Remarks

Pops up a file selector box. In Windows, this is the common file selector dialog. In X, this is a file selector box with somewhat less functionality. The path and filename are distinct elements of a full file pathname. If path is "", the current directory will be used. If filename is "", no default filename will be supplied. The wildcard determines what files are displayed in the file selector, and file extension supplies a type extension for the required filename. Flags may be a combination of wxOPEN, wxSAVE, wxOVERWRITE_PROMPT, wxHIDE_READONLY, wxFILE_MUST_EXIST, wxMULTIPLE or 0.

Both the X and Windows versions implement a wildcard filter. Typing a filename containing wildcards (*, ?) in the filename text item, and clicking on Ok, will result in only those files matching the pattern being displayed. The wildcard may be a specification for multiple types of file with a description for each, such as:

     "BMP files (*.bmp)|*.bmp|GIF files (*.gif)|*.gif"

wxString GetFilename() const

Returns the default filename.

### wxFileDialog::GetFilenames

void GetFilenames(wxArrayString& filenames) const

### wxFileDialog::GetPaths

void GetPaths(wxArrayString& paths) const

Fills the array paths with the full paths of the files chosen. This function should only be used with the dialogs which have `wxMULTIPLE` style, use GetPath for the others.

### wxFileDialog::GetStyle

long GetStyle() const

Returns the dialog style.

### wxFileDialog::GetWildcard

wxString GetWildcard() const

Returns the file dialog wildcard.

### wxFileDialog::SetDirectory

void SetDirectory(const wxString& directory)

Sets the default directory.

### wxFileDialog::SetFilename
