There are OnGetViewRect and OnGetScreenInfo events in newer versions, but there is only 1st event in my version.
Using Demo code, I can set equal screen resolution and window's dimensions.
How can I set different resolution and dimension?
Thanks.

Using TChromium.OnGetViewRect you can configure CEF to use a surface with different dimmensions than your form to draw the web contents.

Read this page for more information about those events :

This only works in the OSR version, doesn't it?)

For the normal version only by script(

That's correct. All those events only work in OSR mode.

You are right, I am using OSR component. And want to set the size of screen and window.

If the CEF version you use doesn't have the OnGetScreenInfo event then you can't set a custom screen resolution.

You need to use a newer CEF version.

Code: Select all

// Screen resolution
procedure GetScreenInfo(Sender: TObject; const browser: ICefBrowser; var screenInfo: TCefScreenInfo; out   Result: Boolean);
var
  TempRect : TCEFRect;
begin
  if (GlobalCEFApp <> nil) then
    begin
      TempRect.x      := 0;
      TempRect.y      := 0;
      TempRect.width  := ScreenWidth[FCefID];
      TempRect.height := ScreenHeight[FCefID];

      screenInfo.device_scale_factor := GlobalCEFApp.DeviceScaleFactor;
      screenInfo.depth               := 0;
      screenInfo.depth_per_component := 0;
      screenInfo.is_monochrome       := Ord(False);
      screenInfo.rect                := TempRect;
      screenInfo.available_rect      := TempRect;

      Result := True;
    end
   else
    Result := False;
end;

// Browser's resolution
procedure GetViewRect(Sender : TObject;   const browser : ICefBrowser;  var   rect    : TCefRect);
begin
  if (GlobalCEFApp <> nil) then
    begin
      rect.x      := 0;
      rect.y      := 0;
      rect.width  := BrowsrWidth[FCefID];
      rect.height := BrowsrHeight[FCefID];
    end;
end;

After installation, use Chromium.WasResized;
