How to ignore wxCmdLineParser ? Topic is solved

[saifcoder]

I want parse command arguments myself, i can get correctly argc and argv

Code: Select all

bool MyApp::OnInit()
{
    ... wxApp::argc ;
    ... wxApp::argv[2] ;
}

but i get wxCmdLineParser error message :

Unexpected paramter 'TestArg1'
Usage: minimal [/h] [--verbose]
/h, --help show this help message,
--verbose generate verbose log message.

i read many topics, google.., but i didn't find a way to ignore wxCmdLineParser

How to ignore command arguments Parser (wxCmdLineParser) please ?

Thanks,

Don't call wxApp::OnInit() from inside your overloaded MyApp::OnInit().

[saifcoder]

Thank you for your replay Doublemax, but i didn't call wxApp::OnInit() from MyApp::OnInit() !

Where you see this call ? ^_^

I get this error because i run the app with test arguments (MyApp.exe ArgTest1 ArgTest2...), so the command arguments Parser (wxCmdLineParser) return unknow argument "ArgTest1"

I know, i can use the wxCmdLineParser... but is there i way to ignore this ? i want use my personal parser method !

Thank you,

I didn't see it, but it assumed is was there, because that's where the command line parsing happens. And removing it usually gets rid of the message.

Which platform and wxWidgets version are you using?

Try overriding wxAppConsole::OnCmdLineError(...)

I am using Github master branch (wxWidgets 3.1.1), on Windows (TDM GCC) right now, but i m sure the same result on Linux and Mac..

Code: Select all

class MyApp : public wxApp
{
    public:

	MyApp();
	~MyApp();
	virtual bool OnInit();
        virtual int OnExit();

	private:
		DECLARE_NO_COPY_CLASS(MyApp)
};

bool MyApp::OnInit()
{
	if (!wxApp::OnInit())
		return false;

	if (wxApp::argc > 1)
	{
		wxString Arg = wxApp::argv[2] ...
	}

    return true;
}

Thanks,

Yes, wxAppConsole::OnCmdLineError() with true return did it, but after showing error message ! Waw!

Unexpected parameter 'TestArg1'

Then App continue in normal way because wxAppConsole::OnCmdLineError() return true, so how to completely prevent wxAppConsole::OnCmdLineError() to show error log ?

[doublemax]

Code: Select all

   if (!wxApp::OnInit())
      return false;

What's that? You said you didn't call it.

Set a breakpoint at the beginning of MyApp::OnInit and single step through it. I can't think of any other place where the command line parsing could happen.

Oh! Not me, but someone else*.. what a bad programmer.., but don't worry i remove it, now with OnCmdLineError() work correctly !

Thank you Doublemax, you save my day ^_^
