Detailed Description

Field gadget class.

Library: dbgadget

The IliToggleSelector class defines a gadget that contains a set of toggle gadgets. Each toggle gadget corresponds to a row of the foreign table. A maximum of one toggle can be checked. The value of the toggle selector is closely related to which toggle is checked. A IliToggleSelector gadget inherits the following properties from the IliFieldItf class:

a value (which may be connected to a data source),
a foreign table,
a column of the foreign table known as the value column,
a column of the foreign table known as the display column,
a label (see IliFieldItf::f_getLabel() and IliFieldItf::f_setLabel()).

When a toggle selector receives a new value, it checks the foreign table to find a row that contains this value in its value column. If such a row is found, the toggle selector checks the toggle that has the value of the display column of this row, as a label. Any other previously checked toggle is unchecked. Therefore, a toggle selector does not display its actual value. Instead, it displays another value that is derived from the original value, through the foreign table. The foreign table serves as a value converter. In addition, if the user edits the value displayed by the toggle selector, the edited value is converted back in a reversal of the procedure described above. A row that contains this value in its display column is searched for in the foreign table. If such a row is found, the value of the combo box changes to the value contained in the value column of the row. As an alternative to using a foreign table, it is possible to alter the toggles and their labels directly, using one of the member functions, setLabels(), setLabel(), insertLabel(), appendLabel(), or removeLabel(). Note that these member functions may not be used in conjunction with a foreign table. When the toggle selector has no foreign table, its value is an integer ranging from 0 to one less than the number of toggles.

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 IliGadgetSet and IliFieldItf, and adds the following ones:

label The label. It is copied.

Returns: IlTrue if successful.

virtual IlBoolean IliToggleSelector::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* IliToggleSelector::f_getLabel ( ) const

virtual

Returns the label displayed by the field gadget.

Returns: The label.

Reimplemented from IliFieldItf.

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

virtual

Returns the value of the field.

Parameters

internal If 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 IliToggleSelector::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 IliToggleSelector::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.

virtual

Returns IlTrue if the field is read-only.

Returns: IlTrue if the field is read-only.

Reimplemented from IliFieldItf.

Reimplemented from IliFieldItf.

const char* IliToggleSelector::getLabel ( IlInt index ) const

Returns a label.

Parameters

index The label position.
