Re: Saving and loading presets for a gui

hi

not sure if this is the best solution but I do something like this

( // to save data
var data = Dictionary.new,
data.put("whatever", 333);
data.writeArchive("path/to/file/filename.txt");
)

( // to read data
var data = Object.readArchive("path/to/file/filename.txt");
data.keysValuesDo{ |key, value|
	[key, value].postln;
}
)


In the case of storing the state of a GUI I keep a dictionary containing 
key,instance for each of the widgets as I construct them

(
var w = Window.new.front;
var controls = Dictionary.new;
controls[\tremolo] = EZSlider( w,
	100@30,
	"freq",
	ControlSpec(0.001, 50, \lin, 0.001, 0.1),
	{ |ez| ez.value.postln }
);
)

then when I want to save the GUI state I loop the controls dict storing 
the key,value for each widget

(
var data = Dictionary.new,
controls.keysValuesDo { |key, widget|
	data.put(key, widget.value)
};
data.writeArchive("path/to/file/filename.txt");
)

and finally to restore the GUI to a particular state

(
var data = Object.readArchive("path/to/file/filename.txt");
data.keysValuesDo{ |key, value|
	{controls[key].valueAction = value}.defer
}
)

This code is just copy paste from a big project so I am not sure it runs 
properly but I guess you get the idea from it.
