[merry]

Hi all

i am new in QT3.1 on Linux red hat
and i have a problem with QListView
i have a main window on that i have file menu futher having open (item)
when i select open then it show a file dialog from where i can select a path
now i want that what ever i select the path that path should come out in a tree structure(in hierarchy ) like first folder is root , subfolder,sub sub folder,filesetc



please do help me for this problem
thanks in advance

Well,

Is it not already the case ?
I don't remember well with Qt3, but it seems a file dialog returns you the absolute path...
Do you have an example ?

How about:

QListView lv;
QString path;
QStringList slist = QStringList::split("/", path);
QListViewItem *item = 0;
while(!slist.empty()){
  QString elem = slist.front();
  slist.pop_front();
  if(!item){
    item = new QListViewItem(&lv);
  } else {
    item = new QListViewItem(item);
  }
  item->setText(elem);
}

QListView lv;
QString path;
QStringList slist = QStringList::split("/", path);
QListViewItem *item = 0;
while(!slist.empty()){
  QString elem = slist.front();
  slist.pop_front();
  if(!item){
    item = new QListViewItem(&lv);
  } else {
    item = new QListViewItem(item);
  }
  item->setText(elem);
}

In this it displays the selected path in the form of tree but i want to display all the files and folders of the last item of the selected path that is last item of the selected path is root and it displays all the files and folders contained in the root item.


Foreg.

the selected path is /home/qt/etc

here in the selected path "etc" should be the root item and it displays all the files and folders contained in the "etc" in the the form of the tree structure.

Please reply me as soon as possible its really very very urgent

Thanx

And the problem is...?

QDir::entryList() or QDir::entryInfoList() will give you a list of entries in a particular directory. Just wrap the result into QListViewItems and you're done.

Please reply me as soon as possible its really very very urgent

Please don't say that, it won't make anyone answer your post faster than without it...

Thanx 4 the reply

But it be better if You explain it with me the help of an example or code.

[wysota]

Oh come on, what is there to explain?

QStringList slist = QDir("/etc/").entryList();
for(QStringListIterator it = slist.begin(); it!=slist.end(); ++it){
  new QListViewItem(*it, listview);
}

QStringList slist = QDir("/etc/").entryList();
for(QStringListIterator it = slist.begin(); it!=slist.end(); ++it){
  new QListViewItem(*it, listview);
}

If there is some alterations in this code then also tell me.

Thanx

[wysota]

Why don't you debug the code and see where it segfaults? This is only a snippet, so I can't debug it for you. Please use a debugger and print a backtrace to see where and why it crashes.

[merry]

Thanx 4 ur reply and I also dont want YOU to debug for me.

Once again Thanx

Make sure you initialize all of the variables you use in Form1::setDir().
