... xxxx seems to be the number of characters in the edit widget.

The warning apparently is associated with clearing the text document, where QtSpell doesn't recognize that the document is empty. (This is a guess.)

Repro: in gImageReader scan a (simple) document in text (not HOCR) mode, and then clear the scan in the Output window. At least that works for me always.

Is the off-by-one case noted in the comments in checkSlotRange either (now that that might be fixed?) the cause, or is there another special case to work around?

Workaround in gImageReader::OutputEditorText::clear (somewhere near line 330): add the setUndoRedoEnabled calls below:

			return false;
		}
	}
	m_spell.setUndoRedoEnabled(false); // added for workaround
	ui.plainTextEditOutput->clear();
	m_spell.setUndoRedoEnabled(true); // added for workaround
	m_spell.clearUndoRedo();
	ui.plainTextEditOutput->document()->setModified(false);

I'm using version 0.8.4 (a8f702b) on Debian and I can't get spell check to work. When I input words into a QTextEdit it doesn't highlight misspelled words. I have the needed dictionaries installed. Here is my code:

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QTextEdit>
#include <QtSpell.hpp>

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    // create a QtSpell::TextEdit instance
    QtSpell::TextEditChecker checker;

    // attach to a QTextEdit or QPlainTextEdit
    QTextEdit* textEdit = new QTextEdit(this);
    checker.setTextEdit(textEdit);
}

First of all, it works perfectly and I'm very happy with it. I would also like to be able to check if undo and redo are avaiable via isUndoAvaiable() and isRedoAvaiable(). I also noticed that with older Qt versions < 5.15 an error occurs when running cmake:

CMake Error at CMakeLists.txt:65 (QT_ADD_TRANSLATION):
  Unknown CMake command "QT_ADD_TRANSLATION".

After changing it to

IF(NOT Qt6_FOUND)
QT5_ADD_TRANSLATION(qtspell_QM ${qtspell_TS})
ELSE(NOT Qt6_FOUND)
QT6_ADD_TRANSLATION(qtspell_QM ${qtspell_TS})
ENDIF(NOT Qt6_FOUND)

it worked again. I would be very grateful if you could change that. Nevertheless, thank you in advance.

In Qt 5.11, QT5_USE_MODULES macro is deprecated. This makes compilation to fail.

Not really making a pull request, but just a simple patch code to fix the issue. Feel free to merge.

When QtSpell is built with enchant 1.6.1, build fails due to undefined reference to 'libintl_*'.

In the past, problem did not occur because libintl is included in enchant's dependency.
enchant dropped that dependency in 1.6.1 so now nobody is looking for linintl.

Here is a part of build log with enchant 1.6.0.

QtSpell directly calls libintl so it should be explicitly linked in QtSpell's CMakeFiles.

Description of problem:

Some language names do not display correctly.

Version-Release number of selected component:

• qtspell-0.8.5
• gImageReader-3.3.0 (Qt version)

Steps to Reproduce (Fedora 29):

1. Install gimagereader-qt5.
2. Install hunspell-*, or at least hunspell-oc.
3. Open gimagereader-qt5.
4. Add an image from file or take a screenshot.
5. Select: OCR mode: Plain text.
6. Click: Recognize all.
7. Open the context menu in the text box in the output pane.
8. Select Languages.

Actual results:

Occitan (post 1500); Proven�al

Expected results:

Occitan (post 1500); Provençal

Additional info:

Conversion to Latin1 causes loss of information about some characters.

Explanation:

You should replace these lines:

name = QString::fromUtf8(dgettext(ISO_639_DOMAIN, name.toLatin1().data()));

name = QString::fromUtf8(dgettext(ISO_3166_DOMAIN, name.toLatin1().data()));;

with these:

name = QString::fromUtf8(dgettext(ISO_639_DOMAIN, name.toUtf8().constData()));

name = QString::fromUtf8(dgettext(ISO_3166_DOMAIN, name.toUtf8().constData()));

or these:

name = QString::fromLocal8Bit(dgettext(ISO_639_DOMAIN, name.toLocal8Bit().constData()));

name = QString::fromLocal8Bit(dgettext(ISO_3166_DOMAIN, name.toLocal8Bit().constData()));

This bug report is related to submitting my flatpak package to the Flathub repository.
manisandro/gImageReader#396
flathub/flathub#810

I noticed that two-character language codes ("en", "ru" ,etc.) are not translated in Qt version of gImageReader.

It seems like the problem is that Codetable::lookup, in contrast to gtksell, doesn't perform lookup for such codes at all.

Compare https://sourceforge.net/p/gtkspell/gtkspell/ci/master/tree/gtkspell/gtkspell-codetable.c#l199 with

I'm trying to add spell checking for qTox messenger with this library. When using QtSpell from master, on GNU/Linux, I'm getting this warning:

:0 : Warning: Failed to load dictionary: 
:0 : Warning: Failed to load dictionary: 
:0 : Warning: Failed to load dictionary: 

Code is very simple:

msgEdit = new ChatTextEdit();
QtSpell::TextEditChecker checker;
checker.setTextEdit(msgEdit);

What could be causing this?

I think that this is the same error as with enchant 1.6: https://github.com/manisandro/qtspell/issues/2
