GdkPaintablecompute_concrete_size
Declaration [src]
void
gdk_paintable_compute_concrete_size (
GdkPaintable* paintable,
double specified_width,
double specified_height,
double default_width,
double default_height,
double* concrete_width,
double* concrete_height
)
Description [src]
Compute a concrete size for the GdkPaintable
.
Applies the sizing algorithm outlined in the
CSS Image spec
to the given paintable
. See that link for more details.
It is not necessary to call this function when both specified_width
and specified_height
are known, but it is useful to call this
function in GtkWidget:measure implementations to compute the
other dimension when only one dimension is given.
Parameters
specified_width

Type:
double

double
The height
paintable
could be drawn into or 0.0 if unknown. default_width

Type:
double
The width
paintable
would be drawn into if no other constraints were given. default_height

paintable
would be drawn into if no other constraints were given. concrete_width

Type:
double*
Will be set to the concrete width computed.
The argument will be set by the function. concrete_height
