Re: GtkD - how to list 0..100K strings

[mark via Digitalmars-d-learn]

I've now got it to work but it is unusable!

It can show small numbers of rows with no problem.
However, if it has to show 100s of rows it expands the tree 
vertically way beyond the bottom of the screen and is impossible 
to navigate.

However, if it has to show 1000s of rows it goes into an infinite 
loop producing endless error messages:

    (DebFind:6615): Gtk-WARNING **: 10:57:04.275: infinite 
surface size not supported

I suppose I was expecting scrollbars to appear, but maybe with 
Gtk you have do add them separately?

// Here's the view I'm now using
class View : TreeView {
    import gtk.CellRendererText: CellRendererText;
    import gtk.TreeViewColumn: TreeViewColumn;
    import qtrac.debfind.modelutil: NameAndDescription;
    import qtrac.debfind.viewdata: ViewData;

    ViewData viewData;
    TreeViewColumn nameColumn;
    TreeViewColumn descriptionColumn;

    this() {
        super();
        setActivateOnSingleClick(true);
        viewData = new ViewData;
        setModel(viewData);
        auto renderer = new CellRendererText;
        nameColumn = new TreeViewColumn("Name", renderer, "text", 
0);
        nameColumn.setResizable(true);
        appendColumn(nameColumn);
        renderer = new CellRendererText;
        descriptionColumn = new TreeViewColumn("Description", 
renderer,
                                               "text", 1);
        descriptionColumn.setResizable(true);
        appendColumn(descriptionColumn);
    }

    void clear() {
        viewData.clear;
    }

    void populate(NameAndDescription[] namesAndDescriptions) {
        viewData.populate(namesAndDescriptions);
    }
}

// Here's the ListStore I'm using:
class ViewData : ListStore {
    import qtrac.debfind.modelutil: NameAndDescription;

    this() {
        import gobject.c.types: GType;
        super([GType.STRING, GType.STRING]);
    }

    void populate(NameAndDescription[] namesAndDescriptions) {
        import gtk.TreeIter: TreeIter;

        clear;
        TreeIter iter;
        foreach (i, nameAndDescription; namesAndDescriptions) {
            append(iter);
            setValue(iter, 0, nameAndDescription.name);
            setValue(iter, 1,                  
nameAndDescription.description);
        }
    }
}

// I have the TreeView side-by-side with a TextView: here're 
snippets:
        Paned splitter;
        View debsView;
        TextView debTextView;
...
        splitter = new Paned(GtkOrientation.HORIZONTAL);
        splitter.setWideHandle(true);
        debsView = new View;
        debsView.setHexpand(true);
        debsView.setVexpand(true);
        debTextView = new TextView;
...
        auto grid = new Grid;
...
        splitter.pack1(debsView, false, true);
        splitter.pack2(debTextView, true, true);
        grid.attach(splitter, 0, 3, 6, 1);
