I'm planning on building an application that simplifies web design. I intent using Lazarus/FreePascal for this.
My question is, how do I show HTML content on a Lazarus form as it would appear on the Browser?
Since FPC is cross-platform you will not know in advance what webbrowser a user will have installed so you cannot simply embed a TWebBroser.
There are some controls available that embed a specific engine like Gecko or Webkit. Read all about it on the wiki: http://wiki.freepascal.org/Webbrowser and especially in the last part of that page.
