Hi
I have created an app , where I click a node of a tree, it would open a website.
my problem is that , it should work only for a particular node, but currently it works for every node.
the code for creating the tree is

Qt Code: 
  1. //creates a child of a root
  2. QTreeWidgetItem* SettingsTree::createItem(const QString &text, QTreeWidgetItem *parent, int index)
  3. {
  4.     QTreeWidgetItem *after = 0;
  5.     if (index != 0)
  6.         after = childAt(parent, index - 1);
  7.  
  8.     if (parent)
  9.         item = new QTreeWidgetItem(parent, after);
  10.     else
  11.         item = new QTreeWidgetItem(this, after);
  12.  
  13.     item->setText(0, text);
  14.     return item;
  15. }
  16.  
  17.  
  18. //finds the child at particular index
  19. QTreeWidgetItem *SettingsTree::childAt(QTreeWidgetItem *parent, int index)
  20. {
  21.     if (parent)
  22.         return parent->child(index);
  23.     else
  24.         return topLevelItem(index);
  25. }
  26. //tree 1 created
  27. QTreeWidgetItem* SettingsTree::eBeamTREE()
  28. {
  29.  
  30.     root->setText(0,"EBEAM GALLERY");
  31.     for(int i=0;i<1;i++)
  32.     {
  33.  
  34.      createItem("Art & Design",root,0);
  35.      createItem("Classroom Tools",root,1);
  36.      createItem("Dynamic Content",root,2);
  37.      createItem("Geography",root,3);
  38.      createItem("Health",root,4);
  39.      createItem("History & Social Studies",root,5);
  40.      createItem("Literature & Language Arts",root,6);
  41.      createItem("Mathematics",root,7);
  42.      createItem("Music & Theatre",root,8);
  43.      createItem("Recreation & Games",root,9);
  44.      createItem("Science",root,10);
  45.      createItem("Backgrounds",root,11);
  46.      createItem("Tips & Tricks",root,12);
  47.  
  48.     }
  49.      return root;
  50. }
  51.  
  52. //tree 2
  53. QTreeWidgetItem* SettingsTree::eBeamMYGALLERY()
  54. {
  55.  
  56.     root1->setText(0,"MY GALLERY");
  57.     for(int i =0;i<1;i++)
  58.     {
  59.       createItem("My Gallery",root1,0);
  60.     }
  61.     return root1;
  62. }
  63.  
  64.  
  65. //tree3
  66. QTreeWidgetItem* SettingsTree::eBeamRESOURCETREE()
  67. {
  69.     root2->setText(0,"RESOURCES");
  70.     for(int i=0;i<1;i++)
  71.     {
  72.         child = createItem("eBeam Web Resources",root2,0);
  73.  
  74.     }
  75.     root2->setFlags(Qt::ItemIsSelectable);
  76.     return child;
  77. }
