Member Function Documentation

void KexiBoolTableEdit::clear ( ) [virtual]

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

Implements KexiDataItemInterface.
Definition at line 71 of file kexibooltableedit.cpp.
References KexiTableEdit::field(), and m_currentValue.

void KexiBoolTableEdit::clickedOnContents ( ) [virtual]

Allows to define reaction for clicking on cell's contents. Currently it's used for editor of type boolean, where we want to toggle true/false on single mouse click.
See also:
hasFocusableWidget(), KexiBoolTableEdit. Default implementation does nothing.

Reimplemented from KexiDataItemInterface.
Definition at line 120 of file kexibooltableedit.cpp.
References KexiTableEdit::field(), and m_currentValue.

bool KexiBoolTableEdit::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 84 of file kexibooltableedit.cpp.

bool KexiBoolTableEdit::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.

Implements KexiDataItemInterface.
Definition at line 79 of file kexibooltableedit.cpp.

void KexiBoolTableEdit::handleAction ( const QString & actionName ) [virtual]

Handles action having standard name actionName. Action could be: "edit_cut", "edit_paste", etc.
Reimplemented from KexiDataItemInterface.
Definition at line 133 of file kexibooltableedit.cpp.
References KexiCSVExport::Clipboard, KexiTableEdit::editRequested(), KexiTableEdit::field(), handleCopyAction(), m_currentValue, KexiDataItemInterface::m_origValue, KexiTableEdit::repaintRelatedCell(), and value().

void KexiBoolTableEdit::handleCopyAction ( const QVariant & value,

const QVariant & visibleValue

) [virtual]

Handles copy action for value. Copies empty string for null, "1" for true, "0" for false. visibleValue is unused here. Reimplemented after KexiTableEdit.
Implements KexiTableEdit.

void KexiBoolTableEdit::hintClicked ( ) [signal]

void KexiBoolTableEdit::setupContents ( QPainter * p,

bool focused,

const QVariant & val,

QString & txt,

int & align,

int & x,

int & y_offset,

int & w,

int & h

) [virtual]

For reimplementation. Sets up and paints cell's contents using context of val value. focused is true if the cell is focused. align is set using Qt::AlignmentFlags. Some additional things may be painted using p, but it is not needed to paint the text (this is done automatically outside of this method).
Before calling, x, y_offset, w, h parameters are initialized, but you can tune these values depending on the context. You should set txt to a text representation of val, otherwise no text will be painted.
p can be 0 - in this case no painting should be performed, becasue caller only expects that x, y_offset, w, h, txt parameters are tuned, if needed. p painter's pen is set to foreground color (usually black) that should be used to paint foreground information, if needed. For example boolean editor widget paints a rectangle using this color.

void KexiBoolTableEdit::setValueInternal ( const QVariant & add,

bool removeOld

) [protected, virtual]

initializes this editor with add value

Implements KexiDataItemInterface.

References m_currentValue, and KexiDataItemInterface::m_origValue.

void KexiBoolTableEdit::showHintButton ( ) [protected]

QVariant KexiBoolTableEdit::value ( ) [virtual]

Returns:
value currently represented by this item.

Implements KexiDataItemInterface.

bool KexiBoolTableEdit::valueIsEmpty ( ) [virtual]

Returns:
true if editor's value is empty (not null). Only few field types can accept "EMPTY" property (check this with KexiDB::Field::hasEmptyProperty()),

Implements KexiDataItemInterface.
Definition at line 60 of file kexibooltableedit.cpp.
References m_currentValue.

bool KexiBoolTableEdit::valueIsNull ( ) [virtual]

Returns:
true if editor's value is null (not empty)

Implements KexiDataItemInterface.
Definition at line 55 of file kexibooltableedit.cpp.
References m_currentValue.

int KexiBoolTableEdit::widthForValue ( QVariant & val,

const QFontMetrics & fm

) [virtual]

Returns:
width of value. Reimplemented after KexiTableEdit.

Reimplemented from KexiTableEdit.
