Method Details

onMoveCursor

boolean onMoveCursor(int step,
 int count,
 boolean extend,
 boolean modify)

Emitted when the user initiates a cursor movement.

This is a [keybinding signal](class.SignalAction.html).
Applications should not connect to it, but may emit it with
g_signal_emit_by_name() if they need to control the cursor
programmatically.

The default bindings for this signal come in two variants,
the variant with the Shift modifier extends the selection,
the variant without the Shift modifier does not.
There are too many key combinations to list them all here.

- <kbd>←</kbd>, <kbd>→</kbd>, <kbd>↑</kbd>, <kbd>↓</kbd>
move by individual children
- <kbd>Home</kbd>, <kbd>End</kbd> move to the ends of the box
- <kbd>PgUp</kbd>, <kbd>PgDn</kbd> move vertically by pages

Parameters:

step - the granularity fo the move, as a `GtkMovementStep`

count - the number of @step units to move

extend - whether to extend the selection

modify - whether to modify the selection

Returns:

%TRUE to stop other handlers from being invoked for the event. %FALSE to propagate the event further.
