Member Function Documentation
void KexiDBDoubleSpinBox::clear | ( | ) | [virtual] |
clears item's data, so the data will contain NULL data
Implements KexiDataItemInterface.
Definition at line 108 of file kexidbdoublespinbox.cpp.
bool KexiDBDoubleSpinBox::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 103 of file kexidbdoublespinbox.cpp.
bool KexiDBDoubleSpinBox::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 98 of file kexidbdoublespinbox.cpp.
QString KexiDBDoubleSpinBox::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 kexidbdoublespinbox.h.
QCString KexiDBDoubleSpinBox::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 kexidbdoublespinbox.h.
bool KexiDBDoubleSpinBox::isReadOnly | ( | ) | const [virtual] |
- Returns:
- 'readOnly' flag for this widget.
Reimplemented from KexiDataItemInterface.
Definition at line 82 of file kexidbdoublespinbox.cpp.
void KexiDBDoubleSpinBox::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 67 of file kexidbdoublespinbox.h.
void KexiDBDoubleSpinBox::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 68 of file kexidbdoublespinbox.h.
void KexiDBDoubleSpinBox::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 35 of file kexidbdoublespinbox.cpp.
void KexiDBDoubleSpinBox::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 56 of file kexidbdoublespinbox.cpp.
QVariant KexiDBDoubleSpinBox::value | ( | ) | [virtual] |
- Returns:
- value currently represented by this item.
Implements KexiDataItemInterface.
Definition at line 62 of file kexidbdoublespinbox.cpp.
bool KexiDBDoubleSpinBox::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 77 of file kexidbdoublespinbox.cpp.
bool KexiDBDoubleSpinBox::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 72 of file kexidbdoublespinbox.cpp.
QWidget * KexiDBDoubleSpinBox::widget | ( | ) | [virtual] |
- Returns:
- the view widget of this item, e.g. line edit widget.
Reimplemented from KexiFormDataItemInterface.
