[vlc-devel] [PATCH] draw the toolbar with DPI-aware dimensions

[Jarrad Whitaker]

My current method should work with Qt4 (though I haven't tested, it
was pain enough getting the current build environment set up)
WRT the "recommended HDPI way", Qt's current advice is to "use Qt
Quick", which of course would involve re-writing the whole interface.
You may call me lazy but I have no intention of doing this! Qt does
have some hi-dpi patches incoming with better support for Qt Widgets,
but it looks like they'll be in Qt 5.5 at the earliest. The method I
am using is a very small change, and I would hazard that given it
actually gives perfectly good results (assuming we do it properly with
some high-res assets), it's probably not worth making more fundamental
changes until the promised proper DPI awareness is built into Qt.

I've actually just tried to get the qsvg library built as well, as it
would be required for vector toolbar icons, but I'm not having much
luck. It's building statically but the qt gui is not linking against
it, and my makespec to get it into contribs is a horrible mess that
doesn't deserve to see the light of day. Could I ask if someone more
familiar with the build system could have a look at this? once it
builds and links, it should be a simple matter of just adding some
SVGs into vlc.qrc and then adding them to the icons.

For now, I shall make up the SVGs themselves and export some high
resolution png icons from them. These can be put in with no changes to
the contribs and should still look decent. Also, the groundwork for
this will be required for later SVG support anyway.

Cheers
