The code you need is next:
Supposing that you call your dialog for example from MainWindow::on_but_admin_clicked()function:
On mainwindow.cpp
void MainWindow::on_but_admin_clicked()
{
//Declare a private object in your mainwindow.h like this:
//login* objlogin;
objlogin = new login();
//Connect signals to later call the method setHiden(false)
QObject::connect(objlogin, SIGNAL(stackoverflowAnswer()), this, SLOT(makeVisible()));
objlogin->show();
}
//...
// The function that will be called from login dialog to enable hidden buttons
void MainWindow::makeVisible()
{
ui->but_save->setHidden(false);
ui->but_delete1->setHidden(false);
ui->but_delete2->setHidden(false);
ui->but_upload1->setHidden(false);
ui->but_upload2->setHidden(false);
}On login.cpp (on_ok_clicked() function):
void login::on_ok_clicked()
{
QString username = ui->username->text();
QString password = ui->password->text();
if(username == "123" && password == "123")
{
***HERE, after this block executed i want that buttons visible on mainwindow***
emit stackoverflowAnswer();
//...Remember to declare in login.h the signals and slots:
signals:
void stackoverflowAnswer();
private slots:
void on_ok_clicked();

I have one window which includes all the buttons and there are some buttons that are hidden.
Now I want set visibility to true from another dialog.
How to do it? I have googled it but I am unable to solve this problem.
And I want it appear after this dialog box get completed!
