Description

Grid tabular list is a uniform grid that supports cell-by-cell navigation.

demo-01 demo-02 demo-03

Because this list is designed to show arbitrary numbers of columns, horizontal scrolling is supported through cell-by-cell navigation.

Grid tabular list tries to show the current column in the center. If it can't show the current column in the center, it shows the first column in the left corner or the last column in the right corner.

It should be fast enough to handle a large spreadsheet. It is also suitable for an interface to a database table.

GridTabularList
Fields list :: GenericList n Seq e The underlying primitive list that comes from brick widths :: Seq ColWidth currentColumn :: Index Manipulating this field directly is unsafe. Use column navigation functions to manipulate this. If you still want to manipulate this directly, create a function that manipulates it, and test the function properly.

Move to the next page of columns.

GridRenderers are needed because if row header doesn't exist, width calculation is affected.

Event handlers

handleGridListEvent Source #

Arguments

:: Ord n
=> GridRenderers n e	Renderers
-> Event
-> EventM n (GridTabularList n e) ()

Handle events for grid tabular list with navigation keys.

It adds the following keyboard shortcuts to handleListEvent.

Move to the left by one column (Left arrow key)
Move to the right by one column (Right arrow key)
Go to the first column (Ctrl+Home)
Go to the last column (Ctrl+End)
Move to the previous page of columns (Ctrl+PageUp)
Move to the next page of columns (Ctrl+PageDown)

GridRenderers are needed because if row header doesn't exist, width calculation is affected.

handleGridListEventVi Source #

Arguments

:: Ord n
=> GridRenderers n e	Renderers
-> Event
-> EventM n (GridTabularList n e) ()

Handle events for grid tabular list with vim keys.

It adds the following keyboard shortcuts to handleListEventVi.

Move to the left by one column (h)
Move to the right by one column (l)
Go to the first column (H)
Go to the last column (L)
Move to the previous page of columns (Alt+h)
Move to the next page of columns (Alt+l)

GridRenderers are needed because if row header doesn't exist, width calculation is affected.
