C#无框窗体的隐藏代码是啥？(类似QQ停靠桌面边缘自动隐藏)

Posted 2023-04-23

说明具体事件的用法

工具箱里去找 noti。。开头的控件！
QQ的边缘弹下来这一步：当鼠标触及边缘后，界面整体下移到这个界面出现为止；当鼠标离开界面后，界面会上移出屏幕，就实现了“隐藏”就是利用移动他实现隐藏！

参考技术A 停靠隐藏，自己做控件，或者去下载停靠隐藏控件，网上有 参考技术B 没做过，不过想来应该是响应Form 的 MouseEnter，MouseLeave 事件，改变Form状态。 参考技术C 正在学习C#，不清楚

C# winform 窗体左右一部分显示 一部分隐藏

就跟以前qq的那个什么代理一样，点一下显示出来。再点一下隐藏。新手麻烦稍微详细一点。谢谢

// 采用SplitContainer容器控件，可以实现QQ聊天窗口右侧边栏伸缩展开的效果。

if(splitContainer.Panel1Collapsed)

     splitContainer.Panel1Collapsed=false; // 展开
else

     splitContainer.Panel1Collapsed=true; // 收缩

参考技术A 在From窗体上，放2个panel控件，点击“隐藏”，将一个panel隐藏，将另一个panel显示，显示的那个panel重新设置它的大小追问

谢谢。我找到一个修改它大小的方法能用。 this.Width或者其他什么的来显示。

参考技术B Form1 frm = new Form1(); frm.Hide();窗体就隐藏
