Hi guys,

i try to do this simple animation:



the layout of window is grid (for window autoresize).

the first animation where frame 1 go out run correctly, but the second animation where frame 2 go inside the window not run correctly... the animation flicker...

this is the code:
[where:
Button 1=ButtonLogin;
Frame 1= login;
frame 2= linkedin;]

Qt Code: 
  1. //QWidget_home.cpp
  2.  
  3. Home::Home(QWidget *parent) :
  4.     QWidget(parent),
  5.     ui(new Ui::Home)
  6. {
  7.     ui->setupUi(this);
  8.     inizio();
  9. }
  10.  
  11. void Home::inizio()
  12.     {
  13.             databaseOn(); //read data from sql Database
  14.             hideall();
  15.             ui->Login->show(); //show the frame 1
  16.  
  17.             //set the image and labels in all frame
  18.             QPixmap immagine(":/immagine1.jpg");
  19.             ui->labelimage->setPixmap(immagine);
  20.             QPixmap immaginelogin(":/loginlogo.png");
  21.             ui->labelloginimage->setPixmap(immaginelogin);
  22.             ui->linePassword->setEchoMode(QLineEdit::Password);
  23.             QPixmap immaginewelcome(":/welcome.png");
  24.             ui->labelWelcome->setPixmap(immaginewelcome);
  25.    }
  26.  
  27. void Home::hideall(){ //hide all 
  28.     ui->Login->hide();
  29.     ui->Linkedin->hide();
  30.     ui->ModificaProfilo->hide();
  31. }
  32.  
  33. //[...]
  34.  
  35. void Home::on_pushButtonLogin_clicked()
  36. {
  37.  
  38.     //convert data in form for the database (is a vector)
  39.     bool logged=true;
  40.     QString * s= new QString[2];
  41.     s[0]=ui->lineUsername->text();
  42.     s[1]=ui->linePassword->text();
  43.     try{
  44.         cercami(s);
  45.     }catch (errori){
  46.         ui->lineUsername->clear();
  47.         ui->linePassword->clear();
  48.         logged=false;
  49.     }
  50.     //try to read data from vector
  51.  
  52.     try {
  53.         scriviProfilo(logged); //try to complete the label of frame linkedin with database information
  54.     } catch (errori) {}
  55.

  102. }
