Hi,

{custom_view_nib_file}

Internal Panel Options:
  -I, --internal-panel aPanel <plist> <nib_file> Show internal panel.
        aPanel: open, save, color [:= Open File, Save File, Color  
Picker Dialog]
           open - Parameters: windowTitle, startDir, button1,  
message, allowMultipleSelection
                              fileType [string or array],  
canChooseDir, file
           save - Parameters: windowTitle, startDir, button1,  
message, allowOtherFileTypes
                              fileType [string or array], label, file
           color - Parameters: windowTitle, message, color [string of  
#RRGGBB notation]
                        -- a custom view is not supported
        nib_file: contains a customm view with control elements which  
will be shown
                         at the bottom of the open/save dialog

Returned plist:
	open/save:
	<dict>
		<key>buttonClick</key>
		<integer>1</integer>
		<key>result</key>
		<dict>
			<key>URL</key>
			<string>file://localhost/usr/share/doc/bash/article.pdf</string>
			<key>absoluteFileName</key>
			<string>/usr/share/doc/bash/article.pdf</string>
			<key>directory</key>
			<string>/usr/share/doc/bash</string>
			<key>pathExtension</key>
			<string>pdf</string>
		</dict>
	</dict>

	open with parameter allowMultipleSelection:
	<dict>
		<key>buttonClick</key>
		<integer>1</integer>
		<key>result</key>
		<dict>
			<key>absoluteFileNames</key>
			<array>
				<string>/Users/Bibiko/DialogPlugin.zip</string>
				<string>/Users/Bibiko/fehlerrate.pdf</string>
			</array>
		</dict>
	</dict>

	open/save with a custom view with a checkbox - selection key = 'Check':
	<dict>
		<key>buttonClick</key>
		<integer>1</integer>
		<key>result</key>
		<dict>
			<key>URL</key>
			<string>file://localhost/usr/share/doc/bash/article.pdf</string>
			<key>absoluteFileName</key>
			<string>/usr/share/doc/bash/article.pdf</string>
			<key>directory</key>
			<string>/usr/share/doc/bash</string>
			<key>pathExtension</key>
			<string>pdf</string>
			<key>Check</key>
			<integer>1</integer>
		</dict>
	</dict>

	
	color:
	<dict>
		<key>color</key>
		<string>#00C960</string>
		<key>result</key>
		<dict>
			<key>returnArgument</key>
			<string>#00C960</string>
		</dict>
	</dict>
	
	

Notes:

The parameters allowMultipleSelection, canChooseDir, and  
allowOtherFileTypes are boolean in such a way that if one write them  
in a plist they'll be set to YES automatically regardingless what  
value the key has!
E.g. {canChooseDir;} == {canChooseDir="1";} == {canChooseDir=0;} === YES
That also means that these parameters are set to NO as default.

The default of the parameter 'startDir' is, if not set, $HOME. You  
can set - startDir="nil"; - to set it automatically to the last path  
which was chosen.

The parameter 'fileType' can be a single string like fileType="txt";  
or an array fileType=("txt","tab"); .

The Color Picker is realized by a nib file which is stored in  
$TM_SUPPORT_PATH/nibs. If one invoke it a dialog with a ColorWell  
appears and the ColorPanel pops up automatically. If one press OK/ 
Cancel the ColorPanel will also closed.

If one want to preset a file in open/save you can use the parameters  
'startDir' and 'file'. 'file' is only the file name without the path!

My question for now is whether I should change something before I  
post the code to Alan?

PS I found my fault with the value transformer. Now it works  
perfectly ;)
