Greetings to all on the continuation of the topic of self-contained snap packages. In today's part, we will discuss how to configure the application so that it can be launched not only in the console, but also in the graphical environment (KDE, GNOME, XFCE, and so on).

Good day.

I create a Duty schedule application for our technical support hotline, using Qt + MySQL.
For each month it is necessary to monthly fill in the calendar table containing the date and sign of the day off or working day..

In connection with a small question on the forum and slightly free time today. I will answer in the form of an article on how to highlight in QTextEdit all the words that need to be found in this text.

To implement this functionality, you will need to use QSyntaxHighighter , as if writing a syntax highlighting code. Here, by the way, is an example of syntax highlighting for HTML .

And here's an example.

I propose to write a small application that will have two subdirectories. One of which will compile the executable file, and the second will contain a statically linked library.

As a result, the project will look like this.

I would like to welcome everyone to the continuation of the topic concerning a self-sufficient snap package. A lot of time has passed since the publication of the previous article in which I began to acquaint you with snap technology from my experience and application. All the fault of time, business, and laziness, of course, was also present) But we will now continue the topic)

After lengthy attempts to cope with JavaScript and its glitches in different browsers, I refused to write a WYSIWYG editor.

Thanks to the community (a survey was conducted in the public in VKontakte), which also shares my point on this matter. Namely, it is better to add a normal Markdown editor than Wysiwig.

Mysql по умолчанию не ставится в SuSe. Вместо него устанавливается MariaDB Разницы никакой пока не ощутил.

Итак сервер установлен. Проверим запущен ли он в системе. За что мне нравится SuSE с первого знакомства так это Yast. Yast-Система-Управление службами Находим mariadb устанавливаем запуск при загрузке и запускаем сервис. Сервис запустился. Появился файл /var/log/mysql/mysql.log В нем видим что сервис запустился и доступен только с 127.0.0.1 А хотелось бы работать с базой и с других машин.

Открываем файл /etc/my.cf Комментируем строку

     #bind-address = 127.0.0.1

Перезапускаем сервис.

 service mariadb restart

Теперь можно соединятся с сервером ото всюду.

Очередная переустановка ОС в связи с заменой железа.

Установил Suse Leap 15.

Согласно статьи устанавливаем пакеты для разработки и сам Qt.

Делаем для проверки простейший  проект. Пытаемся собрать. Немного огорчаемся ибо такая ошибка возникает.

can't find -lGL error

Получается нет библиотеки libGL.  Ее предоставляет  пакет Mesa-libGL-devel и он почему-то не входит в комплект devel_basis.

Устанавливаем...

zypper in Mesa-libGL-devel

Проект собрался и приложение запустилось.

A small addition to the article on the use of boost::program_options .

In this appendix I will describe how to use enum enums. Because immediately they do not work. By default, boost::program_options work only with basic types and some types from the standard library, for example std::string .

When developing a site to automate the deployment process, I wrote several bash scripts.

To customize the behavior of scripts, I use the transfer of arguments, which are handled in the bash script by the getopts library.
