如何在Devexpress中使用代码折叠/展开功能区? [英] How to collapse/expand ribbon using code in Devexpress?

问题描述

我正在使用DevX的Ribbon接口构建csharp应用程序，并且在通过代码折叠/扩展Ribbon控件时遇到麻烦，看来我们只能通过单击折叠/扩展"按钮来做到这一点.您能否给我一些有关如何通过代码实现该想法的想法?我已经使用Google搜索了几个小时而没有找到任何内容.
非常感谢！

I am building a csharp application using Ribbon Interface of DevX and I have a trouble with collapsing/expanding the Ribbon control by code, it seems that we can only do that by clicking on the Collapse/Expand button. Could you please give me some idea on how to achieve that by code? I have searched using Google for hours without finding anything.
Thank you so much!

推荐答案

RibbonControl.Minimized = true ???????? oO

what about RibbonControl.Minimized = true ????? oO

再一次，我为自己找到了解决方案！

我已经尝试了多种方法来实现自己想要的目标，但这确实并不简单.
最后，我必须使用PostMessage将WM_LBUTTONDOWN和WM_LBUTTONUP消息发送到要单击的点(此点必须在展开/折叠"按钮的区域内).这个小按钮没有任何所谓的HANDLE，但是它属于功能区控件.如果有手柄，我可以使用代码更轻松地单击它.现在，我们所需要做的就是计算该按钮区域内的点.我已经尝试过了，并且效果很好，但是不确定是否有任何情况不起作用.

代码如下:
声明WinAPI函数WindowFromPoint，GetWindowRect，PostMessage后:

Once again, I have found the solution for myself!

I have tried many ways to achieve what I want but it was really not simple.
At last, I had to use PostMessage to send WM_LBUTTONDOWN and WM_LBUTTONUP messages to the point I want to click (this point must be within the region of Expand/Collapse button). This small button doesn''t have any so-called HANDLE, but it is belong to ribbon control. If it had a handle, I could make a click on it using code more easily. Now, all we need is to calculate the point which is within that button''s region. I have tried this and it works well, but not sure if there may be any case it doesn''t work.

Here''s the code:
After declaring the WinAPI functions WindowFromPoint, GetWindowRect, PostMessage:

int x = ribbon.Width - 10;
IntPtr h = WindowFromPoint(Left + 1, Top + 1);
RECT rect;
GetWindowRect(h, out rect);
int y = rect.bottom - rect.top - 5;
PostMessage(ribbon.Handle, 0x201, 0, x + (y <<16));
PostMessage(ribbon.Handle, 0x202, 0, x + (y <<16));

只需单击展开/使用代码折叠按钮.当然，如果它是不可见的，我仍然不知道该怎么做.

That''s all to click on the Expand/ Collapse button using code. Of course if it''s invisible, I have still not found out how to do.

通过设置Ribbon.Minimized = true，您可以折叠分类目录

{
Ribbon.Minimized = true;
}

By setting Ribbon.Minimized = true you can collapse the cattogary


Public void CollapseMenu()
{
Ribbon.Minimized = true ;
}
