Detailed Description

The WindowManager class describes an object that manages creation and lifetime of Window objects.

The WindowManager is the means by which Window objects are created and destroyed. For each sub-class of Window that is to be created, there must exist a WindowFactory object which is registered with the WindowFactoryManager. Additionally, the WindowManager tracks every Window object created, and can be used to access those Window objects by name.

Member Typedef Documentation

typedef bool CEGUI::WindowManager::PropertyCallback(Window *window, String &propname, String &propvalue, void *userdata)

Function type that is used as a callback when loading layouts from XML; the function is called for each Property element encountered.

Parameters
windowWindow object that the property is to be applied to.
propnameString holding the name of the property that is being set.
propvalueString holding the new value that will be applied to the property specified by /a propname.
userdataSome client code supplied data.
Returns
  • true if the property should be set.
  • false if the property should not be set,

Constructor & Destructor Documentation

CEGUI::WindowManager::WindowManager ( void  )

Constructs a new WindowManager object.

NB: Client code should not create WindowManager objects - they are of limited use to you! The intended pattern of access is to get a pointer to the GUI system's WindowManager via the System object, and use that.

CEGUI::WindowManager::~WindowManager ( void  )

Destructor for WindowManager objects.

This will properly destry all remaining Window objects. Note that WindowFactory objects will not be destroyed (since they are owned by whoever created them).

Member Function Documentation

void CEGUI::WindowManager::cleanDeadPool ( void  )

Permanently destroys any windows placed in the dead pool.

Note
It is probably not a good idea to call this from a Window based event handler if the specific window has been or is being destroyed.
Returns
Nothing.
Window* CEGUI::WindowManager::createWindow ( const String type,
const String name = "" 
)

Creates a new Window object of the specified type, and gives it the specified unique name.

Parameters
typeString that describes the type of Window to be created. A valid WindowFactory for the specified type must be registered.
nameString that holds a unique name that is to be given to the new window. If this string is empty (""), a name will be generated for the window.
Returns
Pointer to the newly created Window object.
Exceptions
InvalidRequestExceptionWindowManager is locked and no Windows may be created.
AlreadyExistsExceptionA Window object with the name name already exists.
UnknownObjectExceptionNo WindowFactory is registered for type Window objects.
GenericExceptionSome other error occurred (Exception message has details).
void CEGUI::WindowManager::DEBUG_dumpWindowNames ( String  zone)

Outputs the names of ALL existing windows to log (DEBUG function).

Parameters
zoneHelper string that can specify where the name dump was made (e.g. "BEFORE FRAME DELETION").
Returns
Nothing.
void CEGUI::WindowManager::destroyAllWindows ( void  )

Destroys all Window objects within the system.

Returns
Nothing.
Exceptions
InvalidRequestExceptionThrown if the WindowFactory for any Window object type has been removed.
void CEGUI::WindowManager::destroyWindow ( Window window)

Destroy the specified Window object.

Parameters
windowPointer to the Window object to be destroyed. If the window is null, or is not recognised, nothing happens.
Returns
Nothing
Exceptions
InvalidRequestExceptionCan be thrown if the WindowFactory for window's object type was removed.
void CEGUI::WindowManager::destroyWindow ( const String window)

Destroy the specified Window object.

Parameters
windowString containing the name of the Window object to be destroyed. If window is not recognised, nothing happens.
Returns
Nothing.
Exceptions
InvalidRequestExceptionCan be thrown if the WindowFactory for window's object type was removed.
static const String& CEGUI::WindowManager::getDefaultResourceGroup ( )
inlinestatic

Returns the default resource group currently set for layouts.

Returns
String describing the default resource group identifier that will be used when loading layouts.
Window* CEGUI::WindowManager::getWindow ( const String name) const

Return a pointer to the specified Window object.

Parameters
nameString holding the name of the Window object to be returned.
Returns
Pointer to the Window object with the name name.
Exceptions
UnknownObjectExceptionNo Window object with a name matching name was found.
bool CEGUI::WindowManager::isDeadPoolEmpty ( void  ) const

Return whether the window dead pool is empty.

