Member Function Documentation

QString KexiDBDateEdit::dataSource (  )  const [inline]

Returns:
the name of the data source for this widget.

Data source usually means here a table or query, a field name or an expression.

Reimplemented from KexiFormDataItemInterface.

Definition at line 52 of file kexidbdateedit.h.

QCString KexiDBDateEdit::dataSourceMimeType (  )  const [inline]

Returns:
the mime type of the data source for this widget. Data source mime type means here types like "kexi/table" or "kexi/query" in.the data source is set to object (as within form or subform) or is empty if the data source is set to table field or query column.

Reimplemented from KexiFormDataItemInterface.

Definition at line 53 of file kexidbdateedit.h.

QVariant KexiDBDateEdit::value (  )  [virtual]

Returns:
value currently represented by this item.

Implements KexiDataItemInterface.

Definition at line 115 of file kexidbdateedit.cpp.

void KexiDBDateEdit::setInvalidState ( const QString &  displayText  )  [virtual]

Sets 'invalid' state, e.g. a text editor widget should display text displayText and become read only to prevent entering data, because updating at the database backend is not available. displayText is usually set to something i18n'd like "#NAME?". Note: that even widgets that usualy do not display texts (e.g. pixmaps) should display displayText too.

Implements KexiFormDataItemInterface.

Definition at line 78 of file kexidbdateedit.cpp.

bool KexiDBDateEdit::valueIsNull (  )  [virtual]

Returns:
true if editor's value is null (not empty) Used for checking if a given constraint within table of form is met.

Implements KexiDataItemInterface.

Definition at line 120 of file kexidbdateedit.cpp.

bool KexiDBDateEdit::valueIsEmpty (  )  [virtual]

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

Only few data types can accept "EMPTY" property (use KexiDB::Field::hasEmptyProperty() to check this). Used for checking if a given constraint within table or form is met.

Implements KexiDataItemInterface.

Definition at line 125 of file kexidbdateedit.cpp.

bool KexiDBDateEdit::isReadOnly (  )  const [virtual]

Returns:
'readOnly' flag for this widget.

Todo:
: data/time edit API has no readonly flag, so use event filter to avoid changes made by keyboard or mouse when m_readOnly==true

isEnabled();

Reimplemented from KexiDataItemInterface.

Definition at line 130 of file kexidbdateedit.cpp.

QWidget * KexiDBDateEdit::widget (  )  [virtual]

Returns:
the view widget of this item, e.g. line edit widget.

Reimplemented from KexiFormDataItemInterface.

Definition at line 143 of file kexidbdateedit.cpp.

bool KexiDBDateEdit::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 148 of file kexidbdateedit.cpp.

bool KexiDBDateEdit::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 157 of file kexidbdateedit.cpp.

void KexiDBDateEdit::clear (  )  [virtual]

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

Implements KexiDataItemInterface.

Definition at line 167 of file kexidbdateedit.cpp.

void KexiDBDateEdit::setDataSource ( const QString &  ds  )  [inline, slot]

Sets the name of the data source for this widget.

Data source usually means here a table or query or field name name.

Reimplemented from KexiFormDataItemInterface.

Definition at line 94 of file kexidbdateedit.h.

void KexiDBDateEdit::setDataSourceMimeType ( const QCString &  ds  )  [inline, slot]

Sets the mime type of the data source for this widget. Data source usually means here a "kexi/table" or "kexi/query".

See also:
dataSourceMimeType()

Reimplemented from KexiFormDataItemInterface.

Definition at line 95 of file kexidbdateedit.h.

void KexiDBDateEdit::setReadOnly ( bool  set  )  [virtual, slot]

Changes 'read only' flag, for this widget. Typically this flag can be passed to a widget itself, e.g. KLineEdit::setReadOnly(bool).

Implements KexiFormDataItemInterface.

Definition at line 137 of file kexidbdateedit.cpp.

void KexiDBDateEdit::setValueInternal ( const QVariant &  add,
bool  removeOld 
) [protected, virtual]

Initializes this editor with add value, which should be somewhat added to the current value (already storted in m_origValue). If removeOld is true, a value should be set to add, otherwise -it should be set to current m_origValue + add, if possible. Implement this.

Implements KexiDataItemInterface.
