I have created a class horrizontalprogressbar in which i created a simple progressbar. I have another class called mainwindow and I would like to access and display the contents of horrizontalprogressbar on mainwindow. I tried a lot off things here, but still I keep getting the horrizontalprogressbar and mainwindow on separate windows. Is there anyway to display them both on the same same window. Since I am new to QT, I would much appreciate any help I could get to resolve this.
Please find the code below:- horrizontalprogressbar.h
#ifndef HORRIZONTALPROGRESSBAR_H
#define HORRIZONTALPROGRESSBAR_H
#include <QProgressBar>
#include <QWidget>
class horrizontalprogressbar: public QProgressBar
{
Q_OBJECT
public:
horrizontalprogressbar();
QProgressBar progressBar_horizontal;
};
#endif // HORRIZONTALPROGRESSBAR_H
horrizontalprogressbar.cpp
#include "horrizontalprogressbar.h"
horrizontalprogressbar::horrizontalprogressbar()
{
progressBar_horizontal.setRange(0,5);
progressBar_horizontal.setValue(2.5);
progressBar_horizontal.setFixedSize(300,50);
//progressBar_horizontal.show();
}
mainwindow.h
#ifndef MAINWINDOW_H
#define MAINWINDOW_H
#include <QMainWindow>
#include <QtWidgets>
class horrizontalprogressbar;
class MainWindow : public QMainWindow
{
Q_OBJECT
private:
horrizontalprogressbar *progressbar_H;
public:
MainWindow();//(QWidget *parent = 0);
~MainWindow();
};
#endif // MAINWINDOW_H
mainwindow.cpp
#include "mainwindow.h"
#include "horrizontalprogressbar.h"
MainWindow::MainWindow()//(QWidget *parent)
// : QMainWindow(parent)
{
progressbar_H = new horrizontalprogressbar;
setCentralWidget(progressbar_H);
progressbar_H->setParent(this);
//progressbar_H->setFixedSize(200,200);
//progressbar_H->show();
}
MainWindow::~MainWindow()
{
}
main.cpp
#include "mainwindow.h"
#include <QApplication>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.setFixedSize(800,600);
w.setStyleSheet("QMainWindow {background: 'black';}");
w.show();
return a.exec();
}
