我使用下面的代码移动窗体的窗体,移动工作正常,但问题是不透明和关闭。我想这样做:当我按下按钮不透明度= 0.5时,当我向上按钮不透明度= 1时,当左侧按钮向下时,我也移动鼠标窗口移动,当我只点击窗体,然后窗体必须关闭。移动窗口的问题
using System;
using System.Runtime.InteropServices;
using System.Windows.Forms;
public partial class FormImage : Form {
public const int WM_NCLBUTTONDOWN = 0xA1;
public const int HT_CAPTION = 0x2;
[DllImportAttribute("user32.dll")]
public static extern int SendMessage(IntPtr hWnd,
int Msg, int wParam, int lParam);
[DllImportAttribute("user32.dll")]
public static extern bool ReleaseCapture();
public FormImage() {
InitializeComponent();
}
private void FormZdjecie_MouseMove(object sender, MouseEventArgs e) {
if (e.Button == MouseButtons.Left) {
ReleaseCapture();
SendMessage(Handle, WM_NCLBUTTONDOWN, HT_CAPTION, 6);
}
}
private void FormImage_MouseDown(object sender, MouseEventArgs e) {
this.Opacity = 0.5;
}
private void FormImage_MouseUp(object sender, MouseEventArgs e) {
this.Opacity = 1;
}
private void FormImage_MouseClick(object sender, MouseEventArgs e) {
Close();
}
}
任何想法如何修复此代码?
