I successfully added AcroPDF in my application. When a PDF needs to be displayed I create an instance of AcroPDF dynamically and insert it into a TPanel with align set to alClient. My problem is that when the Form/Panel is resized the AcroPDF does not follow. Only if a new file is loaded. I tried several solutions to no avail. What should I do?

推荐答案

最新版本的Adobe OCX控件存在问题，您可以通过重新调整控件的位置来解决该问题.在预览对话框中(具有嵌入式的，与客户端对齐的AcroPdf控件)，我在表单中使用以下 OnResize 处理程序:

It's a problem with recent versions of the Adobe OCX control, which you can work around by refocusing the control. In a preview dialog I have (which has an embedded, client-aligned AcroPdf control) I use the following OnResize handler for the form:

if Visible and (fPreviewV7 <> nil) then begin
  FocusControl(nil);
  FocusControl(fPreviewV7);
end;
