This is my workaround:

Qt Code: 
  1. void listTab::changeTo(QString& it)
  2. {
  3. 	bool funkysb;
  4. 	int min;
  5. 	int max;
  6. 	int range;
  7. 	int row;
  8. 	int r;
  9. 	int c = ui.listWidget->count();
  10. 	int v;
  11. 	QString number;
  13.  
  14. 	sb = ui.listWidget->verticalScrollBar();
  15. 	min = sb->minimum();
  16. 	max = sb->maximum();
  17. 	range = max - min;
  18.  
  19. 	funkysb = ((range == 0) && (c != 0));
  20. 	if (funkysb)
  21. 	{
  22. 		// The scrollbar range is zero and the control contains
  23. 		// items, set the scroll range to something useful
  24. 		min = 0;
  25. 		max = c - 1;
  26. 		range = max - min;
  27. 		sb->setRange(min, max);
  28. 	}
  29.  
  30. 	// Find the specified number in the list
  31. 	for (row = 0; row < c; row++)
  32. 	{
  33. 		number = ui.listWidget->item(row)->text();
  34.  
  35. 		if (number == it)
  36. 		{
  37. 			// Make it the current selection
  38. 			// This resets the scrollbar range to 0,0 if the
  39. 			// list is in a tab widget with a layout
  40. 			ui.listWidget->setCurrentRow(row);
  41. 			ui.listWidget->item(row)->setSelected(true);
  42.  
  43. 			// Reset the scrollbar range if we have funkiness
  44. 			r = sb->maximum() - sb->minimum();
  45. 			if (funkysb && (r != range))
  46. 			{
  47. 				sb->setRange(min, max);
  48.  
  49. 				// Scroll to the item
  50. 				sb = ui.listWidget->verticalScrollBar();
  51. 				r = (row + 1) * range;
  52. 				c = ui.listWidget->count();
  53. 				v = r / c;
  54. 				if (r % c)
  55. 				{
  56. 					v++;
  57. 				}
  58. 				sb->setValue(v);
  59. 			}
  60. 			break;
  61. 		}
  62. 	}
  63. }
