CHAPTER 3 CREATING AN APPLICATION S USER INTERFACE The PushButton Control As you saw in previous chapters, the PushButton control, shown in Figure 3-37, is used to display buttons that users can click to initiate specific actions. Figure 3-37. Examples of PushButton controls, as shown on Mac OS X The RadioButton Control The RadioButton control, which you can see in Figure 3-38, is used to present users with a choice between one or more values. RadioButton controls operate in groups, where only one RadioButton in the group can be selected at a time. In situations where you want to create distinct sets of RadioButton controls on the same window, you can use the GroupBox control to separate and organize the RadioButton controls. Figure 3-38. Examples of RadioButton controls, as shown on Windows The Rb3Dspace Control The Rb3Dspace control provides you with the capability to display animation in a predefined three-dimensional space. The RbScript Control The RbScript control provides you with the capability to let users submit REALbasic code, and then executes it from your compiled application. While this control does provide your application with functionality, it is invisible to the user. The Rectangle Control The Rectangle control, seen in Figure 3-39, provides the capability to draw rectangle and square shapes on windows. Rectangle drawings are, by default, 1 pixel thin and they are black with a white center. However, you can change line thickness, as well as line and fill colors.
