6 178 Day 6 each time. To place multiple components on the form, press and hold the Shift key when selecting the component from the Component Palette. After you select the component, you can release the Shift key. The component’s button on the Component Palette will appear pressed and will be highlighted with a blue border. Click on the form to place the first component. Notice that the button stays pressed in the Component Palette. You can click as many times as you like; a new component will be placed each time you click the form. To stop placing components, click the selector button on the Component Palette (the arrow button). The component button pops up to indicate that you are done placing components. Seeing is believing, so follow these steps: 1. Create a new project. 2. Press and hold the Shift key on the keyboard and click on the Label component button in the Component Palette. 3. Click three times on the form, moving the cursor each time to indicate where you want the new component placed. 4. Click the arrow button on the Component Palette to end the process and return to form design mode. NOTE TIP It’s fastest to place all components of a particular type on your form at one time using this technique. Components can always be rearranged and resized at a later time. When placing multiple copies of a particular component, it’s easy to forget to click the arrow button when you’re done. If you accidentally place more components than you intended, you can simply delete any extras. Placing and Centering a Component on the Form C++Builder provides a shortcut method of placing a component on a form. Simply doubleclick the component’s button in the Component Palette, and the component will be placed on the form. The component will be centered on the form both horizontally and vertically. Components placed with this method can be moved to another location on the form just like components placed in the usual method.
NOTE The C++Builder IDE Explored: Projects and Forms Each time you double-click a button on the Component Palette, a component is placed on the center of the form in the component’s default size. If you repeatedly double-click the component button, multiple copies of the component will be placed on the form. Each component will be placed in the center of the form and will be stacked on top of the previous one. It will appear as if you have a single component, so you may not realize that you have several components occupying the same space. If you accidentally place multiple components, just click on the extra components and delete them from the form. The Component Palette Speed Menu When you place the mouse cursor over the Component Palette and click the right mouse button, you will see a speed menu specific to the Component Palette. (See Figure 6.5.) Figure 6.5. The Component Palette speed menu. The Show Hints item toggles the tool tips on and off for the component buttons. Unless you really dislike tool tips, this should be left on. The Hide item on the speed menu hides the Component Palette. In order to show the Component Palette again, you will have to choose View | Component Palette from the main menu. The Help item on the speed menu brings up C++Builder help with the Component Palette page displayed. The Properties item brings up the Palette page of the Environment Options dialog box, where you can customize the Component Palette. Here you can add and remove pages of the Component Palette. You can also add, remove, or rearrange the order of components on the individual pages. I’ll discuss this in more detail on Day 10, when we look at setting the environment options. Navigating the Component Palette As mentioned earlier, you can drag the sizing bar, located between the toolbar and the Component Palette, to make the Component Palette occupy more or less room on the C++Builder main window. If the Component Palette is sized small enough so that it cannot display all its tabs, you will see scroll buttons in the upper-right corner of the Component 179 6
