避免应用程序激活和在单击按钮上时的重点 - Windows API或Qt [英] Avoid application activation and focus in when clicking buttons on it - Windows API or Qt

问题描述

情况：无边框的QDialog在其他应用程序之上保持成功。

问题是当点击这个总是在顶层的应用程序窗口时，以下

• 点击的始终在线的应用程序已激活






有可能当点击这个总是在顶部的应用程序窗口时，无效和未聚焦的应用程序窗口，






• 当前应用程序不会松动激活和聚焦


• 仍然能够与始终在顶的应用程序交互（点击按钮或下拉菜单，拖动窗口）？






我正在使用Qt，但使用本机Windows API没有问题。





我试过下面的Qt windowFlag：






• Qt :: WindowDoesNotAcceptFocus 但不起作用：始终在顶的应用程序已激活，集中。


• Qt :: WindowTransparentForInput ，始终在顶应用程序对点击是真的透明的：未激活和不专注，但不幸的是，
使用Windows标志（ #include< qt_windows.h> ）。在创建并显示窗口后，必须使用以下内容：

  HWND winHandle =（HWND）winId 
 ShowWindow（winHandle，SW_HIDE）; 
 SetWindowLong（winHandle，GWL_EXSTYLE，GetWindowLong（winHandle，GWL_EXSTYLE）
 | WS_EX_NOACTIVATE | WS_EX_APPWINDOW）; 
 ShowWindow（winHandle，SW_SHOW）; 
  




Situation: A border-less QDialog stays successfully on top of other applications.

The problem is when clicking on this always-on-top application window, the following occurs:

• The clicked always-on-top application gets activated
• The clicked always-on-top application window steals the focus of previous active/focused app

Is there a possibility that when clicking on this always-on-top inactive and unfocused application window,

• the current application does not loose activation and focus
• while user being still able to interact with the always-on-top application (hitting buttons or drop-down menus, dragging the window)?

I'm working with Qt but there's no problem about using native Windows API.

I tried the following Qt windowFlag:

• Qt::WindowDoesNotAcceptFocus but it does not work: the always-on-top application is activated, focused.
• Qt::WindowTransparentForInput, the always-on-top application is really transparent to clicks: not activated and not focused in but buttons are unfortunately not triggered when hit.

解决方案

It is possible to make a window unactivable and unfocusable when clicking on it by using Windows flags (#include <qt_windows.h>). The following has to be used after the window is created and shown:

HWND winHandle = (HWND)winId();
ShowWindow(winHandle, SW_HIDE);
SetWindowLong(winHandle, GWL_EXSTYLE, GetWindowLong(winHandle, GWL_EXSTYLE)
    | WS_EX_NOACTIVATE | WS_EX_APPWINDOW);
ShowWindow(winHandle, SW_SHOW);
