Force redraw - how?

[pztrn]

How to force window redraw, e.g. from another goroutine?

[runrc]

Use imgui.Refresh() to schedule a refresh from the main thread or any goroutine.

// Automatically refresh the GUI main window every 500 millisecond using a ticker.
refreshTicker := time.NewTicker(500 * time.Millisecond)
refreshTickerDone := make(chan bool)

...

go func() {
  for {
    select {
      case <-refreshTickerDone:
        return
      case <-refreshTicker.C:
        imgui.Refresh()
    }
  }
}()

...

// Stop refresh ticker.
refreshTicker.Stop()
refreshTickerDone <- true
