Opening a new form with a push_button

[Gerrit Zijlstra]

I'm trying to open a new form with a push Button. i've seen examples on YouTube but can't get it working.

My main form is called: srm.ui
It has a button 'PB_driver_settings' And I want to open the form drivers.ui when I press the button.

In my srm.h I have included ui_drivers.h
and added a line in the private section:
private:
Ui::SRM *ui;
Ui_driver_update driver_update;

What should I do to make the correct call.
I don't know the argument to add.
void SRM::on_PB_Driver_Settings_clicked()
{
driver_update.setupUi();
}

I exampled I saw a call to a function .show() but that is not working either.

You don't need to include ui_* include files.

include drivers.h file in your srm.h file (you can do forward declaration but for simplicity lets not do that.

#include "driver.h"

Define a variable (preferrabley private) for Driver object.

Driver *driverWindow;

In SRM's constructor create the driverWindow object

driverWindow = new Driver(this);

and your slot:

void SRM::on_PB_Driver_Settings_clicked()
{
      driverWindow->exec();
}
