Most fully, inactive tabs look like this:
|
|
L C R
|
|
/ --- \
|
|
| === |
|
|
|
|
Where L,C, and R denote the tile positions. Of course, we don't want to draw all of the rounding for all the tabs.
|
|
|
|
We want the left-most tab to look like this:
|
|
|
|
L C
|
|
/ --
|
|
| ==
|
|
|
|
"Middle" tabs look like this:
|
|
|
|
L C
|
|
| --
|
|
| ==
|
|
|
|
And the right most tab looks like this:
|
|
|
|
L C R
|
|
| -- \
|
|
| == |
|
|
|
|
So we have to vary the number of columns, and for everything but left-most tab, the L tab gets the special separator
|
|
tile.
