Newbie question about widgets

[santiagorf]

Hi all,
Using the designer in Qt creator, I have created a widget with a QPushButton object on it called "pushButton", but I have two problems:

1. How to access the objects pushButton
2. How to add another object to the widget from the source code

My code is the following

main.cpp
@
#include <QApplication>
#include "widget.h"

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
Widget w;
w.show();

return a.exec();

}
@

widget.h
@
#ifndef WIDGET_H
#define WIDGET_H

#include <QWidget>
#include <QLabel>

namespace Ui {
class Widget;
}

class Widget : public QLabel
{
Q_OBJECT

public:
explicit Widget(QWidget *parent = 0);
~Widget();
QLabel * label;

private:
Ui::Widget *ui;
};

#endif // WIDGET_H
@

There is another file widget.ui that is the form with the QPushButton, and the file
widget.cpp

@
#include "widget.h"
#include "ui_widget.h"

Widget::Widget(QWidget *parent) : QLabel (parent), ui(new Ui::Widget){
// label =new QLabel("aaaaaaaaaa");
//ui->pushButton->setText("test");
ui->setupUi(this);
}

Widget::~Widget()
{
delete ui;
}
@

where I have the two problems.

1)In the first comment, I try to add a new label

2)In the second comment, I try to change the text on the pushButton

Neither of them seem to be the right approach.
Any help would be much appreciated!

bq. In the first comment, I try to add a new label

Label will be created by qmake generated code. Don't worry about it.

bq. In the second comment, I try to change the text on the pushButton

Do it after setupUI call.

thanks for the prompt reply. I

I changed it to this; now I'm able to change the pushButton, but I still don't know how to add/display the label in the widget.

@
Widget::Widget(QWidget *parent) : QLabel (parent), ui(new Ui::Widget){
ui->setupUi(this);
ui->pushButton->setText("test");
label =new QLabel("aaaaaaaaaa");

}

Open the ui file in qtcreator, drop a qlabel in the ui file.
In the cpp file, @ui->label->setText("aaaaa");@
You can add QLabel from code too, but I feel you might want to play around with adding items in widget.ui file at the moment. Also after compilation and linking, open the generated file ui_widget.h and see what all code is being generated for you.

I got the idea of adding items with widget.ui, and I also have been able to create create dialogues from code.
However, I'd like to know how to add widgets from code into a form created using graphic tools.
