When in HiDPI settings, transactiondescdialog is too small initially, though it is re-sizable. the reason is that it uses hard-coded size in .ui file. hard-coded to have size
<width>620</width>
<height>250</height>
That's problematic on platform that don't use pixel ratio, but just pre-monitor DPI settings, like windows >= 8 and Linux.
initial size should be set by overloadding sizeHint() and use this->fontMetrics() to calculate a proper size.
initial size:
well, it should be
@jonasschnelli Mind having a look? You're the HiDPI expert ^^.
Yes. There are serval HiDPI issues on Linux. But IMO its mostly a upstream Qt issue. HiDPI works fine on mac and it should also work fine on Linux and Win (if Qts HiDPI behavior would be platform independent). I strongly discourage from adding linux specific HiDPI fixes (especially #ifdefs!). Well, there are some things like font size definitions which should/could be changed to allow more flexible size calculations (like #5898).
I have a Linux/Ubuntu HiDPI setup ready and i'd like to test soon a bitcoin-qt with Qt5.4. If there are still things on "our side" to cure, i'd like to see them fixed together in on PR.
