dwFillAttribute

dwFillAttribute is a variable or field name used in software development to represent the attributes of a fill operation. The prefix dw is commonly used in Windows programming to denote a DWORD, a 32-bit unsigned integer, and the name FillAttribute indicates that the value encodes how something should be filled during rendering, printing, or export.

Because there is no universal standard for dwFillAttribute, its precise meaning is specific to the API or library in which it appears. In many code bases the field is implemented as a bitmask or small enumeration, with different bits or ranges representing options such as fill style (solid, gradient, hatch), color information, opacity, or a selected fill pattern.

Example: in a hypothetical graphics API, a structure may include a member DWORD dwFillAttribute; If bit 0 indicates a solid fill and bits 1–3 select a fill pattern, a value of 0x00000001 would request a solid fill while 0x0000000A could select a particular pattern. The exact interpretation is defined by the API documentation.

In practice, developers should rely on the specific documentation for the API or library that defines dwFillAttribute, since naming conventions alone do not convey the full semantics.
