我有一个类来处理一种用户控件弹出窗口,它通过继承System.Windows.Forms.ToolStripDropDown来工作。这对我目前的弹出类型有用,我将在下面详述;
首先,是用于以弹出类型样式保存用户控件的类;
public class PopupWindow : System.Windows.Forms.ToolStripDropDown
{
private System.Windows.Forms.Control _content;
private System.Windows.Forms.ToolStripControlHost _host;
public PopupWindow(System.Windows.Forms.Control content)
{
//Basic setup...
this.AutoSize = false;
this.DoubleBuffered = true;
this.ResizeRedraw = true;
this.BackColor = content.BackColor;
this._content = content;
this._host = new System.Windows.Forms.ToolStripControlHost(content);
//Positioning and Sizing
this.MinimumSize = content.MinimumSize;
this.MaximumSize = content.Size;
this.Size = content.Size;
content.Location = Point.Empty;
//Add the host to the list
this.Items.Add(this._host);
}
}
正如我们在这里看到的,我只是将控件传递给它,并让它完成工作。在“onclick”弹出窗口中使用它时,就像这样,它工作正常;
public void Popup(object sender, MouseEventArgs e, other params)
{
DevicePopup popupDevice = new DevicePopup();
//do stuff to the control here before displaying
PopupWindow popup = new PopupWindow(popupDevice);
popup.Show(Cursor.Position);
}
并像这样调用它;
this.Controls[btnAdd.Name].MouseClick += (sender, e) =>
{
int index = temp;
generatePopup.Popup(sender, e, mDevices[index], this);
};
按照预期成功执行此操作会在鼠标单击时创建弹出式用户控件。
然而,我现在正在尝试使用第二种类型的弹出窗口,当出现问题时会产生弹出窗口。下面是我的新弹出类,并调用它;
public void AlarmNotificationPopup(IDeviceInterface device)
{
try
{
AlarmNotification ANotification = new AlarmNotification();
//do stuff to the control again before displaying
PopupWindow popup = new PopupWindow(ANotification);
popup.Show(100, 100);
}
catch (Exception e)
{
MessageBox.Show(e.Message);
}
}
AlarmNotificationPopup(device);
但是,这个弹出窗口没有正确渲染/创建,看起来像这样;
我不完全确定如何解决这个问题。有人有什么想法吗?

要尝试的几件事情:
我认为您不需要“基本设置”,因此请注释掉。另外,尝试设置边距和填充:
public PopupWindow(Control content) {
// Basic setup...
// this.AutoSize = false;
// this.DoubleBuffered = true;
// this.ResizeRedraw = true;
// this.BackColor = content.BackColor;
this._content = content;
this._host = new ToolStripControlHost(content);
this._host.Margin = new Padding(0);
this._host.Padding = new Padding(0);
this.Padding = new Padding(0);
this.Margin = new Padding(0);
//Positioning and Sizing
this.MinimumSize = content.MinimumSize;
this.MaximumSize = content.Size;
this.Size = content.Size;
content.Location = Point.Empty;
//Add the host to the list
this.Items.Add(this._host);
}
确保您的AlarmNotification
设置了MinimumSize
属性。
如果这无法解决问题,那么您可能需要记录AlarmNotification
类正在做什么。
