| Description |
A TreeSelection is a data type belonging to a TreeModel. As the name
suggests it holds the current selection which can even be a multiple
choice.
TODO
- treeSelectionGetSelected allows to retreive the associated TreeModel
object. We currently do not use this feature so it could be added
if needed.

choice TreeSelection.
|
|
| type TreeSelectionForeachCB = TreeIter -> IO () |

| Deselect a specific item by TreePath.
|
|
| treeSelectionPathIsSelected :: TreeSelectionClass ts => ts -> TreePath -> IO Bool |
| Returns True if the row at the given path is currently selected.
|
|
| treeSelectionSelectIter :: TreeSelectionClass ts => ts -> TreeIter -> IO () |
| Select a specific item by TreeIter.
|
|
| treeSelectionUnselectIter :: TreeSelectionClass ts => ts -> TreeIter -> IO () |
| Deselect a specific item by TreeIter.
|
|
| treeSelectionIterIsSelected :: TreeSelectionClass ts => ts -> TreeIter -> IO Bool |
| Returns True if the row at the given iter is currently selected.
|
|
| treeSelectionSelectAll :: TreeSelectionClass ts => ts -> IO () |
| Select everything.
|
|
| treeSelectionUnselectAll :: TreeSelectionClass ts => ts -> IO () |
| Deselect everything.
|
|
| treeSelectionSelectRange :: TreeSelectionClass ts => ts -> TreePath -> TreePath -> IO () |
| Select a range specified by two
TreePaths.
|
|
| onSelectionChanged :: TreeSelectionClass ts => ts -> IO () -> IO (ConnectId ts) |
| Emitted each time the user changes the selection.
