|
|
| Description |
- This is an interface for simple single-line text editing widgets. It is
implemented by Entry and SpinButton.
- TODO
- Find out if "insert-text" signal is useful and how to bind it. It is
tricky because it has an in-out parameter.

|
| Methods |
|
| editableSelectRegion :: EditableClass ed => ed -> Int -> Int -> IO () |
Select a span of text.
- A negative end position will make the selection extend to the
end of the buffer.
- Calling this function with start=1 and end=4 it will
mark "ask" in the string "Haskell". (FIXME: verify)
|
|
| editableGetSelectionBounds :: EditableClass ed => ed -> IO (Int, Int) |
Get the span of the current selection.
- The returned tuple is not ordered. The second index represents the
position of the cursor. The first index is the other end of the
selection. If both numbers are equal there is in fact no selection.
|
|
| editableInsertText :: EditableClass ed => ed -> String -> Int -> IO Int |
Insert new text at the specified position.
- If the position is invalid the text will be inserted at the end of the
buffer. The returned value reflects the actual insertion point.
|
|
| editableDeleteText :: EditableClass ed => ed -> Int -> Int -> IO () |
Delete a given range of text.
- If the end position is invalid, it is set to the lenght of the
buffer.
- start is restricted to 0..end.
|
|
| editableGetChars :: EditableClass ed => ed -> Int -> Int -> IO String |
Retrieve a range of characters.
- Set end to a negative value to reach the end of the buffer.
|
|
| editableCutClipboard :: EditableClass ed => ed -> IO () |
| Cut the selected characters to the Clipboard.
|
|
| editableCopyClipboard :: EditableClass ed => ed -> IO () |
| Copy the selected characters to the Clipboard.
|
|
| editablePasteClipboard :: EditableClass ed => ed -> IO () |
| Paste the selected characters to the
Clipboard.
|
|
| editableDeleteSelection :: EditableClass ed => ed -> IO () |
| Delete the current selection.
|
|
| editableSetEditable :: EditableClass ed => ed -> Bool -> IO () |
Make the widget insensitive.
- Called with False will make the text uneditable.
|
|
| editableGetEditable :: EditableClass ed => ed -> IO Bool |
| Retrieves whether the text is editable.
|
|
| editableSetPosition :: EditableClass ed => ed -> Int -> IO () |
| Set the cursor to a specific position.
|
|
| editableGetPosition :: EditableClass ed => ed -> IO Int |
| Get the current cursor position.
|
|
| Signals |
|
| onEditableChanged :: EditableClass ec => ec -> IO () -> IO (ConnectId ec) |
| Emitted when the settings of the Editable widget changes.
|
|
| afterEditableChanged :: EditableClass ec => ec -> IO () -> IO (ConnectId ec) |
|
| onDeleteText :: EditableClass ec => ec -> (Int -> Int -> IO ()) -> IO (ConnectId ec) |
| Emitted when a piece of text is deleted from the Editable widget.
|
|
| afterDeleteText :: EditableClass ec => ec -> (Int -> Int -> IO ()) -> IO (ConnectId ec) |
