get a wxArrayString as a wxString

Post by MoonKid » Thu Apr 06, 2006 3:58 pm

Example: There are some items in a wxArrayString. I want them all in one string seperated by '\n'. There is now standard way implemented yet.

please see http://forums.wxwidgets.org/viewtopic.php?t=7492 for the previous discussion.

There are some ways I think
1. a cast operator in wxArrayString so it is possible to handle it like a wxString

2. ask wxArrayString for a string of all items (GetAsString())

3. a wxString ctor wxString::wxString(wxArrayString)

4. an other solution?


For me I choose the #2 and patched the wxArrayString class.

What is the official way to get such patches in the official wxWidget source?

Code: Select all

wxString s = "";

for(int i=0;i<arr_str->GetCount();i++)
{
   s << arr_str->Item(i);

   // Don't draw a \n at the end of the string
   if(i != arr_str->GetCount()-1)
       s << '\n';
}
There ya go. It's so easy I don't see why it needs to be written into the class.

THATs why I want it in the class. Because I do not want to write such easy things every time!

Make it a function. You only have to write it once.

But what is the use of such a function ?
If you want to write it to file you usually use
a stream, and not a string. So, wxTextCtrl
also has a streaminterface.

For what and how often do you use such a function ?

to #1: I think thats the worst way, it could leed to unexpected behavoir in your code.

to #2&3: Hm, could be a way, but how often is this needed ? And wheres the sense for it ?
Hm, and for int, float etc ?
Maybe it would make more sense to implement a templatefunction:

Code: Select all

template<class type>wxString Array2Type(type& array,wxString delimeter)
{
// do the stuff
}

MoonKid, I don't know if you read the reactions that are posted thoroughly or not, but I explained WHY it cannot be part of the class here;
