How to create and destroy browser form?

[andreykrasnodar]

Hello.
I have 2 forms in a project. Main form contains a lot of buttons and functions. The second form contains TChromium component.
A button on the main form should show (create/activate) 2nd form with TChromium, make some action and close (hide/destroy) form with TChromium after everything is done or timeout and free memory.
The next time the button should create form once again. And again and again.
I am not able to do it myself. Demos did not make it clear. Please help me.

Use the code in the ToolboxBrowser demo.

I use old version - 'Delphi Chromium Embeded 3'. I found ToolBoxBrowser on github.

CreateGlobalCEFApp;
if GlobalCEFApp.StartMainProcess then
begin
Application.Initialize;
Application.CreateForm(TMainForm, MainForm);
Application.Run;
end;
DestroyGlobalCEFApp;

There is an error Unit uCEFApplication not found

Check that CEF4Delphi's source directory is in the Delphi's library path :
https://www.briskbard.com/index.php?lan ... stallation
https://github.com/salvadordf/CEF4Delph ... -in-Delphi

Of course it is in the Delphi's library path. But there is no uCEFApplication in it

You should have this file in the "CEF4Delphi\source" directory :
https://github.com/salvadordf/CEF4Delph ... cation.pas

"CEF4Delphi\source" should also be added to the library path for 32 bits projects and 64 bits projects in the Delphi configuration window.
This is a common issue in Delphi because the configuration window shows the library path for 64 bits projects by default and most of the demos have a 32 bit target by default.

But I use Cef 3 (old version) https://github.com/hgourvest/dcef3 . I need it to create project for Windows XP.

I used simple code

Code: Select all

  Form1.Show;
  Form1.Delay(5000);// my own procedure like sleep(), but does not load processor
  form1.Chromium1.Load('yandex.ru');
  Form1.Delay(100000);
  form1.Chromium1.Load('about:blank');
  Form1.Delay(10000);
  Application.Terminate;

But after terminating the application it is still in task manager and eats my memory.

I'm sorry I missed that.

Consider using OldCEF4Delphi if you need to support Windows XP :
https://github.com/salvadordf/OldCEF4Delphi

It also has a ToolboxBrowser demo.

Thanks. But... can I do that with cef3?
