Detailed Description

The class TWinModule provides information about the state of the window manager as required by windowmanager modules.

It informs a module about all currently managed windows and changes to them (via TQt signals).

TWinModule uses NETRootInfo internally. Modules written with this class will work fine under any window manager that implements the NET_WM protocol.

There are no methods to manipulate windows. Those are defined in the classes KWin, NETWinInfo and NETRootInfo.

Base class for TDE Window Manager modules.

(

)

const

Returns the number of virtual desktops.

Returns

the number of virtual desktops

numberOfDesktopsChanged

void TWinModule::numberOfDesktopsChanged ( int  num )

signal

The number of desktops changed.

Parameters

num	the new number of desktops

numberOfViewports()

		const TQString &	name
	)

Sets the name of the specified desktop.

Parameters

desktop	the number of the desktop
name	the new name for the desktop

showingDesktop()

stackingOrder()

const TQValueList< WId > & TWinModule::stackingOrder

(

)

const

Returns the list of all toplevel windows currently managed by the window manager in the current stacking order (from lower to higher).

May be useful for pagers.

Returns

the list of all toplevel windows in stacking order

stackingOrderChanged

void TWinModule::stackingOrderChanged ( )

signal

Emitted when the stacking order of the window changed.

The new order can be obtained with stackingOrder().

strutChanged

void TWinModule::strutChanged ( )

signal

Something changed with the struts, may or may not have changed the work area.

Usually just using the workAreaChanged() signal is sufficient.

systemTrayWindowAdded

void TWinModule::windowChanged ( WId  id, const unsigned long *  properties  )

signal

The window changed.

The properties parameter contains the NET properties that were modified (see netwm_def.h). First element are NET::Property values, second element are NET::Property2 values (i.e. the format is the same like for the NETWinInfo class constructor).

Parameters

id	the id of the window
properties	the properties that were modified

windowChanged [3/3]

void TWinModule::windowChanged ( WId  id, unsigned int  properties  )

signal

Deprecated:

The window changed.

id	the id of the window
properties	the properties that were modified

windowRemoved

void TWinModule::windowRemoved ( WId  id )

signal

A window has been removed.

Parameters

id	the id of the window that has been removed

windows()

const TQValueList< WId > & TWinModule::windows

(

)

const

Returns the list of all toplevel windows currently managed by the window manager in the order of creation.

Please do not rely on indexes of this list: Whenever you enter TQt's event loop in your application, it may happen that entries are removed or added. Your module should perhaps work on a copy of this list and verify a window with hasWId() before any operations.

Iteration over this list can be done easily with

TQValueList<WId>::ConstIterator it;
for ( it = module->windows().begin();
      it != modules->windows().end(); ++it ) {
   ... do something here,  (*it) is the current WId.
     }

the list of all toplevel windows

TQRect TWinModule::workArea	(	const TQValueList< WId > &	excludes,
		int	desktop = -1

Excludes struts of clients in the exclude List.

Parameters

excludes	the list of clients whose struts will be excluded
desktop	the number of the desktop to check, -1 for the current desktop

Returns

the size and position of the desktop

workArea() [2/2]

TQRect TWinModule::workArea

(

int

desktop = - 1

)

const

Returns the workarea for the specified desktop, or the current work area if no desktop has been specified.

Parameters

desktop

the number of the desktop to check, -1 for the current desktop
