Hi,
is it possible to return "synchronously" even if I have an asynchronous message?
For example:
SomeObject>>someMethod ^ UIManager default chooseFrom: #(a b c)
When the above method is executed, it will open a popup and block the execution until I select something, then it will return the selection.
But if I instead have something like this
SomeObject>>otherMethod |choice| NewListModel new items: #(a b c); whenSelectedItemChanged: [ :item | choice := item ]; openDialogWithSpec. choice.
Then it will open the window but it will immediately return nil.
With a spec window, you can try to open it modal WindowModel>>#modalRelativeTo: aWindow
NewListModel new ... openDialogWithSpec modalRelativeTo: self currentWorld. Thanks! Peter
