Icons from resource file not showing

@saber

Delete your build folder. Clean your project, qmake and build and then run your project.

[saber]

I did it .but no change.
I think it is in code to select the icon from theme.
the app is "lximage-qt"

Hi,

Please show the content of your .qrc file and the part of the code where you load the icons.

[saber]

Here is the qrc file

I use this code first

  QPixmap iu("<:/icons/before.png>");
   ui.cNext->setIcon(iu);

But not showing the icon.
so i apply the icons from designer
and also see the output .the icon is not showing in after build.

thanks.

@saber hi,friend.welcome.

try following snippet:

ui->pushButton->setIcon(QIcon(":/icons/left.ico"));

or

ui->pushButton->setIcon(QIcon("qrc:/icons/left.ico"));

[saber]

as i am using qt 5 i used
ui.cPrevious->setIcon(QIcon("qrc:/icons/left.ico"));

but no result.I don't understand .It should work with code and designer.
i think writer of this code made something to take only select the icone from system theme.

@saber hi, you use cmake. maybe some error in cmake. like source path not set right.

if use qmake, my snippet code is ok. you can check the the path in cmake.

or To try the absolute path. like following snippet:

QPixmap pix;
if(pix.load("absolute icon path")){
    qDebug("icon load ok");
    QIcon ico(pix);
    ui->btn->setIcon(ico);
}
