Detailed Description

A session recording class.

The purpose of this class is to collect session data from several QEditor object, to serialize it and to re-create the same session by deserializing the stored data.


Member Function Documentation

int QEditSession::autoUpdateInterval ( ) const
Returns:
The update interval, in milliseconds

A value of zero means the data is NOT automatically updated.

See also:
updateData()
QString QEditSession::fileName ( ) const
Returns:
The file name used as storage

If it is empty then no auto-save is performed.

void QEditSession::loaded ( QEditor e,
const QString &  fn 
)
protectedvirtualslot

Called whenever an editor is loaded with new content.

This handler is responsible for updating file names and time stamps which is needed to avoid data loss upon session restoration

Referenced by addEditor(), removeEditor(), and restore().

void QEditSession::saved ( QEditor e,
const QString &  fn 
)
protectedvirtualslot

Called whenever an editor is saved.

This handler is responsible for updating file names and time stamps which is needed to avoid data loss upon session restoration

Referenced by addEditor(), removeEditor(), and restore().

void QEditSession::setAutoUpdateInterval ( int  ms)
virtualslot

Set the update interval.

If ms is strictly positive then the data will be updated every ms milliseconds

If the session has been given a valid filename, the updated data will automatically be saved to that file.

void QEditSession::setFileName ( const QString &  filename,
bool  r = false 
)
virtualslot

Set the storage destination.

Every time the data is updated, either when the autoupdate timer ticks or when updateData() is called programmatically, it will be written to that file, provided the filename is valid and points to a writeable location.

updateData()
autoUpdateInterval()

void QEditSession::updateData ( )
virtualslot

Updates the data.

Fetches up-to-date session data from the attached editors.

If the session has been given a valid filename the data will automatically be saved.

Note:
This will NOT affect the automatic updates timing
