Thanks, it's finally working:
I modified the file IGraphicsCocoa.mm
In initWithIGraphics: (IGraphicsMac*) pGraphics added:
Code:
[self registerForDraggedTypes:[NSArray arrayWithObjects: NSFilenamesPboardType, nil]];
then
Code:
- (NSDragOperation)draggingEntered:(id <NSDraggingInfo>) sender {
NSPasteboard *pboard = [sender draggingPasteboard];
return (([pboard.types containsObject:NSFilenamesPboardType]) ? NSDragOperationLink : NSDragOperationNone);
}
- (BOOL)performDragOperation:(id <NSDraggingInfo>) sender {
NSPasteboard *pboard = [sender draggingPasteboard];
if ( [[pboard types] containsObject:NSFilenamesPboardType] ) {
NSPoint pt = [self convertPoint:[sender draggingLocation] fromView:nil];
for (NSString *path in [pboard propertyListForType:NSFilenamesPboardType]) {
const char* tmp=[path UTF8String];
if (mGraphics) {
mGraphics->OnMouseDragDrop(pt.x, mGraphics->Height() - pt.y, (char*)tmp);
break;
}
}
}
return YES;
}
Two questions:
How can I limit dragging on two types of files: wav and aif
This code also works on new versions of macOS, from Sierra above?
