As it was stated in U++ docs, I may post additional argument to a function creating a toolbar:

	void OnUpdateGraphToolbar(GraphProjectUI &ui, bool newTabSelected)
	{
		ui.toolsGraphs.Clear();
		ui.toolsGraphs.Set(callback1(this, &GraphProject::SetToolsGraphs, &ui));
	}

	void SetToolsGraphs(Bar &b, GraphProjectUI *ui)
	{
		gecs.InstallToDropCtrl(ui->colls);
		b.Add(ui->colls, 100, ui->colls.GetStdSize().cy);
		b.Add(!ui->colls.GetData().IsNull(), GraphEditorImg::graph_add, callback(this, &GraphProject::Dummy));
		b.ToolGapRight();
		b.Separator();
		b.Add(false, GraphEditorImg::graph_remove, callback(this, &GraphProject::Dummy));
	}

But when I try to post two additional arguments:

	void OnUpdateGraphToolbar(GraphProjectUI &ui, bool newTabSelected)
	{
		ui.toolsGraphs.Clear();
		ui.toolsGraphs.Set(callback2(this, &GraphProject::SetToolsGraphs, &ui, newTabSelected));
	}

	void SetToolsGraphs(Bar &b, GraphProjectUI *ui, bool newTabSelected)
	{
		if (newTabSelected)
			gecs.InstallToDropCtrl(ui->colls);
		b.Add(ui->colls, 100, ui->colls.GetStdSize().cy);
		b.Add(!ui->colls.GetData().IsNull(), GraphEditorImg::graph_add, callback(this, &GraphProject::Dummy));
		b.ToolGapRight();
		b.Separator();
		b.Add(false, GraphEditorImg::graph_remove, callback(this, &GraphProject::Dummy));
	}

-- it fails to compile!

I may of course work around this, but IMO it is a U++ bug.
