特别提醒:
aardio作者已在aardio v25.81之后版本增加了调用IFileOpenDialog接口打开文件夹选择框的功能, 只需要调用以下代码:
import com.interface.IFileOpenDialog; var path = com.interface.IFileOpenDialog.dir(,winform,'请选择目录')
相关的范例在
用法参考：aardio范例 / 文件操作 / 文件对话框
查看这个功能实现代码,同时也可以学习com.interface接口的用法.
感谢aardio培训群: 心在安 分享dll和方案
我们知道在aardio里目前dlg.opendir() 打开的对话框是默认的小框
如下图:
我们下面利用 分享的dll来实现如下图的对话框
代码如下:
import win.ui;
/*DSG{{*/
mainForm = win.form(text="aardio工程14";right=759;bottom=375)
mainForm.add(
button={cls="button";text="Button";left=216;top=226;right=571;bottom=317;z=1};
edit={cls="edit";left=178;top=46;right=570;bottom=181;edge=1;multiline=1;z=2}
)
/*}}*/
var dll = ..raw.loadDll("\res\NewFolderPicker.dll","picklib","cdecl,unicode");
PickAFolder = dll.api("PickAFolder","void(pointer& path)" );
var GetFloder = function(){
var path = PickAFolder(null);
if(path!=null){
var pathStr = raw.tostring(path,1,520);
var PpathStr = string.split(pathStr);
var retstr;
for(i=1;520;1){
if(PpathStr[i]!='\0'){
retstr = string.concat(retstr,PpathStr[i]);
}else {
if(PpathStr[i+1]=='\0'){
break;
}
}
}
return retstr;
}
return null;
}
import console
console.open()
mainForm.button.oncommand = function(id,event){
var path = GetFloder()
console.log(path)
}
mainForm.show();
return win.loopMessage();dll下载:
生成dll的vc2019工程源码如下:

备注:
以上生成dll是采用的com方式使用IFileOpenDialog接口实现,所以应该可以用com.interface实现同样的功能.
参考如下:

有机会com.interface方式实现后,同样会分享到楼下.

感谢aardio群: fish 提供com静态接口版本源码
