Hi,
when i use a customized tilte bar in my unpackaged c++ app and i add a combobox, i can not click it.

Is this a bug?

 this->SetTitleBar(AppTitleBar());

There are some issues on GitHub, like Customized title bar isn't clickable in some cases (e.g. after decreasing window size) #2574

Hey Castorix,
I have another stupid question.
If there is a fix for C# packaged (they said it's fixed in 1.2 Preview 1), that doesn't mean it's also fixed for C++ unpackaged apps, right?
So i should create an issue on github?

I've tried it with 1.2 Preview 1 and also Preview 2 and it doesn't work or am i doing something wrong?!

Only by setting the "SetDragRectangle", the default titlebar appears and covers the customized titlebar.

auto titlebar = appWindow.TitleBar(); winrt::Windows::Graphics::RectInt32 rect[]{(0,0,1,1)}; titlebar.SetDragRectangles(rect);

Without setting the drag rectangle, the ComboBox is still not clickable. It's as described there, you can only click on the bottom line of the ComboBox and it reacts.

Can't upload a picture yet again but i installed 1.2.220930.4-preview2 by the Nuget Package Manager.

You mean that it works in C# (like samples from the doc :title-bar)
but it does not work in C++ ? (samples from GitHub cpp-winui that can be changed to unpackaged)
(I cannot test (Windows 10 with older App SDK version...))

Yes,
I already tried it with the mentioned SDK version. Even though they said that it's fixed in 1.2 Preview 1, it doesn't work.

I uploaded a test app on GitHub, if you can take a look? I've created the unpackaged app and installed 1.2 Preview 1 by the NuGet package manager. (This is the first time that i've used GitHub. Hope there is nothing wrong.)

As i said, the ComboBox only reacts by clicking in the area of the bottom line (maybe a little bit below or above).

I've added 2 videos which shows the 2 errors:

ADDENDUM:
I didn't test it in C#, i just trust the statements of the users in the post:

I cannot test on my PC (Windows 10 with App SDK 1.1.0 , no more space atm to install 1.2...)
As the issue #2574 was closed, maybe you could open a new issue on GitHub (at issues) with the link to your test project/issue
