Implementing a vertical icon tool bar in Java Swing

Question

I'm trying to implement a vertical tool bar on my paint app with window builder [swing] , but I can't put more than one tool items on it because they keep staying side to side to each other.

And I can't find a place to change the tool item appearance to a icon of my choice.

Here is the part of the code I have tried

ToolBar toolBar = new ToolBar(shell, SWT.FLAT | SWT.RIGHT);
    toolBar.setBounds(0, 0, 43, 319);
    formToolkit.adapt(toolBar);
    formToolkit.paintBordersFor(toolBar);

    ToolItem tltmTool = new ToolItem(toolBar, SWT.NONE);
    tltmTool.setText("tool 1");

    ToolItem tltmTool_1 = new ToolItem(toolBar, SWT.NONE);
    tltmTool_1.setText("tool 2");

if anyone have a tip I would appreciate it

Answer 1

After a little struggle here is the solution i acomplished.

ToolBar toolBar = new ToolBar(shell, SWT.FLAT | SWT.RIGHT | SWT.VERTICAL);
    toolBar.setBackground(SWTResourceManager.getColor(SWT.COLOR_WIDGET_LIGHT_SHADOW));
    toolBar.setBounds(3, 0, 43, 319);
    formToolkit.adapt(toolBar);
    formToolkit.paintBordersFor(toolBar);

    ToolItem tltmTool = new ToolItem(toolBar, SWT.NONE);
    tltmTool.setImage(SWTResourceManager.getImage("C:\\Users\\Magwire\\Pictures\\Icons\\1491427712_mouse-pointer.png"));
    tltmTool.setToolTipText("Ferramenta Seta");

    ToolItem tltmTool_2 = new ToolItem(toolBar, SWT.NONE);
    tltmTool_2.setImage(SWTResourceManager.getImage("C:\\Users\\Magwire\\Pictures\\Icons\\1491429896_draw-08.png"));
    tltmTool_2.setToolTipText("Ferramenta Deletar");

it was like @HovercraftFullOfEels and @ostrichofevil said... it is easier to set things the way i want without the GUI, and in the end i used it just to give-me the sample code...

Thanks everyone that helped !
