wxMultiChoiceDialog(wxWindow* parent, const wxString& message, const wxString& caption, int n, const wxString* choices, long style = wxCHOICEDLG_STYLE, const wxPoint& pos = wxDefaultPosition)

wxMultiChoiceDialog(wxWindow* parent, const wxString& message, const wxString& caption, const wxArrayString& choices, long style = wxCHOICEDLG_STYLE, const wxPoint& pos = wxDefaultPosition)

Constructor taking an array of wxString choices.

Parameters

parent

Parent window.

style

A dialog style (bitlist) containing flags chosen from standard dialog styles and the following:

wxOK | Show an OK button.
wxCANCEL | Show a Cancel button.
wxCENTRE | Centre the message. Not Windows.

The default value is equivalent to wxDEFAULT_DIALOG_STYLE | wxRESIZE_BORDER | wxOK | wxCANCEL | wxCENTRE.

Remarks

Use wxMultiChoiceDialog::ShowModal to show the dialog.

wxPython note: For Python the two parameters `n` and `choices` are collapsed into a multi parameter `choices` which is expected to be a Python list of strings.

wxPerl note: In wxPerl there is just an array reference in place of `n`.
