[SOLVED] Looking for a cross-platform webbrowser component for Lazarus
maurobio:
Dear ALL,
Out of sheer curiosity, I would like to give a try to some of the existing webbrowser components for Lazarus.
I do understand that this can be a spiny question, as shown in this thread: https://forum.lazarus.freepascal.org/index.php/topic,26572.0.html
However, I feel like trying it myself!
I want a component which is cross-platform (at least supporting Linux and Windows). I would also prefer a component that is not based on Qt. So, I have been left with two choices: GeckoPort and fpCEF3. There are nice tutorials for for the former (https://lazplanet.blogspot.com/2013/10/browser-in-lazarus-with-gecko-pt1.html?m=1) and for the latter (https://lazplanet.blogspot.com/2015/09/create-web-browser-in-3-minutes-using.html?m=1).
First, I tried the GeckoPort component (which seems to be the nearest to my requirements). Following the tutorial from here (https://lazplanet.blogspot.com/2013/10/browser-in-lazarus-with-gecko-pt1.html?m=1), I downloaded version 1 of the component, as well as the required XULRunner runtime library. I had no problem in compiling and installing the package in the IDE, however when attempting to run the GBrowser demo, what I got was a sequence of blank screens (see the attached screenshot), instead of the Free Pascal home page as shown in the tutorial.
Second, I tried the fpCEF3 component, following the instructions from here: https://lazplanet.blogspot.com/2015/09/create-web-browser-in-3-minutes-using.html?m=1 (the "3-minutes solution"). In that case, the results were worse, because I could not even have the package compiled and installed in the IDE: it returned just a lot of compilation errors!
Could any of you wizards give me some hints on that matter?
Thanks in advance!
With warmest regards,

Ah, it seems to be an upgraded version of fpCEF3! I will give it a try.
Thank you very much!

Dear ALL,
In facrt, the CEF4Delphi component pointed out by Zvoni seems to be adequate to my needs, but I still have a (perhaps very lame) doubt: is there any way of loading a local file and/or a string list with HTML markup, as provided by the TWebBrowser component which comes with Lazarus?
Thanks in advance!
With best regards,

I am not familiar with the component and the information I got is based on sysrpl's repository (probably outdated)
Any webbrowser should be able to load (html) files using the file protocol so give that a spin.
Also in sysrpl's version is a method named LoadHtml, exactly for that purpose. I take it you are able to load a html file into a string...
