Indenter

Required methods

fn is_trigger<P: IsA<View>>(
    &self,
    view: &P,
    location: &TextIter,
    state: ModifierType,
    keyval: u32
) -> bool

This function is used to determine if a key pressed should cause the indenter to automatically indent.

The default implementation of this virtual method will check to see if keyval is GDK_KEY_Return or GDK_KEY_KP_Enter and state does not have gdk::ModifierType::ShiftMask set. This is to allow the user to avoid indentation when Shift+Return is pressed. Other indenters may want to copy this behavior to provide a consistent experience to users.

Feature: v5_0
