The component library provides abstract components you can use as the basis for customized components. The most important of these are grids and list boxes. The following topics describe how to create a small one month calendar from the basic grid component, TCustomGrid:

• Creating and registering the component
• Publishing inherited properties
• Changing initial values
• Resizing the cells
• Filling in the cells
• Navigating months and years
• Navigating days

In VCL applications, the resulting component is similar to the TCalendar component on the Samples category of the Tool palette. See Specifying the palette page.
