if I use performDragOperation from GLFW 3.3.4, it works…
{
const NSRect contentRect = [window->ns.view frame];
// NOTE: The returned location uses base 0,1 not 0,0
const NSPoint pos = [sender draggingLocation];
_glfwInputCursorPos(window, pos.x, contentRect.size.height - pos.y);
NSPasteboard* pasteboard = [sender draggingPasteboard];
NSDictionary* options = @{NSPasteboardURLReadingFileURLsOnlyKey:@YES};
NSArray* urls = [pasteboard readObjectsForClasses:@[[NSURL class]]
options:options];
const NSUInteger count = [urls count];
if (count)
{
char** paths = calloc(count, sizeof(char*));
for (NSUInteger i = 0; i < count; i++)
paths[i] = _glfw_strdup([urls[i] fileSystemRepresentation]);
_glfwInputDrop(window, (int) count, (const char**) paths);
for (NSUInteger i = 0; i < count; i++)
free(paths[i]);
free(paths);
}
return YES;
}
