How to properly open a new window or switch between windows from code?

[paulorb]

I am creating a very simple (Desktop) application which consists in two Windows A and B.

A contains a button which when pressed should close the current window and open a new window B B only has a Text (label)

How can I properly manage the window creation/termination directly from the Compose/Window code.

What do you suggest? I saw some articles about Decompose, but I was looking for something more simple (since my application will have few windows)

I advice you to close this issue and post this type of question in stackoverflow or in the kotlin slack channel. Here, it will just create noise, since this is not an issue but a question on how to use a specific feature of the framework. Back to your question, you can have a list of WindowState in your Application and render the list all the time.

for (windowState in activeWindowsState) {
            key(windowState) {
                YourWindowCustomClass(windowState)
            }
        }

Then on the A button click you add WindowStateB to the list and remove WindowStateA from the windowstate list.

Check this windowState

Here is an example of similar functionality. Although it has some decoration on it: https://github.com/pablichjenkov/templato/blob/3ce5cd172f1bdc115addfefad60e139d61d021c9/component/desktopApp/src/jvmMain/kotlin/com/pablichj/incubator/uistate3/demo/DesktopAppNode.kt#L9
