Winforms issue with mouse over titles

[themullet]

There seems to be an issue of lack of mouse over title popups on image assets with winforms.

Tested on CefSharp.MinimalExample.WinForms and current CefSharp.WinForms.Example.

Is this doable from a configure setting or an issue?

Noticed title popups are ok on CefSharp.MinimalExample.Wpf

I dug a bit around upstreams and found: http://www.magpcss.org/ceforum/viewtopic.php?f=6&t=11514&p=20387&hilit=Tooltip#p20387 It looks like CefSharp WinForms could be missing some manifest info. If you succeed in getting it working a PR would be very welcome 👍

@jornh Looks like you were on the money again 😄 I've added to the WinForms Example app.manifest and tooltips now appear.

See a961cbd

Guess it's safe to mark as 39.0.0 and add to ChangeLog since it's fixed in CefSharp.WinForms.Example 👍 @amaitland you're too fast to let new people get in with such low hanging PRs 😜 Lol

@themullet you can close the issue if you agree this is fixed - thanks a bunch for noticing and reporting!

@jornh You may have a point, I should leave some 😄

FAQ entry required for this?

[jornh]

Hehe

FAQ entry required for this?

Nah, don't think so. I like that our FAQ is <= 10 points. Otherwise very few will bother reading it IMHO.

Maybe we should put a note with a link to the faq-able! issue type somewhere?

Excellent plan!

Impressive replys, thanks for the direction.

Just try to get working in Visual Studio, trying to find how to import Microsoft.windows.common-controls. Added a app.manifest to my project copied and pasted from https://code.google.com/p/chromiumembedded/source/browse/trunk/cef3/tests/cefsimple/cefsimple.exe.manifest getting could not find file on compile.

[amaitland]

You need to include the app.manifest in your project.

e.g. https://github.com/cefsharp/CefSharp/blob/master/CefSharp.WinForms.Example/CefSharp.WinForms.Example.csproj#L50

There's a menu item in Visual Studio, just google it, should be easy enough to find.

[themullet]

Added in the app.manifest and getting
Error 1 Could not find file 'Microsoft.Windows.Common-Controls, Version=6.0.0.0, Culture=, PublicKeyToken=6595b64144ccf1df, ProcessorArchitecture=, Type=Win32'. App Name

Sorry to thick on this.

[amaitland]

Try basing your app.manifest off https://github.com/cefsharp/CefSharp/blob/master/CefSharp.WinForms.Example/app.manifest

Seems the issue is on my end now, thanks a lot for the ultra quick response and help.

Awesome project, cheers for all your hard work.

[themullet]

Fixed the issue on my end now, disabled ClickOnce security settings and all ok now. Thanks again.

I realize this is an older issue but I'm having some trouble with the solution. By including the manifest, other controls outside of CEF are misbehaving. Anybody know how to apply the visualstyles stuff to CEF only and not to the rest of the application?

[jornh]

Have no experience with this and not really a CefSharp issue more a general Windows question I guess but https://msdn.microsoft.com/en-us/library/windows/desktop/bb773175%28v=vs.85%29.aspx#turnoff linked to above has a section on turning off the styling for a window or individual controls.

1. add app.manifest to vs project.

2. open the project *.csproj with notepad

   2.1 add code:

  <PropertyGroup>
    <ApplicationManifest>app.manifest</ApplicationManifest>
  </PropertyGroup>

2.2 modify code:

    <None Include="app.manifest">
      <SubType>Designer</SubType>
    </None>

[amaitland]

For reference VS has an Application Manifest File template. You can use the project properties to select the manifest. No manual editing required.
