比方说,我希望表格的大小为100x100,然后在1秒后为200x200,我该怎么做?运行表单后,我是否要更新大小?设置大小后再使用Thread.Sleep(),然后设置新大小吗?我真的很困惑如何做到这一点。最终,我希望在屏幕上有一个位图,该位图将由箭头键控制。但是只是为了让我更好地了解如何使下面的代码正常工作?
open System
open System.Drawing
open System.Windows.Forms
open System.Threading
let form = new Form()
form.Size <- new Size(100, 100)
Thread.Sleep(1000)
form.Size <- new Size(200, 200) // ???
do Application.Run form
第二次尝试
open System
open System.Drawing
open System.Windows.Forms
let form = new Form()
form.Size <- new Size(100, 100)
do Application.Run form
let timer = new Timer()
timer.Interval <- 1000
timer.Start()
form.Size <- new Size(200, 200)
答案 0 :(得分:0)
这是一种实现方法:
open System
open System.Drawing
open System.Windows.Forms
open System.Threading
let form = new Form()
form.Size <- new Size(100, 100)
async {
do! Async.Sleep 1000
form.Size <- new Size(200, 200)
} |> Async.Start
do Application.Run form
