get_iter_at_position

Retrieves the iterator pointing to the character at buffer coordinates x and y.

Buffer coordinates are coordinates for the entire buffer, not just the currently-displayed portion. If you have coordinates from an event, you have to convert those to buffer coordinates with [method@Gtk.TextView.window_to_buffer_coords].

Note that this is different from [method@Gtk.TextView.get_iter_at_location], which returns cursor locations, i.e. positions between characters.

Parameters:

this	a `GtkTextView`
iter	a `GtkTextIter`
trailing	if non-null, location to store an integer indicating where in the grapheme the user clicked. It will either be zero, or the number of characters in the grapheme. 0 represents the trailing edge of the grapheme.
x	x position, in buffer coordinates
y	y position, in buffer coordinates

Returns:

true if the position is over text
