Unsolved QSystemTrayIcon does not seem.

[Ibrahim]

Hi; I am using QSystemTrayIcon but icon does not seem. My code:

QSystemTrayIcon* tray_icon = new QSystemTrayIcon;
tray_icon->setToolTip("Hello World!");
tray_icon->showMessage(tr("Message Title"), tr("Hello Everbody!"), QSystemTrayIcon::Critical);
tray_icon->setVisible(true);

Thanks.

first thing to do:
"check whether a system tray is present on the user's desktop, call the QSystemTrayIcon::isSystemTrayAvailable() static function."

if check did not fail mostly likely button is there you just see no icon cause you did not set any.

#include <QSystemTrayIcon>
#include <QIcon>
#include <QDebug>
#include <QApplication>

............
QSystemTrayIcon* tray_icon = new QSystemTrayIcon (this );
tray_icon->setToolTip("Hello World!");

QIcon icon = QApplication::style()->standardIcon( QStyle::SP_ComputerIcon ) ;
Q_ASSERT( !icon.isNull() );

tray_icon->setIcon( icon );
tray_icon->show();
tray_icon->showMessage(tr("Message Title"), tr("Hello Everbody!"), QSystemTrayIcon::Critical );

@alex_malyu thanks. Can I use that in mobile applications (like notification)?

QSystemTrayIcon::isSystemTrayAvailable()

I have no experience, I think if QSystemTrayIcon::isSystemTrayAvailable() returns there true you can, otherwise you can't.
