void KexiBlobTableEdit::clear ( ) [protected, virtual, slot]

clears item's data, so the data will contain NULL data

Implements KexiDataItemInterface.

bool KexiBlobTableEdit::cursorAtEnd ( ) [virtual]

Returns:
true if the item widget's cursor (whatever that means, eg. line edit cursor) is at the end of editor's contents. This can inform table/form view that after pressing "right arrow" key should stop editing and move to a field on the right hand.

Implements KexiDataItemInterface.
Definition at line 404 of file kexiblobtableedit.cpp.

bool KexiBlobTableEdit::cursorAtStart ( ) [virtual]

Returns:
true if the item widget's cursor (whatever that means, eg. line edit cursor) is at the beginning of editor's contents. This can inform table/form view that after pressing "left arrow" key should stop editing and move to a field on the left hand.
