如何查找窗口的 SW_SHOW/SW_HIDE 状态

how to find a window#39;s SW_SHOW/SW_HIDE status(如何查找窗口的 SW_SHOW/SW_HIDE 状态)

问题描述

我正在尝试确定已使用 CWnd::ShowWindow() 隐藏或启用的窗口控件的可见性.(或::ShowWindow(hWnd,nCmdShow))

I am trying to determine a window control's visibility that has been hidden or enabled with CWnd::ShowWindow(). (or ::ShowWindow(hWnd,nCmdShow))

我不能简单地使用 ::IsWindowVisible(hWnd)，因为控件位于选项卡上，它本身可能会被切换，导致 IsWindowVisible 返回 FALSE.

I cannot simply use ::IsWindowVisible(hWnd) as the control is on a tab sheet, which may itself be switched out, causing IsWindowVisible to return FALSE.

有没有办法获得 SW_SHOW/HIDE(或其他)窗口状态，还是我需要使用 ShowWindow() 的 retun 值并相应地重置?

Is there a way to get the SW_SHOW/HIDE (or others) window status or do I need to use the retun value of ShowWindow() and reset accordingly?

由于控件已启用(或禁用)以显示，但当前可能不可见，因为选项卡已切换，我认为它的 SW_SHOW 状态将保持不变，即使窗口本身实际上并未打开.如果我的期望是不现实的.

edit: as the control is enabled (or disabled) to show, but may not be currently visible, as the tab is switched ot, I would think that it's SW_SHOW status would remain the same, even if the window itself is not actually switched in. If I'm unrealistic in my expectations that that's fine.

所以我真的在寻找可以显示此窗口/控件吗"

So really I'm looking for 'can this window/control be shown'

推荐答案

使用GetWindowPlacement.它填充 WINDOWPLACEMENT 结构，其中有字段 <代码>showCmd.

Use GetWindowPlacement. It fills WINDOWPLACEMENT structure, which has field showCmd.

showCmd
指定窗口的当前显示状态.此成员可以是以下值之一.

showCmd
Specifies the current show state of the window. This member can be one of the following values.
