CMake shows console

lincoln

Hi guys, I have a question about CMake, I made an app and when I run in QtCreator everything goes well, my question is when I generate the release, a cosnola is shown along with my app, why does this happen, and how can I avoid it.

Here my code:

#include "mainwindow.h"
#include "./ui_mainwindow.h"
#include <QMessageBox>
#include <QSqlDatabase>
#include <QSqlError>
#include <QSqlTableModel>


MainWindow::MainWindow(QWidget *parent)
  : QMainWindow(parent), ui(new Ui::MainWindow)
{
  ui->setupUi(this);
  QSqlDatabase db=QSqlDatabase::addDatabase("QPSQL");
  if(!db.isDriverAvailable("QPSQL")){
      QMessageBox::critical(this,qApp->applicationName(),db.lastError().text());
      return;
    }
  db.setDatabaseName("covid");
  db.setHostName("localhost");
  db.setPassword("12345678");
  db.setPort(5432);
  db.setUserName("postgres");
  if(!db.open()){
      QMessageBox::critical(this,qApp->applicationName(),db.lastError().text());
      return;
    }
  QMessageBox::information(this,qApp->applicationName(),"Todo bien");
}

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

  )
endif()

target_link_libraries(untitled1 PUBLIC Qt${QT_VERSION_MAJOR}::Sql)

here I show the windows that are shown every time I run the .exe

Hi,

For Windows you can add something like:

set_property(TARGET main PROPERTY WIN32_EXECUTABLE true)

There are other possibilities like set_target_properties, I'll let you decide what best fits your needs.
