[Gtk2hs-users] how to paste in a textbuffer

[John O'D. <jt...@dc...>]

Hi,

In gtk2hs (0.10.0, with ghc 6.10.3), I'm trying to make a Paste menu 
item work; i.e. trying to make it paste the clipboard into a text 
buffer.  (You can do cut, copy, paste by right clicking in the text, and 
then selecting the operation from the popup menu, but I'm trying to make 
an edit menu Paste entry do the same.)  Thus I just want the menu 
Edit:Paste to behave the same as right click: Paste.

The textBufferPasteClipboard appears to be suitable:

textBufferPasteClipboard
:: TextBufferClass self
=> self
-> Clipboard    clipboard - the GtkClipboard to paste from
-> TextIter    overrideLocation - location to insert pasted text
-> Bool    defaultEditable - whether the buffer is editable by default
-> IO ()

I would have expected the third (location) argument to be of type Maybe 
TextIter, so you could say Nothing to get the default location (the 
mouse cursor), and Just iter to override it.  But the type is TextIter, 
so it seems to be necessary to construct an Iter pointing to the default 
location, which should then override the default location in order to 
give the default location.  (Sounds a bit strange!)

Two questions:
   1.  Is there a way to do a paste simply, without the bother of making 
a TextIter?  The other operations with the edit menu are 1-liners.
  2.  How can you get a TextIter to point to where the mouse cursor is?

Thanks!
