Adding layout to Qdialog changes the layout in an other Qdialog

gabor53

Hi,
I have 2 QDialogs: Additem and Review.

//Add buttons
           ReviewButton = new QPushButton(tr("&Review"));

           ReviewButton->setStyleSheet ("QPushButton{"
                                        "background-color: rgb(0, 255, 0);"
                                        "border-style: outset;"
                                        "border-width: 2px;"
                                        "border-radius: 10px;"
                                        "border-color: beige;"
                                        "font: bold 14px;"
                                        "min-width: 10em;"
                                        "padding: 6px;}"
                                        );
        ReviewButton->setToolTip ("<b><font size='12'><font color = 'blue'>Click to review your entries.</font></b>");
		ReviewButton->setFixedWidth (100);


        connect(ReviewButton,SIGNAL(clicked(bool)),this,SLOT(review()));

        reset_Button = new QPushButton(tr("&Reset"));

        reset_Button->setStyleSheet ("QPushButton{"
                                        "background-color: rgb(255, 0, 0);"
                                        "border-style: outset;"

                                        "border-radius: 10px;"
                                        "border-color: beige;"
                                        "font: bold 14px;"
                                        "min-width: 10em;"
                                        "padding: 6px;}"
                                        );

        reset_Button->setToolTip ("<b><font size='12'><font color = 'blue'>Click to reset all the fields. This will close the window and clear all your entries.</font></b>");
		reset_Button->setMaximumWidth (100);
        button_Layout->addWidget (ReviewButton);
        button_Layout->addWidget (reset_Button);

        connect (reset_Button,SIGNAL(clicked(bool)),this,SLOT(resetAll()));

//Add title

        QLabel* title = new QLabel;
        title->setText("Add a Friend To the Database");
        title->setAlignment(Qt::AlignCenter);
        QFont f( "Arial", 18, QFont::Bold);
        title->setFont(f);

//Add layout

        titleLayout->addWidget (title);

        scroll->setWidgetResizable (true);
        scroll->setVerticalScrollBarPolicy (Qt::ScrollBarAlwaysOn);
        scroll->setHorizontalScrollBarPolicy (Qt::ScrollBarAlwaysOn);

        grid->setColumnMinimumWidth (1,20);
        grid->setVerticalSpacing (15);
        grid->verticalSpacing ();

        name_Layout->addWidget (LineEdit_Name);
        name_Layout->addWidget (angry_image_Label);
        name_Layout->addWidget (incorrect_Label);
        name_Layout->insertSpacing (1,15);
        name_Layout->insertSpacing (2,15);

        QWidget *viewport = new QWidget(this);
        scroll->setWidget (viewport);
        scroll->setWidgetResizable (true);
        spacer1->setText ("             ");

		grid->addWidget (Label_ID,0,0,1,1,Qt::AlignTop);
        grid->addWidget (ID_Display,0,1,1,1,Qt::AlignTop);
        grid->addWidget (Label_Name,1,0,1,1,Qt::AlignTop);
        grid->addLayout (name_Layout,1,1,1,1,Qt::AlignTop);

        grid->addLayout (button_Layout,3,1,1,1,Qt::AlignCenter);

        scroll->setLayout (grid);


        mainLayout->addLayout (titleLayout);
        mainLayout->addWidget (scroll);

        Additem::setLayout (mainLayout);

}

void Additem::readAndValidate()
{
    name = LineEdit_Name->text ();

    angry_image_Label->setFixedSize (30,30);
    incorrect_Label->setStyleSheet("QLabel { font-size:18px; color: red; }");

                 if(name.length ()<2)
                   {
                      incorrect_Label->setText ("The name is too short!");

                      QPixmap pix("C:/Programming/Projects/Folkfriends/icons/angry.png");

                       angry_image_Label->setScaledContents (true);
                       angry_image_Label->setPixmap (pix);
                   }
                   else
                   {
                       incorrect_Label->setText ("");
                       QPixmap pix2("C:/Programming/Projects/FolkFriends/icons/Check-icon.png");
                       angry_image_Label->setScaledContents (true);
                       angry_image_Label->setPixmap (pix2);
                   }

               qDebug() << " Name in function: " << name;

}

void Additem::review()
{
    revName_Label->setText ("<font size = '12' color = 'blue'>"+name+"</font>");

    Review->setWindowTitle ("Review Friend's Data");

    QFont f( "Arial", 18, QFont::Bold);
    QFont g( "Arial", 16, QFont::Normal);

    rev_Title_Lbl->setFont (f);
    rev_Title_Lbl->setText ("Review the Data You Entered");
    rev_Title->addWidget (rev_Title_Lbl,Qt::AlignHCenter);

    rev_Grid->addLayout (rev_Title,0,0,1,1,Qt::AlignTop);
    rev_Grid->addWidget (Label_ID,2,0,1,1,Qt::AlignTop);
    rev_Grid->addWidget (ID_Display,2,1,1,1,Qt::AlignTop);
    rev_Grid->addWidget (Label_Name,3,0,1,1,Qt::AlignTop);
    rev_Grid->addWidget (revName_Label,3,1,1,1,Qt::AlignTop);

//    Review->setLayout (rev_VLayout);

//    rev_VLayout->addLayout (rev_Grid);

    Review->exec ();
}

void Additem::resetAll()
{
   qDebug()  << "Resetting";
}

When I add

//    Review->setLayout (rev_VLayout);

//    rev_VLayout->addLayout (rev_Grid);

Review displays everything correctly, but Additem changes its layout:
name_Layout moves from position 1,1 to 0,0 and covers up Label_ID.
Please help me figure out why.
Thank you.

Hi,

How are you creating these two layouts ?

@SGaist
Hi,
Using grid layout.

gabor53

Same happens when I use QHBoxLayout in Review which is a QDialog.

SGaist

Can you share the code where you create and setup these two layouts ?

@SGaist
Hi,
Here is the code:
additem.cpp
Thank you for your help.

@gabor53 :

You change the widget geometry in a way it affects hints. so layout has to be updated.
From the top of my head it might be enough to call the following updateGeometry() on every affected widget. Aka:

Actually I take it back.
If you could show your ui->setupUi(this); code I could probably say more, but as for now it seems you are trying to use the same layout in different dialogs. Make sure you do not.
