Step 1:
Layout the QT program, and then add the code to automatically set the screen size in the constructor. The code is as follows:
After setting it up, copy the QT code to Ubuntu.
#include
#include
#include
QDesktopWidget *deskTopWidget = QApplication::desktop();
QRect deskRect = deskTopWidget->availableGeometry();
int appH = deskRect.height();
int appW = deskRect.width();
this->setFixedSize(appW, appH);
setGeometry(0, 0, appW, appH);
The addition is completed as shown in Figure 62.3.4.1:

Step 2:
Enter the project folder directory to be compiled, and directly use the qmake under the qt source code we compiled on Ubuntu to generate the Makefile, enter: /opt/qt5.7.0/bin/qmake

Step 3:
After successfully generating the Makefile, you can directly use make to compile it. After the compilation is successful, the executable file obtained can be run on the development board.
