If your application uses a file selection dialog box, it contains the following components:  

• A directory text component showing the current directory path. The user can edit the directory text component and press Return or Enter to change the current directory.

• For applications that allow saving to different formats, an option button allowing users to specify the format when saving a file.

• A file name text component for displaying and editing a file name. This component is optional when the file selection box is used to choose an existing file or directory.

• A group of push buttons, including a command button, and Update, Cancel, and Help buttons. The command button is typically labeled Open or Save, but if there is another label that better describes the resulting action (such as Include), that label should be used. Activating the command button carries out the corresponding action and dismisses the file selection box.

Recommended

Your application allows the user to select a file by scrolling through the list of file names and selecting the desired file or by entering the file name directly into the file selection text component. Selecting a file from the list causes that file name to appear in the file selection text area. 

This method of selecting a file needs to be consistent across applications. 

Required 

_ 

_ 

_ 

7-16: 

Your application makes use of the selection when one of the following occurs: 

• The user activates the command push button while an appropriate item is selected in the contents list.

hm: 

If the user has opened the application without supplying a file name argument, the Open dialog box should use the user's home directory as the default directory.  

An exception to this rule might be made if a clearly more useful directory can be identified; for example, the icon editor might default to HomeDirectory/.dt/icons. For Applications that allow editing, never default to a directory in which the user does not have read and write permission, such as /usr/dt/bin.

Required

Optional 

_ 

_ 

_ 

hp: 

When using the file selection dialog box in a Save As capacity, add a file name extension if the application supports file typing by extension, and make this extension visible in the file name field. Do not highlight the extension to create a "delete pending type-in" mode, but allow users to modify the extension or delete it explicitly. 

Optional 

_

hq: 

The file selection dialog box should come up in a directory that makes sense for the task. For example, when saving a new file from an editor, the file selection box should come up in the user's home directory. If the user navigates to some other directory within the file selection box, the application should remember that directory the next time it is brought up.

If a text component supports replace mode, insert toggles between insert mode and replace mode.  

By default, the component starts in insert mode, where the location cursor is between two characters. In insert mode, typing a character inserts the character at the position of the location cursor.  

In replace mode, the location cursor is on a character. Typing a character replaces the current character with that newly entered character and moves the location cursor to the next character, selecting it.  

These rules ensure the uniform operation of a text component with a replace mode.
