Question

我有图片盒的问题。我正在创建游戏启动器，当我点击图片框（按钮的角色）时，我想将表格背景图像更改为不同的图像。没关系，但是图片框有透明的背景颜色，所以图片框的背景依赖于Form bg图像。这是我的问题 - 图片框的背景更改晚于Form bg img。

我该如何解决这个问题？

我建议使用SuspendLayout（）和ResumeLayout（）暂时挂起布局以自绘图。我不确定你的语言是什么，但这是一个例子：

private void novinky_Click(object sender, EventArgs e)
    {
        this.SuspendLayout();

        domu.Visible = true;
        domu_clicked.Visible = false;
        novinky.Visible = false;
        this.BackgroundImage = posteruslauncher.Properties.Resources.background_novinky;

        this.ResumeLayout();

    }

表格背景图片更改 - ＆gt;图片框后来显示变化
