ListView crash

mititelud

hello,

i am working on a file browser, using a QAbstractListModel. thing is... i can browse through folders, but if one folder is packed with tones of files and folders the qml crashes.

i got this function for browsing folders:
@
void ModelConcrete::downFolder(QString s)
{

m_dir.setFilter(QDir::AllDirs | QDir::Files | QDir::NoDot );    //m_dir is QDir
m_dir.setSorting(QDir::DirsFirst | QDir::Name);
m_dir.setPath(m_dir.path()+"/"+s);

beginResetModel();
m_list.clear();                               //m_list is QList<QFileInfo>
m_list =  m_dir.entryInfoList();
endResetModel();

qDebug()<<"downFolder() was called";

}
@

the listview is pretty basic... i'm printing list items with Component { Item {Rectangle {text and so on... and the Listview {id: delegate: and so on}

Not an answer, but an alternative. Qt has QFileSystemModel:

bq. The QFileSystemModel class provides a data model for the local filesystem.

i am not using qtwidgets, only c++ and qml binding, so i cant use the QFileSystemModel.

it crashes when it loads the names of the sub-folder and sub-files, in the qml.
@
Rectangle
{
width: 800
height: 600
Component
{
id: myDelegate
Item
{
id: itemRoot;
width: 150
height: 30
signal openFile(string fileName);
Rectangle
{
anchors.fill: parent
anchors.margins: 2
radius: 10

            Text
            {
                y:3
                x:20
                id: frstname
                text: name     //sent through the listmodel 
                color: "black"
             }

            MouseArea
            {
               //functions calls like browseFolder() and cdUp()
            }
        }
    }
}

if I change the frstname.text to a static string like "folderName"... i can browse all folders with no problems whatsoever, downside.... all folders are named folderName.
i tried to send the name of the folder through a connect(obj,signal,obj,slot,Qt::QueuedConnection) and directly also, but i only get the crash if a folder has many subfolders or subfiles.

so... QML Text component crashes...but if you use TextEdit or TextInput and use a MouseArea, the TextEdit or TextInput is hacked and it becomes a readonly mode, not writte(a)ble (excuse the english) as expected.

should i mark the thread as [Solved-ish]?
