[Octave-bug-tracker] [bug #35393] Switching figure toolkit with graphics_toolkit() closes figure

[Ben Abbott]

Follow-up Comment #1, bug #35393 (project octave):

Looking at graphics.h.in, I see there is no updater for the figure's
__graphics_toolkit__ property. So there is less than "an overly simple
listener" ;-)


3419       string_property xvisual , ""
3420       radio_property xvisualmode , "{auto}|manual"
3421       callback_property buttondownfcn , Matrix ()
3422       string_property __graphics_toolkit__ s , "gnuplot"
3423       any_property __guidata__ h , Matrix ()
3424     END_PROPERTIES


We can gell genprops.awk there is a custom updater by adding the "u"
qualifier.


3419       string_property xvisual , ""
3420       radio_property xvisualmode , "{auto}|manual"
3421       callback_property buttondownfcn , Matrix ()
3422       string_property __graphics_toolkit__ s u , "gnuplot"
3423       any_property __guidata__ h , Matrix ()
3424     END_PROPERTIES


Then we'll need to add the updater.


figure::properties::update___graphics_toolkit__ (void)
{
...
}


What should the updater do ?
