    In my qt C++ application I create buttons dynamically based on a qstringlist I received! when I click the buttons I want to open an interface(dialo2.ui) and send another QStringList(based on that button that I click) to that interface via signals and slots.

    In the newly created interface the contents of the qstringlIst sent is displayed in labels!

    following is my code.

    Dialog.h

    #ifndef DIALOG_H
    #define DIALOG_H
    #include "QFrame"
    #include "QLabel"
    #include "QLineEdit"
    #include "QPushButton"
    #include "dialog2.h"
    
    #include <QDialog>
    
    namespace Ui {
    class Dialog;
    }
    
    class Dialog : public QDialog
    {
    Q_OBJECT
    
    public:
    Dialog2 dialog2;
    QFrame *f1;
    QPushButton *a;
    QList<QStringList> subMessageFields;
    QStringList buttonNames;
    explicit Dialog(QWidget *parent = 0);
    QStringList subMessages;
    QStringList Messages1;
    

    QStringList Messages2;

    ~Dialog();

    private slots:
    void on_pushButton_clicked();
    void receiveSubMessages(QStringList List);
    void openWindow();
    void getButtons();
    

    Dialog.cpp

    #include "dialog.h"
    #include "ui_dialog.h"
    #include "QFrame"
    #include "QLabel"
    #include "QLineEdit"
    #include "dialog2.h"
    
    Dialog::Dialog(QWidget *parent) :
    QDialog(parent),
    subMessages{"0"},
    
    ui(new Ui::Dialog)
    {
    ui->setupUi(this);
    
    }
    
    Dialog::~Dialog()
    {
    delete ui;
    }
    
    void Dialog::receiveSubMessages(QStringList List){
    
    subMessages=List;
    ui->comboBox->addItems(subMessages);
    
    for(int i=0;i<subMessages.size();i++){
        QString Name= QString::number(i);
        f1 = new QFrame();
        a= new QPushButton();
        a->setText(subMessages[i]);
        a->setObjectName("Button"+Name);
    
        ui->horizontalLayout->addWidget(a);
    
     //
    
    }
    getButtons();
    }
    
    void Dialog::getButtons(){
    
    Messages1<<"John"<<"Smith";
    Messages2<<"Hello"<<"Anne";
    
    for(int i=0;i<subMessages.size();i++){
           QPushButton *le = findChild<QPushButton*>(QString("Button%1").arg(i));
    if((le)&&(i==0)){
    connect(le, SIGNAL(clicked()), this, SLOT(openWindow()));
    connect(this,SIGNAL(sendList(QStringList)),&dialog2,SLOT(receiveList(QStringList)));
    emit sendList(Messages1);
    
             }
           else if((le)&&(i==1)){
                if(connect(le, SIGNAL(clicked()), this, SLOT(openWindow()))){
                connect(this,SIGNAL(sendList(QStringList)),&dialog2,SLOT(receiveList(QStringList)));
                 emit sendList(Messages2);
            }
    
             }
        
             }
    void Dialog::openWindow(){
    dialog2.exec();
    }
    

    Dialog2.h

    #include <QDialog>
    #include "QFrame"
    #include "QLabel"
    #include "QLineEdit"
    
    namespace Ui {
    class Dialog2;
    }
    
    class Dialog2 : public QDialog
    {
    Q_OBJECT
    
    public:
    QFrame *f1;
    QFrame *f2;
    QLabel *label;
    QLineEdit *text;
    QStringList subMessageList;
    explicit Dialog2(QWidget *parent = 0);
    ~Dialog2();
    
    private slots:
    void on_pushButton_clicked();
    void receiveList(QStringList List);
    
     void on_pushButton_2_clicked();
    

    Dialog2.cpp

    #include "dialog2.h"
    #include "ui_dialog2.h"
    
    Dialog2::Dialog2(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::Dialog2)
    {
    ui->setupUi(this);
    }
    
    Dialog2::~Dialog2()
    {
    delete ui;
    }
    
    void Dialog2::on_pushButton_clicked()
    {
    ui->label->setText(QString::number(subMessageList.size()));
    }
    
    void Dialog2::receiveList(QStringList List){
    subMessageList=List;
    for(int i=0;i<subMessageList.size();i++){
    //create dynamic widgets
    f1 = new QFrame();
    
    text= new QLineEdit(f2);
    label = new QLabel(f1);
    ui->verticalLayout->addWidget(f1);
            ui->verticalLayout_2->addWidget(f2);
    label->setText(subMessageList[i]);
    }
    }
    

    Here I have supported 2 buttons dynamically created( i=0 and i=1)
    But when I click the button which resembles i=0 I get the labels Hello, Anne , John, Smith ,John, Smith! I want only to see Hello Anne in the labels since that button only emits Messages1 qstringList! How can I achieve this?

