Open With does not set argv

[M_is_just_2_Ns]

I am creating an application for modifying specific files.
I want the users to be able to just "open with... <my Application>" such a file.
As far as I understand, that would increment wxApp::argc and add the file's path to wxApp::argv, so that the following code should display the path to the chosen file:

Code: Select all

bool App::OnInit()
{
	wxMessageBox(std::string(argc[1]));
	// other stuff...
	return true;
}

And it does work when passing a parameter through the terminal.
But once I put it in a macOS Application-Bundle and actually used open-with on it, an Error occurred(and argc is 1).
Why is this? Am I doing something wrong? Any help is appreciated.

Let's see what the documentation says:

wxChar** wxAppConsole::argv

Command line arguments (after environment-specific processing).

Under Windows and Linux/Unix, you should parse the command line arguments and check for files to be opened when starting your application. Under macOS, you need to override MacOpenFiles() since command line arguments are used differently there.

I have implemented that MacOpenFiles(...) is called after OnInnit().
Why is the timing of that and how can I know if the function will ever be called (so that I can know if I should ask the user to choose a file manually)?
