Hi,
I want to access file icons of the OS, I need them in "good quality",
but the available sizes are apparently only available in 16x16 and 32x32
px.
My system is Windows 10 64bit, Qt 5.7.1, MinGw 5.3.0
Please find a minimal compileable example attached. FYC the relevant
part is pasted here:
@
QFileIconProviderprovider;
QDirdir("c:/");
for(autoinfo:dir.entryInfoList()){
qDebug()<<info.fileName()<<provider.icon(info).availableSizes();
}
@
The output is like
"AndroidSDK" (QSize(16, 16), QSize(32, 32))
"apache-ant-1.9.6" (QSize(16, 16), QSize(32, 32))
"Drivers" (QSize(16, 16), QSize(32, 32))
"eula.1031.txt" (QSize(16, 16), QSize(32, 32))
"Intel" (QSize(16, 16), QSize(32, 32))
"JavaJDK" (QSize(16, 16), QSize(32, 32))
"Oh Freedom.mp3" (QSize(16, 16), QSize(32, 32))
"Program Files" (QSize(16, 16), QSize(32, 32))
[...]
I would have expected higher icon resolutions (64x64 and more) to be
present.
Is this a bug or perhaps a (possibly performance related) restriction?
Or am I doing/expecting something stupid here...?
Best regards,
Sebastian
