QList problem

[scarecr0w132]

Hello,

I want to make a QList like this

makeSphere
    center
    radius
 
makeBox
    width
    length
    height

makeSphere
    center
    radius

makeBox
    width
    length
    height

To copy to clipboard, switch view to plain text mode 

How can I do this?

Thank you!

Use QTreeWidget / QTreeView

Hi,

I am processing a large amount of data.
Is QTreeWidget / QTreeView the best solution for this?

Thanks

What do you mean with "make a QList like this"?

Do you want to display data like this? Then use a QTreeView.
What is the data source (a QList has no parents/childs)?

Hi Infinity,

I don't want to display.
I want to store data in something like a QList that has a parent(QString) and children(QString)

Thanks

You can construct your own data structure however you want using the facilities offered by C++ and Qt. How you do it depends on exactly what the requirement is and how you have to manipulate the data.

One possibility for the problem as posted is:

struct Entry {
  Entry(const QString &n, const QStringList &c = QStringList()):
    name(n), children(c)
  { }
  QString name;
  QStringList children;
};
QList<Entry> mySingleLevelHeirarchy;

struct Entry {
  Entry(const QString &n, const QStringList &c = QStringList()):
    name(n), children(c)
  { }
  QString name;
  QStringList children;
};
QList<Entry> mySingleLevelHeirarchy;

To copy to clipboard, switch view to plain text mode 

If the structure needs to be arbitrarily deep

struct Entry {
  Entry(const QString &n, const QList<Entry> &c = QList<Entry>()):
    name(n), children(c)
  { }
  QString name;
  QList<Entry> children;
};
QList<Entry> myMultiLevelHeirarchy;

struct Entry {
  Entry(const QString &n, const QList<Entry> &c = QList<Entry>()):
    name(n), children(c)
  { }
  QString name;
  QList<Entry> children;
};
QList<Entry> myMultiLevelHeirarchy;

To copy to clipboard, switch view to plain text mode 

You could even use QStandardItemModel if you really wanted to.
