Member Function Documentation

virtual IlBoolean IliEntryField::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.

Reimplemented in IliTableComboBox.

virtual IlvAlignment IliEntryField::f_getAlignment ( ) const

virtual

Returns the text alignment of the field.

Returns

The alignment.

Reimplemented from IliFieldItf.

virtual const IliFormat& IliEntryField::f_getFormat ( ) const

virtual

Returns the format used to derive the external representation of the field from its internal value.

Returns

The format.

Reimplemented from IliFieldItf.

virtual const IliInputMask& IliEntryField::f_getMask ( ) const

virtual

Returns the input mask used to edit values in the field.

Currently, the classes that take into account the input mask are: IliEntryField and its subclasses.

Returns

The mask.

Reimplemented from IliFieldItf.

virtual IlShort IliEntryField::f_getMaxLength ( ) const

virtual

Returns the maximum length allowed for the external representation of the field.

Returns

The maximum.

Reimplemented from IliFieldItf.

virtual const IliValue& IliEntryField::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 IliEntryField::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 IliTableComboBox.

virtual IlBoolean IliEntryField::f_isReadOnly ( ) const

virtual

Returns IlTrue if the field is read-only.

Returns

IlTrue if the field is read-only.

Reimplemented from IliFieldItf.

Reimplemented in IliAbstractComboBox.

virtual void IliEntryField::f_setAlignment ( IlvAlignment  align )

virtual

Sets the text alignment of the field.

Parameters

align

The alignment.

Reimplemented from IliFieldItf.

virtual void IliEntryField::f_setFormat ( const IliFormat &  fmt )

virtual

Sets the format used to derive the external representation of the field from its internal value.

Parameters

fmt	The format.

Reimplemented from IliFieldItf.

virtual void IliEntryField::f_setInputModified ( IlBoolean  flag )

virtual

Sets the input-modified attribute of the field.

This member function is presented here for completeness. However, it should be used with care since it may cause the field, and other related components, to be in error with regard to the current state of the field.

Parameters

flag	The input-modified attribute.

Reimplemented from IliFieldItf.

virtual void IliEntryField::f_setMask ( const IliInputMask &  msk )

virtual

Sets the input mask.

Parameters

msk

The mask.

Reimplemented from IliFieldItf.

virtual void IliEntryField::f_setMaxLength ( IlShort  vmax )

virtual

Sets the maximum length allowed for the external representation of the field.

Parameters

vmax	The maximum length.

Reimplemented from IliFieldItf.

virtual void IliEntryField::f_setReadOnly ( IlBoolean  flag )

virtual

Sets the read-only property for the field.

Parameters

flag	The read-only flag.

Reimplemented from IliFieldItf.

Reimplemented in IliAbstractComboBox.

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

virtual

Sets the value of the field.

Parameters

val	The value.
internal	If IlFalse, then the external representation and the display of the field are automatically updated.

Returns

IlTrue if successful, and IlFalse otherwise.

Reimplemented from IliFieldItf.

Reimplemented in IliTableComboBox.

const char* IliEntryField::formatValue ( IliString &  dest, const IliValue &  val  )

protected

Returns a character string which contains the formatted value.

Parameters

dest	The string which contains the formatted value.
val	The value.

Returns

A character string which contains the formatted value.

void IliEntryField::setLabelSilently ( const char *  label )

protected

Sets a new label and launches the drawing of the new label.

Parameters

label

The label.

virtual void IliEntryField::valueToLabel ( const IliValue &  value )

protectedvirtual

Sets the value to the label of the entry field.

However if a format is defined the function formatValue is called to format the value. If there is no format but there is a mask, the value is formatted with the mask.

At the end the function setLabelSilently is called to set the value to the label and to launch the drawing of the label.

Parameters

value

The value.
