NiceGrid

Description of NiceGrid /author Priyatna/

NiceGrid is a Delphi component that aimed to be a standard string grid replacement. It is written from scratch, not descended from TStringGrid. The main reason why I write this component is to have a grid component that nice and smooth. Here's some feature of NiceGrid:

• Headers can be merged and or multilined.
• Smooth scrolling, not aligned to top left cell coordinate.
• All aspect of grid colors can be customized: header light color, header dark color, header color, grid color, text color, etc.; resulting a real nice looking grid.
• Alternate row color.
• Can be customized at design time.
• Each column can have its own horizontal and vertical alignment, color, and font.
• Each column can be hidden.
• Can be auto fit to width.
• Can be auto calculate column width.
• BeginUpdate and EndUpdate method for bulk cells access.

Since it is a new component, there are several main differences between NiceGrid and TStringGrid:

• Headers are excluded from cells, unlike TStringGrid that treats fixed rows as regular cells (Row 0, for example), Cells[0,0] in NiceGrid will access the top left editable cells, not fixed cell.

• The only way to access the data is using Cells property or using direct array referencing style: NiceGrid1[0,0]. There are not (yet) Cols, or Rows property.

• FixedRows -> Header, FixedCols -> Gutter.
