Monomer-Hagrid

A datagrid widget for the Monomer library.

Current Status

• Somewhat buggy and incomplete. Don't build your business on this.

Current Features

• Vertical and horizontal scrolling.
• Resizable columns.
• Column sorting, with a customizable sort key.
• Configurable column alignment (left or right).
• Custom widgets for each cell, to override the standard label.
• Custom width/height padding for each cell, configured per column.
• Scrolling to a particular row when sent a message.
• Custom footer widgets on the bottom of each column.
• Efficient implementation that only inflates visible widgets, scaling to at least 10000 rows.

Definite Future Goals

• Better documention.
• Better tests.
• Prettier appearance.

Possible Future Goals

• Explore providing an API where current sort/column widths/etc are stored in the parent model and updated by hagrid via a lens. This may remove some complexity around merging and the specification of initial sorts/column widths.
