    i guess it a variant of bin packing that is used.

    yes exactly, basically it's bin packing. You can design it really simple or pretty smart. There are numerous ways to implement such layout. Depending on the features desired.

    My implementation for example has the ability to stretch a certain item over 2 columns/rows. Making an item more present in the layout.

    I hope i can provide the plugin sometime this year. Will make an anouncement in the showcase sub-forum ;)

      yes, it's on git but also it's private :)

      It's not determined yet if it will be a commercial or an open-source product in the end.
      Beta testing will be free though. ;)

      Nevertheless i created the topic now and will post any news there in the future for everyone who is interested.

          Maybe Flow can suit You?

          As far as I can see Flow doesn't work with a model like Gridview does.

            And what if to squeeze Repeater inside the Flow?

              I don't know. Gridview creates and destroys delegates as needed. If I'll put a repeater in Flow and I have let's say 500 images, they would all have to be loaded to memory.

                I've already tried a Repeater with dynamically changed model size. Seemed to work and when size was decreased items were deleted (I believe...)
                But better I will not mess You up. This is already out of my experience.

                  Can you elaborate a bit more about how and what you did, so that I may try it too ?

                    If I were You, I might try something like this:

                    Flow {
                      Repeater {
                        model: yourData.length
                        Image {
                          source: yourData[index]
                          sourceSize.height: 200 // or other fixed value
                        }
                      }
                    }
                    

                    If yourData is QStringList or just QML array of strings, it can be directly set as a model of the Repeater:

                     model: yourData
                    

                    and accessible inside Image this way:

                    source: modelData
                    

                    I hope this is some clue for You

                      @SeeLook

                      This could work... I'll have to check if it disposes of elements that aren't visible.

                          @SeeLook Looks like the model can be a QAbstructListModel which is exactly what I use...
                          It's interesting, I'll try this out.

                          Other problems are the insert and remove function that GridView supports, as well as the shouldfechmore and fetchmore functions. (implemented inQAbstructListModel)
