Tracking window state

Describe the solution you'd like

Hi y'all! I want to track the WindowState in react, but it seems there is no event for it?

I tried EventsOn(":wails:window:maximised") like in the PR, and EventsOn(":wails:WindowIsMaximised") but neither of them fire when the WindowState changes.

On a side note: Is there any documentation for the events from the wails runtime? If not, do we need some? Where can I find these events? (CTRL+F :wails: I assume :P)

Hey thanks for opening this. There's already some window state methods available in the runtime library but I think we could do better here. Fancy a stab at it? 😅

[merlindru]

Yes! @leaanthony However, I can't let my frontend know when the window state changed with what's currently available in the runtime, right?

I want to change the state of my maximize button depending on whether the window is currently maximized or not:

Window is maximised

Window is normal

This is useful not only for frameless app's title bars, but for changing layout depending on the window state. My app can't know whether it's been maximised after the initial load without polling WindowIsMaximised

I want to change the state of my maximize button depending on whether the window is currently maximized or not:

Window is maximised

Window is normal

this could easily be achieved by adding an event listener on the resize event for the window and check for the window state after and update the UI accordingly.
