Next: Block Layout Conflicts, Previous: Alignment modifiers, Up: Block Layout [Contents]
There are two more attributes governing alignment. By default a block
is just as big as needed to contain its contained blocks. However, we can specify
an explicit size larger than this; it may have a very large label that makes it bigger
than its content; or its sides may be aligned so that it ends up being larger.
In this case the content.x
and content.y
attributes govern,
how the contained blocks are placed inside. They can take the following values:
left/top
, center/middle
, right/bottom
or justify
.
If you specify justify
the blocks that are laid out in relation to their
previous or next block will not necessarily "stick" to that previous or next block.
Additional space
may be added to have a justified layout inside the parent. It may sound complicated,
but in most practical cases it just works.
![]() | ![]() |
Inside a shape the content is placed into the area specified by the
T
command (used for labels in signalling charts). The whole shape will be
sized to be able to contain its contained blocks. On the figure below,
we define a simple triangular shape with fill (the part after S 0;
)
on the area, where content can go (the box designated at the last line)
![]() | ![]() |
Note that apart from sizing containers appropriately Msc-generator makes no attempt to avoid overlaps. Blocks go where you specify them and if they overlap they are simply drawn like that.
