List of all members.

Public Member Functions
	ExportFileDialog (LPCTSTR lpszFilter=NULL)
	Contructs an export file dialog.
virtual void	AppendExtension (wxString *pFilename)
	Given a filename, this function will attach the appropriate file extension according to the chosen filter to it. Based on the function SaveFileDialog::AppendExtension but needs to append the selected filer name rather than an explicit .art.
virtual void	AddExtension (wxString *pFilename, BOOL Replace=FALSE, BOOL AskAboutReplace=FALSE, UINT32 Selection=0)
	Given a filename, this function will attach the appropriate file extension according to the chosen filter to it. Based on the function SaveFileDialog::AppendExtension but needs to append the selected filer name rather than an explicit .art.
void	ExportABitmap (BOOL bExportABitmap, KernelBitmap *pBitmap=0)
Protected Member Functions
virtual BOOL	ExplorerInitDialog (wxWindow *hDlg)
	Should be called when the explorer style dialog boxes need setting up. We can take this opportunity to add in any extra controls that we require.
virtual BOOL	HandleOptions ()
	Implements the options button installed for WEBSTER This opens the GIF Animation properties tabs dialog with the Browser PReview tab selected.
Protected Attributes
BOOL	m_bExportABitmap
KernelBitmap *	m_pBitmapToExport
Private Member Functions
BOOL	OnInitDialog (wxInitDialogEvent &event)
	Make the drop-down filter box bigger than usual.
void	DoDataExchange (CDataExchange *pDX)
	Handles data exchange messages for the export file dialog.
BOOL	OnFileNameOK ()
	So we can do our own 'that file already exists' check, as the standard one used Y/N and that is officially forbidden (despite the fact that 99.999% of Windows programs use it). Its an MFC overridable.
virtual void	OnTypeChange ()
	Should be called when the user has selected a new file type from the "Files of type" combo box. We might need to do things like fix the file extension for the currently selected save/export filter. Only called back if OFN_EXPLORER is set and you can only do this on Windows 95 otherwise a dialog is not popped up.
virtual void	OnLBSelChangedNotify (UINT32 nIDBox, UINT32 iCurSel, UINT32 nCode)
	Should be called when the user has selected a new file type from the "Files of type" combo box. We might need to do things like fix the file extension for the currently selected save/export filter. This should be called on all OS's, so we must disable it in Windows 95. This turns out not to be the case as it does not seem to get called on Windows 95, probably due to the ExportFileDialog::OnTypeChange() override. It is called on initing the dialog box but shouldn't cause a problem. Filenames of the sort *.gif are automatically fixed by the OS. As soon as you type a real name in though, they are no longer fixed!
virtual BOOL	IsValidFilename ()
	Check to see if the file name is OK.
BOOL	SetStateOnFilterChange ()
	Implements the options button installed for WEBSTER Finds out whether to grey the Options button and/or the Auto-preview checkbox.
afx_msg void	OnAutoPreview ()
	Should be called when the user has selected a new file type from the "Files of type" combo box. We might need to do things like fix the file extension for the currently selected save/export filter. Only called back if OFN_EXPLORER is set and you can only do this on Windows 95 otherwise a dialog is not popped up.
