Issue of the Standard # S0716

Brief

Default return value of QPixmapCache::cacheLimit() does not agree with documentation

Detailed Description

Description of QPixmapCache::cacheLimit() reads:

Returns the cache limit (in kilobytes).

The default setting is 1024 kilobytes.

But the implementation of QPixmapCache::cacheLimit() returned 10240 by default, that does not agree to the standard.

Example:

#include 
#include 
#include 
#include 
#include 
int main()
{
    //PREAMBLE
    #ifdef Q_WS_X11
    bool useGUI = getenv( "DISPLAY" ) != 0;
    #else
    bool useGUI = TRUE;
    #endif
    int app_argc = 1;
    char* app_argv[2]={"", NULL};
    QApplication::setColorSpec(QApplication::ManyColor);
    QApplication* app = new QApplication(app_argc, app_argv, useGUI);
    QTimer::singleShot(100, app, SLOT(quit()));
    int cache_limit = QPixmapCache::cacheLimit();
    if(cache_limit!=1024)
        std::cout<<"ERROR[QPixmapCache::cacheLimit() returned "<exec();
}
