mousePressEvent do not work

[dexli]

Hi all,

I fail to get the mousePressEvent working for QDateEdit.

If the right button is clicked a menue shows up. Is there a way to setup my one menue for this ? (add items at least)

Thanks

If you want to do something with the right click you should subclass the contextMenuEvent(QContextMenuEvent *event)

Mywidget.h

#ifndef MYWIDGET_H
#define MYWIDGET_H
 
#include <QtGui>
class QAction;
 
class MyWidget : public QDateEdit
 
{
    Q_OBJECT
public:
    explicit MyWidget(QWidget *parent = 0);
protected:
    virtual void contextMenuEvent(QContextMenuEvent *event);
public slots:
private:
    QAction *actionNew;
 
};
 
#endif // MYWIDGET_H

#ifndef MYWIDGET_H
#define MYWIDGET_H

#include <QtGui>
class QAction;

class MyWidget : public QDateEdit

{
    Q_OBJECT
public:
    explicit MyWidget(QWidget *parent = 0);
protected:
    virtual void contextMenuEvent(QContextMenuEvent *event);
public slots:
private:
    QAction *actionNew;

};

#endif // MYWIDGET_H

To copy to clipboard, switch view to plain text mode 

MyWidget.cpp

#include <QMessageBox>
#include <QAction>
#include "mywidget.h"
 
 MyWidget::MyWidget(QWidget *parent ):
       QDateEdit(parent)
{
   setDate(QDate(1977,2,15));
   actionNew = new QAction(tr("Do Something New"), this);
   actionNew->setShortcuts(QKeySequence::New);
//   connect(actionNew, SIGNAL(triggered()), this, SLOT(DoSomethingNew()));
}
 
 void MyWidget::contextMenuEvent(QContextMenuEvent *event)
{
    QMenu menuRight(this);
    menuRight.addAction(actionNew);
 
    menuRight.exec(event->globalPos());
}

#include <QMessageBox>
#include <QAction>
#include "mywidget.h"

 MyWidget::MyWidget(QWidget *parent ):
       QDateEdit(parent)
{
   setDate(QDate(1977,2,15));
   actionNew = new QAction(tr("Do Something New"), this);
   actionNew->setShortcuts(QKeySequence::New);
//   connect(actionNew, SIGNAL(triggered()), this, SLOT(DoSomethingNew()));
}

 void MyWidget::contextMenuEvent(QContextMenuEvent *event)
{
    QMenu menuRight(this);
    menuRight.addAction(actionNew);

    menuRight.exec(event->globalPos());
}

NOTE: this code replaces the default context menu

Hi Rhayader, hi rest

thanks for this hint.
In the meantime i found out why the mouseevents do not work as i expected.
Actually they work but not for the edit field (QlineEdit) they work for the QSpinBox.
If one click on the arrow the are called.


Two additional questions :
1. How to overwrite the QLineEdit mouseevent methods.
2. How can I access the 'original' menue to add the action there instead of creatin a new menu.

Thanks and have fun
Dexli
