The System Information example uses a tabbed dialog, with each tab representing a particular type of data: versions, network and so on.
To access the information, the example creates objects belonging to the System Information classes
Here are some examples that show how the example application reads the device information.
The current language
systemInfo = new QSystemInfo(this);
curLanguageLineEdit->setText( systemInfo->currentLanguage());
Device information, starting with the battery level
bi = new QSystemBatteryInfo(this);
...
chargerTypeChanged(bi->chargerType());
currentBatStat = bi->batteryStatus();
The battery status is an enum, QSystemBatteryInfo::BatteryStatus, that indicates various battery levels and their significance, e.g., QSystemBatteryInfo::BatteryVeryLow.
The manufacturer id and the product name
manufacturerLabel->setText(di->manufacturer());
...
productLabel->setText(di->productName());
Other information is stored as bitwise flags. The following code shows the input methods being determined using flags.
QSystemDeviceInfo::InputMethodFlags methods = di->inputMethodType();
QStringList inputs;
if ((methods & QSystemDeviceInfo::Keys)=QSystemDeviceInfo::Keypad){
inputs << "Keys";
}
if ((methods & QSystemDeviceInfo::Keypad)=QSystemDeviceInfo::Keypad) {
inputs << "Keypad";
}
Various capabilities of the device can be found by testing for features. In the example a Feature combo box, on the General tab, has a hard coded list of features. When a listed feature is selected the getFeature() function is called with the index which is handled by applying a test to the corresponding feature.
QSystemInfo::Feature feature;
switch(index) {
...
case 1:
feature = QSystemInfo::BluetoothFeature;
...
QSystemInfo si;
featuresLineEdit->setText((si.hasFeatureSupported(feature) ? "true":"false" ));
