Detailed Description
Common API for root window properties/protocols.
The NETRootInfo class provides a common API for clients and window managers to set/read/change properties on the root window as defined by the NET Window Manager Specification..

Constructor & Destructor Documentation
| NETRootInfo::NETRootInfo | ( | Display * | display, |
| Window | supportWindow, | ||
| const char * | wmName, | ||
| const unsigned long | properties[], | ||
| int | properties_size, | ||
| int | screen = -1, |
||
| bool | doActivate = true |
||
| ) |
Window Managers should use this constructor to create a NETRootInfo object, which will be used to set/update information stored on the rootWindow.
The application role is automatically set to WindowManager when using this constructor.
- Parameters
-
display An X11 Display struct. supportWindow The Window id of the supportWindow. The supportWindow must be created by the window manager as a child of the rootWindow. The supportWindow must not be destroyed until the Window Manager exits. wmName A string which should be the window manager's name (ie. "KWin" or "Blackbox"). properties An array of elements listing all properties and protocols the window manager supports. The elements contain OR'ed values of constants from the NET base class, in the following order: [0]= NET::Property, [1]= NET::WindowTypeMask (not NET::WindowType!), [2]= NET::State, [3]= NET::Property2, [4]= NET::Action. In future versions, the list may be extended. In case you pass less elements, the missing ones will be replaced with default values. properties_size The number of elements in the properties array. screen For Window Managers that support multiple screen (ie. "multiheaded") displays, the screen number may be explicitly defined. If this argument is omitted, the default screen will be used. doActivate true to activate the window
| NETRootInfo::NETRootInfo | ( | Display * | display, |
| const unsigned long | properties[], | ||
| int | properties_size, | ||
| int | screen = -1, |
||
| bool | doActivate = true |
||
| ) |
Clients should use this constructor to create a NETRootInfo object, which will be used to query information set on the root window.
The application role is automatically set to Client when using this constructor.
- Parameters
-
display An X11 Display struct. properties An array of elements listing all protocols the client is interested in. The elements contain OR'ed values of constants from the NET base class, in the following order: [0]= NET::Property, [1]= NET::Property2. properties_size The number of elements in the properties array. screen For Clients that support multiple screen (ie. "multiheaded") displays, the screen number may be explicitly defined. If this argument is omitted, the default screen will be used. doActivate true to call activate() to do an initial data read/update of the query information.
| NETRootInfo::NETRootInfo | ( | Display * | display, |
| unsigned long | properties, | ||
| int | screen = -1, |
||
| bool | doActivate = true |
||
| ) |
This constructor differs from the above one only in the way it accepts the list of supported properties.
The properties argument is equivalent to the first element of the properties array in the above constructor, and therefore you cannot read all root window properties using it.
| NETRootInfo::NETRootInfo | ( | const NETRootInfo & | rootinfo | ) |
Creates a shared copy of the specified NETRootInfo object.
- Parameters
-
rootinfo the NETRootInfo object to copy
|
virtual |
Destroys the NETRootInfo object.
Member Function Documentation
| void NETRootInfo::activate | ( | ) |
Window Managers must call this after creating the NETRootInfo object, and before using any other method in the class.
This method sets initial data on the root window and does other post-construction duties.
Clients must also call this after creating the object to do an initial data read/update.

| ) |
This function takes the passed XEvent and returns an OR'ed list of NETRootInfo properties that have changed in the properties argument.
The new information will be read immediately by the class. The elements of the properties argument are as they would be passed to the constructor, if the array is not large enough, changed properties that don't fit in it won't be listed there (they'll be updated in the class though).
- Parameters

event the event properties properties that changed properties_size size of the passed properties array

This function takes the passed XEvent and returns an OR'ed list of NETRootInfo properties that have changed.
The new information will be read immediately by the class. This overloaded version returns only a single mask, and therefore cannot check state of all properties like the other variant.
- Parameters
-
event the event
- Returns
- the properties
