Set tiled wallpaper of Desktop

[samdol]

What is the good way to set tiled wallpaper of desktop using jpg file? Do I have to change it to other format? I couldn't find on Qt document. Does Qt itself support this?

You can use jpeg format for setting it as Desktop Wallpaper. Please see this link , sample code from Mr. @mrjj .

Thank you for the link. This seems set a stretched picture as wallpaper. Is there a way to set a tiled pictures as a wallpaper?

Hi, I think you need to set that as registry

// set reg
HKEY_CURRENT_USER\Control Panel\Desktop\TileWallpaper to 1
You can use
http://doc.qt.io/qt-5/qsettings.html
for that as far as i know. (never tried it)
Something like:

QSettings settings("HKEY_CURRENT_USER\\Control Panel\\Desktop", Setting::NativeFormat);
settings.setValue("TileWallpaper ", "1");

 // Refresh the background
SystemParametersInfo(SPI_SETDESKWALLPAPER, 0,  NULL, SPIF_UPDATEINIFILE);

Thank you mrjj.
Just for minor correction.
settings.setValue("TileWallpaper ", "1");
Then it works.
