Detailed Description

The CodePage class.

This class is used to convert from EBCDIC to a Unicode character, or from an entered keyboard character to EBCDIC.

It's probably not the best way to do it, but it works.

Constructor & Destructor Documentation

CodePage()

CodePage::CodePage

(

)

CodePage::CodePage - Code page representation.

CodePage contains the various codepages used by 3270 displays. Built in code pages are currently 037 (US), 285 (UK) and 310 (Graphics).

Each code page is represented by 256 Unicode characters which represent the EBCDIC code points from 0x00 to 0xFF in Unicode form, and a corresponding 256 bytes held as EBCDIC characters, representing the ASCII (Latin 1) characters for those positions in EBCDIC.

The default code page at 'power on' is 037.

Member Function Documentation

getCodePageList()

const QStringList CodePage::getCodePageList

(

)

const

CodePage::getCodePageList - return a QStringList of the available codepages.

Returns

A list of the available code pages

getCodePageList is used in the Preferences dialog to provide a drop-down list of codepages that the user can choose from.

Codepages can be hidden from the user's view by setting the 'selectable' flag in the structure to false.

getEBCDIC()

uchar CodePage::getEBCDIC

(

uchar

ascii

)

const

CodePage::getEBCDIC.

Parameters

ascii

- the ASCII character for which the EBCDIC equivalent is to be returned

Returns

The EBCDIC character for the passed ASCII equivalent

Return the EBCDIC character for the ASCII one passed.

getUnicodeChar()

QString CodePage::getUnicodeChar

(

uchar

ebcdic

)

const

CodePage::getUnicodeChar - return the Unicode character from the EBCDIC character.

Parameters

ebcdic

- the character in EBCDIC

Returns

The Unicode equivalent of the EBCDIC character

getUnicodeChar returns the Unicode equivalent of the EBCDIC character passed.

getUnicodeGraphicChar()

QString CodePage::getUnicodeGraphicChar

(

uchar

ebcdic

)

const

CodePage::getUnicodeGraphicChar - return the Unicode equivalent of the EBCIDC character.

Parameters

ebcdic

- the Graphic Escape EBCDIC character

Returns

The Unicode equivalent of the EBCDIC character

getUnicodeGraphicChar returns the Unicode character for the EBCIDC "Graphic Escape" character passed. This is simply the standard EBCDIC character, but from the 310 codepage.

setCodePage()

void CodePage::setCodePage

(

QString

codepage

)

CodePage::setCodePage - set the current codepage.

Parameters

codepage

- the codepage by name to be set.

setCodePage is used when the user chooses a different code page, either when loading a new session setting or manually changing it in the Preferences dialog.
