To much space between spinner label and label in custom list widget.

[Krpadia123]

I am trying to add loading spinner and some text besides it in custom list widget, but somehow I can see lot of space between them, I tried various alignment but none worked.
Please follow below image.

Code:

1. main.cpp

#include "mainwindow.h"
#include <QApplication>
#include <QHBoxLayout>
#include <unistd.h>
#include <QMovie>

QCustomListWidgetItem::QCustomListWidgetItem(std::string labelText, QWidget* parent)
: QWidget(parent), m_pJobName(labelText)
{
    setup();
    layout();
}

void QCustomListWidgetItem::setup()
{
    m_pItemLabel = new QLabel(QString::fromStdString(m_pJobName), this);
    m_pItemLabel->setObjectName("messageLabel");
    m_pSpinnnerLabel = new QLabel(this);
    QMovie* movie =
        new QMovie(QString::fromStdString("D:/temp/loadingSpinner.gif"), QByteArray(), this);

    movie->setScaledSize(QSize(25, 25));
    m_pSpinnnerLabel->setMovie(movie);
    m_pSpinnnerLabel->show();
    movie->start();
}

void QCustomListWidgetItem::layout()
{
    QHBoxLayout* listWidgetLayout = new QHBoxLayout(this);
    listWidgetLayout->setContentsMargins(0, 0, 0, 0);
    listWidgetLayout->setSpacing(0);
    listWidgetLayout->addWidget(m_pSpinnnerLabel, 0, Qt::AlignLeft);
    listWidgetLayout->addWidget(m_pItemLabel, 0, Qt::AlignLeft);
    setLayout(listWidgetLayout);
    setFixedHeight(25);
}

UploadJobListDialog::UploadJobListDialog(std::vector<std::string> jobNames, QWidget* parent)
    : QDialog(parent) , m_pJobNames(jobNames)
{
    addListWidgetItems();
}

void UploadJobListDialog::addListWidgetItems()
{
    m_pListWidget = new QListWidget(this);
    QString listStyle(
        "QListWidget::item:hover,"
        "QListWidget::item:disabled:hover,"
        "QListWidget::item:hover:!active,"
        "{background:#FFFFFF;}");

    m_pListWidget->setStyleSheet(listStyle);
    m_pListWidget->setFixedSize(QSize(470, 150));

    for (const auto& jobName: m_pJobNames)
    {
        QListWidgetItem* listWidgetItem = new QListWidgetItem(m_pListWidget);
        QCustomListWidgetItem* customListWidget = new QCustomListWidgetItem(jobName,m_pListWidget);
        listWidgetItem->setSizeHint(customListWidget->size());
        listWidgetItem->setFlags(listWidgetItem->flags() & ~Qt::ItemIsSelectable);
        m_pListWidget->addItem(listWidgetItem);
        m_pListWidget->setItemWidget(listWidgetItem, customListWidget);
    }
}


int main(int argc, char *argv[])
{
   QApplication a(argc, argv);
   std::vector<std::string> jobs;
   for(int i = 0; i < 5; i++)
   {
       jobs.push_back(std::to_string(i));
   }

   UploadJobListDialog obj(jobs);
   obj.exec();
   return 0;
}

2. mainwindow.h

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
#include <QtWidgets/QDialog>
#include <QtWidgets/QListWidget>
#include <QLabel>
#include <QObject>


QT_BEGIN_NAMESPACE
namespace Ui { class MainWindow; }
QT_END_NAMESPACE

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    MainWindow(QWidget *parent = nullptr);
    ~MainWindow();

private:
    Ui::MainWindow *ui;
};
#endif // MAINWINDOW_H


//Custom WidgetItem
class UploadJobListDialog : public QDialog
{
    Q_OBJECT
public:
    explicit UploadJobListDialog(std::vector<std::string> jobNames, QWidget* parent = NULL);

private:
    void addListWidgetItems();
    QListWidget* m_pListWidget = nullptr;

    std::vector<std::string> m_pJobNames = {};

};

class QCustomListWidgetItem : public QWidget
{
    Q_OBJECT
    public:
        explicit QCustomListWidgetItem(std::string labelText, QWidget* parent = NULL);
    void setup();
    void layout();

    private:

        QLabel* m_pItemLabel = nullptr;
        QLabel* m_pSpinnnerLabel = nullptr;
        std::string m_pJobName;
};

Why I am getting this large space in between, am I doing something horrible?

I am new to QT, any help is very much appreciated.

Hi @Krpadia123, try adding a stretch with a factor of 1 for your label so it takes the whole space and not only half.

...
listWidgetLayout->addWidget(m_pSpinnnerLabel, 0, Qt::AlignLeft);
listWidgetLayout->addWidget(m_pItemLabel, 1, Qt::AlignLeft);
setLayout(listWidgetLayout);
...

Neat! Thank You!
