GdkCursorGetTextureCallback

typedef GdkTexture *(* GdkCursorGetTextureCallback) (GdkCursor *cursor, int cursor_size, double scale, int *width, int *height, int *hotspot_x, int *hotspot_y, gpointer data)

GdkCursorGetTextureCallback: @cursor: the GdkCursor @cursor_size: the nominal cursor size, in application pixels @scale: the device scale @width: (out): return location for the actual cursor width, in application pixels @height: (out): return location for the actual cursor height, in application pixels @hotspot_x: (out): return location for the hotspot X position, in application pixels @hotspot_y: (out): return location for the hotspot Y position, in application pixels @data: User data for the callback

The type of callback used by a dynamic GdkCursor to generate a texture for the cursor image at the given @cursor_size and @scale.

The actual cursor size in application pixels may be different from @cursor_size x @cursor_size, and will be returned in @width, @height. The returned texture should have a size that corresponds to the actual cursor size, in device pixels (i.e. application pixels, multiplied by @scale).

This function may fail and return NULL, in which case the fallback cursor will be used.

Returns: (nullable) (transfer full): the cursor image, or NULL if none could be produced.
