## Detailed Description

Widget size can be constrained with the number of visible lines. A single line constraint will emulate QLineEdit. See setLinesVisible() for details. The maximum number of characters can be limited with setMaxLenght(). The characters can be limited in editor by setIgnoredCharacters() and setAcceptedCharacters(). Implementation: dplaintextedit.cpp

## Constructor & Destructor Documentation

## ◆ DPlainTextEdit()

Digikam::DPlainTextEdit::DPlainTextEdit | ( | unsigned int | lines,
|  | QWidget *const | parent = `nullptr`
| ) |  |
| explicit

Zero lines do not apply a size constraint.

## Member Function Documentation

## ◆ acceptedCharacters()

QString Digikam::DPlainTextEdit::acceptedCharacters | ( |  | ) | const

The mask of characters is passed as string (ex: "abcABC"). By default the mask is empty.

## ◆ ignoredCharacters()

QString Digikam::DPlainTextEdit::ignoredCharacters | ( |  | ) | const

The mask of characters is passed as string (ex: "+/!()"). By default the mask is empty.

## ◆ isClearButtonEnabled()

bool Digikam::DPlainTextEdit::isClearButtonEnabled | ( |  | ) | const

If enabled, the edit widget displays a trailing clear button when it contains some text, otherwise the edit widget does not show a clear button. This option only take effect in QLineEdit emulation mode when lines visible is set to 1. See setLinesVisible() for details.

## ◆ returnPressed

void Digikam::DPlainTextEdit::returnPressed | ( |  | ) |
| signal

See setLinesVisible() for details.

## ◆ setCurrentLanguage()

void Digikam::DPlainTextEdit::setCurrentLanguage | ( | const QString & | lang | ) |

If this property is not set, spell-checker will try to auto-detect language by parsing the text. To reset this setting, pass a empty string as language. If Sonnet dependencies is not resolved, this method does nothing.

## ◆ setLinesVisible()

void Digikam::DPlainTextEdit::setLinesVisible | ( | unsigned int | lines | ) |

Lines must be superior or equal to 1 to apply a size constraint. Notes: if a single visible line is used, the widget emulate QLineEdit. a null value do not apply a size constraint.

## ◆ setMaxLength()

void Digikam::DPlainTextEdit::setMaxLength | ( | int | length | ) |

By default no limit is set. A zero length reset a limit.

## ◆ spellCheckSettings()

LocalizeContainer Digikam::DPlainTextEdit::spellCheckSettings | ( |  | ) | const

See LocalizeContainer class for details.

## ◆ text()

QString Digikam::DPlainTextEdit::text | ( |  | ) | const

If ignored or accepted characters masks are set, text is filtered accordingly.
