Usage

In its initial implementation only CMake tool is considered. To use the library in your project, you have:

1. Add the library as a submodule (or any kind of folder in your machine)

   git submodule add https://github.com/arsdever/qspdlog.git
   

2. Add the library to your CMake project

   add_subdirectory(qspdlog)
   

3. Add the library to your target

   target_link_libraries(${PROJECT_NAME} qspdlog::lib)
   

4. Include the interface header into the source file where you want to instantiate the widget

   #include <qspdlog/qspdlog.h>
   

5. Instantiate the widget, register loggers and show the widget

   QSpdLogWidget* widget = new QSpdLogWidget();
   
   auto sink = widget->sink();
   // register the sink to whatever logger you want
   
   widget->show();
   

A complete example can be found in the sample folder.

Note: In the sample it’s considered that you already added the library as a submodule.
