Hi,
Could you tell me which is the last step if its not rendering.
By the way i will tell about what i am trying to do here.
I am trying to build a tree .In this tree i have an icon pair which says YES
or NO.
I have collected all iconpair and stored it in a vector. I am using iconpair
stored in vector to change icons being shown.
The part of the codes are
void MTreeList::initialize() // a virtual fucntion of WApplication
{
treeList->setIconsForTreeLeafs(); //treelist is an object of
DemoTreeList
}
void DTreeList::setIconsForTreeLeafs()
{
vector<TreeNodeCapacity >::const_iterator treeList;
for(treeList = Treeility.begin(); treeCapsList
!=TreeCapability.end();treeCapsList++)
{
Wt::WIconPair *icon = (treeList->node)->labelIcon();
if(treeList->capacity == 0)
icon->showIcon1();
else
icon->showIcon2();
}
}
I also tried to evocate function setIconsForTreeLeafs() using two type of
events
(tree_->expanded()).connect(SLOT(this, DTreeList::setIconsForTreeLeafs));
or
(icon->icon1Clicked()).connect(SLOT(this,
DTreeList::setIconsForTreeLeafs));
In both cases i get to know that user try to expand tree.
Signal tree_->expanded notify me about user trying to expand tree .
Signal icon->icon1Clicked notify that user is trying to expand by clicking
on icon on tree. Icon is the iconpair of root tree.
Unfortunately in all the three case it results in a crash.
