Detailed Description

Base namespace class.

The NET API is an implementation of the NET Window Manager Specification.

This class is the base class for the NETRootInfo and NETWinInfo classes, which are used to retrieve and modify the properties of windows. To keep the namespace relatively clean, all enums are defined here.

DesktopLayoutCorner

enum NET::DesktopLayoutCorner

Definition at line 867 of file netwm_def.h.

Direction

enum NET::Direction

When a client wants the Window Manager to start a WMMoveResize, it should specify one of:

• TopLeft
• Top
• TopRight
• Right

• Move (for movement only)
• KeyboardSize (resizing via keyboard)
• KeyboardMove (movement via keyboard)

Definition at line 602 of file netwm_def.h.

MappingState

enum NET::MappingState

Client window mapping state.

The class automatically watches the mapping state of the client windows, and uses the mapping state to determine how to set/change different properties. Note that this is very lowlevel and you most probably don't want to use this state.

Enumerator
Visible	indicates the client window is visible to the user.
Withdrawn	indicates that neither the client window nor its icon is visible.
Iconic	indicates that the client window is not visible, but its icon is. This can be when the window is minimized or when it's on a different virtual desktop. See also NET::Hidden.

Protocol

enum NET::Protocol

Protocols supported by the client.

See ICCCM 4.1.2.7.

See also

Protocols

Since

5.3

Enumerator
TakeFocusProtocol	WM_TAKE_FOCUS.
DeleteWindowProtocol	WM_DELETE_WINDOW.
PingProtocol	_NET_WM_PING from EWMH
SyncRequestProtocol	_NET_WM_SYNC_REQUEST from EWMH
ContextHelpProtocol	_NET_WM_CONTEXT_HELP, NON STANDARD!

Definition at line 881 of file netwm_def.h.

RequestSource

enum NET::RequestSource

Source of the request.

Enumerator
FromUnknown	indicates that the source of the request is unknown
FromApplication	indicates that the request comes from a normal application
FromTool	indicated that the request comes from pager or similar tool

Definition at line 841 of file netwm_def.h.

Role

enum NET::Role

Application role.

This is used internally to determine how several action should be performed (if at all).

Enumerator
Client	indicates that the application is a client application.
WindowManager	indicates that the application is a window manager application.

Definition at line 342 of file netwm_def.h.

State

enum NET::State

Window state.

To set the state of a window, you'll typically do something like:

KX11Extras::setState( winId(), NET::SkipTaskbar | NET::SkipPager | NET::SkipSwitcher );

for example to not show the window on the taskbar, desktop pager, or window switcher. winId() is a function of QWidget()

Note that KeepAbove (StaysOnTop) and KeepBelow are meant as user preference and applications should avoid setting these states themselves.

States

Enumerator
Modal	indicates that this is a modal dialog box. The WM_TRANSIENT_FOR hint MUST be set to indicate which window the dialog is a modal for, or set to the root window if the dialog is a modal for its window group.
Sticky	indicates that the Window Manager SHOULD keep the window's position fixed on the screen, even when the virtual desktop scrolls. Note that this is different from being kept on all desktops.
MaxVert	indicates that the window is vertically maximized.
MaxHoriz	indicates that the window is horizontally maximized.
Max	convenience value. Equal to MaxVert | MaxHoriz.
Shaded	indicates that the window is shaded (rolled-up).
SkipTaskbar	indicates that a window should not be included on a taskbar.
KeepAbove	indicates that a window should on top of most windows (but below fullscreen windows).
SkipPager	indicates that a window should not be included on a pager.

FullScreen	indicates that a window should fill the entire screen and have no window decorations.
KeepBelow	indicates that a window should be below most windows (but above any desktop windows).
DemandsAttention	there was an attempt to activate this window, but the window manager prevented this. E.g. taskbar should mark such window specially to bring user's attention to this window. Only the window manager is allowed to change it.
SkipSwitcher	indicates that a window should not be included on a switcher. Since 5.45
Focused	indicates that a client should render as though it has focus Only the window manager is allowed to change it. Since 5.58

Toolbar	indicates a toolbar window
Menu	indicates a pinnable (torn-off) menu window
Dialog	indicates that this is a dialog window
Override	Deprecated has unclear meaning and is KDE-only

Member Function Documentation

timestampCompare()

int NET::timestampCompare ( unsigned long time1, unsigned long time2 )

timestampDiff()

int NET::timestampDiff ( unsigned long time1, unsigned long time2 )

static

Returns a difference of two X timestamps, time2 - time1, where time2 must be later than time1, as returned by timestampCompare().

Definition at line 4930 of file netwm.cpp.

typeMatchesMask()

bool NET::typeMatchesMask ( WindowType type, WindowTypes mask )
