Member Function Documentation

dbGUIAdapter * dbFieldLink::adapter (   )  const [inline, inherited]

bool dbFieldLink::alwaysReadOnly (   )  const [inline, inherited]

void dbFieldLink::copyFieldToLink (   )  [virtual, inherited]

Reimplemented in dbFieldPickLink, and dbBoolLink.

void dbFieldLink::copyLinkToField (   )  [virtual, inherited]

Reimplemented in dbFieldPickLink, and dbBoolLink.

void OOF_PublicBase::describe (  std::ostream &  os  )  const [virtual, inherited]

Provide human-readable information about object. Overriden to provide much more detail particularly for dbTable::describe() which provides full schema. Reimplemented in dbTable, dbConnect, dbField, dbChar, dbFixedBinary, and dbRelRefBase.

dbField * dbFieldLink::field (   )  const [inline, inherited]

purposely non-virtual as subclasses return different types Used by dbGUIAdapters such as dbGUIAdaptEditPane::setFieldLink to get the field in order to query database characteristics. Returns: dbField* to the field we link. Reimplemented in dbUshortLink.

bool OOF_PublicBase::hidden (   )  const [inline, inherited]

void OOF_PublicBase::hide (  bool  hideIt = true  )  [inline, inherited]

void dbFieldLink::highlightLink (   )  [virtual, inherited]

Visually highlight a link, usually becoming edit focus. dbAbstractEditHelper::ValidateLinks calls us to highlight the first invalid link it finds.

bool dbFieldLink::isDirty (   )  const [inline, inherited]

bool dbFieldLink::isReadOnly (   )  const [inline, inherited]

bool dbFieldLink::leaveLink (   )  [virtual, inherited]

Reimplemented in dbFieldPickLink, and oofRepEditLink.

bool dbFieldLink::linkEqualsField (   )  const [virtual, inherited]

Reimplemented in dbFieldPickLink, and dbBoolLink.

bool dbFieldLink::linkIsEmpty (   )  const [inherited]

void dbFieldLink::markClean (   )  [inline, inherited]

void dbFieldLink::maybeChangeTargetLink (   )  [inline, inherited]

void dbFieldLink::maybeDirty (   )  [inline, inherited]

oofString OOF_PublicBase::name (   )  const [virtual, inherited]

Reimplemented in dbTable, dbConnect, dbField, and OOF_adornerHolder.

void dbFieldLink::owner (  dbHelper *   )  [inline, inherited]

not ctor param as can create without helper

dbHelper * dbFieldLink::owner (   )  const [inline, inherited]

void dbFieldLink::readOnly (  bool  becomeReadOnly = true  )  [virtual, inherited]

Change readonly state of link to accept or deny data entry. Won't allow enabling editing if can't edit record due to locking.

void dbFieldLink::setField (  dbField *  inField  )  [inline, inherited]

void dbFieldLink::tellGUIcareAboutLocking (   )  const [virtual, inherited]

Reimplemented in oofRepEditLink.

void dbNumericFieldLink::updateDerivedFieldDisplay (  bool  isNew  )  [virtual]

Reimplemented from dbFieldLink. Reimplemented in dbDateLink2Editor, and dbDateTimeLink2Editor.

bool dbFieldLink::validToLeaveForm (   )  [virtual, inherited]

Validate unique fields to ensure can accept this record without error from database. Warning: you probably still want to call this method if you override. Reimplemented in dbFieldPickLink.

bool dbFieldLink::validToLeaveLink (   )  [virtual, inherited]

Validate field contents, overridden if can check just contents. Lightweight check that allows tabbing between fields in open record. See also: validToLeaveForm for heavier check. dbDateLink2Editor::validToLeaveLink Reimplemented in dbDateLink2Editor, and dbDateTimeLink2Editor.
