Hi All,
In a web browser I've built with Cef4Delphi support, it works fine if
I open the developer console without a parent.

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TForm_WSBrowser.SetDebugToolsEnabled;var  inspectElementAt:
Classes.TPoint;begin   Panel1.Visible:=not Panel1.Visible; 
 Splitter1.Visible:=Panel1.Visible;   if not DevToolCC then   begin 
 inspectElementAt:=Classes.Point(high(integer), high(integer)); 
 Chromium1.ShowDevTools(inspectElementAt,Panel1 {No problem if I type
nil});   DevToolCC:=true   end;end;   
But if I view this console on the Panel in the MainForm, there are
problems such as resizing and residual drawings on the screen.
When the panel is resized, what do I need to do to make the controls
in it correct themselves accordingly.

Panel1 needs to be a TCEFWindowParent and not a TPanel.

Check the MiniBrowser demo for all the details about showing, hiding
and resizing the DevTools.

Thank you so much for your reply salvadordf
I seem to remember that somewhere the size can be adjusted with the
handle values. Therefore, I thought the problem was related to
windows.
Magic Control ; Code: Pascal  [Select][+][-]window.onload =
function(){var x1 = document.getElementById("main_content_section");
if (x1) { var x = document.getElementsByClassName("geshi");for (var i
= 0; i TCEFWindowParentYes, this solved my problem. Not only did it
solve it;
It reminded me of the saying, "With every difficulty, there is an
ease".
