Member Function Documentation

QString KexiDBDateTimeEdit::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 47 of file kexidbdatetimeedit.h.

QCString KexiDBDateTimeEdit::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 48 of file kexidbdatetimeedit.h.

QVariant KexiDBDateTimeEdit::value (  )  [virtual]

Returns:
value currently represented by this item.

Implements KexiDataItemInterface.

Definition at line 113 of file kexidbdatetimeedit.cpp.

void KexiDBDateTimeEdit::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.

Parameters:
displayText 
Todo:
paint this text: text

Implements KexiFormDataItemInterface.

Definition at line 87 of file kexidbdatetimeedit.cpp.

bool KexiDBDateTimeEdit::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 118 of file kexidbdatetimeedit.cpp.

bool KexiDBDateTimeEdit::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 124 of file kexidbdatetimeedit.cpp.

bool KexiDBDateTimeEdit::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 129 of file kexidbdatetimeedit.cpp.

QWidget * KexiDBDateTimeEdit::widget (  )  [virtual]

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

Reimplemented from KexiFormDataItemInterface.

Definition at line 142 of file kexidbdatetimeedit.cpp.

bool KexiDBDateTimeEdit::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 147 of file kexidbdatetimeedit.cpp.

bool KexiDBDateTimeEdit::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 156 of file kexidbdatetimeedit.cpp.

void KexiDBDateTimeEdit::clear (  )  [virtual]

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

Implements KexiDataItemInterface.

Definition at line 166 of file kexidbdatetimeedit.cpp.

void KexiDBDateTimeEdit::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 81 of file kexidbdatetimeedit.h.

void KexiDBDateTimeEdit::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 82 of file kexidbdatetimeedit.h.

void KexiDBDateTimeEdit::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 136 of file kexidbdatetimeedit.cpp.

void KexiDBDateTimeEdit::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.
