'C++ execute bat/sh file and choose variant from UI
Faced a problem during the implementation of the launch of the script under the UI in C++ with SDL2.
The task is that a script is launched by pressing a button in the UI. Further, the option should be selected in the script (entering the number in the console, in the script), but I cannot do this by pressing the button.
The script is run as system("script.bat")
through a separate thread to avoid blocking the UI.
Further, according to the script's logic, a number should be entered and enter is pressed, but here I don’t know how to do it. Tried system("echo 1\n")
and std::cout << "1" << std::endl
doesn't work.
Maybe I should implement this in another way?
Buttons code:
if (ui::Button().text("Start script"))
{
m_thread = std::thread([this]() { // in thread to avoid blocking the UI
system("script.bat");
});
}
if (ui::Button().text("Variant 1"))
{
system("echo 1\n");
std::cout << 1 << std::endl;
}
