OVERVIEW<\/strong><\/p>\n\n\n\n

The wxArrayString is a class which acts as a wrapper for the standard vector class in C++. This enables us to create a dynamic list of wxStrings and then do normal array operations with them. <\/p>\n\n\n\n

SAMPLE CODE<\/strong><\/p>\n\n\n\n

Given below is sample code which uses wxArrayString in three different ways.<\/p>\n\n\n

\n#include <wx\/wxprec.h>\n#ifndef WX_PRECOMP\n#include <wx\/wx.h>\n#endif \/\/ WX_PRECOMP\n#include <wx\/string.h>\n#include <wx\/arrstr.h>\n\nvoid printArr(wxArrayString* arr) {\n  for(size_t i=0; i < arr->GetCount(); i++) {\n        wxString val = arr->Item(i);\n        wxPuts(val);\n    }\n}\n\nint main(int argc, char **argv) {\n    wxInitialize();\n    wxPuts("Starting..");\n\n    wxArrayString *arr1 = new wxArrayString();\n    arr1->Add("one"); arr1->Add("two"); arr1->Add("three");\n    wxString retVal = "size of arr1=" + wxString::Format(wxT("%zu"), arr1->GetCount());\n    wxPuts(retVal);\n    printArr(arr1);\n    wxPuts("Sorting in ascending order");\n    arr1->Sort();\n    printArr(arr1);\n    arr1->Clear();\n    retVal = "size of arr1 after clearing=" + wxString::Format(wxT("%zu"), arr1->GetCount());\n    wxPuts(retVal);\n\n    wxArrayString arr2;\n    arr2.Alloc(10);\n    for(size_t i=0; i < 20; i++) {\n        wxString s = wxString::Format(wxT("%zu"), i);\n        arr2.Add(s);\n    }\n    retVal = "size of arr2 =" + wxString::Format(wxT("%zu"), arr2.GetCount());\n    printArr(&arr2);\n    int searchElem = arr2.Index(wxT("3"));\n    retVal = "found '3' in element " + wxString::Format(wxT("%d"), searchElem);\n    wxPuts(retVal);\n    arr2.RemoveAt(searchElem);\n    searchElem = arr2.Index(wxT("3"));\n    retVal = "location of '3' after removal " + wxString::Format(wxT("%d"), searchElem);\n    wxPuts(retVal);\n    arr2.Shrink();\n\n    wxString test = wxT("one,two,three,four,five");\n    wxPuts("String values:" + test);\n    wxArrayString arr3 = wxSplit(test, wxT(','));\n    printArr(&arr3);\n\n    wxPuts("Ending..");\n\n    wxUninitialize();\n    return 1;\n}\n\n\n\n<\/pre><\/div>\n\n\n
