View Full Version : TreeGrid text style

12 Dec 2011, 10:06 AM
Hi everybody.

Using a TreeGrid, how can i change the style of text (that appear near the tree icon) in the TreeGrid, only for some rows? I know it is possible to change the text style in the other columns of the associated grid implementing a GridCellRenderer interface and overriding the render method, but i don't find a similar solution with the class TreeGridCellRenderer.

You can use the WidgetTreeGridCellRenderer for the first column. Then you can still determine if you wan't the style of the text to be changed.

private final WidgetTreeGridCellRenderer<Folder> renderer = new WidgetTreeGridCellRenderer<Folder>() {

public Widget getWidget(Folder model, String property, ColumnData config, int rowIndex, int colIndex,
ListStore<Folder> store, Grid<Folder> grid) {

String style = model.get(property) == true ? "color: red" : "color:blue";

final StringBuilder html = new StringBuilder("<div style='" + style + "'>" + 10 + "</div>);
final Html l = new Html(html.toString());
return l;
