In this lesson, we are going to see how we can construct rollovers that will display images when we put our mouse over the specific area. We are going to be using the Chapter 7_b file that we built earlier in this chapter. If you don't have it open, please open it now and then go to slide number 1, which is the Home slide. Let's begin by inserting a rollover area. Under Insert go to Standard Objects and choose Rollover Image. I want to choose the file called carnations in baskets.
This is in your Images folder in the Project folder in Chapter 7 Exercise Files folder. Again, choose carnations in baskets and then choose Open. This file is quite large. So let's fit it to the Stage and then we'll reduce it in size. Click and drag in the upper right-hand corner and set it to fill this entire over area here. Great. This is the image that's going to display when our mouse goes over this blue box, which is the rollover area.
We need to move the rollover area now, so that it's sitting on the displays button. The rollover area is underneath the picture. So we will slide the picture to the right a little bit. This will expose the rollover area. We can select it and then we can move it over here by displays. Make it to be a little bit smaller, so it's not touching the store or the gifts button. And then I would like to resize it to fit the button that it covers. If I right-click on the rollover area, you'll see also Auto-adjust Rollover Area.
Select it now. this will make the rollover area exactly fit the button that's underneath it. You can use this auto-fit to be able to stack buttons in rollover areas and images in rollover areas and other types of objects with rollover areas. Now we have got our rollover area in position and we have our content that we will display. Let's slide this back so that it fits appropriately on our stage. And I want to make one other adjustment to the rollover area itself.
You can see that it has a blue outline and I would like to change that to have no outline. Select it once again and under Fill and Stroke, change the Width to zero. Having made that change, let's preview our work. We don't see anything until we move our mouse over the displays button. Then the flowers will appear. When I move my mouse off they will disappear.
Let's repeat the process for store and gifts. With nothing selected we will insert another rollover image. Pick the file called flower storefront 02 and then Open. Again, we will fit it to the stage, so I will select it and Fit to the Stage. Slide it off to the side, so that we can get at the rollover area and put that on top of store.
Once again, we will Auto- adjust and set the outline to zero. Let's shrink this is a little bit. There we go. And the last one that we will build is for gifts. We will pick baskets and merchandise. And once again, we will have to Fit to Stage and reduce it in size.
Slide it off to the side, grab the rollover area and put that on top of gifts, and adjust it to fit. Set this back again so that it's fills the space and once again we will change the stroke to zero. These three images we can align, so if we select all of them, right-click, under Align we can align their centers and also align their middles. This is great.
Let's preview and see how this works. Once again, nothing happens until we mouse over store, displays, and gifts. There is our store, there is our display, and there are some gifts. Now that we have got our rollover areas built, let's save this file as Chapter 7_c.
Rollovers are an easy way for you to add interactivity to your presentations that you build in Captivate. Use them to provide additional imagery or information for the people who are viewing your presentations.
