虽然Form类没有提供Minimize的事件,但还是可以通过重载Deactive来实现
当Form失去焦点后,测试WindowState取得Form状态,若为Minimized既是最小化事件。
本例为最小化后隐藏窗口:
private void Form1_Deactivate(object sender, EventArgs e) { if (this.WindowState == FormWindowState.Minimized) this.Visible = false; } 还有种方法更加直接,重载WndProc: const int WM_SYSCOMMAND = 0x112; const int SC_CLOSE = 0xF060; const int SC_MINIMIZE = 0xF020; const int SC_MAXIMIZE = 0xF030; protected override void WndProc(ref Message m) { if (m.Msg == WM_SYSCOMMAND) { if (m.WParam.ToInt32() == SC_MINIMIZE) { this.Visible = false; return; } } base.WndProc(ref m); } Resize 事件 private void Form1_Resize(object sender, System.EventArgs e) { if (this.WindowState == FormWindowState.Minimized) { // Write code here -- By TheAres } }
