KStatusNotifierItem 实例化使 Qt 崩溃

Question

我正在使用带有 Qt 5.11 的 Ubuntu Unity 17.04，并且在实例化 KStatusNotifierItem 时遇到了 Qt 崩溃的问题。

这是我的包含文件：

QT += widgets

HEADERS       =    
SOURCES       = main.cpp

# LIBS
LIBS += -lkdeui

# install
target.path = $$[HOME]/KSNITester
INSTALLS += target

这是我的来源：

#include <QApplication>
#include "kstatusnotifieritem.h"

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    KStatusNotifierItem * statusItem = new KStatusNotifierItem();
    return a.exec();
}

当我运行时，我得到一个 SIGSEGV 并且程序崩溃：

Starting /home/anshah/KSNITester/KSNITester...
The program has unexpectedly finished.
The process was ended forcefully.
/home/anshah/KSNITester/KSNITester crashed.

请告诉我如何解决此问题。

Answer 1

main.cpp:

#include <QApplication>
#include <QWidget>
#include <KStatusNotifierItem>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QWidget window;

    KStatusNotifierItem *sni = new KStatusNotifierItem(&window);
    sni->setCategory(KStatusNotifierItem::ApplicationStatus);
    sni->setIconByName("face-smile");
    sni->setTitle("KStatusNotifierItem Demo");

    window.show();

    return app.exec();
}

.pro 文件：

TEMPLATE = app
TARGET = ksnidemo
QT += widgets dbus KNotifications
SOURCES += main.cpp
