|
* @brief Variadic template to wrap an xcb request.
|
|
|
|
*
|
|
|
|
* This struct is part of the generic implementation to wrap xcb requests
|
|
|
|
* and fetching their reply. Each request is represented by two templated
|
|
|
|
* elements: WrapperData and Wrapper.
|
|
|
|
*
|
|
|
|
* The WrapperData defines the following types:
|
|
|
|
* @li reply_type of the xcb request
|
|
|
|
* @li cookie_type of the xcb request
|
|
|
|
* @li function pointer type for the xcb request
|
|
|
|
* @li function pointer type for the reply
|
|
|
|
* This uses variadic template arguments thus it can be used to specify any
|
|
|
|
* xcb request.
|
|
|
|
*
|
|
|
|
* As the WrapperData does not specify the actual function pointers one needs
|
|
|
|
* to derive another struct which specifies the function pointer requestFunc and
|
|
|
|
* the function pointer replyFunc as static constexpr of type reply_func and
|
|
|
|
* reply_type respectively. E.g. for the command xcb_get_geometry:
|
|
|
|
* @code
|
|
|
|
* struct GeometryData : public WrapperData< xcb_get_geometry_reply_t, xcb_get_geometry_cookie_t, xcb_drawable_t >
|
|
|
|
* {
|
|
|
|
* static constexpr request_func requestFunc = &xcb_get_geometry_unchecked;
|
|
|
|
* static constexpr reply_func replyFunc = &xcb_get_geometry_reply;
|
|
|
|
* };
|
|
|
|
* @endcode
|
|
|
|
*
|
|
|
|
* To simplify this definition the macro XCB_WRAPPER_DATA is provided.
|
|
|
|
* For the same xcb command this looks like this:
|
|
|
|
* @code
|
|
|
|
* XCB_WRAPPER_DATA(GeometryData, xcb_get_geometry, xcb_drawable_t)
|
|
|
|
* @endcode
|
|
|
|
*
|
|
|
|
* The derived WrapperData has to be passed as first template argument to Wrapper. The other
|
|
|
|
* template arguments of Wrapper are the same variadic template arguments as passed into
|
|
|
|
* WrapperData. This is ensured at compile time and will cause a compile error in case there
|
|
|
|
* is a mismatch of the variadic template arguments passed to WrapperData and Wrapper.
|
|
|
|
* Passing another type than a struct derived from WrapperData to Wrapper will result in a
|
|
|
|
* compile error. The following code snippets won't compile:
|
|
|
|
* @code
|
|
|
|
* XCB_WRAPPER_DATA(GeometryData, xcb_get_geometry, xcb_drawable_t)
|
|
|
|
* // fails with "static assertion failed: Argument miss-match between Wrapper and WrapperData"
|
|
|
|
* class IncorrectArguments : public Wrapper<GeometryData, uint8_t>
|
|
|
|
* {
|
|
|
|
* public:
|
|
|
|
* IncorrectArguments() = default;
|
|
|
|
* IncorrectArguments(xcb_window_t window) : Wrapper<GeometryData, uint8_t>(window) {}
|
|
|
|
* };
|
|
|
|
*
|
|
|
|
* // fails with "static assertion failed: Data template argument must be derived from WrapperData"
|
|
|
|
* class WrapperDataDirectly : public Wrapper<WrapperData<xcb_get_geometry_reply_t, xcb_get_geometry_request_t, xcb_drawable_t>, xcb_drawable_t>
|
|
|
|
* {
|
|
|
|
* public:
|
|
|
|
* WrapperDataDirectly() = default;
|
|
|
|
* WrapperDataDirectly(xcb_window_t window) : Wrapper<WrapperData<xcb_get_geometry_reply_t, xcb_get_geometry_request_t, xcb_drawable_t>, xcb_drawable_t>(window) {}
|
|
|
|
* };
|
|
|
|
*
|
|
|
|
* // fails with "static assertion failed: Data template argument must be derived from WrapperData"
|
|
|
|
* struct FakeWrapperData
|
|
|
|
* {
|
|
|
|
* typedef xcb_get_geometry_reply_t reply_type;
|
|
|
|
* typedef xcb_get_geometry_cookie_t cookie_type;
|
|
|
|
* typedef std::tuple<xcb_drawable_t> argument_types;
|
|
|
|
* typedef cookie_type (*request_func)(xcb_connection_t*, xcb_drawable_t);
|
|
|
|
* typedef reply_type *(*reply_func)(xcb_connection_t*, cookie_type, xcb_generic_error_t**);
|
|
|
|
* static constexpr std::size_t argumentCount = 1;
|
|
|
|
* static constexpr request_func requestFunc = &xcb_get_geometry_unchecked;
|
|
|
|
* static constexpr reply_func replyFunc = &xcb_get_geometry_reply;
|
|
|
|
* };
|
|
|
|
* class NotDerivedFromWrapperData : public Wrapper<FakeWrapperData, xcb_drawable_t>
|
|
|
|
* {
|
|
|
|
* public:
|
|
|
|
* NotDerivedFromWrapperData() = default;
|
|
|
|
* NotDerivedFromWrapperData(xcb_window_t window) : Wrapper<FakeWrapperData, xcb_drawable_t>(window) {}
|
|
|
|
* };
|
|
|
|
* @endcode
|
|
|
|
*
|
|
|
|
* The Wrapper provides an easy to use RAII API which calls the WrapperData's requestFunc in
|
|
|
|
* the ctor and fetches the reply the first time it is used. In addition the dtor takes care
|
|
|
|
* of freeing the reply if it got fetched, otherwise it discards the reply. The Wrapper can
|
|
|
|
* be used as if it were the reply_type directly.
|
|
|
|
*
|
|
|
|
* There are several command wrappers defined which either subclass Wrapper to add methods to
|
|
|
|
* simplify the usage of the result_type or use a typedef. To add a new typedef one can use the
|
|
|
|
* macro XCB_WRAPPER which creates the WrapperData struct as XCB_WRAPPER_DATA does and the
|
|
|
|
* typedef. E.g:
|
|
|
|
* @code
|
|
|
|
* XCB_WRAPPER(Geometry, xcb_get_geometry, xcb_drawable_t)
|
|
|
|
* @endcode
|
|
|
|
*
|
|
|
|
* creates a typedef Geometry and the struct GeometryData.
|
|
|
|
*
|
|
|
|
* Overall this allows to simplify the Xcb usage. For example consider the
|
|
|
|
* following xcb code snippet:
|
|
|
|
* @code
|
|
|
|
* xcb_window_t w; // some window
|
|
|
|
* xcb_connection_t *c = connection();
|
|
|
|
* const xcb_get_geometry_cookie_t cookie = xcb_get_geometry_unchecked(c, w);
|
|
|
|
* // do other stuff
|
|
|
|
* xcb_get_geometry_reply_t *reply = xcb_get_geometry_reply(c, cookie, nullptr);
|
|
|
|
* if (reply) {
|
|
|
|
* reply->x; // do something with the geometry
|
|
|
|
* }
|
|
|
|
* free(reply);
|
|
|
|
* @endcode
|
|
|
|
*
|
|
|
|
* With the help of the Wrapper class this can be simplified to:
|
|
|
|
* @code
|
|
|
|
* xcb_window_t w; // some window
|
|
|
|
* Xcb::Geometry geo(w);
|
|
|
|
* if (!geo.isNull()) {
|
|
|
|
* geo->x; // do something with the geometry
|
|
|
|
* }
|
|

