layout row column logic

• each panel maintains a cursor

• cursors are initialized to row 1, column 1

• increment cursor column logic:

  • increment cursor column
  • if parent columns specified (not "auto")
  • if column cursor extends past number of columns
    • if row != same
    • increment cursor row
    • cursor column = 1

• row can be #, span, next===undefined, same or full

• column can be #, span, next===undefined or full

• keys:

  • gc grid-column
  • gr grid-row
  • gtc grid-template-column
  • gtr grid-template-row

cases

• row #, column #

  • gr = row #, gc = column #
  • cursor row = gr, cursor column = gc
  • increment cursor column

• row #, column span

  • gr = row #, gc = column-span-start/column-span-end
  • cursor row = gr, cursor column = column-span-end
  • increment cursor column

• row #, column next

  • gr = row #, gc = cursor column
  • cursor row = gr
  • increment cursor column

• row #, column full

  • gr = row #, gc = 1/-1
  • cursor row = gr + 1, cursor column = 1

• row span, column #

  • gr = row-span-start/row-span-end, gc = column #
  • cursor row = row-span-end, cursor column = gc
  • increment cursor column

• row span, column span

  • gr = row-span-start/row-span-end, gc = column-span-start/column-span-end
  • cursor row = row-span-end, cursor column = column-span-end
  • increment cursor column

• row span, column next

  • gr = row-span-start/row-span-end, gc = cursor column
  • cursor row = row-span-end
  • increment cursor column

• row span, column full

  • gr = row-span-start/row-span-end, gc = 1/-1
  • cursor row = row-span-end + 1, cursor column = 1

• row next, column #

  • gr = cursor row, gc = column #
  • increment cursor row, cursor column = 1

• row next, column span

  • gr = cursor row, gc = column-span-start/column-span-next
  • increment cursor row, cursor column = 1

• row next, column next

  • gr = cursor row, gc = cursor column
  • increment cursor row, cursor column = 1

• row next, column full

  • gr = cursor row, gc = 1/-1
  • increment cursor row, cursor column = 1

• row same, column #

  • gr = cursor row, gc = column #
  • cursor column = gc
  • increment cursor column(row=same)

• row same, column span

  • gr = cursor row, gc = column-span-start/column-span-next
  • cursor column = col-span-end
  • increment cursor column(row=same)

• row same, column next

  • gr = cursor row, gc = cursor column
  • increment cursor column(row=same)

• row same, column full

  • disallowed, row filled

• row full, column #

  • gr = 1/-1, gc = column #
  • cursor column = gc
  • increment cursor column(row=same)

• row full, column span

  • gr = 1/-1, gc = column-span-start/column-span-end
  • cursor column = column-span-end
  • increment cursor column(row=same)

• row full, column next

  • gr = 1/-1, gc = cursor column
  • increment cursor column(row=same)

• row full, column full

  • disallowed, would take up full parent panel
