Well, that's a good example: setting a factor, not the absolute value. > > Moreover, I can have two different monitors connected to the same output > > (at different times, of course).

The problem on that one is that you're forcing me to keep a value per each individual monitor I connect to regularly. With the laptop's display panel, that's 4 or 5. Since they are different actual monitors, each has their own DPI value, which is obtained by Qt. And some monitors report wildly incorrect DPI values, like a 27" monitor saying it's 160x90mm in size. So what's the policy for a brand new monitor we connect to (say, a projector in a conference room)? Does it: a) keep the physical one from the monitor? b) use 96x96? c) use one of the other monitor's settings? (hint: a, b and c are wrong) Right now, I need exactly two values: the display panel's multiplicative factor of 2 and the external output's multiplicative factor of 2. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel System Software Products _______________________________________________ Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
