Member Function Documentation

QString KexiDBIntSpinBox::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 40 of file kexidbintspinbox.h.

QCString KexiDBIntSpinBox::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 41 of file kexidbintspinbox.h.

QVariant KexiDBIntSpinBox::value (  )  [virtual]

Returns:
value currently represented by this item.

Implements KexiDataItemInterface.

Definition at line 63 of file kexidbintspinbox.cpp.

void KexiDBIntSpinBox::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 36 of file kexidbintspinbox.cpp.

bool KexiDBIntSpinBox::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 73 of file kexidbintspinbox.cpp.

bool KexiDBIntSpinBox::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 78 of file kexidbintspinbox.cpp.

bool KexiDBIntSpinBox::isReadOnly (  )  const [virtual]

Returns:
'readOnly' flag for this widget.

Reimplemented from KexiDataItemInterface.

Definition at line 83 of file kexidbintspinbox.cpp.

QWidget * KexiDBIntSpinBox::widget (  )  [virtual]

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

Reimplemented from KexiFormDataItemInterface.

Definition at line 94 of file kexidbintspinbox.cpp.

bool KexiDBIntSpinBox::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 99 of file kexidbintspinbox.cpp.

bool KexiDBIntSpinBox::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 104 of file kexidbintspinbox.cpp.

void KexiDBIntSpinBox::clear (  )  [virtual]

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

Implements KexiDataItemInterface.

Definition at line 109 of file kexidbintspinbox.cpp.

void KexiDBIntSpinBox::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 68 of file kexidbintspinbox.h.

void KexiDBIntSpinBox::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 69 of file kexidbintspinbox.h.

void KexiDBIntSpinBox::setReadOnly ( bool  readOnly  )  [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 88 of file kexidbintspinbox.cpp.

void KexiDBIntSpinBox::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.
