Previously reported issues were tested and found
to be resolved in this beta.
j601 t beta issues
* Grid Demo - Development Triangle
Stack Error on pressing Enter or Mouse Click in Windows,
and Java vanishes without a trace
* Grid needs setfocus on mouse-down event (known issue)
* Events Demo - tab to isigraph, and there's
no way to dismiss the popup, only to kill process
* Java FE sysdata returns nagatives with "-" not "_" as Windows FE
should be "_" in both places, because it's for internal use
* In Java FE, Input Log (Ctrl+D)
- list does not get focus
- enter does not select
- dismissal (close [X]) pastes text anyway
- Escape doesn't work
- (in general, would be good if it prepended prompt ' ')
* viewrgb used to initially (before stretch)
preserve bitmap size, padding with default color (black)
Now it stretches right away, and there is no way to
view undistorted bitmaps smaller than 128 pixels or so.
This is essential when working with image transformations
to test on actual small images (loaded from file, e.g.)
viewrgb 16bff* 2| !/~i.32 NB. stretches right away
* > should also be called not "gedit"
I meant the window title (pn), like "View Definition"
Also it could be shared between all demos with a callback
* Java gltext gives domain error, unless glfont is set first,
Windows is OK, it uses System fornt. Maybe Forms font
could be used as default. see focus.ijs
* Java rectangle is 1 pixel larger than Windows, see focus.ijs
I think this should be compensated in gl2 engine.
* Mac fonts are smaller than Windows fonts, to be exact
The ratio reflects 96/72 DPI between Windows and Mac
As a result, fonts are disproportional to geometry
as shown in Plot demo. Grid uses some magic so
that fonts fit, but that may be non-standard (cheating).
Look what Safari does: they swallow their pride and
compensate this to be compatible with the rest of the world.
I think J should do the same (less the pride part).
