It was a small program that wrote “hello, world” on the screen. In this section, we shall write a similar program for Small Windows. In regular C++, the execution of the application starts with the main function. In Small Windows, however, main is hidden in the framework and has been replaced by MainWindow, whose task is to define the application name and create the main window object. The following argumentList parameter corresponds to argc and argv in main. The commandShow parameter forwards the system's request regarding the window's appearance: Hello, Small World!
The Draw method has a second parameter indicating the draw mode, which can be Paint or Print. The Paint method indicates that the OnDraw method is called by the OnPaint method in the Window class and that the painting is performed in the window's client area. The Print method indicates that the OnDraw method is called by the OnPrint method and that the painting is sent to a printer. Draw(graphics); } } The RedRadio, GreenRadio, and BlueRadio methods are called before the menu items are shown, and the items will be marked with a radio button if they return true.
Instead, we use logical units that stay the same, regardless of the physical resolution of the screen. We can choose from the following three coordinate systems: LogicalWithScroll: A logical unit is one hundredth of a millimeter, with the current scroll bar settings taken into account. The drawing program and word processor use this system. LogicalWithoutScroll: A logical unit is one hundredth of a millimeter also in this case, but the current scroll bar settings are ignored. The spreadsheet program uses this system.
