class Gtk::TextMark

A Gtk::TextMark is like a bookmark in a text buffer; it preserves a position in the text. You can convert the mark to an iterator using Gtk::TextBuffer#iter_at_mark. Unlike iterators, marks remain valid across buffer mutations, because their behavior is defined when text is inserted or deleted. When text containing a mark is deleted, the mark remains in the position originally occupied by the deleted text. When text is inserted at a mark, a mark with left gravity will be moved to the beginning of the newly-inserted text, and a mark with right gravity will be moved to the end. "left" and "right" here refer to logical direction (left is the toward the start of the buffer); in some languages such as Hebrew the logically-leftmost text is not actually on the left when displayed.

Marks optionally have names; these can be convenient to avoid passing the Gtk::TextMark object around.

Marks are typically created using the Gtk::TextBuffer#create_mark.

Gtk::TextMark.new

• Returns: self: FIXME

buffer

Gets the Gtk::TextBuffer this mark is located inside, or nil if the mark is deleted.

• Returns: Gtk::TextBuffer

deleted?

Returns true if the mark has been removed from its buffer with Gtk::TextBuffer#delete_mark. Marks can't be used once deleted.

• Returns: true or false

left_gravity?

Determines whether the mark has left gravity.

• Returns: true if the mark has left gravity, false otherwise

name

Returns the mark name; returns nil for anonymous marks.

• Returns: mark name or nil

visible?

Returns true if the mark is visible (i.e. a cursor is displayed for it)

• Returns: true or false

visible=(setting)

Sets the visibility of mark; the insertion point is normally visible, i.e. you can see it as a vertical bar. Also, the text widget uses a visible mark to indicate where a drop will occur when dragging-and-dropping text. Most other marks are not visible. Marks are not visible by default.

• setting: visibility of mark (true or false)
• Returns: setting

set_visible(setting)

Same as Gtk::TextMark#visible=.

• setting: visibility of mark (true or false)
• Returns: Gtk::TextMark
