wxCmdLineArg Class Reference

#include <wx/cmdline.h>

Detailed Description

The interface wxCmdLineArg provides information for an instance of argument passed on command line.

Example of use:

wxCmdLineParser parser;

for (wxCmdLineArgs::const_iterator itarg=parser.GetArguments().begin();
                                   itarg!=parser.GetArguments().end();
                                   ++itarg)
{
    wxString optionName;
    switch (itarg->GetKind())
    {
    case wxCMD_LINE_SWITCH:
        if (itarg->IsNegated()) {
        }
        else {
        }
        break;

    case wxCMD_LINE_OPTION:
        // assuming that all the options have a short name
        optionName = itarg->GetShortName();

        switch (itarg->GetType()) {
            case wxCMD_LINE_VAL_NUMBER:
                // do something with itarg->GetLongVal();
                break;

            case wxCMD_LINE_VAL_DOUBLE:
                // do something with itarg->GetDoubleVal();
                break;

            case wxCMD_LINE_VAL_DATE:
                // do something with itarg->GetDateVal();
                break;

            case wxCMD_LINE_VAL_STRING:
                // do something with itarg->GetStrVal();
                break;
        }
        break;

    case wxCMD_LINE_PARAM:
        // do something with itarg->GetStrVal();
        break;
    }
}

With C++11, the for loop could be written:

for (const auto &arg : parser.GetArguments()) {
    // working on arg as with *itarg above
}

Member Function Documentation

virtual const wxDateTime& wxCmdLineArg::GetDateVal ( ) const

pure virtual

Returns the command line argument value as a wxDateTime.

Note

This call works only for wxCMD_LINE_VAL_DATE options

virtual double wxCmdLineArg::GetDoubleVal ( ) const

pure virtual

Returns the command line argument value as a double.

Note

This call works only for wxCMD_LINE_VAL_DOUBLE options

virtual wxCmdLineEntryType wxCmdLineArg::GetKind ( ) const

pure virtual

Returns the command line argument entry kind.

Note

Parameters can only be retrieved as strings, with GetStrVal()

wxCmdLineEntryType, GetType()

virtual wxString wxCmdLineArg::GetLongName ( ) const

pure virtual

Returns the command line argument long name if any.

Note

This call makes sense only for options and switches

virtual long wxCmdLineArg::GetLongVal ( ) const

pure virtual

Returns the command line argument value as a long.

Note

This call works only for wxCMD_LINE_VAL_NUMBER options

virtual wxString wxCmdLineArg::GetShortName ( ) const

pure virtual

Returns the command line argument short name if any.

Note

This call makes sense only for options and switches

virtual const wxString& wxCmdLineArg::GetStrVal ( ) const

pure virtual

Returns the command line argument value as a string.

Note

This call works only for wxCMD_LINE_VAL_STRING options and parameters

virtual wxCmdLineParamType wxCmdLineArg::GetType ( ) const

pure virtual

Returns the command line argument parameter type.

Note

This call makes sense only for options (i.e. GetKind() == wxCMD_LINE_OPTION).

wxCmdLineParamType, GetKind()

virtual bool wxCmdLineArg::IsNegated ( ) const

pure virtual

Returns true if the switch was negated.

Note

This call works only for switches.
