# 5.3. Previewing

## 5.3.1. Internal Previewing

Screem provides an in program preview so you can check your pages as you go along without having to launch an exernal program.

Currently the preview window is using GtkXmHtml, which is aimed at HTML 3.2 rather than HTML 4.0 and it also has quite a few problems. The use of this will change in the future, hopefully when Gtkhtml stabilises that can be used, and also when Mozilla is ready then that will hopefully be embeded via bonobo - the Gnome OLE style object embeding mechanism.

When you want to preview a page you are working on then simply click on the preview tab and you page will be shown. There is no need to save the page first as there is with the external browsers.

| One of the main problems with the GtkXmHtml widget is forms. If you are editing a page with any forms in then do not you use the built in preview. It also doesn't support things like java or javascript.

## 5.3.2. External Previewing

Should you wish to view a page in an external browser there are 4 options open to you:

- View in the default Gnome browser (usually set to netscape)

- View in user definable browser 1

- View in user definable browser 2

- View in user definable browser 3

Default Gnome browser

To do this you simply click on the icon, and the page will be loaded. You should save your page prior to clicking on the icon or you will not see the latest changes.

User definable browsers

When you first run Screem these will not be configured, so when you click on them a dialog will appear enabling you to set an icon to use in the toolbar, the pathname of the program to execute, and if they should use the url of the site you are editing for previewing the page. Once they have been configured they are used the same way as the default browser. If you should want to change the settings then you can simply right click on the icon and the settings dialog will appear again. The user definable browsers appear (by default) on the next toolbar along from the default browser.
