| Dreamweaver dialog boxes are created using HTML forms stored in the Dreamweaver4/Configuration/C ommands directory. You can modify these HTML files to alter the appearance of Dreamweaver's dialog boxes permanently. Alterations to these dialog boxes are reflected across all Dreamweaver sites. Table 20-1 lists the files used to implement many of Dreamweaver's menu options. JavaScript within the HTML file, and in external .js files, controls the dialog boxes' functionality. You can edit these files to change the appearance and behavior of Dreamweaver's dialog boxes and menu commands. Most of these files are stored in the Dreamweaver4/Configuration/C ommands directory. Files whose paths begin with Shared are located in the Dreamweaver4/Configuration/Shared directory and are used by multiple dialog boxes. Table 20-1.

Figure 20-4. The Rollover.htm file  Notice that the options in this form match those used in the Insert Rollover Image dialog box shown in Figure 20-5. Figure 20-5. The Insert Rollover Image dialog box  Open the Rollover.htm file in Dreamweaver to see the HTML code used to implement the dialog box and the JavaScript used to manipulate the contents of this form ( Rollover.htm can be found in the Dreamweaver 4/Configuration/Command s folder). Figure 20-6 shows a modified version of the dialog box created by adding the following HTML code to the Rollover.htm file. As always, you should make a backup copy of your original files before making any changes. <p><i><b> Do not place any rollover images in documents intended for 3.0 and earlier browsers. </b></i></p> You must save the file and restart Dreamweaver before the changes will be reflected in the dialog box, as seen in Figure 20-6. Figure 20-6. Modified Insert Rollover Image dialog box  You can modify any dialog box to add functionality, remove functionality, or add helpful information as we did in the Insert Rollover Image dialog box.  | To make customization available to other users, copy the revised files manually to each computer's Dreamweaver4/ Configuration/Commands folder. | | 20.2.1 The Extensions.txt File The Extensions.txt file in the Dreamweaver4/ Configuration folder controls the pop-up list of file types available in the Open file dialog box (accessed via File Open). The first line of the Extensions.txt file determines the file types shown by default. Each line of the file contains a comma-separated list of file extensions (in capital letters ) followed by a colon and a description. For example, you can add this line to the Extensions.txt file to create a new category called Image Files: JPG,JPE,JPEG,GIF,PNG:Image Files Note that the All Documents category shows a more limited range of extensions than the All Files (*.*) category. Remember to back up the Extensions.txt file before making changes, and restart Dreamweaver to put the changes into effect. As you can see, Dreamweaver's interface is extremely flexible and extensible. In Chapter 22, we'll cover some behaviors used to extend Dreamweaver. Carried to its logical extreme, you can build an entirely new application on top of the Dreamweaver platform, as was done in the case of Dreamweaver UltraDev. The next chapter covers Dreamweaver's integration with server-side languages. |
