gtkTextViewAddChildInWindow {RGtk2} | R Documentation |
Adds a child at fixed coordinates in one of the text widget's
windows. The window must have nonzero size (see
gtkTextViewSetBorderWindowSize
). Note that the child
coordinates are given relative to the GdkWindow
in question, and
that these coordinates have no sane relationship to scrolling. When
placing a child in
GTK_TEXT_WINDOW_WIDGET, scrolling is irrelevant, the child floats above all scrollable areas. But when placing a child in one of the scrollable windows (border windows or text window), you'll need to compute the child's correct position in buffer coordinates any time scrolling occurs or buffer changes occur, and then call
gtkTextViewMoveChild
to update the
child's position. Unfortunately there's no good way to detect that
scrolling has occurred, using the current API; a possible hack
would be to update all child positions when the scroll adjustments
change or the text buffer changes. See bug 64518 on
bugzilla.gnome.org for status of fixing this issue.
