使用RibbonPanelBreak创建Slide-Out Panel遇到的问题

[465340553]

Win7 简体中文版

Autocad civil 3d 2018简体中文版

Visual studio 2015社区版

C#语言

如下图，

使用RibbonPanelBreak分隔，

创建Slide-Out Panel（我不知道这个描述是否准确）。

按钮能够正常创建，

命令也能正常发送。

上图中的按钮“图形清理1”工作一切正常。

问题出在点击Slide-Out Panel部分的按钮时，

例如上图中的“图形清理2”（调用的map 3d的命令mapclean），

对话框弹出后，

如果此时autocad失去焦点，

比如切换到其他程序或者这桌面点击鼠标等，

弹出的对话框会“消失”，

从而造成AutoCAD被卡死。

我注意到AutoCAD自带的Ribbon，

其Slide-Out部分在鼠标点击后，

会慢慢消失，

而我创建的ribbon中的Slide-Out部分在鼠标点击并弹出对话框后，

它一直在那里（如下图），

直到对话框关闭，

最初发现此问题是我自己设计的对话框工作不正常，

以为自己的对话框语有问题，

折腾了很长时间，

后来对其他对话框进行测试，

发现位于Slide-Out部分的按钮弹出的对话框有问题，

才意识到问题不是出在对话框本身，

而是我创建的ribbon有问题。

我不清楚应该怎样修改我的代码，

麻烦指点一下。

谢谢！

下面是我的代码。

经过网友edata的测试，

我被搞的更晕了，

感觉问题远比想象的复杂。

增加两个autocad的命令进行测试，

style和insert，

发现style命令没有问题，

对话框弹出后，

滑出面板会消失，

对话框能正常工作，

但insert命令仍存在问题，

对话框弹出后，

滑出面板不消失，

autocad失去焦点后对话框消失，

autocad卡死。

下面是我增加button的代码：

 rrp.Items.Add(new RibbonRowBreak());
 rb = new RibbonButton();
 rb.Name = "样式";
 rb.ShowText = true;
 rb.Text = "样式";
 rb.CommandHandler = new RibbonbtnCmdHandle();
 rb.CommandParameter ="_.style ";

 rrp.Items.Add(rb);

 rrp.Items.Add(new RibbonRowBreak());

 rb = new RibbonButton();
 rb.Name = "插入";
 rb.ShowText = true;
 rb.Text = "插入";
 rb.CommandHandler = new RibbonbtnCmdHandle();
 rb.CommandParameter ="_.insert ";

 rrp.Items.Add(rb);

补充：

如果把滑出面板钉住，

对话框就不会消失。

网友edata帮我解决了问题，

切换了一下焦点，

问题解决！

在此向edata表示感谢！

You probably already know: for recent versions of AutoCAD (Acad2014, or 2015 and later), You can simply call

Application.MainWindow.Focus()

instead of Autodesk.AutoCAD.Internal.Utils.SetFocusToDwgView() (I guess Autodesk just added this functionality from Internal namespace to Application class).

谢谢！

我试试看！
