GObject
org.gnu.gtk.TextMark
public class TextMark
extends GObject
TextView
overview which gives an
overview of all the objects and data types related to the text widget and how
they work together.
A 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 TextBuffer.getIter(TextMark)
. 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.
Marks optionally have names; these can be convenient to avoid passing the
TextMark object around.

public TextBuffer getBuffer()
Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.
Gets the buffer this mark is located inside, or NULL if the mark is deleted.
- Returns:
- The buffer/
public boolean getDeleted()
Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.
Returns TRUE if the mark has been removed from its buffer withTextBuffer.deleteMark(TextMark)
. Marks can't be used once deleted.
- Returns:
- True if deleted
public boolean getLeftGravity()
Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.
Determines whether the mark has left gravity.
- Returns:
- TRUE if the mark has left gravity, FALSE otherwise
public String getName()
Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.
Returns the mark name; returns NULL for anonymous marks.
- Returns:
- The name of the mark
public static Type getType()
Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.
Retrieve the runtime type used by the GLib library.
public boolean getVisibility()
Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.
Returns TRUE if the mark is visible (ie a cursor is displayed for it)
- Returns:
- true if it is visible
public void setVisibility(boolean setting)
Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.
Sets the visibility of mark; the insertion point is normally visible, ie 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.
- Parameters:
setting
- Visibility of mark
