A flexible JavaScript drag-and-drop tile system

flowgrid's Issues

Redrawing cells will overwrite drawn state

If you are hovering over a cell, and then it is redrawn with, say, redrawCellAtIndex, it will be drawn in the default state, as if it was not being hovered.

Keyboard controls

You should be able to navigate FlowGrids using only the keyboard (this is useful for use in games, etc.).

Add event listener elements

There should be a way to add objects to grids that can respond to the different events—e.g. perform some action when they are clicked, or a cell is dropped on them, etc. This would allow for far more complex interactions—e.g. filtering a grid's content when different buttons are pressed, etc.

Delegate methods

These methods are currently missing:

• Rearranged / swapped cells (within the same grid)

Grid-dependent tile appearances

There are certain situations (inventories and the like) where it would be useful to allow a single cell to have different appearances (but remain the same object) when in different FlowGrids. It might be possible to make this work at the moment, but if not, it would be a useful feature to have.

Missing options

These options would be useful but are missing:

• Accepts cells from other grids

Data sources

Instead of simply manipulating the FlowGrid cells, one should be able to link a data source (as well as a way to interpret it), which is manipulated as the cells are dragged around, etc.

Add the ability to dynamically resize the grid

Allowing the user to have resizable windows containing FlowGrids, for instance.

Filtering and sorting

You should be able to apply filters to only display cells matching a predicate, as well as rearrange the order of cells (programatically, that is) without actually changing the underlying data order.

Multiple selection

When you click on a cell without dragging it, it should become selected. There should be an option to select multiple cells at once (shift-clicking), as well as dragging a selection rectangle to select lots of cells in one go.

Animate cell movement

When cells are being displaced and when they are dropped, there should be an option to animate their movement instead of instantly snapping into place.
