Qt Context Menu Text Edit Within QTreeWidgetItem

QTAsker

I'm trying to figure out the best way to change the standard context menu of a text edit. For instance, I have a QTreeWidget and when I edit a QTreeItem I am able to change the text data of that QTreeItem. If I right click while editing that text a standard context menu pops up, how do I change this standard context menu of the text edit?

In general I can use,

connect( m_treeWgtItem, SIGNAL( customContextMenuRequested(const & QPoint) ), m_treeWidget, SLOT( OnContextMenu( const & QPoint) );

to set the context menu of the QTreeWidgetItem, but what signal do I use to set the menu of the text edit of said item?

Hi and welcome to devnet,

You can create your own subclass of the editor in order to reimplement contextMenuEvent.

class ContextMenuDelegate : public QStyledItemDelegate {
Q_OBJECT
Q_DISABLE_COPY_MOVE(ContextMenuDelegate)
public:
using QStyledItemDelegate::QStyledItemDelegate;
QWidget *createEditor(QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index) const override{
QWidget* result = QStyledItemDelegate::createEditor(parent,option,index);
if(result){
result->setContextMenuPolicy(Qt::CustomContextMenu);
connect(result,&QWidget::customContextMenuRequested,this,&ContextMenuDelegate::customContextMenuRequested);
}
return result;
}
Q_SIGNALS:
void customContextMenuRequested(const QPoint &pos);
};

To use it:

contextDelegate = new ContextMenuDelegate(this);
treeWidget->setItemDelegate(contextDelegate);
connect(contextDelegate,&ContextMenuDelegate::customContextMenuRequested,this,&MyClass::onContextMenu);

You can create your own subclass of the editor

Valid but you would still need a delegate to create this subclass so might as well just subclass the delegate

@VRonin said in Qt Context Menu Text Edit Within QTreeWidgetItem:

Agreed, I was mainly thinking about keeping the customization together with the editor itself.

Your delegate is quite a good solution :-)
