Command line arguments in wxWidgets

Question

Is there a way I can read the command line arguments passed into a C++ wxWidgets application? If so, could you please provide an example of how to do so.

Answer 1

In plain C++, there is argc and argv. When you are building a wxWidgets application, you can access these using wxApp::argc, wxApp::argv[] or wxAppConsole::argc, wxAppConsole::argv[]. Note that wxApp is derived from wxAppConsole, so either works depending on if you have a console app or GUI app. See wxAppConsole

IMPLEMENT_APP(MyApp)

bool MyApp::OnInit() {
// Access command line arguments with wxApp::argc, wxApp::argv[0], etc.
// ...
}
