QT 5 QTreeWidgetItem setData()
-
Currently, i am have a QTreeWidget setup, and it is displaying information properly. Now i am trying to interact with it. When a user clicks on a node of the treeWidget, i need to pass a custom data object thru so i can act accordingly.
in Editor.h i have the following
#include <QtWidgets/QMainWindow>
#include <QtCore/QVariant>
#include <QMetaType>
...
const int ITEM_NONE = 0;
const int ITEM_NODE = 1;
const int ITEM_COMPONENT = 2;
const int NO_ITEM = 0xFFFFFFFF;class SceneItem {
public:
SceneItem() { type_ = 0; id_ = 0; }
SceneItem(unsigned type, unsigned id) { type_ = type; id_ = id; }
SceneItem(SceneItem* sceneItem) { type_ = sceneItem->type_; id_ = sceneItem->id_; }
~SceneItem() { }public:
unsigned int type_;
unsigned int id_;
};Q_DECLARE_METATYPE(SceneItem*);
...
};then inside of Editor.cpp i have the following
void OnLoad() {
...
SceneItem sceneItem;
sceneItem.id_ = 1;// scene_->GetID();
sceneItem.type_ = 1;// ITEM_NODE;QVariant sceneItemVariant = qVariantFromValue(&sceneItem);
item->setData(0, Qt::UserRole, sceneItemVariant);
ui.sceneTreeWidget->addTopLevelItem(item);
...
}i then have a signal setup for itemClicked to pass thru the QTreeWidgetItem, and this works.
then i try and extract the data as follows
void Editor::OnSceneTreeItemSelected(QTreeWidgetItem* item, int i) {
QVariant sceneItemVariant = item->data(0, Qt::UserRole);
SceneItem* sceneItem = sceneItemVariant.value<SceneItem*>();
UpdateSceneAttributes(sceneItem);
}when i extract the data, sceneItem has the values of
id_ = 75661952
type_ = 0Any suggestions of help would be much appreciated!
