#include#include int main() { QRectF rect(10.0, 10.0, 20.0, 30.0); // Define a QRectF object rect.adjust(5.0, -10.0, -5.0, 10.0); // Adjust its boundaries return 0; }
#includeIn this example, we create a QRectF object with the position (10.0, 10.0) and size (20.0, 30.0). We then create a QSizeF object with width 10.0 and height -20.0. We call the 'adjust' function with arguments (-10.0, 20.0, 10.0, -20.0), which will adjust the boundaries of the QRectF object based on the dimensions of the QSizeF object. Both of these examples use the QtGui package in the Qt library.#include #include int main() { QRectF rect(10.0, 10.0, 20.0, 30.0); // Define a QRectF object QSizeF sizeAdjustment(10.0, -20.0); // Define a QSizeF object for adjustment rect.adjust(-sizeAdjustment.width(), -sizeAdjustment.height(), sizeAdjustment.width(), sizeAdjustment.height()); // Adjust its boundaries return 0; }
