onMoveCursor

fun onMoveCursor(connectFlags: <Error class: unknown class> = ConnectFlags(0u), handler: (step: MovementStep, <Error class: unknown class>, extendSelection: Boolean) -> Unit): <Error class: unknown class>(source)

Gets emitted when the user initiates a cursor movement.

The ::move-cursor signal is a class.SignalAction.html. If the cursor is not visible in @text_view, this signal causes the viewport to be moved instead.

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 it does not. There are too many key combinations to list them all here.

  • ←, →, ↑, ↓ move by individual characters/lines

  • Ctrl+←, etc. move by words/paragraphs

  • Home and End move to the ends of the buffer

  • PgUp and PgDn move vertically by pages

  • Ctrl+PgUp and Ctrl+PgDn move horizontally by pages

Parameters

connectFlags

a combination of ConnectFlags

handler

the Callback to connect. Params: step the granularity of the move, as a GtkMovementStep; count the number of @step units to move; extendSelection true if the move should extend the selection
