QTableView和QTableWidget翻頁功能實現

 

       主要使用QTableView和QTableWidget中的三個函數實現

QTableView：：verticalScrollBar()->setSliderPosition()；  //設置當前滑動條的位置

QTableView：：verticalScrollBar()->maximum();             //滑動條能移動的最大位置

QTableView：：verticalScrollBar()->value();                   //獲得當前滑動條的位置

 

 

1. static int nCurScroller=0; //翻頁時的當時滑動條位置
2. static int pageValue = 10; // 一頁顯示條數
4. void SplayHisForm::createHisForm()
5. {
6.                 …….
   
7.     hisTableWidget = new QTableWidget;
8.     hisTableWidget->setSelectionMode(QAbstractItemView::SingleSelection);
   
9.     hisTableWidget->setSelectionBehavior(QAbstractItemView::SelectRows);
   
10.             …….
    
11. }
13. /***下一頁***/
14. void SplayHisForm::nextPageHis()
15. {
16.     int maxValue = hisTableWidget->verticalScrollBar()->maximum(); // 當前SCROLLER最大顯示值25
17.     nCurScroller = hisTableWidget->verticalScrollBar()->value(); //獲得當前scroller值
19.     if(nCurScroller<maxValue)
    
20.         hisTableWidget->verticalScrollBar()->setSliderPosition(pageValue+nCurScroller);
    
21.     else
    
22.         hisTableWidget->verticalScrollBar()->setSliderPosition(0);
    
23. }
25. /***上一頁***/
26. void SplayHisForm::prePageHis()
27. {
28.     int maxValue = hisTableWidget->verticalScrollBar()->maximum(); // 當前SCROLLER最大顯示值25
29.     nCurScroller = hisTableWidget->verticalScrollBar()->value();
    
31.     if(nCurScroller>0)
    
32.         hisTableWidget->verticalScrollBar()->setSliderPosition(nCurScroller-pageValue);
    
33.     else
    
34.         hisTableWidget->verticalScrollBar()->setSliderPosition(maxValue);
    
35. }
