C++ polymorphism with GUI example
Video on youtube, how the GUI works
It is example of polymorphism in C++ with GUI. See polymorph_learning_try3.cpp.
It has interface view.h that is common interface for gui widget objects button and checkbox.
check_mouse function is fully virtual. Also it has virtual distructor.
It has container of polymorphic objects:
view** views_all;
for (int view_count = 0; view_count < N_VIEWS; view_count++)
{
views_all[view_count]->check_mouse(image, x, y, event);
}
Function pointers were used for callbacks.
OpenCV was used for graphics.
It was made in visual studio comunity 2019.
I had opencv compiled before. I added msvcp120d.dll, msvcr120d.dll, msvcp120.dll, msvcr120.dll files.
