Detailed Description

Field gadget class.

Library: dbgadget

The IliDbToggle class defines toggle gadgets that can be connected to a data source. A IliDbToggle gadget inherits the following properties from the IliFieldItf class:

IliFieldItf.

Accessors

Accessors provide a scriptable and uniform way to inspect and modify an object by using its base class methods IlvValueInterface::queryValue(), IlvValueInterface::queryValues(), IlvValueInterface::changeValue(), IlvValueInterface::changeValues(). This class inherits the accessors of its superclasses IlvToggle and IliFieldItf, and adds the following ones:

Data accessors

Name Type Equivalent methods
is3StateMode Object is3StatesMode(), set3StatesMode()

By default, the gadget is assigned the integer 1 to its value when it is in the checked state and 0 when it is in the unchecked state.

A table, known as a foreign table, can be used to map the checked and unchecked states to values other than 0 and 1.

For example, if you want to use strings "True" and "False" instead of integers 1 and 0, you could :

Member Function Documentation

virtual IlBoolean IliDbToggle::f_complete ( )
virtual

Updates the internal value of the field, according to its current external representation and its foreign table, provided completion is enabled for the field.

For more information on completion, see the f_iscompletionEnabled() member function.

Returns
IlTrue if successful.

Reimplemented from IliFieldItf.

virtual IlBoolean IliDbToggle::f_externalToInternal ( )
virtual

Updates the internal value of a field according to its current external representation.

Returns
IlTrue if successful and IlFalse otherwise. Note that this may fail due to the fact that not all external representations can be converted to a value object. For example, this is especially true for text fields that are used to edit numeric or date values.

Reimplemented from IliFieldItf.

virtual const char* IliDbToggle::f_getLabel ( ) const
virtual

Returns the label displayed by the field gadget.

Returns
The label.

Reimplemented from IliFieldItf.

virtual const IliValue& IliDbToggle::f_getValue ( IlBoolean  internal = IlFalse) const
virtual

Returns the value of the field.

Parameters
internalIf IlTrue, the returned value does not necessarily reflect the state of the field as the user sees it.
Returns
The value.

Reimplemented from IliFieldItf.

virtual IlBoolean IliDbToggle::f_hasLabel ( ) const
virtual

Returns IlTrue if the field gadget can display a label.

Returns
IlTrue if the field gadget can display a label.

Reimplemented from IliFieldItf.

virtual IlBoolean IliDbToggle::f_isConsistent ( ) const
virtual

Returns IlTrue if the internal value of the field corresponds to its current external representation.

A return value of IlFalse means that the external representation of the field has been edited by the end-user since the last time one of the member functions, f_setValue(), f_externalToInternal(), f_internalToExternal() or f_complete() was successfully called.

Returns
IlTrue if the internal value of the field corresponds to its current external representation.

Reimplemented from IliFieldItf.

Reimplemented in IliSimpleToggle.

virtual IlBoolean IliDbToggle::f_isReadOnly ( ) const
virtual

Returns IlTrue if the field is read-only.

Returns
IlTrue if the field is read-only.

Reimplemented from IliFieldItf.

virtual void IliDbToggle::f_setForeignDisplayColumnName ( const char *  name)
virtual

Sets the name of the column of the foreign table that will serve as a result, when the table is used as a map to convert internal values into external representations.

Parameters
nameThe column name.

Reimplemented from IliFieldItf.

virtual void IliDbToggle::f_setForeignTable ( IliTable tbl,
IlBoolean  owner = IlFalse 
)
virtual

Sets the foreign table of the field.

Parameters
tblThe table.
ownerDetermines whether the field will own the table.

Reimplemented from IliFieldItf.

virtual void IliDbToggle::f_setForeignValueColumnName ( const char *  name)
virtual

Sets the name of the column of the foreign table that will serve as a key, when the table is used as a map to convert internal values into external representations.

Parameters
nameThe column name.

Reimplemented from IliFieldItf.

virtual void IliDbToggle::f_setLabel ( const char *  label)
virtual

Sets the label of the field gadget.

Parameters
labelThe label.

Reimplemented from IliFieldItf.

virtual void IliDbToggle::f_setReadOnly ( IlBoolean  flag)
virtual

Sets the read-only property for the field.

Parameters
flagThe read-only flag.

Reimplemented from IliFieldItf.

virtual IlBoolean IliDbToggle::f_setValue ( const IliValue val,
IlBoolean  internal = IlFalse 
)
virtual

Sets the value of the field.

Parameters
valThe value.
internalIf IlFalse, then the external representation and the display of the field are automatically updated.
Returns
IlTrue if successful, and IlFalse otherwise.

Reimplemented from IliFieldItf.

virtual IlBoolean IliDbToggle::is3StatesMode ( ) const
virtual

Returns IlTrue if the IliDbToggle handles the 0 value in addition to the two Boolean values.

Note that the 3-states mode is only effective when the marker of the IliDbToggle has a check-box look (see IlvToggle::setRadio()).

Returns
IlTrue if the IliDbToggle handles the 0 value in addition to the two Boolean values, 0 and 1. By default this property is IlTrue.
virtual void IliDbToggle::set3StatesMode ( IlBoolean  flag)
virtual

Enables/disables the handling of 0 values.

Parameters
flagIf IlTrue, enables the handling of 0 values.
