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
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 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
alignThe 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
fmtThe 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
flagThe input-modified attribute.

Reimplemented from IliFieldItf.

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

Sets the input mask.

Parameters
mskThe 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
vmaxThe maximum length.

Reimplemented from IliFieldItf.

virtual void IliEntryField::f_setReadOnly ( IlBoolean  flag)
virtual

Sets the read-only property for the field.

Parameters
flagThe 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
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.

Reimplemented in IliTableComboBox.

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

Returns a character string which contains the formatted value.

Parameters
destThe string which contains the formatted value.
valThe 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
labelThe 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
valueThe value.

Reimplemented in IliTableComboBox.
