Hi All,
I am trying to add a spinner to QStackwidget, i am having 5 frame pages in the stackwidget with 5 buttons below in a seperate frame and when i press the 1st button it should load the spinner image in the frame page and similarly for all others.. In my application,when i give these below codes i am not able to get it.

QAnimationLabel* spinner = new QAnimationLabel(":images/spinner-24x24.gif", this);
spinner->start();

QVBoxLayout* layout = new QVBoxLayout;
layout->addWidget(spinner, 0, Qt::AlignCenter);
QFrame* frame = new QFrame;
frame->setLayout(layout);
setCentralWidget(frame);

It's not accepting the SetCentralWidget(frame); and i could not find any solution for this.
Answers will be highly appreciated!!!

Thanks in Advance and Regards,

Hi Amleto,
I am extremely sorry for the code!!! I will explain you clearly again this whole thing!!
I am having a stackwidget with 5 frames displaying the list widget and 5 buttons below the stackwidget frame.. If i select the 1 button page1 list is displayed.,.. similarly for all the other pages the list gets displayed. I need to add a loader(.gif image) into each page when i press the button. I am not able to display that in that frame in the stackwidget.I tried the above code to show it in the central layout but could not do it.
Is there any solution for bringing the loader in-between the loading page time???

Sorry Again and Thanks in Advance and Regards,

Hi Amelto,
I mean loader page should be visible in-between the time of button pressed and loading the page!!!
I had downloaded the API from one link and tying to use them in my application!!!
The same concept as it follows in it.. i am trying to keep 5 buttons below and when i press it should load when clicked.
In that i am using stackwidget with listwidgets placed above it.When i give that code which was given earlier i could not port them into my app

Thanks in advance and Regards,

Hi Amelto,
I had kept the qstackwidget in the ui design part and have not used in the code.Centerpart is qstackwidget and at the bottam we have 5 buttons.

I have divided the pages into 2 frames,say 80-20.. 80% for displaying the listwidget,.,. this listwidget are placed over the each page of the stackwidget to display the listview and bottam area for displaying the 5 buttons.,when i click on each button one of the frames get loaded.
Whenever i click a button the loading image(.gif image) should start and whenever the page has been loaded the image should disappear.
This is what i am trying.,

My problem is i have tried loading this image from mainwindow.cpp to load this page. it works fine, but when i tried in homescreen where we have placed the stackwidget and bottom with buttons.
i couldn't manage to bring the loading image. as said i have 5 buttons at the bottom when i click any one of the button i used to display the image, as follows

void homescreen::onbutton1clicked()
{
QAnimationLabel* spinner = new QAnimationLabel(":images/spinner-24x24.gif", this);
spinner->start();

QVBoxLayout* layout = new QVBoxLayout;
layout->addWidget(spinner, 0, Qt::AlignCenter);
QFrame* frame = new QFrame;
frame->setLayout(layout);
setCentralWidget(frame);
.................................
...................................
.................................
//code which i used to load the details which i get from the server to the screen.
.........................
............

and here i finally stop the .gif file animation loading once the details as been shown in the screen.
}

this is the prob i am facing.

Hi Amelto,
This is the actual code and actual prob....

Hi,
This is my click event slot for a button:

void Homescreen::setPage5()
{
ui->framePages->setCurrentIndex( 4 );

QAnimationLabel* spinner = new QAnimationLabel(":images/spinner-24x24.gif", this);
spinner->start();

QVBoxLayout* layout = new QVBoxLayout;
layout->addWidget(spinner, 0, Qt::AlignCenter);
QFrame* frame = new QFrame;
frame->setLayout(layout);
ui->framePageCalls->set(frame);

MainWindow::identification.append("checkin");
QByteArray postData("");
QList<QPair<QByteArray, QByteArray> > headers;

postData = postBody.toAscii();
if (!HttpCommunicator::splitIntoHeaders("", headers)) {
//ui->m_textBrowserResp->setText(tr("Failed to parse HTTP headers."));
return;
}
HttpCommunicator::HttpRequestType requestType = HttpCommunicator::httpRequestTypeForText("POST");
m_httpCommunicator = new HttpCommunicator(requestType,"http://.....", postData, headers, "True");

QEventLoop loopforactivity;
connect(m_httpCommunicator,SIGNAL(finishedRequest()),&loopforactivity,SLOT(quit()));
m_httpCommunicator->makeRequest();
loopforactivity.exec();
QList<QString> Name;
QList<QString> Address;
QList<QString> Distance;
QString name;
QString address;
QString distance;
QString configfile = QApplication::applicationDirPath() + "/config_file.txt";

QSettings setting(configfile, QSettings::IniFormat);
setting.beginGroup("checkin");
const QStringList childgroup = setting.childGroups();
int numberofgroup = childgroup.count();

for (int i=0;i<numberofgroup;i++)
{
QSettings setting(configfile, QSettings::IniFormat);
setting.beginGroup("checkin");
QString index = QString::number(i);
setting.beginGroup(index);
name = setting.value("Name", 4711).toString();
address = setting.value("address", 4711).toString();
distance = setting.value("distance", 4711).toString();
Name.insert( i,name );
Address.insert( i,address);
Distance.insert( i,distance);

setting.endGroup();
setting.endGroup();
}

contenttocheckin(Name,Address,Distance);
}

This is the total code for a single button!!!!!
Here is how i tried the loading image to this button

Hi Amelto,

This code works fine!!!!!
QAnimationLabel* spinner = new QAnimationLabel(":images/spinner-24x24.gif", this);
spinner->start();
QVBoxLayout* layout = new QVBoxLayout;
layout->addWidget(spinner, 0, Qt::AlignCenter);
ui->framePageCalls->set(layout);
........

spinner->stop();

Thanks for your help and support!!!
