Class BlockingExample1
A demo of the
@Action
block options for background
task. It's an example of three of the Action.Block
types:
@Action(block = Task.BlockingScope.ACTION) public Task blockAction() { ... } @Action(block = Task.BlockingScope.COMPONENT) public Task blockComponent() { ... } @Action(block = Task.BlockingScope.WINDOW) public Task blockWindow() { ... } @Action(block = Task.BlockingScope.APPLICATION) public Task blockApplication() { ... }The first
BlockingScope.ACTION
@Action
disables the
corresponding Action
while blockAction
method runs.
When you press the blockAction button or toolbar-button or menu
item you'll observe that all of the components are disabled. The
BlockingScope.COMPONENT
version only disables the component
that triggered the action. The Block.WINDOW
method
uses a custom inputBlocker
to
temporarily block input to the by making the window's
glass pane visible. And the Task.BlockingScope.APPLICATION
version pops up a modal dialog for the action's duration.
The blocking dialog's title/message/icon are defined by resources
from the ResourceBundle named BlockingExample1
:
BlockingDialog.title = Blocking Application BlockingDialog.message = Please wait patiently ... Action.BlockingDialog.icon = wait.png
All of the actions in this example just sleep for about 2 seconds, while periodically updating their Task's message/progress properties.
This class loads resources from the ResourceBundle called
BlockingExample1
. It depends on the example StatusBar
class.
