Allow to start a plugin just once

[niccah]

I'm wondering, that I can't find a nice solution, to allow to start a plugin just once.

So, with the help of my plugin, I start a WebDialog... How I can ask, if there is the same WebDialog already opened?

I think, this should be very easy, but, sorry...

I tried:

if (!defined? dlg) dlg = UI::WebDialog.... else dlg.bring_to_front

But with this version, I am able to start several WebDialogs...

Thanks for your help!

Assuming your code is wrapped inside a method inside a module... then referring to the web-dialog like this will use the same object IF it already exists, and if it doesn't it makes a new one...
@dlg = UI::WebDialog.new(...) unless @dlg
Then later use @dlg to change its url, show it etc, and set/reset all other options available etc...

Sometimes, it is so easy!

This is important!

The dialog instance is not destroyed when you close it. You can re-open it again.
And if you had data from the dialog, stored in Ruby vars, you can reset them back into the dialog's Javascript vars, after it reopens.
