In this example, we are setting the single step value of spinBoxObj to 2, which means clicking the up/down arrow buttons will increase/decrease the value of spinBoxObj by 2. Example 2: Setting single step value to 0.1 for a QDoubleSpinBox object named doubleSpinBoxObj.c++
In this example, we are setting the single step value of doubleSpinBoxObj to 0.1, which means clicking the up/down arrow buttons will increase/decrease the value of doubleSpinBoxObj by 0.1. Example 3: Setting single step value to 100 for a QSpinBox object named spinBoxObj using the setValue() method.c++ spinBoxObj->setValue(0); // set initial value to 0 spinBoxObj->setSingleStep(100); // set single step value to 100 ``` In this example, we are setting the single step value of spinBoxObj to 100 using the setValue() method. The initial value of spinBoxObj is set to 0, so clicking the up arrow button will increase the value to 100, and subsequent clicks will increase the value by 100 each time. Package library: Qt Widgets module available in the Qt C++ library.
