TreeGrid setFixedFieldWidths behaviour change on 4.0p

[markok]

Hi,

Horizontal scrollbar with setFixedFieldWidths(true) set treegrid behaves differently in 4.0p branch compared to 3.1. Reproducible with the following:

    public Record gr(int i, Integer parent) {
        Record r = new ListGridRecord();
        r.setAttribute("id", "primarykey" + i);
        r.setAttribute("text", "node " + i);
        if(parent != null)
            r.setAttribute("parent", "primarykey" + parent);
        return r;
    }

    public void onModuleLoad() {
        SC.showConsole();

        viewport = new VLayout();
        viewport.setWidth100();
        viewport.setHeight100();
        viewport.setMembersMargin(20);

        final DataSource ds = new DataSource();
        DataSourceTextField pk = new DataSourceTextField("id");
        pk.setPrimaryKey(true);
        DataSourceTextField text = new DataSourceTextField("text");
        DataSourceTextField parent = new DataSourceTextField("parent");
        parent.setForeignKey("id");
        ds.setFields(pk, text, parent);
        ds.setClientOnly(true);
        ds.setTestData(gr(1, null), gr(2, 1), gr(3, 1), gr(4, 3), gr(5, 4), gr(6, 5), gr(7, 6), gr(8, 7));

        final TreeGrid g = new TreeGrid();
        g.setWidth(100);
        g.setHeight(200);
        g.setWrapCells(false);
        g.setFixedFieldWidths(false);
        g.setDataSource(ds);
        g.setAutoFetchData(true);
        TreeGridField f1 = new TreeGridField("text");
        g.setFields(f1);
        viewport.addMember(g);

        viewport.draw();
    }

When run with 3.1 (SmartClient Version: v8.3p_2013-02-16/LGPL Development Only (built 2013-02-16)) and opening up nodes until the content overflows from the right border a horizontal scrollbar appears correctly.

When run with 4.0p (SmartClient Version: v9.0p_2013-10-22/LGPL Development Only (built 2013-10-22)) the scroll bar does not appear and the content of the cell is cut up.

Tested with GWT 2.5.1 and latest Chrome 30.0.1599.101.

Thanks for the notification. We've made a change to address this issue (will be present in the next nightly build dated Oct 26 or above).
Also worth noting: The fixedFieldWidths:false setting is somewhat incompatible with headers as the headers don't automatically expand to match the body field widths. This has long been the case.
If you're showing a header, you may want to experiment with autoFitFieldWidths:true instead

Seems to be fixed now. Thanks for the hint about the header - we currently have no header in the tree but might have one some day.

Thanks!
