qt - Tool Palette like in MS Paint -

I'm trying to create a tool palette (?) In QT Designer, such as left in MS Paint or Adobe Photoshop Side, with different mouse click and selection tool)

How do I do this? Is it using Toolbar?

Thanks

• If I need to run in windows
• You can not use the toolbar, just use simple tool-buttons that were added to grid-layout frame (or widget)
• and Qt example (in the Qt SDK installation Included) that gives you very useful clues on Qt programming
