Inheritance

[CAVESTER]

Hi Folks!

 

I am trying to do a simple thing here :rolleyes: Anyway, what I am trying to learn is the basic art of Inheritance and what I thought I'd like to achieve is... if I have say five forms in my app and I click a button on one of them I want all the forms to change color. Like when you change the colors in XP and all window frames change color. I had a go but unfortunatly not very successfully. Can someone point me in the right direction please?

 

Thanks,

 

Lee.

Not entirely sure inheritance is entirely the correct solution here. Also if you want to learn inheritance and OOP ideas in general then a more back to basics approach may be in order.

 

not .Net but worth a look : http://www.quiver.freeserve.co.uk/OOP1.htm

 

same again but also worth a look

What I would do is create a static Array that stores a reference to these five forms and create a static method that changes the color of each Form in the Array.

Wondered why it wasn't working, I did think however that changing the base form should change any derived forms but it didn't?
