All Implemented Interfaces:

Adaptable
```
public class FileDialog

```
Instances of this class allow the user to navigate the file system and select a file name. The selected file will be uploaded to the server and the path made available as the result of the dialog.

Styles:

MULTI

Events:

(none)

The OPEN style is applied by default and setting any other styles has no effect.

IMPORTANT: This class is intended to be subclassed only within the SWT implementation.

```
public FileDialog(Shell parent)
```
    Constructs a new instance of this class given only its parent.
    Parameters:
    
    parent - a shell which will be the parent of the new instance
    
    Throws:
    
    java.lang.IllegalArgumentException -
    
    ERROR_NULL_ARGUMENT - if the parent is null
    
    SWTException -
    
    ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the parent
    
    ERROR_INVALID_SUBCLASS - if this class is not an allowed subclass

```
public FileDialog(Shell parent,
                  int style)
```
    Constructs a new instance of this class given its parent and a style value describing its behavior and appearance.
    The style value is either one of the style constants defined in class SWT which is applicable to instances of this class, or must be built by bitwise OR'ing together (that is, using the int "|" operator) two or more of those SWT style constants. The class description lists the style constants that are applicable to the class. Style bits are also inherited from superclasses.
    Parameters:
    
    parent - a shell which will be the parent of the new instance
    
    style - the style of dialog to construct
    
    Throws:
    
    java.lang.IllegalArgumentException -
    
    ERROR_NULL_ARGUMENT - if the parent is null
    
    SWTException -
    
    ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the parent
    
    ERROR_INVALID_SUBCLASS - if this class is not an allowed subclass

  - getFileName
```
public java.lang.String getFileName()
```
    Returns the path of the first file that was selected in the dialog relative to the filter path, or an empty string if no such file has been selected.
    
    Returns:
    
    the relative path of the file
  - getFileNames
```
public java.lang.String[] getFileNames()
```
    Returns a (possibly empty) array with the paths of all files that were selected in the dialog relative to the filter path.
    
    Returns:
    
    the relative paths of the files
  - setFilterExtensions
```
public void setFilterExtensions(java.lang.String[] extensions)
```
    Set the file extensions which the dialog will use to filter the files it shows to the argument, which may be null.
    An extension filter string must be of the form ".extension".
    
    Parameters:
    
    extensions - the file extension filter
    
    Since:
    
    3.2
  - getFilterExtensions
```
public java.lang.String[] getFilterExtensions()
```
    Returns the file extensions which the dialog will use to filter the files it shows.
    
    Returns:
    
    the file extensions filter
    
    Since:
    
    3.2
  - setClientFiles
```
public void setClientFiles(ClientFile[] files)
```
    Sets initial client files to be uploaded. The upload of these files will start immediately after opening the dialog. Hence, this method must be called before opening the dialog.
    A user can drag and drop files from the client operating system on any control with a drop listener attached. In this case, the client files can be obtained from the ClientFileTransfer object. This FileDialog can then be used to handle the upload and display upload progress.
    
    Parameters:
    
    files - an array of client files to be added to the dialog
    
    Since:
    
    3.1
  - setUploadSizeLimit
```
public void setUploadSizeLimit(long limit)
```
    Sets the maximum upload size in bytes. If upload size is bigger it will be interrupted. A value of -1 indicates no limit.
    
    Parameters:
    
    limit - the maximum upload size in bytes
    
    Since:
    
    3.3
    
    See Also:
    
    UploadSizeLimitExceededException
  - getUploadSizeLimit
```
public long getUploadSizeLimit()
```
    Returns the maximum upload size in bytes. The default value of -1 indicates no limit.
    
    Since:
    
    3.3
  - setUploadDirectory
```
public void setUploadDirectory(java.io.File directory)
```
    Set the directory where the files should be uploaded to. If no directory is set or it is set to null a temporary directory is used.

    directory - the directory to upload to
    
    Since:
    
    3.7
  - getUploadDirectory
```
public java.io.File getUploadDirectory()
```
    Returns the directory where the files should be uploaded to, or null when a temporary directory is used.
    
    Since:
    
    3.7
  - setUploadTimeLimit
```
public void setUploadTimeLimit(long limit)
```
    Sets the maximum upload duration in milliseconds. If upload takes longer it will be interrupted. The default value of -1 indicates no limit.
    
    Parameters:
    
    limit - the maximum upload duration in milliseconds
    
    Since:
    
    3.3
    
    See Also:
    
    UploadTimeLimitExceededException
  - getUploadTimeLimit
```
public long getUploadTimeLimit()
```
    Returns the maximum upload duration in milliseconds. The default value of -1 indicates no limit.
    
    Since:
    
    3.3
  - getExceptions
```
public java.util.List<java.lang.Exception> getExceptions()
```
    Returns a list with exceptions thrown during the file upload. Will never return null.
    
    Since:
    
    3.3
    
    See Also:
    
    UploadSizeLimitExceededException, UploadTimeLimitExceededException
  - open
```
public java.lang.String open()
```
    Makes the dialog visible and brings it to the front of the display.
    RAP Note: This method is not supported when running the application in JEE_COMPATIBILITY mode. Use Dialog#open(DialogCallback) instead.
    Returns:
    
    a string describing the absolute path of the first selected file, or null if the dialog was cancelled or an error occurred
    
    Throws:
    
    SWTException -
    
    ERROR_WIDGET_DISPOSED - if the dialog has been disposed
