pixmap or qimage second time usage in widgets ( platform S60 )

[ada10]

I have come across a scenario where I have to load the same pixmap / same QImage onto two different widgets ( belonging to the same mainwindow ).

First time I load a pixmap 1 on widget 1 , it works fine.
Second time if I try to load the same pixmap ( or QImage ) on another widget ( say widget 2), the code just throws some error ( saying memory full ) or does not load the pixmap on widget 2.

Ultimately I end up duplicating the png files i use to load the pixmaps, giving them distinct file names. Is there a solution to avoid this loading problem so that the I can use the same png file to be loaded any number of times ?

Why not reuse the same image instead of loading it again?

I faced the same issue with the usage of the same pixmap more than once when adding it to a model class ( without loading ). Is there a solution to this ?

Please provide a minimal compilable example reproducing the problem.

The code segment for this is as shown below -

gridLayout = new QGridLayout(mainwindow);
gridLayout->setObjectName(QString::fromUtf8("gridLayout"));
gridLayout->setContentsMargins(0, 0, 0, 0);
label = new QLabel(gridLayout);
label->setObjectName(QString::fromUtf8("label"));
label->setPixmap(QPixmap(QString::fromUtf8("../folder/user_group_icon.bmp")));
 
gridLayout->addWidget(label, 0, 0, 1, 1);
 
label_2 = new QLabel(gridLayout);
label_2->setObjectName(QString::fromUtf8("label_2"));
label_2->setPixmap(QPixmap(QString::fromUtf8("../folder/user_group_icon.bmp")));
 
gridLayout->addWidget(label_2, 0, 1, 1, 1);

gridLayout = new QGridLayout(mainwindow);
gridLayout->setObjectName(QString::fromUtf8("gridLayout"));
gridLayout->setContentsMargins(0, 0, 0, 0);
label = new QLabel(gridLayout);
label->setObjectName(QString::fromUtf8("label"));
label->setPixmap(QPixmap(QString::fromUtf8("../folder/user_group_icon.bmp")));

gridLayout->addWidget(label, 0, 0, 1, 1);

label_2 = new QLabel(gridLayout);
label_2->setObjectName(QString::fromUtf8("label_2"));
label_2->setPixmap(QPixmap(QString::fromUtf8("../folder/user_group_icon.bmp")));

gridLayout->addWidget(label_2, 0, 1, 1, 1);

Here the gridLayout is added to a mainwindow & contains 2 labels. Both set the same bmp file as pixmap. The first label displays it but the second label does not. This problem occurs ONLY ON S60 ( not on windows ).

Has anyone faced this issue before?

What if you do this:

QPixmap pixmap(QString::fromUtf8("../folder/user_group_icon.bmp"));
gridLayout = new QGridLayout(mainwindow);
gridLayout->setObjectName(QString::fromUtf8("gridLayout"));
gridLayout->setContentsMargins(0, 0, 0, 0);
label = new QLabel(gridLayout);
label->setObjectName(QString::fromUtf8("label"));
label->setPixmap(pixmap);
 
gridLayout->addWidget(label, 0, 0, 1, 1);
 
label_2 = new QLabel(gridLayout);
label_2->setObjectName(QString::fromUtf8("label_2"));
label_2->setPixmap(pixmap);
 
gridLayout->addWidget(label_2, 0, 1, 1, 1);

QPixmap pixmap(QString::fromUtf8("../folder/user_group_icon.bmp"));
gridLayout = new QGridLayout(mainwindow);
gridLayout->setObjectName(QString::fromUtf8("gridLayout"));
gridLayout->setContentsMargins(0, 0, 0, 0);
label = new QLabel(gridLayout);
label->setObjectName(QString::fromUtf8("label"));
label->setPixmap(pixmap);

gridLayout->addWidget(label, 0, 0, 1, 1);

label_2 = new QLabel(gridLayout);
label_2->setObjectName(QString::fromUtf8("label_2"));
label_2->setPixmap(pixmap);

gridLayout->addWidget(label_2, 0, 1, 1, 1);
