Flickable in qt

[pragati]

Hi all,

I have a Gui screen which is working fine. But I am out of space in the screen, hence I have to add the scroll feature in this screen. Since it is a touchscreen hence i want to use a flickable scroll bar in it.

Can you please help me to understand how to start for this, I had gone through qt examples but they all deal with List widget....which is not in my case. I don't want to disturb the Gui of my screen I just want to add the flickable scrolling feature in it.
Is that possible? If yes, then how it can be done.

Thanks in advance,
Pragati

If you are not on QML (whose lists are flickable by default) the "flick charm":http://labs.qt.nokia.com/2008/11/15/flick-list-or-kinetic-scrolling/ might be of interest for you, which supports all C++ classes inheriting QAbstractScrollArea (there is a "solution":http://labs.qt.nokia.com/2009/07/19/kinetic-scrolling-on-any-widgets/ for classes not inheriting it as well, which is slightly more complicated).

Yeah I am not on QML......So its complicated than a simple scrollbar...or equivalent.....;)

I have to use scroll feature anyhow but flickable will be better so thought to give it a try....I don't know from where and how to start....Thanks for your reply....:)

These two examples which you had mention I have gone through tjem but they are expalined for just how to make a qlist flickable...am i right here?

I am not using any of it...I will show you one of my screen's code:

DMMMenu.h:

@
#ifndef DMMMenu_H
#define DMMMenu_H
#include <QtGui>
#include <QWidget>
#include "../../DMM/Include/Voltage.h"
#include "../../DMM/Include/Current.h"
#include "../../DMM/Include/Resistance.h"
#include "../../DMM/Include/Memory.h"
namespace DMM
{
namespace Ui {
class DMMMenu;
}
class DMMMenu: public QWidget
{
Q_OBJECT

public:

DMMMenu(QWidget *parent = 0);
~DMMMenu();

public slots:
void OnVoltageClicked();
void OnCurrentClicked();
void OnResistanceClicked();
void OnMemoryClicked();
private:
Ui::DMMMenu *ui;

public:
DMM::Voltage *voltage;
DMM::Current *current;
DMM::Resistance *resistance;
DMM::Memory *memory;
};

}

#endif // DMMMenu_H

@

DMMMenu.cpp

@
#include "../../DMM/Include/DMMMenu.h"
#include "ui_DMMMenu.h"
#include <QDateTime>

namespace DMM
{

DMMMenu::DMMMenu(QWidget *parent) :
QWidget(parent),

ui (new Ui::DMMMenu)

{

ui->setupUi(this);

voltage=new Voltage();
voltage->HO = this;
voltage->hide();

current=new Current();
current->current_home =this;
current->hide();

resistance=new Resistance ();
resistance->resistance_home=this;
resistance->hide();

memory=new Memory ();
memory->Memory_home=this;
memory->hide();

connect(ui->voltage_Button, SIGNAL(clicked()), this, SLOT(OnVoltageClicked()));
connect(ui->current_Button, SIGNAL(clicked()), this, SLOT(OnCurrentClicked()));
connect(ui->resistance_Button, SIGNAL(clicked()), this, SLOT(OnResistanceClicked()));
connect(ui->memory_Button, SIGNAL(clicked()), this, SLOT(OnMemoryClicked()));

//get current date
QDate date = QDate::currentDate();
QString dateString = date.toString();
ui->Label_Date->setText(dateString);

// get current time
QTime time = QTime::currentTime();
QString timeString = time.toString();
ui->Label_Time->setText(timeString);

}

void DMMMenu::OnVoltageClicked()
{
voltage->show();
this->hide();
}

void DMMMenu::OnCurrentClicked()
{
current->show();
this->hide();
}

void DMMMenu::OnResistanceClicked()
{
resistance->show();
this->hide();
}

void DMMMenu::OnMemoryClicked()
{
memory->show();
this->hide();
}

DMMMenu::~DMMMenu()
{

}

}

Yes, both solutions can be used to make lists flickable. Take a look at "QT-BUG9054":https://bugreports.qt-project.org/browse/QTBUG-9054 as well.

If Qt5 is an option for you take a look at "QScroller":http://doc-snapshot.qt-project.org/5.0/qscroller.html#details.

Okay ....thanks...will come back to you after going through these two links.....

Is Flickable scroll of widget is supported in Qt 4.0?

Hi all,

I followed exactly as explained in this link
http://qt-project.org/forums/viewthread/4059

Used the same qskinecticscroller.h and .cpp files but still my code is working not I am not able to scroll it......Is there any changes I have to make in theqs kinecticscroller files?

here is my .cpp file in which setupUi is mentioned

@

#include <QtGui>
#include "kinectic.h"
#include "ui_kinectic.h"
#include "QDateTime"
#include "scroller.h"

kinectic::kinectic(QWidget *parent) :
QWidget(parent),
ui(new Ui::kinectic)
{
ui->setupUi(this);

scroller = new Scroller(this);
scroller->enableKineticScrollFor(ui->scrollArea);

// // get current date
// QDate date = QDate::currentDate();
// QString dateString = date.toString();
// ui->label_date->setText(dateString);

// // get current time
// QTime time = QTime::currentTime();
// QString timeString = time.toString();
// ui->label_time->setText(timeString);
}

kinectic::~kinectic()
{
delete ui;
}

@

Include file for the same:

@
#ifndef KINECTIC_H
#define KINECTIC_H

#include "scroller.h"

#include <QWidget>
class Scroller;
namespace Ui {
class kinectic;
}

class kinectic : public QWidget
{
Q_OBJECT

public:
explicit kinectic(QWidget *parent = 0);
~kinectic();

private:
Ui::kinectic ui;
Scrollerscroller;
};

#endif // KINECTIC_H
