改变大小用Me.Width和Me.Height就行了,楼主想问的是允许用户改变无边框窗体的大小吧?
Public Class Form1
Private Declare Function GetWindowLong Lib "user32.dll" Alias "GetWindowLongA" (ByVal hwnd As Int32, ByVal nIndex As Int32) As Int32
Private Declare Function SetWindowLong Lib "user32.dll" Alias "SetWindowLongA" (ByVal hwnd As Int32, ByVal nIndex As Int32, ByVal dwNewLong As Int32) As Int32
Private Const GWL_STYLE As Int32 = -16
Private Const WS_THICKFRAME As Int32 = H40000
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.FormBorderStyle = Windows.Forms.FormBorderStyle.None
Dim style As Int32 = GetWindowLong(Me.Handle, GWL_STYLE) Or WS_THICKFRAME
SetWindowLong(Me.Handle, GWL_STYLE, style)
End Sub
End Class
以下代码添加到你需要触发的事件里:
1,把你的textbox的Multiline改成True(如果此处不修改你后面修改大小的时候只能修改width,而不能修改height),如果希望自动修改height,你的字体也要修改
2,添加这句代码(假设你要修改大小的textbox就是textbox1):
TextBox1.Location = New System.Drawing.Point(5, 20) '5, 20是你定义的针对窗体左上角点的X和Y位置
textbox1.size= New System.Drawing.Size(500, 600)‘500, 600是你自己定义的宽(width)和高(height)
3,或者直接写成:
TextBox1.Multiline = True’允许修改多行文本框
TextBox1.Location = New Point(5, 20) '5, 20是你定义的针对窗体左上角点的水平X和垂直Y位置
TextBox1.Size = New System.Drawing.Size(500, 600)‘500, 600是你自己定义的宽(width)和高(height)
1.在mouse事件中实现
2.调用windows API
实现方式为:
1.在mouse事件中实现
[csharp] view plain copy
Point mouseOff;//鼠标移动位置变量
bool leftFlag;//标签是否为左键
private void groupControl1_MouseUp(object sender, MouseEventArgs e)
{
if (leftFlag)
{
leftFlag = false;//释放鼠标后标注为false;
}
}
private void groupControl1_MouseMove(object sender, MouseEventArgs e)
{
if (leftFlag)
{
Point mouseSet = Control.MousePosition;
mouseSet.Offset(mouseOff.X, mouseOff.Y); //设置移动后的位置
Location = mouseSet;
}
}
private void groupControl1_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
mouseOff = new Point(-e.X, -e.Y); //得到变量的值
leftFlag = true; //点击左键按下时标注为true;
}
}
private void groupControl1_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
mouseOff = new Point(-e.X, -e.Y); //得到变量的值
leftFlag = true; //点击左键按下时标注为true;
}
}
2.调用windows API
调用前需要添加using System.Runtime.InteropServices;
[csharp] view plain copy
[DllImport("user32.dll")]
public static extern bool ReleaseCapture();
[DllImport("user32.dll")]
public static extern bool SendMessage(IntPtr hwnd, int wMsg, int wParam, int lParam);
private void groupControl1_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
ReleaseCapture(); //释放鼠标捕捉
//发送左键点击的消息至该窗体(标题栏)
SendMessage(Handle, 0xA1, 0x02, 0);
}
}
