◆ SDL_ClipboardCleanupCallback
typedef void(* SDL_ClipboardCleanupCallback) (void *userdata) |
Callback function that will be called when the clipboard is cleared, or new data is set.
- Parameters
-
userdata | a pointer to provided user data. |
- Since
- This function is available since SDL 3.0.0.
- See also
- SDL_SetClipboardData
Definition at line 166 of file SDL_clipboard.h.
◆ SDL_ClipboardDataCallback
typedef const void *(* SDL_ClipboardDataCallback) (void *userdata, const char *mime_type, size_t *size) |
Callback function that will be called when data for the specified mime-type is requested by the OS.
The callback function is called with NULL as the mime_type when the clipboard is cleared or new data is set. The clipboard is automatically cleared in SDL_Quit().
- Parameters
-
userdata | a pointer to provided user data. |
mime_type | the requested mime-type. |
size | a pointer filled in with the length of the returned data. |
- Returns
- a pointer to the data for the provided mime-type. Returning NULL or setting length to 0 will cause no data to be sent to the "receiver". It is up to the receiver to handle this. Essentially returning no data is more or less undefined behavior and may cause breakage in receiving applications. The returned data will not be freed so it needs to be retained and dealt with internally.
- Since
- This function is available since SDL 3.0.0.

void * SDL_GetClipboardData |
( |
const char * |

Get the data from clipboard for a given mime type.
The size of text data does not include the terminator, but the text is guaranteed to be null terminated.
- Parameters
-
mime_type | the mime type to read from the clipboard. |
size | a pointer filled in with the length of the returned data. |
- Returns
- the retrieved data buffer or NULL on failure; call SDL_GetError() for more information. This should be freed with SDL_free() when it is no longer needed.

Retrieve the list of mime types available in the clipboard.
- Parameters
-
num_mime_types | a pointer filled with the number of mime types, may be NULL. |
- Returns
- a null terminated array of strings with mime types, or NULL on failure; call SDL_GetError() for more information. This should be freed with SDL_free() when it is no longer needed.

Get UTF-8 text from the clipboard.
This functions returns empty string if there was not enough memory left for a copy of the clipboard's content.
- Returns
- the clipboard text on success or an empty string on failure; call SDL_GetError() for more information. This should be freed with SDL_free() when it is no longer needed.

Get UTF-8 text from the primary selection.
This functions returns empty string if there was not enough memory left for a copy of the primary selection's content.
- Returns
- the primary selection text on success or an empty string on failure; call SDL_GetError() for more information. This should be freed with SDL_free() when it is no longer needed.

◆ SDL_SetClipboardData()
Offer clipboard data to the OS.
Tell the operating system that the application is offering clipboard data for each of the proivded mime-types. Once another application requests the data the callback function will be called allowing it to generate and respond with the data for the requested mime-type.
The size of text data does not include any terminator, and the text does not need to be null terminated (e.g. you can directly copy a portion of a document)
- Parameters
-
callback | a function pointer to the function that provides the clipboard data. |
cleanup | a function pointer to the function that cleans up the clipboard data. |
userdata | an opaque pointer that will be forwarded to the callbacks. |
mime_types | a list of mime-types that are being offered. |
num_mime_types | the number of mime-types in the mime_types list. |
- Returns
- true on success or false on failure; call SDL_GetError() for more information.

- This function is available since SDL 3.0.0.

- Returns
- true on success or false on failure; call SDL_GetError() for more information.
