Newbie dealing with statusbar incluiding widgets.

[chavetaz]

Hi,
Im newbie in QT and C++...
Im trying to add widgets (label and progressbar) to statusbar and found 2 ways (I think...):

1- create the widgets and add them to statusbar in main class. this works OK!! but I dont know how to update the progressbar within mainwindow class... I stopped here... :confused::confused:

2- I see in this forum: create the widgets and add them to statusbar in mainwindow class (maybe is more simple to access to update values) but i doesnt work... I stopped here.... :confused::confused:

Anyone please assist me?

I post the code of my second option (may be the best???):

Mainwindow.h :


#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
#include <QUrl>
#include <QMap>
#include <QProgressBar>
#include <QHBoxLayout>
#include <QLabel>


namespace Ui {
class MainWindow;
}

class MainWindow : public QMainWindow
{
Q_OBJECT

public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();

private:
void init();
void createStatusBar();

Ui::MainWindow *ui;
QMap<QString, int> Globales;
// QFrame status_frame;
// QHBoxLayout layout;
QProgressBar *bar;
QLabel *box;

private slots:
void on_Web_loadProgress(int progress);
void on_Web_urlChanged(QUrl);
void on_Web_loadStarted();
void on_BtnLogin_toggled(bool checked);
};

#endif // MAINWINDOW_H


mainwindow.cpp :


#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QWebSettings>
#include <QProgressBar>
#include <QLabel>
#include <QStatusBar>
#include <QProgressBar>


MainWindow::MainWindow(QWidget *parent): QMainWindow(parent), ui(new Ui::MainWindow)
{
// Rutinas de Inicio
createStatusBar();
init();

ui->setupUi(this);

}

MainWindow::~MainWindow()
{
delete ui;
}

void MainWindow::on_BtnLogin_toggled(bool checked)
{
if (checked) {
//login
Globales["Estado"] = 0;
ui->Web->load(QUrl(ui->txtURL->text()));
}
else{
//logout.
ui->Web->load(QUrl("http://..."));
Globales["Estado"] = 0;
}
}

void MainWindow::on_Web_loadStarted()
{
// here I intent to show the progressbar
//ui->statusBar->pBar->show();
}

void MainWindow::on_Web_urlChanged(QUrl newurl)
{
ui->LogNav->setTextColor(QColor("blue"));
ui->LogNav->append(newurl.toString());
}

void MainWindow::init()
{
//Fijar seteos del browser
QWebSettings::globalSettings()->setAttribute(QWebSettings::AutoLoadImages, false);

}

void MainWindow::on_Web_loadProgress(int progress)
{
// Here I intent to update the progressbar
}

void MainWindow::createStatusBar()
{
// status_frame = new QFrame();
// status_frame->setFrameStyle(QFrame::Panel | QFrame::Sunken);

// layout = new QHBoxLayout(status_frame);
// layout->setContentsMargins(0, 0, 0, 0);

bar = new QProgressBar();
bar->setMaximumHeight(10);
bar->setMaximumWidth(100);
bar->setValue(80); //for testing

box = new QLabel("Check Mode");

// Two Options: Which is right ???
//ui->statusBar->addWidget(bar);
//ui->statusBar->addWidget(box);
statusBar()->addWidget(bar);
statusBar()->addWidget(box);
}


Best regards!!!

Hi, maybe it already helps to move setupUi() to be the first command in constructor of MainWindow.

PS: statusBar()-method should be Ok in createStatusBar(), in your pasted code the other method should not work or even crash because ui is not set up when you call createStatusBar()
