## Description

This widget is based on the GtkFileChooser in the save mode. It proposes the user to choose a file to save to. In addition, it automatically build a list of filters, corresponding to the available export routines in V_Sim. By default, the filter is set on 'auto', which means that the filter method is selected with the file extension. The dialog also has a progress bar.

This widget is also a dialog, and should be used with `gtk_dialog_run()`. After the response GTK_RESPONSE_ACCEPT has been recieved, one can grep the selected filename with `dumpDialogGet_fileName()`. The dialog does not call the exporting routine by itself, the calling method should take care of that. When doing it, the filechoosing part should be made insensitive, using `dumpDialogStart()` and the progress bar should be updated accordingly (get it with `dumpDialogGet_progressBar()`).

The user interface propose also to change the size (see `dumpDialogGet_heightValue()` and `dumpDialogGet_widthValue()`) and if some options are associated to a file format, these options are displayed.

Retrieve interesting widget.

`dialog` : | a DumpDialog object.
Returns : | a pointer to the progress bar.

### dumpDialogGet_widthValue ()

    gint                dumpDialogGet_widthValue            (DumpDialog *dialog);

Retrieve request image size.

`dialog` : | a DumpDialog object.
Returns : | the width value.

    gint                dumpDialogGet_heightValue           (DumpDialog *dialog);

Retrieve request image size.

`dialog` : | a DumpDialog object.
Returns : | the height value.

### dumpDialogStart ()

    void                dumpDialogStart                     (DumpDialog *dialog);
