Direct Known Subclasses:

FileuploadDlg, MessageboxDlg

public class Window
extends XulElement
implements Window, Framable, org.zkoss.zk.ui.IdSpace

A window.

Unlike other elements, each Window is an independent ID space (by implementing IdSpace). It means a window and all its descendants forms a ID space and the ID of each of them is unique in this space. You could retrieve any of them in this space by calling AbstractComponent.getFellow(java.lang.String).

If a window X is a descendant of another window Y, X's descendants are not visible in Y's space. To retrieve a descendant, say Z, of X, you have to invoke Y.getFellow('X').getFellow('Z').

Events:
onMove, onOpen, onMaximize, onMinimize, and onClose.
Note: to have better performance, onOpen is sent only if a non-deferrable event listener is registered (see Deferrable).

onMaximize and onMinimize are supported. (since 3.5.0)

onClose is sent when the close button is pressed (if isClosable() is true). The window has to detach or hide the window. By default, onClose() detaches the window. To prevent it from detached, you have to call Event.stopPropagation() to prevent onClose() is called.

On the other hand, onOpen is sent when a popup window (i.e., getMode() is popup) is closed due to user's activity (such as press ESC). This event is only a notification. In other words, the popup is hidden before the event is sent to the server. The application cannot prevent the window from being hidden.

Default getZclass(): z-window-getMode().(since 3.5.0)

Field Detail

EMBEDDED

public static final int EMBEDDED

Embeds the window as normal component.

See Also:

Constant Field Values

MODAL

public static final int MODAL

Makes the window as a modal dialog. once doModal() is called, the execution of the event processing thread is suspended until one of the following occurs.

1. setMode(java.lang.String) is called with a mode other than MODAL.
2. Either doOverlapped(), doPopup(), doEmbedded(), or doHighlighted() is called.
3. setVisible(boolean) is called with false.
4. The window is detached from the window.

Note: In the last two cases, the mode becomes OVERLAPPED. In other words, one might say a modal window is a special overlapped window.

See Also:

HIGHLIGHTED, Constant Field Values

OVERLAPPED

public static final int OVERLAPPED

Makes the window as overlapped other components.

See Also:

Constant Field Values

POPUP

public static final int POPUP

Makes the window as popup. It is similar to OVERLAPPED, except it is auto hidden when user clicks outside of the window.

See Also:

Constant Field Values

HIGHLIGHTED

public static final int HIGHLIGHTED

Makes the window as highlighted. Its visual effect is the same as MODAL. However, from the server side's viewpoint, it is similar to OVERLAPPED. The execution won't be suspended when doHighlighted() is called.

Constructor Detail

Window

public Window()

Window

public Window(String title,
              String border,
              boolean closable)

Parameters:

title - the window title (see setTitle(java.lang.String)).

Method Detail

isMaximized

public boolean isMaximized()

Returns whether the window is maximized.

Specified by:

isMaximized in interface Window

Specified by:

isMaximized in interface Framable

Since:

3.5.0

setMaximized

public void setMaximized(boolean maximized)

Sets whether the window is maximized, and then the size of the window will depend on it to show a appropriate size. In other words, if true, the size of the window will count on the size of its offset parent node whose position is absolute (by not inEmbedded()) or its parent node. Otherwise, its size will be original size. Note that the maximized effect will run at client's sizing phase not initial phase.

Default: false.

Specified by:

setMaximized in interface Window

Throws:

org.zkoss.zk.ui.UiException - if isMaximizable() is false.

Since:

3.5.0

isMaximizable

public boolean isMaximizable()

Returns whether to display the maximizing button and allow the user to maximize the window.

Default: false.

Specified by:

isMaximizable in interface Window

Specified by:

isMaximizable in interface Framable

Since:

3.5.0

setMaximizable

public void setMaximizable(boolean maximizable)

Sets whether to display the maximizing button and allow the user to maximize the window, when a window is maximized, the button will automatically change to a restore button with the appropriate behavior already built-in that will restore the window to its previous size.

Default: false.

Note: the maximize button won't be displayed if no title or caption at all.

Specified by:

setMaximizable in interface Window

Since:

3.5.0

isMinimized

public boolean isMinimized()

Returns whether the window is minimized.

Default: false.

Specified by:

isMinimized in interface Window

Since:

3.5.0

setMinimized

public void setMinimized(boolean minimized)

Sets whether the window is minimized.

Default: false.

Specified by:

setMinimized in interface Window

Throws:

org.zkoss.zk.ui.UiException - if isMinimizable() is false.

isMinimizable

public boolean isMinimizable()

Returns whether to display the minimizing button and allow the user to minimize the window.

