Trait containing all TreeDragDest methods.

Provided Methods§

source

fn drag_data_received(&self, dest: &TreePath, value: &Value) -> bool

👎Deprecated: Since 4.10

Asks the TreeDragDest 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!

Deprecated since 4.10

Use list models instead

dest

row to drop in front of

value

data to drop

Returns

whether a new row was created before position @dest

source

fn row_drop_possible(&self, dest_path: &TreePath, value: &Value) -> bool

👎Deprecated: Since 4.10

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

Deprecated since 4.10

Use list models instead

dest_path

destination row

value

the data being dropped

Returns

true if a drop is possible before @dest_path
