This class is a composition of two QSettings instances:
Definition: qgssettings.h:55
static void show(const QgsError &error, const QString &title, QWidget *parent=nullptr, Qt::WindowFlags fl=QgsGuiUtils::ModalDialogFlags)
Show dialog with error.
void setValue(const QString &key, const QVariant &value, const QgsSettings::Section section=QgsSettings::NoSection)
Sets the value of setting key to value.
QString summary() const
Short error description, usually the first error in chain, the real error.
Definition: qgserror.cpp:128
QString message(QgsErrorMessage::Format format=QgsErrorMessage::Html) const
Full error messages description.
Definition: qgserror.cpp:49
QgsErrorDialog(const QgsError &error, const QString &title, QWidget *parent=nullptr, Qt::WindowFlags fl=QgsGuiUtils::ModalDialogFlags)
QgsErrorDialog constructor for QgsErrorDialog.
QgsError is container for error messages (report).
Definition: qgserror.h:83
QVariant value(const QString &key, const QVariant &defaultValue=QVariant(), const Section section=NoSection) const
Returns the value for setting key.
