Bug 1358: 'Honor' SWT's projection of High-DPI Scaling (Reading hidden
pixel dimensions)
Christian reported this bug and described multiple pathways.
This change usese the following:
- access to getClientAreaInPixels w/ fallback of
- DPIUtil.autoScaleUp(getClientArea())
I hardly have tested this on Linux/GTK, even though I use a High DPI
monitor, maybe just because of it and Eclipse _poor_ state of proper UI
Christian: Please test this .. if buggy, reopen quick for release 2.4.0
SWT/GTK High-DPI is a PIA:
- GDK_SCALE renders offscreen and scales the image (wow & ugly)
- GDK_DPI_SCALE works at least on the fonts properly
- swt.autoScale is pretty much like: What will be scaled?
It scales some icons in Eclipse, not fonts and result in Eclipse
looks horrible.
Maybe I just made this patch to vent about this poor state of things.
Notable: KDE looks great and uses DPI, firefox some GDK_DPI_SCALE
equivalent (OK)
One also wonders why there is only a single scale dimension, where DPI
differs x/y! But enough of my rant :)
