@ohos.window 的API 【findWindow】与【setWindowBackgroundColor】设置窗口透明背景颜色导致窗口不显示

let dialogConfig: window.Configuration = {  
  name: 'webKeyboard',  
  ctx: getContext(this),  
  windowType: window.WindowType.TYPE_DIALOG  
}  
  
window.createWindow(dialogConfig, (err, win) => {  
  win.resize(this.deviceInfo.width, this.deviceInfo.height);  
  win.moveWindowTo(0, 0)  
  win.setUIContent(path);  
  
  win.showWindow((err) => {  
    if (err.code) {  
      // console.error('Failed to show the window. Cause: ' + JSON.stringify(err));  
    }else {  
      // console.info('Succeeded in showing the window.');  
      let windowClass: window.Window = window.findWindow("webKeyboard");  
      windowClass.setWindowBackgroundColor('#00000000')  
      windowClass.setWindowTouchable(true);  
    }  
  
  })  
})
