在WM_MOUSEFIRST上找不到任何文档 [英] Can't find any documentation on WM_MOUSEFIRST

问题描述

我有我的自定义WndProc，它应该根据我的ImGui菜单是否打开来处理输入.

I have my custom WndProc which is supposed to handle input depending on if my ImGui menu is open.

if (Menu::isOpen) {
    ImGui_ImplWin32_WndProcHandler(hWnd, msg, wParam, lParam);
    if    (msg == WM_LBUTTONDOWN
        || msg == WM_LBUTTONUP
        || msg == WM_LBUTTONDBLCLK

        || msg == WM_MBUTTONDOWN
        || msg == WM_MBUTTONUP
        || msg == WM_MBUTTONDBLCLK

        || msg == WM_RBUTTONDOWN
        || msg == WM_RBUTTONUP
        || msg == WM_RBUTTONDBLCLK

        || msg == WM_XBUTTONDOWN
        || msg == WM_XBUTTONUP
        || msg == WM_XBUTTONDBLCLK
        || msg == WM_MOUSEFIRST) return 0;
}
return CallWindowProc((WNDPROC)Get().m_ulOldWndProc, hWnd, msg, wParam, lParam);

我的目标是在打开ImGui的情况下，仅防止鼠标单击进入背景.我注意到，如果我不阻止WM_MOUSEFIRST进行，某些点击仍然偶尔会在应用程序中注册.我还注意到，当我确实阻止执行WM_MOUSEFIRST时，将鼠标悬停在应用程序中的内容上是行不通的，这是我想要的.我以为可以通过检查wParams或lParams中的内容来解决此问题，但是我找不到有关WM_MOUSEFIRST的任何文档

My goal is to prevent ONLY mouse clicks from going to the background if my ImGui is open. I noticed that if I don't prevent WM_MOUSEFIRST from going through, some clicks still occasionally register in the app. I've also noticed that when I do prevent WM_MOUSEFIRST from going through, hovering over stuff in the application doesn't work, which I would like to. I thought that I could fix the problem by checking for something in the wParams or lParams, but I can't find any documentation on those for WM_MOUSEFIRST

推荐答案

粉碎鼠标后，我发现只有在鼠标移动时点击才会注册.这是因为应用程序检查WM_MOUSEMOVE(与WM_MOUSEFIRST相同)是否设置了wParam MK_LBUTTON.我只是添加了. ||((msg == WM_MOUSEMOVE)&&(wParam！= 0))

After smashing my mouse I found out that the click only registers if the mouse is moving. It was because the application checked if WM_MOUSEMOVE (which is same as WM_MOUSEFIRST) had the wParam MK_LBUTTON set. I simply added. || ((msg == WM_MOUSEMOVE) && (wParam != 0))
