Enable/Disable GLSL and keep it permanent?

[Gab]

I'm not talking about Settings.setEnableOpenGL(true);

I'm not sure if there's already and example on the forum about this but I would like to have a button that can enable/disable my plugin shader for the lower ends computer.

I had a simple solution that would have been hiding the Shader panel directly by making it invisible but I'm not sure if it will actually reduce the glsl impact on GPU.

And for making value permanent I'm not sure how to word it properly but basically I would like to have the button to be permanent so if the user click it the shader will be disabled when another instance of the plugin is loaded.

Thanks in advance!

@Gab For your first issue of enabling or disabling openGl, I think you need to use Settings.setEnableOpenGL(bool shouldBeEnabled) As far as I know this is the only way of enabling/disabling it. If your panel is hidden, it won't get processed but openGl can (I believe) still effect how other componens' graphics are being processed.

With regards to making the value permanent so the user doesn't need to reset it each time, I actually just wrote a script for doing just this. My example is a bit verbose for what you need but it will work nonetheless (it doesn't need to be written to JSON for instance, and you don't need an array here).

In this example the button state is dumped into a JSON file which I am saving in the expansions folder (AppData is a better location when you release the plugin). When the plugin is initialized the script will run and set the corresponding control callbacks to whatever state it is saved to. At the same time, toggling the button will update it's state.

Oh and if you load a Floating Tile with Custom Settings you can also enable/disable open gl from there.

@HISEnberg Thanks!!
