【原创】关于ListView拖放刷新的BUG修改

在炫彩库源码listView.cpp中查找函数：void ListView_CalculateView(HELE hEle)，将代码替换如下：

1. 
   
2. //计算视图大小
   
3. void ListView_CalculateView(HELE hEle)
   
4. {
   
5. listView_ *pListView=(listView_*)hEle;
   
6. RECT rect;
   
7. XEle_GetClientRect(hEle,&rect);
   
8. int right=rect.right-XSView_GetSpacingRight(hEle);
   
9. right=right-XSView_GetScrollBarWidth(hEle);
   
10. int t1=XSView_GetSpacingLeft(hEle);
    
11. int t2=XSView_GetSpacingTop(hEle);
    
12. //计算分组项
    
13. int leftSpace=t1+pListView->leftAlign; //边框左间隔
    
14. int topSpace=t2+pListView->topAlign;  //边框上间隔
    
15. int x=leftSpace; //X叠加
    
16. int y=topSpace;  //Y叠加
    
17. int y2=topSpace; //计算每行最大的bottom值
    
18. int count=XArray_GetCount(pListView->hArrayList);
    
19. int countGroup=XArray_GetCount(pListView->hArrayGroupList);
    
20. int itemCX=pListView->iconSize.cx+pListView->left+pListView->right; //项宽度
    
21. //计算视图//////////////////////////////////////////////////

重新编译后就OK了

不错，试一下看。
