(转)C# WinForm 关于窗体最大化时的是否全屏效果与是否遮盖任务栏
0.新建窗体 及添加按钮
1. 执行如下按钮事件
private void btnFormMax_Click(object sender, EventArgs e) { if (this.WindowState == FormWindowState.Maximized) { this.WindowState = FormWindowState.Normal; } else { this.WindowState = FormWindowState.Maximized; } }
窗体最大化时 非全屏 不会遮盖任务栏
此时this.FormBorderStyle 默认为 Sizable
2. 执行如下按钮事件
private void btnFormMax_Click(object sender, EventArgs e) { if (this.WindowState == FormWindowState.Maximized) { this.WindowState = FormWindowState.Normal; } else { this.FormBorderStyle = FormBorderStyle.None; this.WindowState = FormWindowState.Maximized; } }
窗体最大化时 会全屏 及遮盖任务栏
此时this.FormBorderStyle 为 None 不会显示窗体标题栏等相关
3. 执行如下按钮事件
private void btnFormMax_Click(object sender, EventArgs e) { if (this.WindowState == FormWindowState.Maximized) { this.WindowState = FormWindowState.Normal; } else { this.FormBorderStyle = FormBorderStyle.None; this.MaximumSize = new Size(Screen.PrimaryScreen.WorkingArea.Width, Screen.PrimaryScreen.WorkingArea.Height); this.WindowState = FormWindowState.Maximized; } }
窗体最大化时 非全屏 不会遮盖任务栏
此时this.FormBorderStyle 为 None 不会显示窗体标题栏等相关
[转]窗体最大化的时候,如何指定窗体的位置、大小(C#)
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; namespace WindowsApplication1 { public partial class FormRegion : Form { private const long WM_GETMINMAXINFO = 0x24; public struct POINTAPI { public int x; public int y; } public struct MINMAXINFO { public POINTAPI ptReserved; public POINTAPI ptMaxSize; public POINTAPI ptMaxPosition; public POINTAPI ptMinTrackSize; public POINTAPI ptMaxTrackSize; } public FormRegion() { InitializeComponent(); this.MaximumSize = new Size(Screen.PrimaryScreen.WorkingArea.Width, Screen.PrimaryScreen.WorkingArea.Height); } protected override void WndProc(ref System.Windows.Forms.Message m) { base.WndProc(ref m); if (m.Msg == WM_GETMINMAXINFO) { MINMAXINFO mmi = (MINMAXINFO)m.GetLParam(typeof(MINMAXINFO)); mmi.ptMinTrackSize.x = this.MinimumSize.Width; mmi.ptMinTrackSize.y = this.MinimumSize.Height; if (this.MaximumSize.Width != 0 || this.MaximumSize.Height != 0) { mmi.ptMaxTrackSize.x = this.MaximumSize.Width; mmi.ptMaxTrackSize.y = this.MaximumSize.Height; } mmi.ptMaxPosition.x = 1; mmi.ptMaxPosition.y = 1; System.Runtime.InteropServices.Marshal.StructureToPtr(mmi, m.LParam, true); } } } }
MessageBox.Show("当前窗体标题栏高度"+(this.Height - this.ClientRectangle.Height).ToString());//获得当前窗体标题栏高度
ClientRectangle//获取表示控件的工作区的矩形
MessageBox.Show(SystemInformation.PrimaryMonitorSize.ToString()); //获取主显示器屏幕的尺寸(像素)
//获取主显示器当前当前视频模式的尺寸(以象素为单位)
MessageBox.Show("菜单栏高度"+SystemInformation.MenuHeight.ToString()); //获取标准菜单栏的高度
MessageBox.Show("标题栏高度"+SystemInformation.CaptionHeight.ToString()); //获取标准标题栏的高度
MenuHeight//获取一个菜单行的高度(以象素为单位)
CaptionHeight//获取窗口的标准标题栏区域的高度(以象素为单位)