Default: false.

Specified by:

isMinimizable in interface Window

Specified by:

isMinimizable in interface Framable

Since:

3.5.0

setMinimizable

public void setMinimizable(boolean minimizable)

Sets whether to display the minimizing button and allow the user to minimize the window. Note that this button provides no implementation -- the behavior of minimizing a window is implementation-specific, so the MinimizeEvent event must be handled and a custom minimize behavior implemented for this option to be useful.

Default: false.

Note: the maximize button won't be displayed if no title or caption at all.

Specified by:

setMinimizable in interface Window

Since:

3.5.0

See Also:

MinimizeEvent

setMinheight

getBorder in interface Window

setBorder

public void setBorder(String border)

Sets the border (either none or normal).

border - the border. If null, "0" or "false", "none" is assumed. If "true", "normal" is assumed (since 5.0.8).

setBorder

public void setBorder(boolean border)

Enables or disables the border.

Parameters:

border - whether to have a border. If true is specified, it is the same as setBorder("normal").

Since:

5.0.8

getTitle

public String getTitle()

Returns the title. Besides this attribute, you could use Caption to define a more sophiscated caption (aka., title).

If a window has a caption whose label (LabelElement.getLabel()) is not empty, then this attribute is ignored.

Default: empty.

Specified by:

getTitle in interface Window

Specified by:

getTitle in interface Framable

setTitle

public void setTitle(String title)

Sets the title.

Specified by:

setTitle in interface Window

getMode

public String getMode()

Returns the current mode. One of "modal", "embedded", "overlapped", "popup", and "highlighted".

Specified by:

getMode in interface Window

setMode

public void setMode(String name)
             throws InterruptedException

Sets the mode to overlapped, popup, modal, embedded or highlighted.

Notice: Events.ON_MODAL is posted if you specify "modal" to this method. Unlike doModal(), Events.ON_MODAL is posted, so the window will become modal later (since 3.0.4). In other words, setMode("modal") never suspends the execution of the current thread. On the other hand, doModal() will suspends the execution if executed in an event listener, or throws an exception if not executed in an event listener.

Refer to Overlapped, Popup, Modal, Highlighted and Embedded for more information.

If the event processing thread is disabled (it is the default), InterruptedException won't be thrown.

Specified by:

setMode in interface Window

Parameters:

name - the mode which could be one of "embedded", "overlapped", "popup", "modal", "highlighted". Note: it cannot be "modal". Use doModal() instead.

Throws:

InterruptedException - thrown if "modal" is specified the event thread is enabled (disabled by default), and one of the following conditions occurs: 1) the desktop or the Web application is being destroyed, or 2) DesktopCtrl.ceaseSuspendedThread(org.zkoss.zk.ui.sys.EventProcessingThread, java.lang.String). To tell the difference, check the getMessage method of InterruptedException.

setMode

public void setMode(int mode)
             throws InterruptedException

Sets the mode to overlapped, popup, modal, embedded or highlighted.

Specified by:

setMode in interface Window

Throws:

InterruptedException

See Also:

setMode(String)

inModal

public boolean inModal()

Returns whether this is a modal dialog.

Specified by:

inModal in interface Window

inEmbedded

public boolean inEmbedded()

Returns whether this is embedded with other components (Default).

Specified by:

inEmbedded in interface Window

See Also:

doEmbedded()

inOverlapped

public boolean inOverlapped()

Returns whether this is a overlapped window.

Specified by:

inOverlapped in interface Window

inPopup

public boolean inPopup()

Returns whether this is a popup window.

Specified by:

inPopup in interface Window

inHighlighted

public boolean inHighlighted()

Returns whether this is a highlighted window.

Specified by:

inHighlighted in interface Window

doModal

public void doModal()
             throws InterruptedException,
                    org.zkoss.zk.ui.SuspendNotAllowedException

Makes this window as a modal dialog. It will automatically center the window (ignoring HtmlBasedComponent.getLeft() and HtmlBasedComponent.getTop()).

Notice: though both setMode("modal") and doModal() both causes the window to become modal, they are a bit different. doModal causes the event listener to suspend immediately, while setMode("modal") posts an event (Events.ON_MODAL). That is, setMode(java.lang.String) won't suspend the execution immediately, but doModal() will. doModal() can be called only in an event listener, while setMode(java.lang.String) can be called anytime.

