QSystemTrayIcon和Windows8

Question

I writing app and have strange bug in tray class. Inside my class I using QSystemTrayIcon like

 tray = new QSystemTrayIcon(this);
 tray->setIcon(QIcon(":/gui/logo.png"));
 ...
 tray->show();

On WinXP and Windows7 it's working properly, but on Windows 8 icon is not displayed

    qDebug()<<"System TRAY:"<< QSystemTrayIcon::isSystemTrayAvailable();// outputs true

I use Qt5.1.1 MSVC 2012

Answer 1

我只是遇到了同样的问题，我从phyatt使用的解决方案是将imageformats文件夹复制到我的应用程序的plugins文件夹中，并且现在工作正常。

Answer 2

Whether or not the system tray icon loads, I have found is more dependent on if it can load the file type.

Is the appropriate plugin available in your deployment environment?

Hope that helps.

UPDATE: Qt 5.1 w/ msvc 2012 32bit test results of QSystemTrayIcon on Windows 8 Pro: Compiling and building the test application with the following in a stock UI Form project, with the following in the mainwindow.cpp

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QSystemTrayIcon>

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    QSystemTrayIcon * sys = new QSystemTrayIcon(this);
//    sys->setIcon(QIcon("C:/Users/phyatt/Downloads/system-tray.png"));
    sys->setIcon(QIcon(":/gui/system-tray.png"));
    sys->show();
}

MainWindow::~MainWindow()
{
    delete ui;
}

And with these dependencies next to the exe, it runs just fine.
