It can be intimidating at first, but after a while you start to see what the designers were up to. All other files are files that C++Builder will re-create when you compile the program. For instance, you might want to compile the program just to see whether there are any errors. The Code Editor is displayed with the cursor placed in the event-handler function. Invokes C++Builder help with the toolbar page displayed. Console applications are useful in teaching situations and for quick test programs.
A modal form must be dismissed before the user can continue to use the application. Scroll down through the properties until you locate the Left property and then click on it. A little skeptical, are you? Choose File Include Unit Hdr from the main menu. You could also press F9 or choose Run Run from the main menu. The Include Unit dialog box.
Now you are prompted for the project name. Now, before you label me as a code-bloat proponent, let me say that I am as conscientious as the next guy when it comes to code bloat. This team brings hundreds of thousands of working hours in professional software development to the creation of this extensive work. By the way, this code snippet could be condensed a little. What happens next is one of the great things about visual programming.
Change the Caption property of the form to Bitmap Test Program. Events in Windows include a menu being activated, a button being clicked, a window being moved, a window needing repainting, a window being activated, and so forth. Now add three text labels to the box. C++Builder displays the Object Repository. From the main menu, choose File New.
As far as you are concerned, you are just programming in C++. Still, there are times when you need to create components at runtime, and C++Builder allows you to do that. Clicking this button will invoke the property editor for that particular control. These classes are used by many of the component classes to store strings. If you accidentally place more components than you intended, you can simply delete any extras. Choose the Standard tab on the Component Palette and click the Memo button. The compiler status dialog box.
It made perfect sense for the people at Borland to take an already-existing class library and adapt it for use in C++Builder. I am also a realist, and I understand that time-to-market is a driving force in the software industry today. The do-while loop ensures that the user presses a key between 1 and 3. A good framework implements object-oriented design and objectoriented programming to apply an object-oriented approach to writing Windows applications. The Build All option takes the longest to perform. Position the icon as desired. System Component Classes The System tab on the Component Palette contains a mixture of visual and nonvisual components.
The compile status dialog box showing warnings and errors. The default value is bsSizeable, which creates a window that can be sized. Components placed with this method can be moved to another location on the form just like components placed in the usual method. The calling form can then read ModalResult to see which button was clicked to close the form. It should come as no surprise that the Form Editor allows you to create forms.
You could use a panel to build a status bar, for example. You could use this event to perform any processing that your form needs to do just before it is shown. This class provides all the functionality that a basic component requires. You might have dialog box—looking windows, and you may have other windows that resemble traditional windows. Switch to the Code Editor press F12 and select the Main. They can also be very useful for small utility programs, servers such as Web servers or mail servers, and a whole host of other possibilities.
