Class Fields
static function getManager(theStage:Stage): FocusManager
Returns the current FocusManager instance
@see #setCurrentManager
| returns | this the current FocusManager instance |
static function isDefaultTraversalEnabled(): Bool
Returns the default value for defaultTraversalEnabled.
@see #setTraversalEnabled()
@see #setTraversalAsDefault()
static function setDefaultTraversalEnabled(b:Bool): Void
The default to disables or enables the traversal by keys pressing. @see #setTraversalEnabled() @see #setTraversalAsDefault()
static function setManager(theStage:Stage, newManager:FocusManager): Void
Sets the current FocusManager instance. If null is specified, then the current FocusManager is replaced with a new instance of FocusManager.
@see #getCurrentManager @see org.aswing.FocusManager
| newManager | the new FocusManager |
Instance Fields
function focusNextOfComponent(aComponent:Component): Void
Focuses the Component after aComponent, typically based on a FocusTraversalPolicy.
@see FocusTraversalPolicy
| aComponent | the Component that is the basis for the focus traversal operation |
function focusPrevious(): Void
Focuses the Component before the current focus owner. @see #focusPreviousOfComponent()
function focusPreviousOfComponent(aComponent:Component): Void
Focuses the Component before aComponent, typically based on a FocusTraversalPolicy.
@see FocusTraversalPolicy
| aComponent | the Component that is the basis for the focus traversal operation |
function getActiveWindow(): JWindow
Returns the active Window. The active Window is always either the focused Window, or the first Window that is an owner of the focused Window.
@see #setActiveWindow()
| returns | the active Window |
function getDefaultFocusTraversalPolicy(): FocusTraversalPolicy
Returns the default FocusTraversalPolicy. Top-level components use this value on their creation to initialize their own focus traversal policy by explicit call to Container.setFocusTraversalPolicy.
@see #setDefaultFocusTraversalPolicy() @see Container#setFocusTraversalPolicy() @see Container#getFocusTraversalPolicy()
| returns | the default FocusTraversalPolicy. null will never be returned. |
function getFocusOwner(): Component
Returns the focus owner.
@see #setFocusOwner()
| returns | the focus owner. |
function getPreviousFocusedComponent(): Component
Returns the previous focused component.
| returns | the previous focused component. |
function init(theStage:Stage): Void
Init the focus manager, it will only start works when it is inited. By default, it will be inited when a component is added to stage automatically.
function isTraversalAsDefault(): Bool
Returns whether or not to use default value for traversal enabled. @see #isTraversalEnabled() @see #setDefaultTraversalEnabled()
function isTraversalEnabled(): Bool
Returns traversal by keys pressing is enabled or not.
If isTraversalAsDefault() returns true, this will returns isDefaultTraversalEnabled
If this method called, TAB... keys will or not effect the focus traverse with this focus system.
And component will or not fire any Key events when there are focused and key pressed.
@see #isTraversalAsDefault() @see #setDefaultTraversalEnabled()function isTraversing(): Bool
Returns if the focus is traversing by keys.
Once when focus traversed by FocusTraversalKeys this is turned on, true will be returned. Once when Mouse is down, this will be turned off, false will be returned. @see #getDefaultFocusTraversalKeys() @see Component#getFocusTraversalKeys()
| returns | true if the focus is traversing by FocusTraversalKeys, otherwise returns false. |
function setActiveWindow(newActiveWindow:JWindow): Void
Sets the active Window. The active Window is always either the focused Window, or the first Window that is an owner of the focused Window.
This method does not actually change the active Window .
It merely stores the value to be
subsequently returned by getActiveWindow(). Use
Component.requestFocus() or
Component.requestFocusInWindow() or
JWindow.setActive()to change the active
Window.
@see #getActiveWindow() @see Component#requestFocus() @see Component#requestFocusInWindow() @see JWindow#setActive()
| activeWindow | the active Window |
function setDefaultFocusTraversalPolicy(newDefaultPolicy:FocusTraversalPolicy): Void
Sets the default FocusTraversalPolicy. Top-level components use this value on their creation to initialize their own focus traversal policy by explicit call to Container.setFocusTraversalPolicy. Note: this call doesn't affect already created components as they have their policy initialized. Only new components will use this policy as their default policy.
@see #getDefaultFocusTraversalPolicy() @see Container#setFocusTraversalPolicy() @see Container#getFocusTraversalPolicy()
| defaultPolicy | the new, default FocusTraversalPolicy, if it is null, nothing will be done |
function setFocusOwner(newFocusOwner:Component): Void
Sets the focus owner. The operation will be cancelled if the Component is not focusable.
This method does not actually set the focus to the specified Component.
It merely stores the value to be subsequently returned by
getFocusOwner(). Use Component.requestFocus()
or Component.requestFocusInWindow() to change the focus
owner.
@see #getFocusOwner() @see Component#requestFocus() @see Component#isFocusable()
| focusOwner | the focus owner |
function setTraversalAsDefault(b:Bool): Void
Sets whether or not to use default value for traversal enabled. @see #isTraversalEnabled() @see #setDefaultTraversalEnabled()
function setTraversalEnabled(b:Bool): Void
Disables or enables the traversal by keys pressing.
This will call setTraversalAsDefault(false)
If this method called, TAB... keys will or not effect the focus traverse with this focus system.
And component will or not fire any Key events when there are focused and key pressed.
@see #setTraversalAsDefault() @see #setDefaultTraversalEnabled()function setTraversing(b:Bool): Void
Sets if the focus is traversing by keys.
By default, the traversing property will only be set true when TRAVERSAL_KEYS down. If your component need view focus rect, you should set it to true when your component's managed key down. @see #isTraversing()
| b | true tag traversing to be true, false tag traversing to be false |
