请教:TreeView控件中indent()与picturetype()表示什么?
如下代码,其中indent()与picturetype()它表示什么?何处能找到它的用法?this.additem('市县选择')
this.indent(this.listcount-1)=0
this.picturetype(this.listcount-1)=1 &&打开
do while !eof()
dsdm0=sdm
this.additem(sdm+' '+sdmc) &&市地
this.indent(this.listcount-1)=1
this.picturetype(this.listcount-1)=0 &&关闭
this.additem(sxdm+' '+sxmc) &&县区
this.indent(this.listcount-1)=2
this.picturetype(this.listcount-1)=2 &&树叶
skip
do while sdm=dsdm0 and !eof()
this.additem(sxdm+' '+sxmc) &&县区
this.indent(this.listcount-1)=2
this.picturetype(this.listcount-1)=2 &&树叶
dsdm0=sdm
skip
endd
endd
