Hi,
Hi, i'm facing a problem drawing textures in a new window. when I
create the gadget and add it to the listener using gadget. the image
shows corretly, when I create the gadget and use open-window, the
image does not show up on the new window.
Sample code below:
TUPLE: i-gadget < gadget
image texture ;
: ( path -- gadget )
[ i-gadget new ] dip load-image >>image ;
M: i-gadget pref-dim*
image>> dim>> [ 20 + ] map ;
M: i-gadget graft*
dup find-gl-context
dup image>> { 0 0 } >>texture drop ;
M: i-gadget ungraft*
dup find-gl-context
dup texture>> dispose
f >>texture drop ;
M: i-gadget draw-gadget*
[ { 10 10 } ] dip texture>> [ draw-texture ]
curry with-translation ;
! In the listener
"vocab:images/sprites/game_drop.png" gadget.
! the above works and shows the image in the listener
"vocab:images/sprites/game_drop.png" "i-gadget" open-window
! the above opens a new window but the image does not show
What could I be missing?
Thanks,
Sankar

Re: [Factor-talk] Problem drawing an image in a new window
That could be a bug, or maybe a side effect of the design. Would you mind
opening an issue on github for us to look into later?
Thanks,

I see that moving the texture creation code from graft* to draw-gadget*
solves the issue. I'm wondering if this is a bug, since the
documentation for graft* mentions that resources can be allocated on
this method (and to use find-gl-context to ensure the correct GL context
is setup before allocating the resources).
The modified the code shown below works correctly:
M: i-gadget graft*
drop ;
M: i-gadget draw-gadget*
[ { 10 10 } ] dip
dup texture>> [ ]
[ dup image>> { 0 0 } >>texture texture>> ] ?if
[ draw-texture ] curry with-translation ;
image-gadget seems to have been implemented in the same way though (i.e.
setting up textures is done on the 1st call into draw-gadget*).
Thanks,
Sankar

Re: [Factor-talk] Problem drawing an image in a new window
There's an image-gadget implementation from images.viewer, maybe you
should start from that and expand to get all the functionnality you
need ?
IN: scratchpad
"resource:./misc/icons/factor_48...@2x.png" gadget.
"resource:./misc/icons/factor_48...@2x.png" "image" open-window

[Factor-talk] Problem drawing an image in a new window
Hi,
Hi, i'm facing a problem drawing textures in a new window. when I
create the gadget and add it to the listener using gadget. the image
shows corretly, when I create the gadget and use open-window, the
image does not show up on the new window.
Sample code below:
TUPLE: i-gadget < gadget
image texture ;
: ( path -- gadget )
[ i-gadget new ] dip load-image >>image ;
M: i-gadget pref-dim*
image>> dim>> [ 20 + ] map ;
M: i-gadget graft*
dup find-gl-context
dup image>> { 0 0 } >>texture drop ;
M: i-gadget ungraft*
dup find-gl-context
dup texture>> dispose
f >>texture drop ;
M: i-gadget draw-gadget*
[ { 10 10 } ] dip texture>> [ draw-texture ]
curry with-translation ;
! In the listener
"vocab:images/sprites/game_drop.png" gadget.
! the above works and shows the image in the listener
"vocab:images/sprites/game_drop.png" "i-gadget" open-window
! the above opens a new window but the image does not show
What could I be missing?
Thanks,
Sankar
