    @JonB Yes that was my conclusion too, but finding such a lib has proven to be quite difficult. Building Poppler isnt exactly easy and there arent many alternatives to that aside from Hummus.

    @Trung-Ngo said in Qt multimedia warnings Qt 6.6.0: It does not have Qt 6.5.4 and Qt 6.5.5 It could be that these versions are not provided via installer for OSS users (only for commercial users). You would need to build that Qt version from source. But why don't you want to use Qt 6.6.x?

    @Dump What do you expect it to look like? but it will persist. It prevents the menu bar from being centered up and down. QMenuBar menus and actions are usually left aligned

    @quadbyte using QGuiApplication does not mean that you need to show something for your tool to work.

    @AnneRanch said in Passing multiple parameters to QProcess: params need to have only single item... Not quite correct. params is a QStringList. A LIST of QString. With the << operator you direct the right side to the left (i.e. the string list). params need to have only single item... So it's more like "You can add only one after another" (because QProcess needs every argument as separate string) As you might already know / have seen from @Axel-Spoerl 's suggestion to use qDebug() This params << "-fa"; params << "Monospace"; params << "-fs"; params <<"16"; produces: QStringList("-fa") QStringList("-fa", "Monospace") QStringList("-fa", "Monospace", "-fs") QStringList("-fa", "Monospace", "-fs", "16") Each element is a QString and the next to-be-added item is appended to the end of the list.
