242 Day 7 6. Change the Name property of the Font property to Fixedsys. (Because this is a Notepad copycat, we’ll use the system font.) 7. Change the Align property to alClient. The memo expands to fill the client area between the speedbar and the status bar. Hey, this is starting to look like a real application! Before we go on, let’s do one more thing so you can see the value of the Align property. We need to make the main form a little larger. Grab the lower-right corner of the form with the mouse and drag the form to a larger size. If you want to be exact, you can change the form’s Height property to 375 and the Width property to 575. TIP The client area of our form is completely covered by components. This makes it impossible to select the form by clicking on it if you want to change the form’s properties. To make the form the active component in the Object Inspector, select any component on the form and then press the Esc key on the keyboard. You can also choose the form from the Component Selector combo box on the Object Inspector. Notice that all the controls automatically resize themselves to retain their relationship with the parent window—the form, in this case. That is one of the main advantages of the Align property. The form now looks like the one in Figure 7.16. Figure 7.16. The completed prototype. Run, Baby, Run You can now click the Run button to run the program. You can type text in the client area of the window, and you can press the speedbar buttons (although they don’t do anything at this point). Keep in mind that this is a prototype and is mostly for show right now. We’ll add more to the program by the end of the chapter.
Working with the Form Designer and the Menu Designer We better save the project because we’re going to use it later in the chapter. Choose File | Save All from the main menu. Save the main form’s source unit as SPMain and the project as Scratch. Setting the Tab Order NEW TERM NOTE The tab order refers to the order in which components will receive input focus when the user presses the Tab key on the keyboard. C++Builder forms automatically support component navigation using the Tab key. You can move forward from component to component using Tab and backward using Shift+Tab. There are two types of visual components. Windowed components are components that accept focus. Windowed components include the Edit, Memo, ListBox, ComboBox, and Button components, as well as many more. Non-windowed components are components that do not accept keyboard focus. Components such as Image, SpeedButton, Label, Shape, and many others are non-windowed components. The tab order applies only to windowed components. Non-windowed components are excluded from the tab order. The tab order is initially set based on the order the components were placed on the form when the form was designed. You can modify the tab order by changing the TabOrder property for each control in the Object Inspector. That method is tedious because you have to go to each control individually. An easier way is provided via the Edit Tab Order dialog box. (See Figure 7.17.) Figure 7.17. The Edit Tab Order dialog box. 243 7
