Will using multiple Window.SetContent in fyne api cause performance issues

In fyne API, will using multiple Window.SetContent cause performance issues? This is a problem that many developers often encounter when using the fyne framework. PHP editor Xigua will answer it for you. First, we need to understand the role of Window.SetContent. It is used to add content to the window, which can be a single control or a layout. When multiple Window.SetContents are used frequently in a window, it will indeed have a certain impact on performance. Each call to Window.SetContent will cause the window to be re-rendered, thus consuming a certain amount of computing resources. Therefore, in order to improve performance, we can consider combining multiple controls or layouts into a whole, and then use Window.SetContent once to add them to the window. This reduces the number of window re-renders, thereby improving performance. Of course, the specific impact also depends on the number and complexity of controls in the window, so in actual use, we need to make trade-offs and optimizations according to the situation.

Question content

I am developing an application but I need to use multiple window.setcontent methods of fyne api but I am worried that it will reduce the performance of my application. Is the oldest window.setcontent still running in the background? Or it stops working after I call the second window.setcontent method. This is the test code, in my real application I need to use the window.setcontent method more than the test code. I still haven't found a solution to make my application available without using the second window.setcontent method in the test code.

package main

import (
    "fyne.io/fyne/v2"
    "fyne.io/fyne/v2/app"
    "fyne.io/fyne/v2/widget"
)

func main() {
    a := app.New()
    
    w := a.NewWindow("testing")
    
    w.Resize(fyne.NewSize(400, 400))
    
    testButton1 := widget.NewButton("test1", func(){})
    
    testButton2 := widget.NewButton("go to test1 button", func(){
        w.SetContent(testButton1)
    })
    
    w.SetContent(testButton2)
    
    w.ShowAndRun()
    
}

Workaround

Setting the window content has to check if it fits and other things that can be slow. It might be more efficient to use a container and replace its contents.

It's also easier to make reusable components, since widgets shouldn't require them to use the entire window.
