dragDataReceived

treeDragDestDragDataReceived

Arguments

:: (HasCallStack, MonadIO m, IsTreeDragDest a)

=> a

dragDest: a GtkTreeDragDest

-> TreePath

dest: row to drop in front of

-> GValue

value: data to drop

-> m Bool

Returns: whether a new row was created before position dest

Deprecated: (Since version 4.10)Use list models instead

Asks the GtkTreeDragDest to insert a row before the path dest, deriving the contents of the row from value. If dest is outside the tree so that inserting before it is impossible, False will be returned. Also, False may be returned if the new row is not created for some model-specific reason. Should robustly handle a dest no longer found in the model!

rowDropPossible

treeDragDestRowDropPossible

Arguments

:: (HasCallStack, MonadIO m, IsTreeDragDest a)

=> a

dragDest: a GtkTreeDragDest

-> TreePath

destPath: destination row

-> GValue

value: the data being dropped

-> m Bool

Returns: True if a drop is possible before destPath

Deprecated: (Since version 4.10)Use list models instead

Determines whether a drop is possible before the given destPath, at the same depth as destPath. i.e., can we drop the data in value at that location. destPath does not have to exist; the return value will almost certainly be False if the parent of destPath doesn’t exist, though.
