QBuffer test

About

Qt example how to use QBuffer.

Compiling

git clone https://github.com/AndreiCherniaev/QBuffer_test.git && cd QBuffer_test
mkdir build/
cmake -S src/ -B build/ --fresh # qt-cmake -S src/ -B build/ -DCMAKE_BUILD_TYPE=Release --fresh
cmake --build build/ --parallel

Run

Before start open source code and uncomment A) and comment B),C) and rebuild

A) Open-close way

buf.close();
buf.open(QBuffer::WriteOnly);

Log

Writer;size;1;1;B;isNull;false;buf_cnt;1
myflush;size;1;1;B;isNull;false
myflush;size;1;1;B;isNull;false
Writer;size;1;1;B;isNull;false;buf_cnt;1
~;size;1;1;B;isNull;false;buf_cnt;1

B) Clear way

Then open source code and comment A),C) and uncomment B) and rebuild

buf.buffer().clear();

Log

Writer;size;1;1;B;isNull;false;buf_cnt;1
myflush;size;1;1;B;isNull;false
myflush;size;0;0;B;isNull;true
Writer;size;2;2;B;isNull;false;buf_cnt;1
~;size;2;2;B;isNull;false;buf_cnt;1

C) Seek way

Then open source code and comment A),B) and uncomment C) and rebuild

buf.seek(0L);

Log

Writer;size;1;1;B;isNull;false;buf_cnt;1
myflush;size;1;1;B;isNull;false
myflush;size;1;1;B;isNull;false
Writer;size;1;1;B;isNull;false;buf_cnt;1
~;size;1;1;B;isNull;false;buf_cnt;1
