Detailed Description

Input mask class.

Library: dataccess

This class defines the mask that is used to enter data into an IliEntryField. The mask is defined by a character string (see specifications syntax). The mask has two modes:

• Display mode-If a format is not defined, the mask is used to format the data before it is displayed. This is true when the IliEntryField does not have the keyboard focus.
• Edit mode-In this mode, all missing characters are replaced by the placeholder character (by default, the character is underlined). There are some predefined masks for the date and time. However, you can define your own predefined masks in the Masks section of the Application Properties panel in Rogue Wave Views Studio.

Member Function Documentation

static void IliInputMask::AddAlias ( const char *  aliasName, const char *  definition  )

static

Defines a new alias.

Parameters

aliasName	The alias name.
definition	The alias definition.

IlBoolean IliInputMask::format	(	IliString &	dest,
		const IliValue &	src,
		IlBoolean	forEdit
	)		const

Formats a value.

Parameters

dest	The formatted string.
src	The value.
forEdit	If IlTrue, the missing characters are replaced by the character returned by the function GetPlaceHolderChar.

Returns

IlTrue if it is successful.

void IliInputMask::formatForClipboard	(	IliString &	dest,

static const char* IliInputMask::GetAliasDefinition ( const char *  aliasName )

static

Returns the alias definition.

Parameters

aliasName

The alias name.

Returns

The definition of the alias given by the aliasName parameter. Returns -1 if no such alias is found.

static

Returns the count of the mask aliases.

Returns

The count.

static IlInt IliInputMask::GetAliasIndex ( const char *  aliasName )

static

Returns the alias index.

Parameters

aliasName

The alias name.

Returns

The position of the alias given by the aliasName parameter. Returns -1 if no such alias is found.

static const char* IliInputMask::GetAliasName ( IlInt  aliasIndex )

static

Returns the name of one alias.

Parameters

aliasIndex

The alias index.

Returns

The name.

static IliInputMask& IliInputMask::GetDefaultMask ( )

static

Returns a constant reference to the default mask.

Returns

The default mask.

const char* IliInputMask::getDefinition

(

)

const

Returns the mask definition.

Returns

The definition.

static wchar_t IliInputMask::GetPlaceHolderChar ( )

static

Returns the character used to represent the missing character during the edit mode.

Returns

The character.

IlBoolean IliInputMask::isNull

(

)

const

Returns IlTrue if the mask definition is null.

Returns

IlTrue if the mask definition is null.

IliInputMask& IliInputMask::operator=

(

const IliInputMask &

msk

)

Copies a mask.

Parameters

msk	The mask which is copied.

int IliInputMask::operator==

(

const IliInputMask &

)

const

Compares two masks.

Returns

1 if the masks are equal.

void IliInputMask::read

(

IL_STDPREF istream &

input

)

Reads the mask from an input stream.

Parameters

input

The input stream.

static void IliInputMask::RemoveAlias ( IlInt  aliasIndex )

static

Removes an alias.

Parameters

aliasIndex

The alias index.

static void IliInputMask::SetAliasDefinition ( IlInt  aliasIndex, const char *  definition  )

static

Sets alias definition.

Parameters

aliasIndex	The alias index.
definition	The alias definition.

static void IliInputMask::SetAliasName ( IlInt  aliasIndex, const char *  name  )

static

Sets alias name.

Parameters

aliasIndex	The alias index.
name	The alias name.

void IliInputMask::setDefinition

(

const char *

definition

)

Sets the mask definition.

Parameters

definition

The definition.

static void IliInputMask::SetPlaceHolderValue ( IliPlaceHolderName  name, wchar_t  value  )

static

Changes a place holder which is used to define a mask.

You can use this function to change the value of the placeholders. For example, you decide that the colon is the date separator for the mask definition. But, in this case, you must change the placeholder for time separator because two placeholders can not have the same value, Except, for the placeholders about set of characters. Note: If you change the value for a placeholder, the correct working of the default mask is not guaranteed.

Parameters

name	The placeholder name.
value	The new value.

IlBoolean IliInputMask::unFormat	(	IliString &	dest,
		const char *	src
	)		const

Unformats a character string.

Parameters

dest	The unformatted string.
src	The string.

Returns

IlTrue if it is successful.

void IliInputMask::write

(

IL_STDPREF ostream &

output

)

const

Writes the mask definition to an output stream in such a way that it may be read back by the read member function.

Parameters

output

The output stream.
