aardio - 虚表 —— 把整行背景作为进度条的方法

1、单线程顺序下载演示：

import win.ui;
import godking.vlistEx;
/*DSG{{*/
mainForm = win.form(text="vlistEx - table adapter";right=551;bottom=423)
mainForm.add(
vlist={cls="vlistEx";left=10;top=10;right=544;bottom=416;border=1;db=1;dl=1;dr=1;dt=1;transparent=1;z=1}
)
/*}}*/

var t = { fields={"序号","姓名","年龄","地址","政治面貌"} };
for(i=1;10;1){
    var tt={};
    tt["序号"]="[@rowindex]";
    tt["姓名"]=math.random(1000,9999)+"姓名";
    tt["年龄"]=math.random(10,99);
    tt["地址"]=math.random(1000,9999)+"地址";
    tt["政治面貌"]="党员";
    ..table.push(t,tt);
}
mainForm.vlist.setTable(t,,-1,1);
mainForm.vlist.padding = 0;
mainForm.show();
var pros = {};
var crow = 1;
mainForm.setInterval( 
    function(){
        pros[crow] = (pros[crow]:0)+1;
        mainForm.vlist.redrawRow(crow);
        if pros[crow]=100 crow++;
        if crow>mainForm.vlist.count {
            ..win.msgbox("下载完毕");
            return false; 
        }
    },10
)
mainForm.vlist.onDrawCellRectBg = function(row,col,hdc,rect,bkcolor,text){
    var pro = pros[row]:0;
    if !pro return ; 
    if rect.left<0 rect.left=0;
    if rect.right>owner.width*(pro/100) rect.right=owner.width*(pro/100);
    if rect.right>rect.left {
        gdi.fillRect(hdc,pro=100?0x90EE90:0x7AA0FF,rect);
        return true; 
    }
}
win.loopMessage();

2、多线程同时下载演示：

 

import win.ui;
import godking.vlistEx;
/*DSG{{*/
mainForm = win.form(text="vlistEx - table adapter";right=551;bottom=423)
mainForm.add(
vlist={cls="vlistEx";left=10;top=10;right=544;bottom=416;border=1;db=1;dl=1;dr=1;dt=1;transparent=1;z=1}
)
/*}}*/

var t = { fields={"序号","姓名","年龄","地址","政治面貌"} };
for(i=1;10;1){
    var tt={};
    tt["序号"]="[@rowindex]";
    tt["姓名"]=math.random(1000,9999)+"姓名";
    tt["年龄"]=math.random(10,99);
    tt["地址"]=math.random(1000,9999)+"地址";
    tt["政治面貌"]="党员";
    ..table.push(t,tt);
}
mainForm.vlist.setTable(t,,-1,1);
mainForm.show();
mainForm.vlist.onDrawCellRectBg = function(row,col,hdc,rect,bkcolor,text){
    rect.inflate(mainForm.vlist.padding,0);
    var pro = owner.getRowMeta(row /*行号*/)["jindu"];
    if !pro return ; 
    if rect.left<0 rect.left=0;
    if rect.right>owner.width*(pro/100) rect.right=owner.width*(pro/100);
    if rect.right>rect.left {
        gdi.fillRect(hdc,pro=100?0x90EE90:0x7AA0FF,rect);
        return true; 
    }
}
for(i=1;mainForm.vlist.count;1){
    mainForm.vlist.addRowMeta(i /*行号*/,"jindu"/*属性名称*/,0/*属性值*/);
    thread.invoke( 
        function(mainForm,row){
            do{
                var jindu = mainForm.vlist.getRowMeta(row /*行号*/)["jindu"];
                jindu += math.random(0,1);
                mainForm.vlist.addRowMeta(row /*行号*/,"jindu"/*属性名称*/,jindu/*属性值*/);
                mainForm.vlist.redrawRow(row); 
                if jindu=100 return ;
                thread.delay(10);
            }while(true)
        },mainForm,i
    )
}
win.loopMessage();
