Member Function Documentation

void KexiDBLineEdit::clear (  )  [virtual]

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

Implements KexiDataItemInterface.

Definition at line 162 of file kexidblineedit.cpp.

bool KexiDBLineEdit::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 kexidblineedit.cpp.

bool KexiDBLineEdit::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 152 of file kexidblineedit.cpp.

QString KexiDBLineEdit::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 42 of file kexidblineedit.h.

QCString KexiDBLineEdit::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 43 of file kexidblineedit.h.

bool KexiDBLineEdit::isReadOnly (  )  const [virtual]

Returns:
'readOnly' flag for this widget.

Reimplemented from KexiDataItemInterface.

Definition at line 142 of file kexidblineedit.cpp.

void KexiDBLineEdit::setColumnInfo ( KexiDB::QueryColumnInfo cinfo  )  [virtual]

Used internally to set database column information. Reimplement if you need to do additional actions, e.g. set data validator based on field type. Don't forget about calling superclass implementation.

Reimplemented from KexiFormDataItemInterface.

Definition at line 167 of file kexidblineedit.cpp.

void KexiDBLineEdit::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 70 of file kexidblineedit.h.

void KexiDBLineEdit::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 71 of file kexidblineedit.h.

void KexiDBLineEdit::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 44 of file kexidblineedit.cpp.

void KexiDBLineEdit::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.

Definition at line 53 of file kexidblineedit.cpp.

QVariant KexiDBLineEdit::value (  )  [virtual]

Returns:
value currently represented by this item.

Implements KexiDataItemInterface.

Definition at line 88 of file kexidblineedit.cpp.

bool KexiDBLineEdit::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 134 of file kexidblineedit.cpp.

bool KexiDBLineEdit::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 129 of file kexidblineedit.cpp.

QWidget * KexiDBLineEdit::widget (  )  [virtual]

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

Reimplemented from KexiFormDataItemInterface.

Definition at line 147 of file kexidblineedit.cpp.
