Detailed Description

This class contains the main X event loop, as supplied by Qt. The events are either used by member functions or are dispatched to the corresponding Handler object.
Basic initialization takes place here as well.

Constructor & Destructor Documentation

Manager::Manager ( int argc,

char ** argv

)

The arguments argc and argv are not used here, but are passed on to QApplication.
This allows us to use them later, if and when we have a use for them.
Some arguments may be swallowed by Qt, though.
Here is the call graph for this function:

Manager::~Manager ( )

Member Function Documentation

Strut* Manager::getMasterStrut ( ) [inline]

bool Manager::handleButtonPressEvent ( XEvent * ) [private]

bool Manager::handleButtonReleaseEvent ( XEvent * ) [private]

bool Manager::handleClientMessageEvent ( XEvent * ) [private]

bool Manager::handleColormapNotifyEvent ( XEvent * ) [private]

bool Manager::handleConfigureRequestEvent ( XEvent * ev ) [private]

If the window already is a client, i.e. is found in the Client map, the handling of this event is done in the corresponding Handler object. Otherwise the request is delegated back to the window so it can use it.
In any case returns true.

bool Manager::handleDefaultEvent ( XEvent * ) [private]

bool Manager::handleDestroyNotifyEvent ( XEvent * ) [private]

bool Manager::handleEnterNotifyEvent ( XEvent * ) [private]

bool Manager::handleExposeEvent ( XEvent * ) [private]

bool Manager::handleFocusInEvent ( XEvent * ) [private]

bool Manager::handleFocusOutEvent ( XEvent * ) [private]

bool Manager::handleKeyPressEvent ( XEvent * ) [private]

bool Manager::handleLeaveNotifyEvent ( XEvent * ) [private]

bool Manager::handleMapRequestEvent ( XEvent * ev ) [private]

If the requesting window already is a client, the corresponding Handler object will handle it. Otherwise a new Handler object is created and added to the Client map.
Returns true in both cases.

Todo:
I am not really happy with this one, will have to be rechecked later.

bool Manager::handleMotionNotifyEvent ( XEvent * ) [private]

bool Manager::handlePropertyNotifyEvent ( XEvent * ev ) [private]

If it is a known client as found in the Client map, the event is handled by the corresponding Handler object. In this case true will be returned.
Otherwise nothing is done and false is returned.

bool Manager::handleUnmapNotifyEvent ( XEvent * ) [private]

void Manager::quitNicely ( )

void Manager::restart ( )

void Manager::scanWindows ( ) [private]

Function to scan for existing windows at startup. Existing windows will be mapped as clients and will be shown if necessary.

void Manager::setExtendedNetDesktopGeometry ( ) [private]

void Manager::setExtendedNetDesktopViewport ( ) [private]

void Manager::setExtendedNetSupported ( ) [private]

void Manager::setExtendedWMHint ( Window ,

int ,

long

)

void Manager::setExtendedWMHintString ( Window ,

int ,

char *

) [private]

void Manager::setupDisplay ( ) [private]

The name of this member is somehow misleading. It is really used to set up the basic members we need to manage windows. It also sets up a decent cursor - I think a window manager should do this: I for one don't like that ugly big fat X shaped default cursor.
This is the place where the atoms we will be using are set up.
Todo:
I don't like the way atoms are handled at all.

void Manager::setupSignalHandlers ( ) [private]

Here is the call graph for this function:

bool Manager::x11EventFilter ( XEvent * ev ) [protected]

This is where the heart beats.
x11EventFilter is reimplemented from QApplication. It is merely a dispatcher to enable more specialized functions to take a closer look at every XEvent. It is a boolean function, to tell QApplication if we have eaten this event ourselfes or expect Qt to do something about it.
Returns true if we used it, false otherwise.
