Type Mappings#
The types used for properties in .slint
design markup each translate to specific types in C++.
The follow table summarizes the entire mapping:

The unit are physical pixels. |

At run-time, logical lengths are automatically translated to physical pixels using the device pixel ratio. |

At run-time, durations are always represented as signed 64-bit integers with millisecond precision. |

The order of the data member are in the same as in the slint declaration |
Structures#
The Slint compiler generates a class
with all data members in
lexicographic order for any user-defined, exported struct
in the .slint
code.
For example, this struct
in a .slint
file
export struct MyStruct {
foo: int,
bar: string,
}
will generate the following type in C++:
class MyStruct {
public:
int foo;
slint::SharedString bar;
};
