Member Enumeration Documentation

◆ Tristate

enum KexiDBCheckBox::Tristate

Definition at line 68 of file kexidbcheckbox.h.

Constructor & Destructor Documentation

◆ KexiDBCheckBox()

KexiDBCheckBox::KexiDBCheckBox ( const TQString &  text,
TQWidget *  parent,
const char *  name = 0 
)

◆ ~KexiDBCheckBox()

KexiDBCheckBox::~KexiDBCheckBox ( )
virtual

Definition at line 37 of file kexidbcheckbox.cpp.

Member Function Documentation

◆ clear()

void KexiDBCheckBox::clear ( )
virtual

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

Implements KexiDataItemInterface.

Definition at line 120 of file kexidbcheckbox.cpp.

◆ cursorAtEnd()

bool KexiDBCheckBox::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 115 of file kexidbcheckbox.cpp.

◆ cursorAtStart()

bool KexiDBCheckBox::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.
Todo:
?

Implements KexiDataItemInterface.

Definition at line 110 of file kexidbcheckbox.cpp.

◆ dataSource()

TQString KexiDBCheckBox::dataSource ( ) const
inline

Definition at line 41 of file kexidbcheckbox.h.

◆ dataSourceMimeType()

TQCString KexiDBCheckBox::dataSourceMimeType ( ) const
inline

Definition at line 42 of file kexidbcheckbox.h.

◆ isReadOnly()

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

Reimplemented from KexiDataItemInterface.

Definition at line 99 of file kexidbcheckbox.cpp.

◆ isTristate()

KexiDBCheckBox::Tristate KexiDBCheckBox::isTristate ( ) const

Definition at line 132 of file kexidbcheckbox.cpp.

◆ isTristateInternal()

bool KexiDBCheckBox::isTristateInternal ( ) const
protected
Returns
true in isTristate() == TristateDefault and the widget has bound data source or if isTristate() == TristateOn, else false is returned.

Definition at line 137 of file kexidbcheckbox.cpp.

◆ setDataSource

void KexiDBCheckBox::setDataSource ( const TQString &  ds)
slot

Definition at line 156 of file kexidbcheckbox.cpp.

◆ setDataSourceMimeType

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

Definition at line 78 of file kexidbcheckbox.h.

◆ setDisplayDefaultValue()

void KexiDBCheckBox::setDisplayDefaultValue ( TQWidget *  widget,
bool  displayDefaultValue 
)
virtual

Reimplemented after KexiFormDataItemInterface.

Reimplemented from KexiFormDataItemInterface.

Definition at line 162 of file kexidbcheckbox.cpp.

◆ setEnabled()

void KexiDBCheckBox::setEnabled ( bool  enabled)
virtual

Definition at line 53 of file kexidbcheckbox.cpp.

◆ setInvalidState()

void KexiDBCheckBox::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 41 of file kexidbcheckbox.cpp.

◆ setReadOnly

void KexiDBCheckBox::setReadOnly ( bool  readOnly)
virtualslot

This implementation just disables read only widget.

Definition at line 61 of file kexidbcheckbox.cpp.

◆ setTristate()

void KexiDBCheckBox::setTristate ( KexiDBCheckBox::Tristate  tristate)

Definition at line 125 of file kexidbcheckbox.cpp.

◆ setValueInternal()

void KexiDBCheckBox::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 66 of file kexidbcheckbox.cpp.

◆ slotStateChanged

void KexiDBCheckBox::slotStateChanged ( int  state)
slot

Definition at line 84 of file kexidbcheckbox.cpp.

◆ updateTristate()

void KexiDBCheckBox::updateTristate ( )
protected

Updates tristate in TQCheckBox itself according to m_tristate.

Todo:
the data source may be defined as NOT NULL... thus disallowing NULL state

Definition at line 145 of file kexidbcheckbox.cpp.

◆ value()

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

Implements KexiDataItemInterface.

Definition at line 77 of file kexidbcheckbox.cpp.

◆ valueIsEmpty()

bool KexiDBCheckBox::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 94 of file kexidbcheckbox.cpp.

◆ valueIsNull()

bool KexiDBCheckBox::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 89 of file kexidbcheckbox.cpp.

◆ widget()

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

Reimplemented from KexiFormDataItemInterface.

Definition at line 105 of file kexidbcheckbox.cpp.
