Hi, I am trying to draw points of data using a custom PlotArea class that inherits Gtk::Layout and Cairo::Context. I have placed it inside a Gtk::ScrolledWindow so that I can scroll when the PlotArea's size (set with Gtk::Layout's set_size() ) is bigger than the visible area. This I have been able to do with no problems.
However, I also want to show tooltips when the mouse cursor is on top of a data point. I have been unable to achieve this because of the scroll capability as the rectangle coordinates used for a tooltip seem to be counted from the corner of the widget no matter which part of it is visible. Is there a way to determine the corner of the visible area when the Layout is inside a ScrolledWindow, for example, so that I could figure out where the tooltips are supposed to be? Or is there an another approach that I could use? I only need to be able to show different coloured points with tooltips and be able to zoom and scroll the area? Thanks beforehand, Tomi _______________________________________________ gtkmm-list mailing list gtkmm-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtkmm-list
