Re: [Factor-talk] Listener on Windows - UI Corruption

You can never exclude anything, but it seems very unlikely that the GC would be the problem. The GC copies objects so it is vulnerable to shadow data bugs. That is, some references might no be updated to point to the newly copied to location for the object. In the listener, you can run the minor-gc and gc words and see if there is a pattern or if you are able to trigger the bug that way. You can also recompile Factor to run in debug mode: nmake /f Nmakefile x86-64 DEBUG=1 Also I see that you are running Factor in compatibility mode because the fonts are all blurry. That is automatically enabled in Windows for Factor if you have a high dpi screen. You can try and disable it by right-clicking the .exe file and go: Properties -> Compatibility -> Inactivate scaling when using High DPI. -- mvh/best regards Björn Lindqvist -- Find and fix application performance issues faster with Applications Manager Applications Manager provides deep performance insights into multiple tiers of your business applications.

[Factor-talk] Coordinates of child gadgets
Hello!
I have the following code:
USING: kernel typed literals accessors assocs sequences math math.vectors
opengl ui.gadgets ui.render colors colors.constants locals arrays
namespaces ;
IN: iqlink.field
TUPLE: inner-gadget < gadget ;
TUPLE: outer-gadget < gadget ;
M: inner-gadget pref-dim*
drop { 10 10 } ;
M: inner-gadget draw-gadget*
loc>> { 10 10 } gl-fill-rect ;
: add-inner-gadget ( index parent -- )
swap 10 * dup 2array
inner-gadget new swap >>loc
add-gadget drop ;
: ( -- outer-gadget )
outer-gadget new dup [ add-inner-gadget ] curry
3 iota swap each ;
M: outer-gadget pref-dim*
drop { 60 60 } ;
M: outer-gadget draw-gadget*
drop "red" named-color gl-color gl-error ;
Run with: [ "OuterGadget" open-window ] with-ui
The outer-gadget simply creates three instances of inner-gadget and keeps
them as children. All inner-gadgets have the same size 10x10 pixels.
The outer-gadget positions its children at coordinates { 0 0 }, { 10 10 } and
{ 20 20 } by setting their loc slot.
It is therefore expected that the resulting image will consist of three red
squares aligned diagonally end to end (see "expected.png").
However, the result is different (see "actual.png").
Why the difference? Is there a hidden coefficient I'm not taking into account?
I can get the expected image if I replace 10 with 5 in add-inner-gadget. I
don't understand this.

Re: [Factor-talk] Coordinates of child gadgets
Hello!
> I have the following code:
Never mind that last post, I figured it out.
I missed the fact that while drawing a child gadget the { 0 0 } coordinate is
already at the top-left corner of the child. The additional shift by loc was
messing things up.