Returns
  • true if there are no windows in the dead pool.
  • false if the dead pool contains >=1 window awaiting destruction.
bool CEGUI::WindowManager::isLocked ( ) const

Returns whether WindowManager is currently in the locked state.

While WindowManager is in the locked state all attempts to create a
Window of any type will fail with an InvalidRequestException being
thrown.  Calls to lock/unlock are recursive; if multiple calls to lock
are made, WindowManager is only unlocked after a matching number of
calls to unlock.
Returns
  • true to indicate WindowManager is locked and that any attempt to create Window objects will fail.
  • false to indicate WindowManager is unlocked and that Window objects may be created as normal.
bool CEGUI::WindowManager::isWindowPresent ( const String name) const

Examines the list of Window objects to see if one exists with the given name.

Parameters
nameString holding the name of the Window object to look for.
Returns
true if a Window object was found with a name matching name. false if no matching Window object was found.
Window* CEGUI::WindowManager::loadWindowLayout ( const String filename,
const String name_prefix = "",
const String resourceGroup = "",
PropertyCallback callback = 0,
void *  userdata = 0 
)

Creates a set of windows (a Gui layout) from the information in the specified XML file.

Parameters
filenameString object holding the filename of the XML file to be processed.
name_prefixString object holding the prefix that is to be used when creating the windows in the layout file, this function allows a layout to be loaded multiple times without having name clashes. Note that if you use this facility, then all windows defined within the layout must have names assigned; you currently can not use this feature in combination with automatically generated window names.
resourceGroupResource group identifier to be passed to the resource provider when loading the layout file.
callbackPropertyCallback function to be called for each Property element loaded from the layout. This is called prior to the property value being applied to the window enabling client code manipulation of properties.
userdataClient code data pointer passed to the PropertyCallback function.
Returns
Pointer to the root Window object defined in the layout.
Exceptions
FileIOExceptionthrown if something goes wrong while processing the file filename.
InvalidRequestExceptionthrown if filename appears to be invalid.
void CEGUI::WindowManager::lock ( )

Put WindowManager into the locked state.

While WindowManager is in the locked state all attempts to create a
Window of any type will fail with an InvalidRequestException being
thrown.  Calls to lock/unlock are recursive; if multiple calls to lock
are made, WindowManager is only unlocked after a matching number of
calls to unlock.
Note
This is primarily intended for internal use within the system.
void CEGUI::WindowManager::renameWindow ( const String window,
const String new_name 
)

Rename a window.

Parameters
windowString holding the current name of the window to be renamed.
new_nameString holding the new name for the window
Exceptions
UnknownObjectExceptionthrown if window is not known in the system.
AlreadyExistsExceptionthrown if a Window named new_name already exists.
void CEGUI::WindowManager::renameWindow ( Window window,
const String new_name 
)

Rename a window.

Parameters
windowPointer to the window to be renamed.
new_nameString holding the new name for the window
Exceptions
AlreadyExistsExceptionthrown if a Window named new_name already exists.
static void CEGUI::WindowManager::setDefaultResourceGroup ( const String resourceGroup)
inlinestatic

Sets the default resource group to be used when loading layouts.

Parameters
resourceGroupString describing the default resource group identifier to be used.
Returns
Nothing.
void CEGUI::WindowManager::unlock ( )

Put WindowManager into the unlocked state.

While WindowManager is in the locked state all attempts to create a
Window of any type will fail with an InvalidRequestException being
thrown.  Calls to lock/unlock are recursive; if multiple calls to lock
are made, WindowManager is only unlocked after a matching number of
calls to unlock.
Note
This is primarily intended for internal use within the system.
void CEGUI::WindowManager::writeWindowLayoutToStream ( const Window window,
OutStream out_stream,
bool  writeParent = false 
) const

Writes a full XML window layout, starting at the given Window to the given OutStream.

Parameters
