listbox

[maitrelame2]

I want to open a music with my mp3 player but I need to get the filename+the repertory...

Code: Select all

{
                 listbox->addItem(L"Open a sound");
                 env->addFileOpenDialog(L"Please selecte a sound");
                 return true;
              }

I juste to get a string like ..\media\my.mp3...
Could you help plz

[roxaz]

i dont know how to implement it technicaly, but the idea should be like this: read sounds directory, show all files using for loop. for more info read documentatuon. http://msdn.microsoft.com/ if you are using vc++

[bitplane]

device->getFileSystem()->getAbsolutePath("./some/thing.ok");
returns something like "c:\\path\\to\\some\\thing.ok"
is that what you meant?

[maitrelame2]

Not realy I mean that I want to select a file in listbox, and after get the directorie and the file name like :

I go on C:\-->Programm files --> musique --> lol.mp3
And clic on ok
then i get a string that give me : C:\Programm files\musique\lol.mp3
Then I send it to FSOUND_STREAM play(string song);
so it play the sound I select before...

[bitplane]

then you want the absolute path? in that case, getAbsolutePath is what you need

[maitrelame2]

Thank you but how to store in a string ?

[roxaz]

by typecasting maybe

(roxaz go learn c++ and read more thoroughly)

core::stringc longname = getAbsolutePath(filename);
const char* path = longname.c_str();

But beware that char* can be complex to handle correctly. Better use stringc throughout your program and only pass the c_str() to system and Irrlicht functions where necessary.

my bad

[maitrelame2]

I doesn't work...

Code: Select all

              if (id == 103)
              {
                 listbox->addItem(L"Ouvrir un morceau ");
                 env->addFileOpenDialog(L"Veuillez choisir un fichier");
                 std::string filename;
                 core::stringc longname = getAbsolutePath(filename); 
                 return true;
              }

message devcpp : 'getAbsolutePath' undeclared {first use this function}
I think that's because I use irrlicht 1.1...
I don't realy want to change with irrlicht 1.2, because the loop is not the same...
I receive the error :
Filename undeclarred...

[hybrid]

Hehe, maybe you also need a C++ freshup? The longfilename was just an example how to store the result in a string. If you make this string local to the if block it will of course be gone after the block.
More problems: bitplane already gave you the complete method call path for getAbsolutePath, so use that one. But be sure that your device pointer is valid.
Just adding the FileDialog is not enough. You have to get the filename from the dialog and maybe close the dialog. And using std::string is not necessary at all.

@roxaz: Never mind, but some of your suggestions are really dangerous. So take your time and develop your skills with Irrlicht

[maitrelame2]

I don't understand can you just writte two lines of codes for show it to me plz...

[zeno60]

I don't understand can you just writte two lines of codes for show it to me plz...

I don't understand why someone can't learn a language before they attempt to use it...

[BlindSide]

getFileSystem()->getAbsolutePath("./some/thing.ok");

The function is part of the filesystem class. I suggest you do as zeno says...

And why are you using "filename"? Delete that one...

Actually forget all of that and just read a C++ book . Because you will run into 100 more errors anyway if you don't know what your doing.

Ok dont read a C++ book actually its better to have a look through the code for the meshviewer example.

umm yea more C++ experiance would defanatly help.

Code: Select all

if (id == 103) 
              { 
                 listbox->addItem(L"Ouvrir un morceau "); 
                 env->addFileOpenDialog(L"Veuillez choisir un fichier"); 
                 std::string filename; 
                 core::stringc longname = getAbsolutePath(filename); 
                 return true; 
              }

this is in the local scope!!!

you must add:

Code: Select all

IGUIListBox* listbox = 0;  //<-- declarations for variables

//and this

IGUIEnvironment* env = 0; //<-- this too is needed since this is in local scope 

and this: getAbsolutePath(filename); is a function not a variable you you must also declare the ACTUAL FILE NAME YOU WANT not just filename.

i.e. std::string = NAME_OF_FILE_HERE;
then getAbsolutePath( "NAME_OF_FILE" )


within your braces so listbox is declared in the function.

this has nothing to do with irrlicht!!!

this is proper C++ practice.

a C++ tip, when you have a local function such as this, unless you are using a class to define all your varibles, you must explicitly declare the functions you want to use. basic C++ knowledge tells us that unless declared public with a class, functions in the LOCAL SCOPE have no access to functions in the GLOBAL SCOPE until declared within the fuction.
