Member Function Documentation

void dbHelper::maybeChangeTargetLink (  dbFieldLink *   )  [virtual]

Reimplemented in dbAbstractEditHelper.

void dbHelper::maybeDirty (  dbFieldLink *   )  [virtual]

Reimplemented in dbAbstractEditHelper, and OOF_mixRepAbstractCellEditor.

bool oofSingleListener::receiveMsg (  OOFmsgT  msg, unsigned long  senderDefined )  [virtual, inherited]

The default receiveMsg behaviour is to delete yourself when the broadcaster closes. In many user subclasses oofSingleListener is a mixin and you have a class owned elsewhere, not self-deleting. Warning: If a subclass is not self-deleting it MUST override receiveMsg handling of the msg OOFmsg_BroadcasterClosing to prevent runtime error. However it is still important to set mListensTo=0 otherwise when you finally get around to deleting your oofSingleListener, it will try to update a deleted oofBroadcaster and cause a crash. Implements oofReceiver. Reimplemented in dbCloneCleanup, dbRelMaintainer, dbFieldCopier, oofE_Table, dbAbstractBrowseHelper, dbAbstractEditHelper, dbBrowseHelper, dbHierBrowseHelper, dbTableViewDisplay, OOF_recordCacheCopier, dbRelRefBase, and oofRepData.
