@serkan_tr I happend to know the source code a bit. You may try to replace the two lines(line 27 and 28):

    minimumWidth:   ScreenTools.isMobile ? Screen.width  : Math.min(ScreenTools.defaultFontPixelWidth * 100, Screen.width)
    minimumHeight:  ScreenTools.isMobile ? Screen.height : Math.min(ScreenTools.defaultFontPixelWidth * 50, Screen.height)

of the code here
https://github.com/mavlink/qgroundcontrol/blob/master/src/ui/MainRootWindow.qml
with
visibility: Window.FullScreen
to see if it helps.

[serkan_tr]

@serkan_tr said in How to make full screen:

if (!ScreenTools.isMobile || Screen.height / ScreenTools.realPixelDensity < 120 /|| 1 === 1/) {
console.log("APP: true")
// mainWindow.FullScreen
mainWindow.showFullScreen()

    } else {
        console.log("APP: false")
        width   = ScreenTools.isMobile ? Screen.width  : Math.min(250 * Screen.pixelDensity, Screen.width)
        height  = ScreenTools.isMobile ? Screen.height : Math.min(150 * Screen.pixelDensity, Screen.height)

// mainWindow.showFullScreen()
}
I guess this is what I'm doing. Even if I put "mainWindow.showFullScreen()" else here, it doesn't work, the bottom part is still visible.
My goal is to show the inside of my app as it was before formatting the tablet. I want it to completely fill the screen. no matter what device, tablet phone computer only this one should appear

[serkan_tr]

@JoeCFD I tried changing these lines but the screen size still did not change.
what exactly should i write

[JoeCFD]

@serkan_tr can you show your picture? I use it for Linux and Android without issues. Maybe Windows 10 is too old.
mainWindow.showFullScreen() is not needed.

You can also try to get screen size from your main and set it somewhere.
QRect rec = QGuiApplication::screens().at( 0 )->geometry();
QSize( rec.width(), rec.height() ) is the screen size;

then, pass the size to
height and width of your mainWindow

[serkan_tr]

@JoeCFD
27 and 28 no matter what I do, only the smallest state changes
The "windows taskbar" part at the bottom still appears

[JoeCFD]

@serkan_tr I said remove or comment them out.
Use only
visibility: Window.FullScreen

[serkan_tr]

@JoeCFD I made the comments line everywhere, I only made the part you said active, but it is still full screen, the vindow and application parts are visible at the bottom.
