Bug Description

Binary package hint: tipptrainer

If I type a text in a lesson the text won't automatically scroll down. The cursor of the current position to type moves out of the visible area. I have to scroll manually. This happens for the y axis. The same happens for the x axis if I increase the font size so that lessons don't fit in the window horizontally.

Some more data: whenever ShowPosition(diffPos) in TtOutputControl::highlightChar in outputcontrol.cpp is called, a GTK assertion is fired:

(tipptrainer:19176): Gtk-CRITICAL **: gtk_text_view_scroll_to_mark: assertion `get_buffer (text_view) == gtk_text_mark_get_buffer (mark)' failed

and the position of the top pane moves to the top of the content instead of moving so that the highlighted line is visible. This makes the program completely unusable.

This may also be a problem in the wxTextCtrl implementation in libwxgtk2.6-0, which TtOutputControl inherits from.

Since the error message is from a function that is never directly called by tipptrainer, but only from some low-level wx code, this might actually be a wxGTK bug, especially since a tipptrainer package compiled from virtually unchanged sources used to work one or two years ago.
