The class
static-layout
is a layout that allows its children to be positioned anywhere within itself.
When a
static-layout
lays out its children, it positions them at the
x
and
y
specified as hints (using
:x
and
:y
), and sizes them to their minimum size (which can be specified using
:visible-min-width
and
:visible-max-width
).
If
fit-size-to-children
is true, the
static-layout
is made sufficiently large to accomodate all of its children, and grows if necessary when a child is added. This is the default behavior. Otherwise the static layout has a minimum size of one pixel by one pixel which is not affected by the size of its children. If you need the sizing capabilities, then use the class simple-layout which surrounds a single child, and adopts the size constraints of that child.
Here is an example of a static layout placing simple panes at arbitrary positions inside itself.
