Hello list, I´m new to gtk development and find myself in some need of advice. What I´d like to accomplish is the following:
I have a custom C++ class - which is not a widget - with 3 properties I´m interested in: name (Glib::ustring), date of creation (Glib::Date), and count of contained items (int). For all of them there´s a getter function implemented. That´s all pretty straightforward. What I want is to be able to represent a list of such custom class instances to the user in a Gtk::TreeView, where all 3 properties are in the same cell, probably in two lines. There won´t be any children elements to a top-level entry in the tree view. Here some ascii art for further clarification. __________________________________________________________________________________ | | | | column 0 | HERE THE VALUE OF CustomClassInst1.get_name() IN BIGGER FONT | | contains a | | | icon | Created on: MyCustomClassInst1.get_date() Items: get_count()| |_____________|__________________________________________________________________| | | | | column 0 | HERE THE VALUE OF CustomClassInst2.get_name() IN BIGGER FONT | | contains a | | | icon | Created on: MyCustomClassInst2.get_date() Items: get_count()| |_____________|__________________________________________________________________| and so on. I´d like to declare the second column in my TreeModel as Gtk::TreeModelColumn<MyCustomClass> m_column1. Further more at a later point I would need to be able to change the sorting of the TreeView from name to date or item count. So the question to the experts is: what do I need to implement - CellRenderer, TreeModel, or both? (None of the values in the view will be editable by hand, ever.) And next, how do I go about it? I´ve looked at the treemodelcustom example from the gtkmmm distribution but that´s really far off from what I need. If anyone knows of an application which does something similar, please just point me to the source; I´ll figure it out from there. Advice will be highly appreciated. Kind regards, T.Todorov _______________________________________________ gtkmm-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gtkmm-list