Use nullptr everywhere
Summary:
Because KWin is a very old project, we use three kinds of null pointer
literals: 0, NULL, and nullptr. Since C++11, it's recommended to use
nullptr keyword.
This change converts all usages of 0 and NULL literal to nullptr. Even
though it breaks git history, we need to do it in order to have consistent
code as well to ease code reviews (it's very tempting for some people to
add unrelated changes to their patches, e.g. converting NULL to nullptr).
Test Plan: Compiles.

Use nullptr everywhere
Summary:
Because KWin is a very old project, we use three kinds of null pointer
literals: 0, NULL, and nullptr. Since C++11, it's recommended to use
nullptr keyword.
This change converts all usages of 0 and NULL literal to nullptr. Even
though it breaks git history, we need to do it in order to have consistent
code as well to ease code reviews (it's very tempting for some people to
add unrelated changes to their patches, e.g. converting NULL to nullptr).
Test Plan: Compiles.

Use nullptr everywhere
Summary:
Because KWin is a very old project, we use three kinds of null pointer
literals: 0, NULL, and nullptr. Since C++11, it's recommended to use
nullptr keyword.
This change converts all usages of 0 and NULL literal to nullptr. Even
though it breaks git history, we need to do it in order to have consistent
code as well to ease code reviews (it's very tempting for some people to
add unrelated changes to their patches, e.g. converting NULL to nullptr).
Test Plan: Compiles.

Use nullptr everywhere
Summary:
Because KWin is a very old project, we use three kinds of null pointer
literals: 0, NULL, and nullptr. Since C++11, it's recommended to use
nullptr keyword.
This change converts all usages of 0 and NULL literal to nullptr. Even
though it breaks git history, we need to do it in order to have consistent
code as well to ease code reviews (it's very tempting for some people to
add unrelated changes to their patches, e.g. converting NULL to nullptr).
Test Plan: Compiles.
