QComboBox Item Right Click

[wirasto]

How to catch rightclick event on QComboBox item? I tried reimplement mousePressEvent for my custom combobox, but not luck The event just for ComboBox it self, not for Item.

http://doc.qt.digia.com/qt/qcombobox...etItemDelegate implement own QAbstractItemDelegate and implement own events. Afte that set item delegate. And wala it will work

Can I use mousePressEvent in abstractitemdelegate?

Btw, I want make different emit signal for left and right click on combobox item.

Yes of course and now example for mouseevent:

void mouseReleaseEvent ( QMouseEvent * event )
	{
	  if(event->button() == Qt::RightButton)
	  {
             emit rightClick();
	  } 
	  if(event->button() == Qt::LeftButton)
	  {
             emit leftClick();
	  } 	  
 
	};

void mouseReleaseEvent ( QMouseEvent * event )
	{
	  if(event->button() == Qt::RightButton)
	  {
             emit rightClick();
	  } 
	  if(event->button() == Qt::LeftButton)
	  {
             emit leftClick();
	  } 	  
	  
	};

To copy to clipboard, switch view to plain text mode 

You can use mouseReleaseEvent or MousePressEvent

Not work

void ComboBoxDelegate::mousePressEvent(QMouseEvent *e)
{
    if (e->button()==Qt::LeftButton) {
        qDebug() << "Klik Kiri";
    }
 
    if (e->button()==Qt::RightButton) {
        qDebug() << "Klik Kanan";
    }
}

void ComboBoxDelegate::mousePressEvent(QMouseEvent *e)
{
    if (e->button()==Qt::LeftButton) {
        qDebug() << "Klik Kiri";
    }

    if (e->button()==Qt::RightButton) {
        qDebug() << "Klik Kanan";
    }
}

Btw, how can I know index of item selected?

Oh sorry my mistake i mean QItemDelegate
At first you must have working delegate like in this example http://programmingexamples.net/wiki/...mboBoxDelegate and when you own delegate works you can implement mouseEvent if it will not work post here you code.

Of course I use QItemDelegate. But not work

#ifndef COMBOBOXDELEGATE_H
#define COMBOBOXDELEGATE_H
 
#include <QItemDelegate>
 
class ComboBoxDelegate : public QItemDelegate
{
    Q_OBJECT
public:
    explicit ComboBoxDelegate(QObject *parent = 0);
 
protected:
    void mousePressEvent(QMouseEvent *e);
 
signals:
 
public slots:
 
};
 
#endif // COMBOBOXDELEGATE_H

#ifndef COMBOBOXDELEGATE_H
#define COMBOBOXDELEGATE_H

#include <QItemDelegate>

class ComboBoxDelegate : public QItemDelegate
{
    Q_OBJECT
public:
    explicit ComboBoxDelegate(QObject *parent = 0);
    
protected:
    void mousePressEvent(QMouseEvent *e);

signals:
    
public slots:
    
};

#endif // COMBOBOXDELEGATE_H

#include "comboboxdelegate.h"
#include <QMouseEvent>
#include <QDebug>
 
ComboBoxDelegate::ComboBoxDelegate(QObject *parent) :
    QItemDelegate(parent)
{
}
 
void ComboBoxDelegate::mousePressEvent(QMouseEvent *e)
{
    if (e->button()==Qt::LeftButton) {
        qDebug() << "Klik Kiri";
    }
 
    if (e->button()==Qt::RightButton) {
        qDebug() << "Klik Kanan";
    }
}

#include "comboboxdelegate.h"
#include <QMouseEvent>
#include <QDebug>

ComboBoxDelegate::ComboBoxDelegate(QObject *parent) :
    QItemDelegate(parent)
{
}

void ComboBoxDelegate::mousePressEvent(QMouseEvent *e)
{
    if (e->button()==Qt::LeftButton) {
        qDebug() << "Klik Kiri";
    }

    if (e->button()==Qt::RightButton) {
        qDebug() << "Klik Kanan";
    }
}

I only need catch mouse event. And get what item index is selected...

[Viper666]

I will write a example for you. But now i can' sorry. I don't know why it doesn't work but i think it has some solution

[wirasto]

Oh, no problem.
Btw, thanks for your response

[Viper666]

ok i solved it.
Solution: in QItemDelegate isn't mousePressEvent or something like that this are events from Qobject but this don't work for QItemDelegate you need implement editorEvent:

bool Item::editorEvent(QEvent *event, QAbstractItemModel *model, const QStyleOptionViewItem &option, const QModelIndex &index)
{
 
      if (event->type() == QEvent::MouseButtonPress)
      {
          QMouseEvent *mouseEvent = static_cast<QMouseEvent*>(event);
          if(mouseEvent->button() == Qt::LeftButton)
              qDebug() << "leftButton";
 
 
 
          if(mouseEvent->button() == Qt::RightButton)
              qDebug() << "rightButton";
      }
}

bool Item::editorEvent(QEvent *event, QAbstractItemModel *model, const QStyleOptionViewItem &option, const QModelIndex &index)
{

      if (event->type() == QEvent::MouseButtonPress)
      {
          QMouseEvent *mouseEvent = static_cast<QMouseEvent*>(event);
          if(mouseEvent->button() == Qt::LeftButton)
              qDebug() << "leftButton";
      


          if(mouseEvent->button() == Qt::RightButton)
              qDebug() << "rightButton";
      }
}
