TYPO3 Core

There are already some places where ExtJS is used to display modal windows and there will be some more in the future (e.g. as a result from the workspaces team sprint in Wiesbaden).

Thus, two new static functions are defined and placed in backend.php.

TYPO3.Window
TYPO3.Dialog

Thus, every application can use windows and dialogs like e.g.
top.TYPO3.Window.getWindow({
title: 'Title',
html: 'Message',
id: 'cssId',
identifier: 'individualIdentifier',
});

and select it by the given identifier again, like e.g.
top.TYPO3.Window.getActiveWindow('individualIdentifier').close();

Dialogs can be shown for "information", "question", "error" and "warning" with e.g.
top.TYPO3.Window.getInformationDialog({
title: 'Title',
msg: 'Message'
});
