Form constructors

An other french

Hye,
I tried to implement a form class with 2 constructors.

Form::Form(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::Form)
{
    ui->setupUi(this);
}

Form::Form(Qstring & tmp, QWidget *parent) :
    QWidget(parent),
    ui(new Ui::Form)
{
    ui->setupUi(this);
    ui->textEdit->setText(tmp);
}


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

void Form::on_pushButton_clicked()
{
    this->close();
}

I found any example with 2 constructors.
I'm certain that i lost something somewhere....

I want to open this form at the beginning in the main.cpp and open it when i clicked on a button on the main form.

Ths for reading.

Why don't you just call the default Form constructor in your overloaded constructor:

Form::Form(QString &tmp, QWidget *parent) :
    Form(parent) 
{
    ui->textEdit->setText(tmp);
}

If you want to show the form, you can use the exec function - however, you need to change your base class to a QDialog:

Form myForm;
myForm.exec();

If you want to present a "Widget" :

In the main.cpp:

SEView w(&IK);
 w.show();

If you want to trigger the widgets showing with a click, I can use signals and slots:

QPushButton* button=new QPushButton;
Form* form= form("tmp",this);
connect(buitton,SIGNAL(clicked()),form,SLOT(show()));

The documentation is also helpful: http://doc.qt.io/qt-5/qwidget.html#show

I think that the form was destroyed when the function who constructs it , was ended.

void MainWindow::on_pushButton_3_clicked() 
{
    QString Txt = "ca fonctionne";
    Form viewNumber(Txt,0);
    viewNumber.show();
}

In fact, i need to pop up this window in certains conditions.
The solution to connect events together , seem to be difficult.
The automation isn't able to allow some logical purposes.

for example, if good result, show a smily else show a red devil.

In my case, when the com3 has some good setting, shows the form....

I'm clear, am i?

Do you think it 's faithful to put the form declaration as a pointor in the Private class of MainForm.h?

An other french

So, it seems to workwith a private pointor in form.h.

void MainWindow::on_pushButton_3_clicked() 
{
    QString Txt = "ca fonctionne";
    viewNumber= new Form(Titre);
    viewNumber->show();
}

Hi,

You are now leaking widgets each time you call that method.

What exactly do you want to do with it ? Is it a dialog ?
