is_trigger

Description:

public abstract bool is_trigger (View view, TextIter location, ModifierType state, uint keyval)

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 [const@Gdk.KEY_Return] or [const@Gdk.KEY_KP_Enter ] and state does not have gdk_shift_mask 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.

Parameters:

this	a Indenter
view	a View
location	the location where `ch` is to be inserted
state	modifier state for the insertion
keyval	the keyval pressed such as [const@Gdk.KEY_Return]

Returns:

true if indentation should be automatically triggered; otherwise false and no indentation will be performed.
