I have a TPanel that is set to AutoSize itself to its contents (Panel is green): When the TPanel contains any other control, e.g. a TListView , the panel will auto-size itself to the size of the contained listview: But when the contained control is a TWebBrowser (or the replacement TEmbeddedWB), the panel will not auto-size: Must be TWebBrowser's fault There must be some VCL plumbing needed for auto-sizing that the TWebBrowser

问题 I've found many ways to make the TWebBrowser show a modeless print dialog box, but how do I make it show a modal one? I would like to print an html page, that's why I need the modal dialog.
