Creo二次开发UI开发（2）：常用控件使用方法

uifcPushButton

常用动作：

• OnActivate()——点击按钮触发
• OnMouseEnter()——鼠标悬停触发
• OnMouseExit()——鼠标离开触发

1. 按钮可以在 UI Editor 中创建，toolkit 中直接用 uifcPushButtonFind()获取句柄。

uifcPushButton_ptr btn_workdir = uifcPushButtonFind(DialogName, "btn_workdir");
btn_workdir->AddActionListener(new SelectDir("ip_workdir", true));

class SelectDir : public uifcDefaultPushButtonListener
{
private:
  xstring name;
  bool flag; //是否更改工作目录
  public:
      SelectDir(xstring component, bool changed = false)
      {
          name = component;
          flag = changed;
      }

  public:
      void OnActivate(uifcPushButton_ptr handle)
      {
          pfcSession_ptr session = pfcGetProESession();
          pfcDirectorySelectionOptions_ptr options;
          options = pfcDirectorySelectionOptions::Create();
          try
          {
              xstring dir = session->UISelectDirectory(options);
              if (dir != xstring())
              {
                  uifcInputPanel_ptr MyInputPanel = uifcInputPanelFind(handle->GetDialog(), name);
                  MyInputPanel->SetTextValue(dir);
                  if (flag)
                  {
                      session->ChangeDirectory(dir);
                  }
