MFC，對話方塊滾動條使用

不用管是什麼意思，我也不知道，能用就行，對話方塊中設定自動新增那種滾動條，在建立滾動條函式，複製貼上

橫向滾動條：onhscroll

scrollinfo scrollinfo;  

getscrollinfo(sb_horz,&scrollinfo,sif_all); 
switch (nsbcode) 
setscrollinfo(sb_horz,&scrollinfo,sif_all); 
scrollwindow(10,0); 
break; 
case sb_lineright: 
scrollinfo.npos += 1; 
if (scrollinfo.npos>scrollinfo.nmax) 
setscrollinfo(sb_horz,&scrollinfo,sif_all); 
scrollwindow(-10,0); 
break; 
case sb_pageleft: 
scrollinfo.npos -= 5; 
if (scrollinfo.npos)
setscrollinfo(sb_horz,&scrollinfo,sif_all); 
scrollwindow(10*5,0); 
break; 
case sb_pageright: 
scrollinfo.npos += 5; 
if (scrollinfo.npos>scrollinfo.nmax) 
setscrollinfo(sb_horz,&scrollinfo,sif_all); 
scrollwindow(-10*5,0); 
break; 
case sb_thumbposition: 
break; 
case sb_thumbtrack: 
scrollwindow((scrollinfo.npos-npos)*10,0); 
scrollinfo.npos = npos; 
setscrollinfo(sb_horz,&scrollinfo,sif_all); 
break; 
case sb_endscroll: 
break; 
}

垂直滾動條：onvscroll

scrollinfo scrollinfo;

getscrollinfo(sb_vert,&scrollinfo,sif_all); 
switch (nsbcode) 
setscrollinfo(sb_vert,&scrollinfo,sif_all); 
scrollwindow(0,10); 
break; 
case sb_linedown: 
scrollinfo.npos += 1; 
if (scrollinfo.npos>scrollinfo.nmax) 
setscrollinfo(sb_vert,&scrollinfo,sif_all); 
scrollwindow(0,-10); 
break; 
case sb_pageup: 
scrollinfo.npos -= 5; 
if (scrollinfo.npos)
setscrollinfo(sb_vert,&scrollinfo,sif_all); 
scrollwindow(0,10*5); 
break; 
case sb_pagedown: 
scrollinfo.npos += 5; 
if (scrollinfo.npos>scrollinfo.nmax) 
setscrollinfo(sb_vert,&scrollinfo,sif_all); 
scrollwindow(0,-10*5); 
break; 
case sb_endscroll: 
break; 
case sb_thumbposition: 
break; 
case sb_thumbtrack: 
scrollwindow(0,(scrollinfo.npos-npos)*10); 
scrollinfo.npos = npos; 
setscrollinfo(sb_vert,&scrollinfo,sif_all); 
break; 
}

mfc 帶滾動條的對話方塊 滾動條訊息響應方法

在對話方塊對應的類屬性裡新增onvscroll 裡面新增 如下 void picture parent dlg onvscroll uint nsbcode,uint npos,cscrollbar pscrollbar setscrollinfo sb vert,scrollinfo,sif al...

對話方塊中滾動條方便用

在對話方塊上要應用滾動條，首先當然是要將對話方塊的屬性vertical scroll選中 在這裡只介紹縱向滾動條，橫向滾動條與之原理相同 然後是按ctlr w進入classwizard選中對話訊息wm onvscroll，並新增它的響應函式，接著進入 編輯區，寫入 void crq onvscrol...
