Browser Support & 508

Some versions of Netscape Navigator cannot display certain visual nuances of the standard tabstrip control.

This graphic is explained in the accompanying text.

Figure 1: Example of the standard tabstrip

This graphic is explained in the accompanying text.

Figure 2: Example of the tabstrip in Netscape Navigator 4

This tabstrip is much less sophisticated visually than the standard tabstrip (figure 1) - the tabs and the tab card have no border, there is a space between the tabs, and the height of the active tab is the same as the height of the inactive tabs.

This graphic is explained in the accompanying text.

Figure 3: Example of the tabstrip in Netscape Navigator 6.1

This tabstrip is different from the standard tabstrip (figure 1) in that there is a space between the tabs. Additionally, the active tab is the same height as the inactive tabs.

This graphic is explained in the accompanying text.

Figure 4: Example of the tabstrip in Netscape Navigator 6.2

This tabstrip is different from the standard tabstrip (figure 1) in that the tabs are all the same height.

Tabstrip Items

Tabstrip items cannot be stored on the Web client. The application has to manage tabstrip items. Therefore, changing the tabs always generates the event tabSelectionChange. It is recommended to at least declare the method so that no exception will be thrown if the application is opened in a Netscape Navigator 4 Web client.

Editability in Style Editor

In the Style Editor, it is possible to change all the background and border colors, as well as the padding and all the text attributes. Here is a list of the styles you can influence:
