Add textEdits on listWidget

jsulm · 25 Jun 2018, 04:34

@Kinesis Why do you want to add text edit to a list widget? You should use a doc.qt.io/qt-5/qvboxlayout.html instead of a QListWidget.

Because I am trying to display image icons,videos and textedits on listwidget which is a layout . Now I can display images on listwidget . I need to show textedits.Thats why.BTW that's for my own application project.Thanks

@Kinesis QListWidget isn't a layout, it is a widget. I don't think you can add text edit easily to QListWidget, maybe you can if you subclass QListWidgetItem. Does it really need to be text edit (I guess you mean QLineEdit?)? Or is it only read-only text?

@jsulm
For QLineEdit , I tested it . I found that it is not suitable because QLineEdit is 1 line text editor . I need to show text with multiple lines .And the text should be read-only text. That's why text edit or text browse is the most suitable for me.
So is there another widget that textedits can be added ??

@Kinesis If the text is read-only why not simply add it using http://doc.qt.io/qt-5/qlistwidgetitem.html#QListWidgetItem-2 ?

QListWidgetItem *item = new QListWidgetItem(icon, "some text");
listWidget->addItem(item);

@jsulm
read-only text means text inside textedit is read only.plz take alook my code and u will understand clearly.

for(const QFileInfo & finfo: directory.entryInfoList()){
    m_textEdit = new QTextEdit;
    QFile data(finfo.absoluteFilePath()) ;
    data.open(QIODevice::ReadOnly);
    QTextStream stream(&data);
    QString content = stream.readAll();
    data.close();
    
    
    m_textEdit->setText(content);
    m_textEdit->show();
    ui->listWidget->addItem(m_textEdit);
}

The problem is that I cant add textEdit on listWidget easily .

@Kinesis Sorry, but I still don't get why you need a QTextEdit? QListWidgetItem already can show text:

for(const QFileInfo & finfo: directory.entryInfoList()){
    QFile data(finfo.absoluteFilePath()) ;
    data.open(QIODevice::ReadOnly);
    QTextStream stream(&data);
    QString content = stream.readAll();
    data.close();
    
    QListWidgetItem *m_textEdit = new QListWidgetItem(content);
    ui->listWidget->addItem(m_textEdit);
}

@jsulm
Thanks for your code but I want to show textedits on list widget like that image
BTW I really appreciate your help :)

jsulm · 25 Jun 2018, 06:26

@Kinesis But what is wrong with my code? It should show the text inside the QListWidget.
Your picture shows each text in its own window - is this what you want?!

Kinesis · 25 Jun 2018, 06:28

@jsulm
Yes , I want to show text with separate textedit .

jsulm · 25 Jun 2018, 06:42

@Kinesis My question was whether you want to show it in a WINDOW like in your picture.
And can you explain why you need a QTextEdit to show read-only text if you already can show text in QListWidget? I really don't understand that.

@jsulm
Here is my sample GUI that I am planning to create . In this sample U will see that all videos ,images and textedits will be showed on same widget! Thats why I need to use textedit 0_1529908949075_AA.png

@Kinesis

like this(only example):

ui->listWidget->setFlow(QListView::LeftToRight);
ui->listWidget->setGridSize(QSize(110, 90));
ui->listWidget->setResizeMode(QListView::Adjust);
ui->listWidget->setViewMode(QListView::ListMode);
ui->listWidget->setWrapping(true);

for (const QFileInfo &finfo : directory.entryInfoList()) {
    [...]
    auto    item = new QListWidgetItem("", ui->listWidget);
    auto    text = new QTextEdit(content);
    text->setMinimumSize(100, 80);
    ui->listWidget->setItemWidget(item, text);
}
