高手你好，由于工作需要，做一个阵面监测的程序，
我在窗口上画的矩形没有任何显示，为什么？程序如下
int MyDetectWin::MyDraw(int left,int top,int width,int height)
{
ZafRegionStruct drawRegion ; //BeginDraw();
ZafDisplay *display = Display();
display->SetCoordinateType(ZAF_PIXEL);
BeginDraw();
drawRegion.left = 10;
drawRegion.top = 10;
drawRegion.right = drawRegion.left + 100;
drawRegion.bottom = drawRegion.top + 100;
display->SetBackground(ZAF_CLR_RED);
display->Rectangle(drawRegion,1,true);
//display->DestroyColor(color);
ZafPrompt *lable=new ZafPrompt(drawRegion.left,drawRegion.top,40, ZAF_ITEXT("prompt"));//prompt在界面上可以看到，说明执行了。
lable->SetCoordinateType(ZAF_PIXEL);
Add(lable);
EndDraw();
return 1;
}
但是用鼠标消息画的矩形却有显示：
ZafEventType MyDetectWin::Event(const ZafEventStruct &event)
{
ZafEventType ccode = LogicalEvent(event);
char buf[50];
ZafDisplay *replay = Display();
switch (ccode)
{
case L_BEGIN_SELECT:
{
ccode = ZafWindow::Event(event);
//WindowManager()->SetMouseEventRoute(this);//这一句会导致任何鼠标事件都发给她处理,破坏了
origin = event.position; //原来的路由方式.
replay->SetCoordinateType(ZAF_PIXEL);
origin_PIXEL = origin.Position(ZAF_PIXEL);
sprintf(buf,"%d",origin_PIXEL.column);
rowstring->SetText(ZAF_ITEXT(buf));
sprintf(buf,"%d",origin_PIXEL.line);
linestring->SetText(ZAF_ITEXT(buf));
BeginDraw();
ZafRegionStruct redrawRegion ;
redrawRegion.left = origin_PIXEL.column;
redrawRegion.top = origin_PIXEL.line;
redrawRegion.right = redrawRegion.left + CELLWIDTH;
redrawRegion.bottom = redrawRegion.top + CELLHEIGHT;
replay->SetBackground(ZAF_CLR_RED);
replay->Rectangle(redrawRegion,1,true);
EndDraw();
}
break;
default:
ccode = ZafWindow::Event(event);
}
return (ccode);
}
怎么办？
我需要画几十个矩形呢！！对了MyDetectWin是加在notebook上的。
MyTabBook::MyTabBook(int left ,int top,int width,int height)
:ZafNotebook(left, top, width, height)
{
SetCoordinateType(ZAF_PIXEL);
ZafWindow *page1 = new MyDetectWin(left,top,width,height);
page1->Add(new ZafTitle("Array Detect"));
Add(page1);
tableft = left;
tabtop = top;
tabwidth = width;
tabheight = height;
}
我感觉是画了，但是又被重画刷新了，怎么改？ |
