#include#include // Open the configuration file KConfig config("myapp.conf"); // Get the main group KConfigGroup mainGroup = config.group("main"); // Get a reference to a value in the configuration KValueRef valueRef = mainGroup.readEntry("myValue"); // Modify the value valueRef = 42; // Save the configuration back to disk config.sync();
#includeIn this example, the code creates a checkbox and gets a reference to its "isChecked" value using KValueRef. The value is then modified to true and connected to a slot that will be called whenever the value changes. Overall, KValueRef is a very useful class for handling values in KDE applications and can be used for a wide range of tasks, from reading and writing configuration files to managing user interface elements.#include // Create a checkbox QCheckBox *myCheckBox = new QCheckBox("My Checkbox"); // Get a reference to the checkbox's value KValueRef valueRef = myCheckBox->isChecked(); // Modify the value valueRef = true; // Connect the value to a slot connect(&valueRef, SIGNAL(valueChanged()), this, SLOT(onCheckBoxValueChanged()));
