qt background color
To set the background color in a Qt application using C++, you can follow these steps:
Step 1: Include the necessary header files:
#include <QApplication>
#include <QWidget>
Step 2: Create a QWidget object:
QWidget *widget = new QWidget();
Step 3: Set the background color:
widget->setStyleSheet("background-color: red;");
Note: Replace "red" with the desired color name or a valid color code.
Step 4: Set the widget as the main window:
widget->show();
Step 5: Run the application event loop:
return QApplication::exec();
