Hi,
trying to build a custom subclass of NSTextAttachment I thought it would be
fully supported in an NSTextView.
In a test project at app launch I insert an attachment:
[_textView setString:@"This is a test string\rThis is a test string\rThis
is a test string\rThis is a test string\rThis is a test string\rThis is a test
string\rThis is a test string\rThis is a test string\rThis is a test
string\rThis is a test string\r"];
TATextAttachment *att = [[TATextAttachment alloc] init];
NSAttributedString *as = [NSAttributedString
attributedStringWithAttachment:att];
[[_textView textStorage] appendAttributedString:as];
In the attachment I draw a custom cell. It all works so far, but when I select
a text that contains that custom attachment and drag the selection to another
location, only the text without the custom attachment cell icon is inserted at
the new location.
When dragging a text that contains a regular NSTextAttachment it gets dragged
and dropped as a file icon in the new location.
Why?
Alex
