Adding buttons to a slide in a Captivate project adds interactivity, and the multiple types of buttons available give you several ways to style those interactions.
New buttons like this one always start as a Text Button, consisting of a bit of text in a box. You can switch to another button type to have some more ways to customize its appearance.
Image buttons can use some built-in styles, or images that you supply yourself.
Select an image button.
Select an image style from the gallery.
OR
Click the Change button.
The file browser opens for you to select an image. You can select a single image to use as the button's regular appearance, but you can also use a set of images that will automatically be added as hover-over and down states, if they're named right.
Select an image.
Click Open.
The button changes to the selected image. That image is also added to the gallery, so that it's easier to use again elsewhere in your project.
One last thing to look at with buttons is the different button states. These states represent how a button looks normally, when the mouse cursor is hovering over it, and while clicked.
Select a button.
Click the Properties tab.
Click the State View button.
The Object State panel appears on the left, showing the different states of the button:
Normal state: How the button will look most of the time, when it's not being interacted with.
RollOver state: How the button will appear while the mouse cursor is hovering over it, but not clicking.
Down state: How the button will look while being clicked by the mouse.
Click a button state.
Edit a button state's formatting and add new elements.
