TextView.addChildInWindow

void addChildInWindow(gtk.widget.Widget child, gtk.types.TextWindowType whichWindow, int xpos, int ypos)

Adds a child at fixed coordinates in one of the text widget's windows.

The window must have nonzero size (see [gtk.text_view.TextView.setBorderWindowSize]). Note that the child coordinates are given relative 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) it will move with the scrolling as needed.

Parameters

childa #GtkWidget
whichWindowwhich window the child should appear in
xposX position of child in window coordinates
yposY position of child in window coordinates
