How to add images to a Listview in QML?

mkhpad

Hi all, i am new to Qml and now i am trying an application in which:when a button is pressed a list of images should be displayed in a QListView.

What i had tried so far is:

I had created a button in .qml file and when clicked on it the function call goes to .cpp file to display the listview with images.
I was able to do it in .qml file itself but i am looking to display it by making a function call to .cpp.

My code:

.qml file

@
Button {
id: button1
x: 79
y: 299
text: "Click here for listview"

    onClicked: {
        Abcd.apple()
    }
}

@

.cpp file:

@
#include"abcd.h"
#include<QListWidgetItem>
#include<QHBoxLayout>
#include<QMainWindow>

void Abcd::apple()
{
QListWidget *listWidget = new QListWidget();
listWidget->setSortingEnabled(true);
listWidget->addItem(new QListWidgetItem(QIcon("c:/apple.jpg")));
listWidget->addItem(new QListWidgetItem(QIcon("c:/ball.jpg")));
listWidget->addItem(new QListWidgetItem(QIcon("c:/cat.jpg")));
listWidget->addItem(new QListWidgetItem(QIcon("c:/dog.jpg")));

    QHBoxLayout *layout = new QHBoxLayout();
    layout->addWidget(listWidget);
    QMainWindow w;
    w.setCentralWidget(listWidget);
    w.showMaximized();

}
@

From my code i was able to get the function call to the .cpp file when tried with some other samples....but when trying to display the image i was not able to do it..

Anyone help me with this so that i can find the solution....

Lots and lots of issues here.

First, format your code nicely, using '@' tags and inserting new line after every or most ';'.

Next, you are mixing QtWidgets and QML, which is not the usual course of things. If you want to add custom functionality to QML, you have to use relevant QDeclarative* classes.

Another thing is, you are creating QMainWindow on a stack, which means that this object will be deleted when the scope ends. in your case, that's the closing bracket ('}').

Also, void Abcd::apple() - is this method a slot, or declared with Q_INVOKABLE? OTherwise, you will not be able to invoke it from QML.