Specified by:

doModal in interface Window

Throws:

org.zkoss.zk.ui.SuspendNotAllowedException - if 1) not in an event listener;
2) the event thread is disabled.
3) there are too many suspended processing thread than the deployer allows. By default, there is no limit of # of suspended threads.

InterruptedException - thrown if the desktop or the Web application is being destroyed, or DesktopCtrl.ceaseSuspendedThread(org.zkoss.zk.ui.sys.EventProcessingThread, java.lang.String). To tell the difference, check the getMessage method of InterruptedException.

Since:

3.0.4

doOverlapped

public void doOverlapped()

Makes this window as overlapped with other components.

Specified by:

doOverlapped in interface Window

doPopup

public void doPopup()

Makes this window as popup, which is overlapped with other component and auto-hiden when user clicks outside of the window.

Specified by:

doPopup in interface Window

doHighlighted

public void doHighlighted()

Makes this window as highlited. The visual effect is the similar to the modal window, but, like overlapped, it doesn't suspend (block) the execution at the server. In other words, it is more like an overlapped window from the server side's viewpoint.

Specified by:

doHighlighted in interface Window

doEmbedded

public void doEmbedded()

Makes this window as embeded with other components (Default).

Specified by:

doEmbedded in interface Window

isClosable

public boolean isClosable()

Returns whether to show a close button on the title bar.

Specified by:

isClosable in interface Window

Specified by:

isClosable in interface Framable

setClosable

public void setClosable(boolean closable)

Sets whether to show a close button on the title bar. If closable, a button is displayed and the onClose event is sent if an user clicks the button.

Default: false.

You can intercept the default behavior by either overriding onClose(), or listening the onClose event.

Note: the close button won't be displayed if no title or caption at all.

Specified by:

setClosable in interface Window

public boolean isSizable()

Returns whether the window is sizable.

Specified by:

isSizable in interface Window

setSizable

public void setSizable(boolean sizable)

Sets whether the window is sizable. If true, an user can drag the border to change the window width.

Default: false.

Specified by:

setSizable in interface Window

isShadow

Since:

3.6.0

setShadow

public void setShadow(boolean shadow)

Sets whether to show the shadow of an overlapped/popup/modal window. It is meaningless if it is an embedded window.

Default: true.

Since:

3.6.0

getPosition

public String getPosition()

Returns how to position the window at the client screen. It is meaningless if the embedded mode is used.

Default: null which depends on getMode(): If overlapped or popup, HtmlBasedComponent.setLeft(java.lang.String) and HtmlBasedComponent.setTop(java.lang.String) are assumed. If modal or highlighted, it is centered.

Specified by:

getPosition in interface Window

setPosition

public void setPosition(String pos)

Sets how to position the window at the client screen. It is meaningless if the embedded mode is used.

Specified by:

setPosition in interface Window

Parameters:

pos - how to position. It can be null (the default), or a combination of the following values (by separating with comma).

center

Position the window at the center. HtmlBasedComponent.setTop(java.lang.String) and HtmlBasedComponent.setLeft(java.lang.String) are both ignored.

nocenter

Not to position the window at the center. A modal window, by default, will be position at the center. By specifying this value could prevent it and the real position depends on HtmlBasedComponent.setTop(java.lang.String) and HtmlBasedComponent.setLeft(java.lang.String) (since 5.0.4)

left

Position the window at the left edge. HtmlBasedComponent.setLeft(java.lang.String) is ignored.

Position the window at the right edge. HtmlBasedComponent.setLeft(java.lang.String) is ignored.

top

Position the window at the top edge. HtmlBasedComponent.setTop(java.lang.String) is ignored.

bottom

Position the window at the bottom edge. HtmlBasedComponent.setTop(java.lang.String) is ignored.

parent

Position the window relative to its parent. That is, the left and top (HtmlBasedComponent.getTop() and HtmlBasedComponent.getLeft()) is an offset to his parent's let-top corner. (since 3.0.2)

For example, "left,center" means to position it at the center of the left edge.

onClose

public void onClose()

Process the onClose event sent when the close button is pressed.

Default: detach itself.

onModal

public void onModal()
             throws InterruptedException

Process the onModal event by making itself a modal window.

setVisible

public boolean setVisible(boolean visible)

Changes the visibility of the window.

Note if you turned on the event thread:
If a modal dialog becomes invisible, the modal state will be ended automatically. In other words, the mode (getMode()) will become OVERLAPPED and the suspending thread is resumed. In other words, the modal window (MODAL) can not be invisible (while a window in other modes could be invisible).

However, if the event thread is not enabled (default), there is no such limitation. In other words, it remains the same mode when becoming invisible.
