Constructor & Destructor Documentation

◆ KexiDBDoubleSpinBox()

KexiDBDoubleSpinBox::KexiDBDoubleSpinBox ( TQWidget * parent,
const char * name = 0 )

Member Function Documentation

◆ clear()

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.

◆ cursorAtEnd()

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.
Todo
?

Implements KexiDataItemInterface.

Definition at line 103 of file kexidbdoublespinbox.cpp.

◆ cursorAtStart()

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.

◆ dataSource()

TQString KexiDBDoubleSpinBox::dataSource ( ) const
inline

Definition at line 41 of file kexidbdoublespinbox.h.

◆ dataSourceMimeType()

TQCString KexiDBDoubleSpinBox::dataSourceMimeType ( ) const
inline

Definition at line 42 of file kexidbdoublespinbox.h.

◆ isReadOnly()

bool KexiDBDoubleSpinBox::isReadOnly ( ) const
virtual
Returns
'readOnly' flag for this widget.

Reimplemented from KexiDataItemInterface.

◆ setDataSource

void KexiDBDoubleSpinBox::setDataSource ( const TQString & ds)

◆ setDataSourceMimeType

void KexiDBDoubleSpinBox::setDataSourceMimeType ( const TQCString & ds)
inlineslot

◆ setEnabled

void KexiDBDoubleSpinBox::setEnabled ( bool enabled)
virtualslot

Definition at line 48 of file kexidbdoublespinbox.cpp.

◆ setInvalidState()

void KexiDBDoubleSpinBox::setInvalidState ( const TQString & 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.

Todo
move this to KexiDataItemInterface::setInvalidStateInternal() ?

Implements KexiFormDataItemInterface.

Definition at line 35 of file kexidbdoublespinbox.cpp.

◆ setReadOnly

void KexiDBDoubleSpinBox::setReadOnly ( bool set)
virtualslot

Definition at line 87 of file kexidbdoublespinbox.cpp.

◆ setValueInternal()

void KexiDBDoubleSpinBox::setValueInternal ( const TQVariant & add,
bool removeOld )
protectedvirtual

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.

◆ slotValueChanged

void KexiDBDoubleSpinBox::slotValueChanged ( )
slot

Definition at line 67 of file kexidbdoublespinbox.cpp.

◆ value()

TQVariant KexiDBDoubleSpinBox::value ( )
virtual
Returns
value currently represented by this item.

Implements KexiDataItemInterface.

Definition at line 62 of file kexidbdoublespinbox.cpp.

◆ valueIsEmpty()

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.

◆ valueIsNull()

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.

◆ widget()

TQWidget * KexiDBDoubleSpinBox::widget ( )
virtual
Returns
the view widget of this item, e.g. line edit widget.

Reimplemented from KexiFormDataItemInterface.
