Greetings All,
Has REALbasic developed a variable that can be used to hold a
reference to a Window?
I asked this about a year ago as it seemed to me that such a
capability would be beneficial for creating reusable objects;
instead of having to hardwire in a window reference you established
the variable as a property and then loaded that property with
whatever window you wanted to refer to.
Happy New Year....
As described above, this has always been possible and is commonly
done. Perhaps you're suggesting a new wrinkle that I'm not grasping:
Add a property to Window2, for example: MyWindow as Window1
Then initialize it as you wish, for example:
MyWindow = new Window1 // MyWindow now holds a ref to Window1
Then you can access Window1 elements within Window2 as:
self.MyWindow.Whatever.
Or, from outside Window2 as: Window2.MyWindow.Whatever
If you want a more generic property, dim the property in Window2 as:
MyWindow as Window
You can assign any Window instance to MyWindow, and access any
element of the Window as for example:
MyWindow.Top = 5
But if you want access to a unique element that you have added to
say, Window1, then you need to cast MyWindow to a Window1:
If MyWindow IsA Window1 then
Window1(MyWindow).MyWindow1Method
End
Best,
Jack
