Change components properties in large scale

Question

I have a reasonable amount of components attached to a window. I want to change some properties of these components when a button is pressed. But do this in one component at a time is a boring job and will involve many lines of code. It is possible to make a component to listen the other component signal to perform a task when the signal is released? That is, something like the observer pattern. If this is not possible. What would be the best way to do a mass change of these components? Example: Code UI And if I want to reset all the other components to the initial state when the "Reset" button is triggered? Create a handler to the button signal and change the components (Entries, Switches, CheckBose, ...) one at a time is very tiring JavaScript questions and answers, JavaScript questions pdf, JavaScript question bank, JavaScript questions and answers pdf, mcq on JavaScript pdf, JavaScript questions and solutions, JavaScript mcq Test , Interview JavaScript questions, JavaScript Questions for Interview, JavaScript MCQ (Multiple Choice Questions)

Answer 1

This may not be the answer you wanted but... You are probably optimizing in the wrong place. The window in your example takes about 6 lines of very straight-forward code to 'reset'. This is insignificant compared to the benefits of the solution: the code is very easy to understand later on it's also easy to modify later on (when e.g. a default value changes) These are far more important things than the two minutes you spend on writing the code originally -- and this is unlikely to change even if you make the form more complex (although I would question the basic design if you end up with a screen full of GtkEntries).
