c++ builder：从 TFramedVertScrollBox 中动态删除所有 TPanel

Question

在我的 C++ Builder 项目中，我有一个动态获取 TPanel 的 TFramedVertScrollBox (pnl_art_box)。我想在添加 "new" 之前清除所有现有的 TPanel。

for(int i = 0; i < this->pnl_art_box->ComponentCount; i++)
{
    // this here is where i dont find any solution ...
    this->pnl_art_box->Components[i]->DestroyComponents(); 
}
for(int i = 0; i < i_article_amount;i++)
{
    this->articlelistpanels[i] = new TPanel(this->pnl_art_box);
    this->articlelistlabels[i] = new TLabel(this);

    this->articlelistlabels[i]->Text = this->articlelist[i].get_name();
    this->articlelistpanels[i]->Align = Fmx::Types::TAlignLayout::MostTop;

    this->articlelistpanels[i]->AddObject(this->articlelistlabels[i]);
    this->pnl_art_box->AddObject(this->articlelistpanels[i]);
}

在 Google 我只找到了很少的帮助，其中 none 是用 C++ 编写的；

如果有人能在我做错时告诉我，那就太好了。

终于自己找到了。正确的命令是：

for(int i = 1; i < this->pnl_art_box->ComponentCount; i++)
{
    this->pnl_art_box->Components[i]->DisposeOf();
}
