Error using matlab.gra​phics.Grap​hics/set The name 'handlevisibility' is not an accessible property for an instance of class 'matlab.gr​aphics.Gra​phicsPlace​holder'.

When I use the command

set(aaa.uic3(:),'handlevisibility','callback')

the error message appears:

Error using matlab.graphics.Graphics/set

The name 'handlevisibility' is not an accessible property for an instance of class 'matlab.graphics.GraphicsPlaceholder'.

Any ideas what is wrong?

[Geoff Hayes]

Victor - what object types do the handles in the aaa.uic3 array correspond to? Perhaps at least one does not have the HandleVisibility property?

[Victor Popov]

Geoff, the part of code below. Where is my error?

[Tommy]

Similar to how

a(3) = true

fills a(1) and a(2) with false, your SkMp.uic3 (which is a 4x9 Graphics array) fills empty values with GraphicsPlaceholder objects. One option is to store your graphics objects some other way, like with a cell array, to avoid allocating space that you don't need and don't use.

Another option is to loop through the array and check whether 'HandleVisibility' is a property of each element:

for i = 1:numel(SkMp.uic3)
    if isprop(SkMp.uic3(i), 'HandleVisibility')
        set(SkMp.uic3(i),'handlevisibility','callback')
    end
end

Thanks so much for the valuable advice. I will definitely use them.

Answer 2

[Walter Roberson]

valobj = findobj(SkMp.uic3(:), 'flat', '-property', 'handlevisibility');
set(valobj, 'handlevisibility', 'callback')
