Subclasses may override to handle other buttons, but should call super. The default implementation of this framework method sets the shell's image and gives it a grid layout.
Subclasses may extend or reimplement. The Dialog implementation of this framework method adds standard ok and cancel buttons using the createButton framework method. Subclasses may override. On some platforms, Dialog.
The default implementation of this framework method returns null. The Dialog implementation of this framework method creates a standard push button, registers it for selection events including button presses, and registers default buttons with its shell.
The button id is stored as the button's client data. If the button id is IDialogConstants. Note that the parent's layout is assumed to be a GridLayout and the number of columns in this layout is incremented. Object org. Window org. Dialog org.
