236 Day 7 The Align Tops, Align Bottoms, and Align Right Edges options work just like the Align Left Edges option we used earlier. There’s not much point in going over all the possibilities that exist for their use. TIP The first component selected will be the anchor point when you’re using any of the edge-alignment options. Refer to Figure 7.4. Let’s say you had selected Button3 first and then used Shift+click to select the remaining buttons. When you chose Align Left Edges, Button3 would remain where it is and all other buttons would be lined up with Button3’s left edge because Button3 is the anchor component. The Align Horizontally Across Centers and Align Vertically Across Centers options can be used to center components relative to one another. This is best illustrated with shapes. Start with a new form (or delete the buttons from the form you have been working on). Now do the following: 1. Click on the Additional tab on the Component Palette and choose the Shape component. Click somewhere on the upper left of the form to add the shape. 2. Change the Shape property to stCircle. 3. Change the Width property to 150. 4. Double-click the Brush property and change the Color property of the Brush property to clBlack. 5. Place another Shape component on the form. 6. Change the second shape’s Shape property to stCircle as well. Now you have two circles of different sizes on the screen—a white circle and a black circle. 7. Click on the black circle. Hold the Shift key and click on the white circle. Both shapes are selected. 8. Choose View | Alignment Palette from the main menu, if necessary (it may already be displayed). Arrange the Alignment Palette so you can see the two shapes on the form. Observe the shapes as you perform the following two steps. 9. Click the Align Vertically Across Centers button on the Alignment Palette. The vertical centers are aligned. 10. Click the Align Horizontally Across Centers button on the Alignment Palette. The horizontal centers are aligned. Congratulations—you made a tire! Did you see the impact as you performed the last two steps? Notice that because you selected the black circle first, it did not move (it is the anchor component), but the white circle moved as you clicked the alignment buttons. You can use these alignment options to center any
Working with the Form Designer and the Menu Designer number of controls on one another. These two alignment options have no effect when used on a single control. Like the Component Palette, the Alignment Palette has a speed menu associated with it. Place the mouse cursor over the Alignment Palette and click the secondary mouse button. The speed menu is displayed. Table 7.2 lists the items on the Alignment Palette’s speed menu and explains their use. Table 7.2. The Alignment Palette’s speed menu items. Menu Item Description Stay on top Forces the Alignment Palette to always be on top. This is useful if you are frequently switching back and forth between the Form Designer and the Code Editor. Because the Alignment Palette is a small window, it’s easy to lose it. Show Hints Turns the hints (tool tips) for the Alignment Palette buttons on and off. Hide Hides the Alignment Palette. (You can also use the close box on the Alignment Palette to hide it.) In order to show the Alignment Palette again, you have to choose View | Alignment Palette from the main menu. Help Brings up C++Builder Help with the Alignment Palette page displayed. The Alignment dialog box performs the same actions as the Alignment Palette. To bring up the Alignment dialog box, choose Edit | Align from the main menu or Align from the Form Designer’s speed menu. Figure 7.14 shows the Alignment dialog box. Figure 7.14. The Alignment dialog box. In most cases, the Alignment Palette is easier to use, but you may certainly use the Alignment dialog box if you prefer. 237 7
