I'm following the example at "Foundations of GTK+" where it explains how to get a folder's content.
I'm using this code to store each filename inside a vector:

Code: (C++)
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15	GDir* dir = g_dir_open( "fonts/", 0, NULL ); const gchar* file; std::vector<char> files; if( !g_file_test( "fonts/", G_FILE_TEST_IS_DIR ) ) g_error( "Error: There is no \"fonts\" directory!" ); while( ( file = g_dir_read_name( dir ) ) ) { std::cout << "File:" << file << std::endl; files.push_back( (char)file ); } g_dir_close( dir );

while cout prints ok each filename, doesn't stores correctly into files vector. It seems like I'm storing the address instead the value of file because if I remove g_dir_close(dir) I get almost valid values.

I say almost 'cause what I'm just getting the last filename found repeated number_of_files_on_folder times.

What I'm doing wrong???[/code]

Use the following code instead. This way, your string pointer is not overwritten each time.

Code: (Plaintext)
1	files.push_back( g_strdup (file) );
