[solved]Dynamically removing QPushButtons from Flowlayout

[neff]

Thank you for your reply.
Unfortunately the proposed correction doesn't solve the problem.
If I omit "flowlayout->update()" nothing in my program changes after I press the delete button (all Buttons remain in the flowlayout and all buttons still work). If I add "flowlayout->update()" to your correction, the program behaviour is the same as explained in the top post.

I tried a bit more and now I have the behaviour I aimed for with:

void MyWidget::deleteButton() {
 
    QLayoutItem *item = flowlayout->takeAt(0);
 
   if( item )
   {
      item->widget()->hide();
      delete item->widget();
      delete item;
    }
 
    qDebug() <<"deleted: "<<flowlayout->count();
}

void MyWidget::deleteButton() {

    QLayoutItem *item = flowlayout->takeAt(0);
   
   if( item )
   {
      item->widget()->hide();
      delete item->widget();
      delete item;
    }

    qDebug() <<"deleted: "<<flowlayout->count();
}

To copy to clipboard, switch view to plain text mode 

delete item->widget(); makes the button disappear from the layout.
item->widget()->hide(); makes sure that the buttons that are left get rearranged.
