Need help with QToolButton

[philipp1]

May be I dont understand something but how we can ti convert QToolButton to QToolBar?
For expierence I wrote your code: cannot convert 'QToolButton*' to 'QToolBar*' in initialization.

oh sorry that was my mistake.

I actually meant

void MainWindow::addButton()
    {
          QToolButton* tb = new QToolButton(DockLeft, "");
    }

void MainWindow::addButton()
    {
          QToolButton* tb = new QToolButton(DockLeft, "");
    }

To copy to clipboard, switch view to plain text mode 

Sorry once again.

Store toolbar_but as a member variable. The toolbar_but in addButton() is different than in addToolBar(). It's just a dangling pointer in addButton().

One button it creates.

It's strange.

They is no such constructor QToolButton(DockLeft, ""); (I did't find it)

oh, I am sorry once again

It should be

void MainWindow::addButton()
   {
         QToolButton* tb = new QToolButton(this);
   }

void MainWindow::addButton()
   {
         QToolButton* tb = new QToolButton(this);
   }

Actually I got confused because of the QToolBar consstructor that your are using.

The constructor that you are using is obsolete

void MainWindow::addToolBar()
{
      QToolBar* toolbar_but = new QToolBar("Open puctures",this, DockLeft , TRUE ,0);// this is obsolete
 
}

void MainWindow::addToolBar()
{
      QToolBar* toolbar_but = new QToolBar("Open puctures",this, DockLeft , TRUE ,0);// this is obsolete

}

To copy to clipboard, switch view to plain text mode 

you should rather be using

void MainWindow::addToolBar()
{
      QToolBar* toolbar_but = new QToolBar(this,0);
      toolbar_but->setLabel("Open Pictures");
}

void MainWindow::addToolBar()
{
      QToolBar* toolbar_but = new QToolBar(this,0);
      toolbar_but->setLabel("Open Pictures");
}

To copy to clipboard, switch view to plain text mode 

or may be the other one according to your need.
