Field Details

NOT_CANCELABLE

public static final ProgressDialog.Option NOT_CANCELABLE

Option to pass to make the Cancel button inactive, forcing the user to wait until the task is completed.

Constructor Details

ProgressDialog

public ProgressDialog(Window parent,
 ProgressTask<T> task,
 ProgressDialog.Option... options)

Creates new form ProgressDialog.

Parameters:

parent - The parent window for the modal dialog.

task - The task to execute.

options - Optional modifiers to change the behaviour. See NOT_CANCELABLE and NO_FOCUS_STEALING.

Method Details

setVisible

public void setVisible(boolean b)

When invoked with true, displays the dialog and starts the configured ProgressTask in a background thread, then blocks until the task has completed and the dialog is disposed of. Events are dispatched while this method is blocked.

Overrides:

setVisible in class Dialog

Parameters:

b - true to show the dialog and start the task in a background thread.

executeTask

public static <T> T executeTask(Window parent,
 ProgressTask<T> task,
 ProgressDialog.Option... options)

Execute a task in the background with progress reporting via a modal dialog with a progress bar. The task is executed on a separate thread. This method blocks until the task has completed, but events are dispatched while the method is blocked. If the task throws an exception, that exception will be rethrown by this method.

By default the Cancel button is enabled and the popup will steal the keyboard focus. Use one or more of the NOT_CANCELABLE and NO_FOCUS_STEALING options to modify this.

Type Parameters:

T - The return type of the task. Use Void for tasks which don't return a value.

Parameters:

parent - The parent window for the modal dialog.

task - The task to execute.

options - Optional modifiers to change the behaviour. See NOT_CANCELABLE and NO_FOCUS_STEALING.

Returns:

The result of the task, or null if the task does not return a result or if it was cancelled.

Throws:

Error - If the task threw an Error.

RuntimeException - If the task threw a RuntimeException.

executeTask

 String name,
 Callable<T> task,
 ProgressDialog.Option... options)

Execute a task in the background with progress reporting via a modal dialog with a progress bar. The task is executed on a separate thread. This method blocks until the task has completed, but events are dispatched while the method is blocked. If the task throws an exception, that exception will be rethrown by this method.

By default the Cancel button is enabled and the popup will steal the keyboard focus. Use one or more of the NOT_CANCELABLE and NO_FOCUS_STEALING options to modify this.
