    I've put the whole code in the first time and it's the best I can do as I am new to Qt. I'm sure that when it is finished it will be a very useful widget for many people and also a good lesson of toolbars and layouts usage.

    here's the way to manage buttons manually, without layout, but it also doesn't work fine
    Qt Code: 
    1. void PaletteToolbar::arrangeButtons()
    2. {
    3. 	if (buttonList.size()!=0)
    4. 	{
    5. 		arranging = true;
    6. 		foreach(PaletteToolbarButton* button, buttonList)
    7. 		{
    8. 			button->hide();
    9. 		}
    10. 		expandButton->hide();
    11. 		int cellWidth = buttonList.first()->minimumWidth()+2;
    12. 		int cellHeight = buttonList.first()->minimumHeight()+2;
    13. 		int maxWidth = cellWidth, maxHeight = cellHeight;
    14. 		bool vert = orientation()==Qt::Vertical;
    15. 		switch(static_cast<QMainWindow*>(parentWidget())->toolBarArea(this))
    16. 		{
    17. 		case Qt::LeftToolBarArea:
    18. 			expandButton->setArrowType(expanded? Qt::LeftArrow : Qt::RightArrow);
    19. 			break;
    20. 		case Qt::RightToolBarArea:
    21. 			expandButton->setArrowType(expanded? Qt::RightArrow : Qt::LeftArrow);
    22. 			break;
    23. 		case Qt::BottomToolBarArea:
    24. 			expandButton->setArrowType(expanded? Qt::DownArrow : Qt::UpArrow);
    25. 			break;
    26. 		case Qt::TopToolBarArea:
    27. 			expandButton->setArrowType(expanded? Qt::UpArrow : Qt::DownArrow);
    28. 			break;
    29. 		}
