I have an application that I wrote using Qt 5.6.0. It's working fine on my Windows 10 x64. I created a cross-compiler on my Windows 10 host in order to compile code to my Raspberry Pi 1 B+. The cross-compiler is working good but when I execute my application on Raspberry Pi the window's title and all window's buttons (maximize, minimize and close) don't show up.
I can't move the window or resize it. Does someone have any ideia.
PS: I tried to run my application using all -platform parameters option and it still behaviors the same way.

Introduction
I'm currently creating an arcade cabinet project, so I used a Raspberry Pi 4 B or Raspberry Pi 3 B for this.
The game is running on a web application.
Problem
I wanted to start the web application directly on full screen when igniting the Raspberry Pi, without PC sensation (OS authentication, OS desktop).
Question
Does someone know how to start the web application directly on full screen when igniting the Raspberry Pi?
Open terminal write this code
sudo nano /etc/xdg/lxsession/LXDE-pi/autostart
then ;
#chromium-browser --start-fullscreen http://localhost **full screen
#chromium-browser --kiosk --disable-infobars http://localhost **full screen and no error
and CTRL+X , reboot...
I installed "onboard" as a virtual keyboard on the system. It looked much nicer and more useful than matchbox. I went into the settings and chose the auto open option when I edit the post. after that i restarted my raspberry pi. As it didn't come on automatically, I couldn't run it from the terminal or the menu normally. The error I get when I try to run it from terminal
Hej blackmamba,
I had the same issue with the on screen keyboard florence. After I installed at-spi2-core, it didn't crash anymore, though i could not get it to open automatically.
So I tried installing onboard and everything worked quiet well. Might be a hint..

I want to run my GUI in Raspberry PI but i dont want Raspberry PI's desktop to seen and Nobody can acces the desktop or my codes. Is that possible? if it is how ?
by the way i coded my gui by Python and Pyqt.
My raspberry pi is installed with the latest raspbian image, and now I am trying to program my SenseHAT. The status is :
The firmware boots up successfully, the rainbow is displayed on the
screen and Sense HAT, and it proceeds.
The OS(up-to-date raspbian) start loading with the splash screen, but
it is stuck at somewhere when it says udisks2.service,
All the OS modules are installed,
I2C is enabled at /boot/config.txt
dt_overlay is configured at /boot/config.txt.
Anybody has faced this freezing problem before? My raspberry pi 3 and Sense HAT simply not getting along with each other.
I have a Raspberry Pi 4B running under NOOBS. I have installed XRDP to be able to access the Raspberry from Windows.
The remote connection is working fine but whenever I launch an application (ex: Chromium) from Windows, I don't see anything happening. If I check directly on the screen connected on the Raspberry, I see that the application is running there.
It looks like whatever I launch on the remote desktop screen, the output goes to the native screen and I can't see it in the remote desktop window. I'm connected with exactly the same user on both sides.
Do you have any idea how to solve this?
Raspberry is known for not beeing compatible with any VNC Software.
You should try RealVNC first which comes with NOOBS. Make sure you have the latest version.
sudo apt-get update
sudo apt-get install realvnc-vnc-server realvnc-vnc-viewer
At your desktop select Menu > Preferences > Raspberry Pi Configuration > Interfaces.
Ensure that VNC is Enabled.
Now get your RealVNC Application for Windows and youre ready to go.
Another alternative is TightVNC, which works in most cases fine, too.
