    does not work, because standardIcon is not a static member o.O
    But i cannot make an instance of it, because it's abstract.

      QIcon myIcon =QApplication::style()->standardIcon(QStyle::SP_TitleBarMinButton);

          const auto avalSize = myIcon.availableSizes();
          QIcon invertedIcon;
          for(auto& singleSize : avalSize){
          QImage tempImage = myIcon.pixmap(singleSize).toImage();
          tempImage.invertPixels();
          invertedIcon.addPixmap(QPixmap::fromImage(std::move(tempImage)));
          }

            The maximize icon worked fine, but the minimize is not very good. Any ideas what may happened here??

              @VRonin i need your help once more.

              There are a few new findings. I need this splashscreen for a plugin that is compiled to .dll Because it's really much overhead to compile, deactivate the plugin, copy the dll, activate the plugin, test it, change code,... i copied a few parts to a test project. It's the same code, but different results.

              Sourcecode for the whole plugin: https://git.rwth-aachen.de/carstenf/qtTsOverlay/tree/master
              Test project: https://git.rwth-aachen.de/carstenf/testProject/tree/master

              Plugin:
              the minimize icon looks like on the picture above
              the maximize icon works fine
              when i select a item it is slightly highlighted white and the icon becomes a blue hue
              when something is selected and i press the button or switch to an other window the text does not change, the highlight disappears, the icon is white again

              Test application:
              the minimize and maximize icon work both
              when i select a item it gets a black dotted border and the icon becomes a blue hue
              when something is selected and i press the button or switch to an other window the text become black, the dotted border disappears, the icon is still blue

              Why is there this different behaviour and how can i fix it to this:
              the minimize and maximize icon work both :P
              when i select a item there is no highlight, no text an icon changes.
              when something is selected and i press the button or switch to an other window nothing changes

                QIcon invertedIcon;
                for(auto singleMode : {QIcon::Normal,QIcon::Disabled,QIcon::Active,QIcon::Selected}){
                for(auto singleState : {QIcon::On,QIcon::Off}){
                const auto avalSize = myIcon.availableSizes(singleMode ,singleState );
                for(auto& singleSize : avalSize){
                QImage tempImage = myIcon.pixmap(singleSize,singleMode ,singleState).toImage();
                tempImage.invertPixels();
                invertedIcon.addPixmap(QPixmap::fromImage(std::move(tempImage)),singleMode,singleState);
                }
                }
                }

                  @VRonin still the same problem (updated the source on the repo.)

                  But the wrong icon the one thing, the other is that blue hue at the icons from the list entries

                    yes, this just inverts the colours of every icon. it will will just take a negative (like good old film cameras do), if you want to do something more refined, then that just replace tempImage.invertPixels(); with whatever pixel manipulation you want to apply. I also forgot the state and modein myIcon.pixmap above, fixed now

                      @VRonin invert is just fine. It works in the testsoftware. But in the final plugin (same code you can check it in the repositories i posted) it does not work
