Demo Restart Window (sorta reopen)
|
|
|
|
Once a window is closed, you can't do anything with it. You can't read it. You can't "re-open" it.
|
|
The only choice is to recreate the window. It's important that you use a "Fresh Layout" every time.
|
|
You can't pass the same layout from one indow to another. You will get a popup error infomrning you
|
|
that you've attempted to resuse a layout.
|
|
|
|
The purpose of this demo is to show you the simple "make window" design pattern. It simply makes a
|
|
window using a layout that's defined in that function and returns the Window object. It's not a bad
|
|
way to encapsulate windows if your applcation is gettinga little larger than the typical small data
|
|
entry window.
