[SOLVED] Put application on notification bar.

[vibolvireak]

@Hamed-Masafi I'm really thank you for your help. Do you know how to hide and application if user click on close bt on the top-right of the windows ?

Hi and welcome to devnet,

you could try to reimplement the QWidget::closeEvent() then call hide() and reject the event.

Anyway you have to provide a way to really quit from you application.

@mcosta Hello, thank for help :) let me apology for less education with c++ i just start today. I have append the code MainWindow.cpp

void MainWindow::closeEvent(QCloseEvent *event){

}

And i got error message
no 'void MainWindow::closeEvent(QCloseEvent*)' member function declared in class 'MainWindow'

I'm thank for help

[mcosta]

Hi,

you have to put

void closeEvent(QCloseEvent*);

in the protected part of your class declaration

*@mcosta Hello i have put void closeEvent(QCloseEvent); on the protected line of my header file. And the run look successfully however. i got error message when i try to use event->ignore(); in

void MainWindow::closeEvent(QCloseEvent *event){
QMessageBox::information(this, "Comfirmed", "We will hide your application");
if(QMessageBox::Ok){
event->ignore();
}
}

[mcosta]

Your code should be like this

void MainWindow::closeEvent(QCloseEvent *event){
    int result = QMessageBox::information(this, "Comfirmed", "We will hide your application");
    if(QMessageBox::Ok == result) {
        event->ignore();
    }
}

anyway is better to post also the error.

@mcosta Obb look like i forgot. i got error "In member function 'virtual void MainWindow::closeEvent(QCloseEvent*)'"

[vibolvireak]

Update:
C:\Users\vibolvireak\Documents\Clossdrive\mainwindow.cpp:25: error: invalid use of incomplete type 'class QCloseEvent'
event->ignore();
^

[mcosta]

you have a missing include

#include <QCloseEvent>

NOTE: IMO you're some weakness in C++. I Suggest to study a little bit more the language
