如何在IupAnimatedLabel中显示循环进度IUP_CircleProgressAnimation

Question

这是最小的工作代码：

require("iuplua")
require( "iupluacontrols" )
require("iupluaimglib")
label_1 = iup.label {title = "The label                "}
label_2 = iup.label {image = "IUP_ActionOk"}
-- NOT WORK 
--label_3 = iup.AnimatedLabel(NULL);
--iup.SetAttribute(label, "ANIMATION", "IUP_CircleProgressAnimation");
--iup.SetAttribute(label, "START", "Yes");
vbox = iup.vbox{
                 label_1
                ,label_2
                --, label_3
}

dlg = iup.dialog{
  vbox
}

dlg:showxy(iup.CENTER,iup.CENTER)
dlg.usersize = nil
-- to be able to run this script inside another context
if (iup.MainLoopLevel()==0) then
  iup.MainLoop()
  iup.Close()
end

该示例取自帮助，但不幸的是，评论的内容不起作用。

Answer 1

使用以下代码：

label_3 = iup.animatedlabel{}
label_3.animation = "IUP_CircleProgressAnimation"
label_3.start = "Yes"

刚刚测试过，您的样品工作正常。
