2 times click instead of double click (eg. renaming)

Hi all,

I ame looking for a way to check whether a user pressed the left mouse button twice within a minimal time periode, but which is different from the double click signal. I want to use this for renaming a qlistview item as this is normally done. At the moment I use the double click signal and the renaming works fine, but I would like to connect the renaming to the "2 times click" as this is normally done for renaming. How can I do this?

Thanx!

You can use the QWidget::mousePressEvent() and mesure the time between two of those...

I will try that.

Do you have any idea what the usual time delay between the two clicks is when renaming an item?

For sure it should be more than QApplication::doubleClickInterval ()

I have a solution!

You can connect QListWidget::itemClicked(QListWidgetItem* item) signal to a slot (i.e. MyWidget::listItemClicked(QListWidgetItem* item)) like

Code:

---

void MyWidget::listItemClicked(QListWidgetItem* item)
{
    if(listWidget->itemIsSelected(item))
    {
        // Clicked item is previously selected
        // Edit item
    }
    else
    {
        // Select the item
        listWidget->setCurrentItem(item);
    }
}

---

In this way user can edit list item text selecting item and then clicking on it (like Windows icon text).

Bye

Something very strange is happening... During my testing for the sollutions given above I came accross the following:

I have written some testcode as shown below . If you run this, you can see that renaming seems to be already implemented in QT and all you have to do is catch the itemRenamed.... I have never seen this before, but it seems to work fine! The connection below makes sure you can do whathever you want when an item is renamed...

mylistview.h

Code:

---

#ifndef mylistview_h
#define mylistview_h
 
#include <qlistview.h>
#include <iostream>
 
class MyListView : public QListView
{
   Q_OBJECT
 
public:   
   MyListView(QWidget* parent = 0, const char* name = 0, WFlags f =0);
 
public slots:
      void slotTestRename(); 
};
 
#endif

---

mylistview.cpp

Code:

---

#include "mylistview.h"
 
MyListView::MyListView(QWidget* parent, const char* name, WFlags f) 
: QListView(parent, name, f)
{
   connect(this, SIGNAL(itemRenamed(QListViewItem* , int)), this, SLOT(slotTestRename())); 
}
void MyListView::slotTestRename()
{
   std::cout << "RENAMED " << std::endl;
}

---

mainfile:

Code:

---

#ifdef HAVE_CONFIG_H
#include <config.h>
#endif
 
#include <stdio.h>
#include <stdlib.h>
#include <qapplication.h>
#include <mylistview.h>
 
int main(int argc, char *argv[])
{
  QApplication a(argc,argv);
 
  MyListView* listview = new MyListView();
  listview->addColumn("testcolumn");
 
  a.setMainWidget(listview);
 
  QListViewItem* item = new QListViewItem(listview);
 
  item->setText(0, "trial");
  item->setRenameEnabled(0, true);  
 
 
  listview->show();
 
  //myMainWindow->showMaximized();
 
  return a.exec();   
}
