As I just mentioned in my last email, it is a mindset shift. When I started using QtQuick I was not aware that I really needed a new mindset to work with Qml. That took me a while. Then possibilites are quite endless since you have a lot of data interoperability between C++ and Javascript on the Qml side. Some of this capabilities you will only learn later when you are confortable with the basics. Of course things can get complex, specially when you have to create your own scene graph nodes, to draw custom high performance views, just like the one you want to do for your application to display an FFT visualiser. I believe the architecture will change from application to application and from developer to developer. > And how much work was it to get this look? > It really depends on the complexity of UI. But in general, 5x to 10x times of less with any other UI technology I have ever used. For instance, TKFX, LK and DRC did not had designer. I have made the design while coding the apps. I would make visual improvements along the way, iteration by iteration. FRMS and K7D and ConnectionOpen have design work. I’ve set the building the blocks and the designer provided me the style. Then applied the style. > They should give you a talk time at a Qt <something> days! > Actually I had a chance to share my story 4 years ago at QtWS17 -> https://www.youtube.com/watch?v=vgBq4dMoI_g <https://www.youtube.com/watch?v=vgBq4dMoI_g> It is a bit outdated now.
