Setting screen and windows dimentions in old CEF

[andreykrasnodar]

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.

Please help me

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.

It was my know-how

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;