      @Kushan said in sending QStringLists from dynamically created buttons using signals and slots:

      for(int i=0;i<subMessageList.size();i++){

      Well, you're adding the complete list. If you only want to add part of it then do so.

        @jsulm yeah but! If I click the first button ( i.e i==0). The dialog2.ui which opens up should only show "John" and "Smith" in the labels right? because I only emit QStringList "Message1"! but when I click that button both contents of Message1 and Message2 QStringLists are shown in the labels of dialog2.ui!

          Hi
          Check what you actually sets. I does seems its only one text but hard to tell

          void Dialog2::receiveList(QStringList List) {
            subMessageList = List;
            for(int i = 0; i < subMessageList.size(); i++) {
              //create dynamic widgets
              f1 = new QFrame();
              text = new QLineEdit(f2);
              label = new QLabel(f1);
              ui->verticalLayout->addWidget(f1);
              ui->verticalLayout_2->addWidget(f2);
              QString text=subMessageList[i];
              qDebug() << "text is" << text;
              label->setText(text);
            }
          }

                      @mrjj yeah but how can I change my code so that only
                      text is "John"
                      text is "Smith"

                      @Kushan

                      You seems to connect multiple times to same dialog2

                      for(int i=0;i<subMessages.size();i++){
                      ....
                      connect(this,SIGNAL(sendList(QStringList)),&dialog2,SLOT(receiveList(QStringList)));

                      When you then call emit it will call that many times, so i think you mean just to call once
                      out side the loop.


                      connect(this,SIGNAL(sendList(QStringList)),&dialog2,SLOT(receiveList(QStringList)));
                      for(int i=0;i<subMessages.size();i++){
                      .....

                        @mrjj yeah thanx but the problem is if I place it outside then I can't connect the signal to a particular button right? Here I connect the signal using the value of i in the for loop

                          Only for the dialog2 as you dont create new dialog2 and hence get multiple
                          connect to same.

                          for the LE button , inside loop is correct. ( as you find new one to connect to )

                          So only call
                          connect(this,SIGNAL(sendList(QStringList)),&dialog2,SLOT(receiveList(QStringList)));
                          ONCE or it will send many times to same dialog.

                            @mrjj Thanx alot! now it is 80% working! But the only problem I face now is when I click the 1st button close the dialog2.ui which pops up and click the second button and open dialog2.ui it is like

                            text is "John"
                            text is "Smith"
                            text is "Hello"
                            text is "Anne"

                            How can I remove the following part?
                            text is "John"
                            text is "Smith"

                              If you reuse same dialog2 for button1 AND button2, it will still have the Labels from last time.
                              I think most easy would be to delete it and create it again.
                              (its not super easy to clear a layout)

                              I assume its this one ?
                              Dialog2 dialog2;

                              its a bit hard to delete as its not pointer.

                              you could use

                              void clearLayout(QLayout *layout) 
                              {
                                  if (layout) {
                                      while(layout->count() > 0){
                                          QLayoutItem *item = layout->takeAt(0);
                                          QWidget* widget = item->widget();
                                          if(widget)
                                              delete widget;
                                          delete item;
                                      }
                                  }
                              }
                              

                              void Dialog2::receiveList(QStringList List){
                              clearLayout(ui->verticalLayout);
                              ....

                              So each time you call Dialog2::receiveList it removes what it has and then add the new stuff.

                                  What you mean delete dialog2.ui ? ( ui files are like cpp/.h files)

                                  is it not the variable in Dialog called Dialog2 dialog2 u are using ?

                                    @mrjj Thanx alot it works fine! I am also interested in using pointers!

                                    if I had used Dialog2 *dialog2 = new Dialog2(); instead of Dialog Dialog2 what should I do without using the clearLayout method?

                                      @Kushan
                                      just
                                      delete dialog2;
                                      dialog2->deletelater();
                                      (that also delete all you put into it)

                                      And BEFORE using it again
                                      dialog2 = new Dialog2(); // new it again

                                      Note:
                                      Qt has a auto delete system. So any parent will delete its children so
                                      dont delete a button u have given to a layout.
                                      http://doc.qt.io/qt-5/objecttrees.html
                                      It works here as you dont give the dialog a parent.

                                      if you did
                                      Dialog2 *dialog2 = new Dialog2(this); "this" would own it and
                                      it would be bad to delete it manually as when ever "this" is deleted it would
                                      try to delete dialog. ( a second time)

                                      update
                                      Also
                                      you can use
                                      setAttribute(Qt::WA_DeleteOnClose);
                                      which will auto delete dialog when you press close/ok/cancel
                                      and in that case , you must new it before use each time and it will
                                      delete itself

                                        In the case mentioned by @mrjj , use deleteLater.
