Version

Flags

•

-Chdir

•

Enable the user to change directories. The default is 1. If disabled, the directory list box will not be shown.

-Create

•

Enable the user to specify a file that does not exist. If not enabled, and the user specifies a non-existent file, a dialog box will be shown informing the user of the error (This Dialog Box is configurable via the EDlg* switches, below).

default: 1

-ShowAll

•

Determines whether hidden files (.*) are displayed in the File and Directory Listboxes. The default is 0. The Show All Checkbox reflects the setting of this switch.

-DisableShowAll

•

Disables the ability of the user to change the status of the ShowAll flag. The default is 0 (the user is by default allowed to change the status).

-Grab

•

Enables the File Dialog to do an application Grab when displayed. The default is 1.

-Horiz

•

True sets the File List box to be to the right of the Directory List Box. If 0, the File List box will be below the Directory List box. The default is 1.

-SelDir

•

If True, enables selection of a directory rather than a file, and disables the actions of the File List Box. The default is 0.

Special

•

-FPat

•

Sets the default file selection pattern. The default is '*'. Only files matching this pattern will be displayed in the File List Box.

-Geometry

•

Sets the geometry of the File Dialog. Setting the size is a dangerous thing to do. If not configured, or set to '', the File Dialog will be centered.

-SelHook

•

SelHook is configured with a reference to a routine that will be called when a file is chosen. The file is called with a sole parameter of the full path and file name of the file chosen. If the Create flag is disabled (and the user is not allowed to specify new files), the file will be known to exist at the time that SelHook is called. Note that SelHook will also be called with directories if the SelDir Flag is enabled, and that the FileDialog box will still be displayed. The FileDialog box should not be destroyed from within the SelHook routine, although it may generally be configured.

SelHook routines return 0 to reject the selection and allow the user to reselect, and any other value to accept the selection. If a SelHook routine returns non-zero, the FileDialog will immediately be withdrawn, and the file will be returned to the caller.

There may be only one SelHook routine active at any time. Configuring the SelHook routine replaces any existing SelHook routine. Configuring the SelHook routine with 0 removes the SelHook routine. The default SelHook routine is undef.

Strings

•

-File The file selected, or the default file. The default is ''.

-Path The path of the selected file, or the initial path. The default is $ENV{'HOME'}.

Labels and Captions

•

-Title The Title of the dialog box. The default is 'Select File:'.

-DirLBCaption The Caption above the Directory List Box. The default is 'Directories'.

-FileLBCaption The Caption above the File List Box. The default is 'Files'.

-FileEntryLabel The label to the left of the File Entry. The Default is 'Filename:'.

-PathEntryLabel The label to the left of the Path Entry. The default is 'Pathname:'.

-FltEntryLabel The label to the left of the Filter entry. The default is 'Filter:'.

-ShowAllLabel The text of the Show All Checkbutton. The default is 'Show All'.

Button Text

•

-OKButtonLabel The text for the OK button. The default is 'OK'.

-RescanButtonLabel The text for the Rescan button. The default is 'Rescan'.

-CancelButtonLabel The text for the Cancel button. The default is 'Cancel'.

Error Dialog Switches

•

-EDlgTitle

•

The title of the Error Dialog Box. The default is 'File does not exist!'.

-EDlgText

•

The message of the Error Dialog Box. The variables $path, $file, and $filename (the full path and filename of the selected file) are available. The default is "You must specify an existing file.\n(\$filename not found)"
