I'm going to change the title and color of the title bar, what am I doing wrong?

1. How can I change the title for the 'MainPage' bar (see file: S0.png)
2. How can I replace the light to dark color for the 'MediaView' (see file: S1.png)

I will be grateful in advance for the tips. Greeting.

It works if you explicitly set the darkmode to the PageMediaView after it is displayed, may need tweaking if you do anything else with the page.

In Main.Button1_Click add the last line:

B4X: 
        B4XPages.MainPage.pg.pth = File.GetFileParent(ffplay)
        B4XPages.MainPage.pg.filename = File.GetName(ffplay)
        B4XPages.ShowPage("PageMediaView")
        DarkTitleBar.SetDarkMode(B4XPages.GetNativeParent(B4XPages.GetPage("PageMediaView")),True)

It needs setting for each new page.

You have two options.
Either you use MainForm.SetFormStyle("UNDECORATED") and create the title bar yourself,
or you can use this:

Dark Title Bar (Windows only)

Another option for a Dark Title Bar I found some code on StackOverflow which I got working in B4j: It depends on JNA 5 + available on Github. Although it's probably easier to get them from Maven Central #AdditionalJar: jna-5.16.0 #AdditionalJar: jna-platform-5.16.0 I have tested on Win...

I don't know if it's possible to change the title color with this class.

I used the method you mentioned in my example. For forms it's simple, but for B4XPages it doesn't work.

Could you provide a code example that demonstrates the problem?
It will be easier to see what's wrong.

The demo example attached to the post (B4XPages.zip) shows my problem. I also wanted to get a dark title color for the MediaView window. Currently you only see a dark background for the title in MainPage. @stevel05 suggestion is right, it made me realize that the settings should be made for each new page. Now everything is clear, you can close the resolved topic - thanks for your response and help
