360 Day 10 The Project Explorer shows all of your project’s source units, forms, and components in a tree view. Nodes can be contracted or expanded to reveal more details. Each component is listed under its parent. For example, notice the SpeedBar node in Figure 10.4. In this project, the SpeedBar node is a Panel component that contains several speed buttons. The speed buttons are displayed underneath the panel to show that the panel is the parent of the speed buttons. The Project Explorer is a hierarchical window. At the top of the Project Explorer you have the project file; under the project file you have the project’s source units. Immediately under the project source file is the form file for that unit. Under the form file you have all the components that are direct children of the form. If a component on the form has children, they are listed under their parent, and so on. Figure 10.5 shows how the Project Explorer would look if the component and unit names were replaced with descriptive text. Figure 10.5. The Project Explorer hierarchy. When you click on an item in the Project Explorer, the status bar at the bottom of the Project Explorer window shows information about the item selected. If the item is a source file or form file, the status bar displays the full path and filename of the file. If the item is a component, the status bar displays the class name of the component. For example, if you click a speed button component, the Project Explorer status bar will display TSpeedButton. Project Explorer Commands You can do more than just view your objects in the Project Explorer. The Project Explorer has a speed menu that allows you to delete, rename, edit, or select an item. Not all speed menu items are available at all times, however. If you have selected a unit’s source file, for example, the Rename speed menu item is disabled because you cannot rename a source file from the Project Explorer. Let’s look at the Project Explorer commands individually. Select The Select menu item selects the current object and displays the object in the Object Inspector. The effect is the same as if you had selected the object in the Form Designer. If you place the Object Inspector and Project Explorer side by side, you can quickly go through all the objects in your project and view their properties. This command is available only if you have selected a form or a control.
Figure 10.6. The Project Explorer speed menu. NOTE More on Projects Just highlighting (selecting) the control in the Project Explorer tree is not the same as selecting it using the Select command. If you want the component to be displayed in the Object Inspector, you must first select the component in the Project Explorer tree and then choose Select from the speed menu. Edit The Edit speed menu item allows you to edit the object selected. If the object is a source file, choosing the Edit menu item will result in the Code Editor being displayed with the selected file loaded. If the object selected in the Project Explorer window is a form, the Form Designer comes to the top with the selected form displayed. If the object selected is a component on a form, the Form Designer is displayed, and the object is selected in the Form Designer as if you had clicked it with the mouse. In the case of forms and components, the Object Inspector changes to show the object selected. Rename The Rename menu item allows you to change the Name property of a form or a control from the Project Explorer. To change the name of a component, for example, first select the component in the Project Explorer window and then choose Rename from the speed menu. You can then type a new name for the component. As when changing the Name property in the Object Inspector, the change is immediately reflected throughout your program’s source code. 361 10
