QT Resource load too slow at start up and not be able to load from QThread::run

[TrungThanhMtad]

I have a problem:
I use some image in qt resource (.qrc file) but application load resource too slow at startup. (user have to wait about 1 minute or more)


So, I try to load resource in another thread using QThread.
But in QThread::run, it can not load resource correctly.

Here is my code:
I call StartT to start the loading resource thread.


#ifndef SPLASHFORM_H
#define SPLASHFORM_H

#include "ui_SplashForm.h"

class SplashForm : public QDialog, private Ui::SplashForm {
Q_OBJECT
public:
SplashForm(QWidget *parent = 0);
public slots:
void OnThreadFinished();
void StartT();
protected:
void changeEvent(QEvent *e);
};

#endif // SPLASHFORM_H



#include "SplashForm.h"
#include <QThread>
#include <QFile>
#include <QMessageBox>
//#include <iostream>
//using namespace std;
class LoadResourceThreadublic QThread
{
public:
LoadResourceThread(QObject* aParent):QThread(aParent),iSize(-10),aRunned(false) {};
int iSize;
bool aRunned;
protected:
virtual void run()
{

//QFile aFile(QString::fromUtf8(":/images/ttlogo16x16.png"));
//iSize = aFile.readAll().size();
QPixmap aPxm(QString::fromUtf8(":/images/ttlogo16x16.png")) ;
iSize = aPxm.height();//aFile.readAll().size();
aRunned = true;
//cout<<iSize<<" from run";

// QIcon icon;
// icon.addFile(QString::fromUtf8(":/images/ttlogo16x16.png"), QSize(), QIcon::Normal, QIcon::Off);
// if (icon.pixmap(20,20).height() > 0)
// QMessageBox::information(NULL , "Load finished" , "Icon OK Finished" );
// else
// QMessageBox::information(NULL , "Load finished" , "Icon not ok Finished" );
}

};

SplashForm::SplashForm(QWidget *parent) :
QDialog(parent){
setupUi(this);

}

void SplashForm::StartT()
{
// QPixmap aPxm(QString::fromUtf8(":/images/ttlogo16x16.png")) ;
// int iSize = aPxm.height();//aFile.readAll().size();
// if (iSize)
// QMessageBox::information(this , "Load finished" , "StartT Finished ok" );
//

LoadResourceThread* aLoadResourceThread = new LoadResourceThread(this);
connect(aLoadResourceThread , SIGNAL(finished()) , this , SLOT( OnThreadFinished() ) );
aLoadResourceThread->start();
}
void SplashForm::changeEvent(QEvent *e)
{
QWidget::changeEvent(e);
switch (e->type()) {
case QEvent::LanguageChange:
retranslateUi(this);
break;
default:
break;
}
}

void SplashForm::OnThreadFinished()
{
LoadResourceThread* aThread = dynamic_cast<LoadResourceThread*>(sender() );
if (aThread && aThread->aRunned)
{
if (aThread->iSize > 0)
QMessageBox::information(this , "Load finished" , "Finished ok" + QString::number(aThread->iSize ) );
else
QMessageBox::information(this , "Load finished" , "Finished not ok"+QString::number(aThread->iSize ) );

}
this->accept();
}


Please help me how to solve this problem
thanks in advance.

I try it in QT for PC then it is OK but when build in symbian it always fail to load resource from new thread.

Qt resources are implemented using a static char* array that contains the resource data. These data gets compiled into your application executable. It will make the application size bigger. I read somewhere else that static data is somehow bad on symbian and should be avoided. You could either try to load the files from filesystem or use http://wiki.forum.nokia.com/index.ph...rce_Access_API to access a native symbian resource file.
