[Cleves]

anyone?^^

From the way the documentation reads, this is not currently possible.

You could make your own File list using the IGUIListBox or your own handcrafted interface.

Can someone plz show me how to get the filename of the selected file?
i can't get it working

[saigumi]

wchar_t* FileName = myGUIFileOpen->getFilename();

[Cleves]

That's exaclty what i have done but he writes violation accsess:
here is my code:

env->addFileOpenDialog(L"Please choose a file.");
IGUIFileOpenDialog* opendlg=0;
const wchar_t* FileName = opendlg->getFilename();
Thanks

Yeah because opendlg is a pointer pointing to nothing, so of course you will get a access violation, when you are trying to derefrence it, and the program can't access that spot in memory (0 == NULL).
.
I haven't used the UserInterface Classes yet, but i believe you have to do something like this:

Code: Select all

IGUIFileOpenDialog* opendlg = env->addFileOpenDialog(L"Please choose a file.");

const wchar_t* FileName = opendlg->getFilename();

IT was me again. I am getting tired of having to do these double posts everytime I forget to login

Anyway it was me that posted the above. So please tell me if it works, that way I don't have to scratch my head trying to get it to work when I need it

[Cleves]

Yes, it works now.Thank you.

[Cleves]

mmm when i'm trying to print out what is inside FileName it comes out as 0x00035.How can i know the name of the file?
What i'm trying to do is that the user picks up a mesh file(3ds,obj,etc)
and it loads it and shows it up.Is it possiable?

Thanks

[Sfin]

I think you might need to dereference FileName with *

so

cout << *FileName;

[Cleves]

Well i tried what you said but he returnes 0 even if i did choose a file.
Here is my code:

IGUIFileOpenDialog* opendlg = env->addFileOpenDialog(L"Please choose a file.");
const wchar_t* FileName = opendlg->getFilename();
ofstream fout("output.txt");
fout << *FileName << "\n";

[saigumi]

Could the problem be that the user hasn't been able to select a file in the split second between opening the window and it checking what is being selected?

This isn't VB where the program will wait for the dialog box to be dealt with.

You would have to do the getFileName() during your event handler.

Code: Select all

if (event.EventType == EET_GUI_EVENT){
   if (event.GUIEvent.EventType ==EGET_FILE_SELECTED){
      const wchar_t* FileName = opendlg->getFilename(); 
   }
}

[Cleves]

Yep it works but i'm still getting numbers then the name of the file

...but i'm still getting numbers then the name of the file

hm could it be that you use a char outputstream instead of a wchar??
I'm not sure if that matters with C++?
I wouldd try to convert the wchar string to a normal character string and then output it...

Code: Select all

std::string to_string(const wchar_t* msg){
  std::locale loc1 ( "english" );
  char str2 [255];
  std::use_facet<std::ctype<wchar_t> > ( loc1 ).narrow( msg, msg + wcslen(msg), 'X', &str2[0] );
  str2[wcslen(msg)] = '\0';
  std::string result(str2);
  return result;
}

tell me if it works
cheers
