您如何知道工具栏的停靠状态已更改 [英] How do you know when the docking state of a toolbar has changed

问题描述

有人问了类似的问题@ 检测CControlBar对接的时间状态已更改，但是答案是从控件的角度编写的.我想知道对接状态何时从CFrameWnd更改，因为我有一个窗口填充了工作区，只要对接状态发生变化，就需要重新定位该客户区.我当前的WM_SIZE代码有效，但是如果工具栏停靠或取消停靠，则无效.

Someone asked a similar question @ Detecting when a CControlBar's docking state has changed, but the answer is written from the standpoint of the control. I want to know when the docking state changes from CFrameWnd, because I have a window filling up the client area that needs to be repositioned whenever the docking state changes. My current WM_SIZE code works, but not if a toolbar is docked or undocked.

推荐答案

您可以覆盖CFrameWndEx的AdjustDockingLayout功能. 每次更改对接布局时都会调用它.

You could override the AdjustDockingLayout function of CFrameWndEx. It will be called every time docking layout is changed.

MSDN信息:

注意: 在创建停靠窗口期间，有多次对此功能的调用(您可能希望忽略它们).

Note: During the creation of the Docking windows, there are multiple calls to this function (you might want to ignore them).

void CMainFrame::AdjustDockingLayout(HDWP hdwp)
{
    CMDIFrameWndEx::AdjustDockingLayout(hdwp);

    // do some calulations
}
