防止双击MFC对话框按钮 [英] Prevent double click on MFC-Dialog button

问题描述

我正在MFC C ++中开发Autocad/Bricscad对话框.知道我发现了一个更大的问题.有一个对话框为特殊"图形对象设置元数据.我使用此对话框(循环)更新每个特殊"图形对象的数据.因此，如果您有十个特殊"图形对象，则同一对话框将打开十次(成功).现在我有一个问题，用户有时会双击确定"按钮.但是，如果双击速度足够快，则该对话框下一个实例的确定"按钮将自动单击.我尝试了很多(例如，如果单击该按钮则禁用该按钮)，但是没有任何解决方法.也许你们当中有人有个好主意.

i'm developing Autocad/Bricscad-Dialogs in MFC C++. Know i detected a bigger problem. There is a dialog which sets metadata for 'special' drawing objects. I update the data of every 'special' drawing object with this dialog (in a loop). So if you have ten 'special' drawing objects, the same dialog will open ten times (successively). Now i have the problem that the user sometimes make a double click on the "OK"-Button. But if this double click is fast enough, the "OK"-Button of the next instance of this dialog will clicked automatically. I tried a lot (for example disabling the button if it was clicked) but nothing solved my problem. Maybe someone of you have a good idea.

最诚挚的问候， 西蒙

推荐答案

打开新对话框时，您可以在进入常规消息循环之前刷新鼠标单击消息的消息队列，例如:

When you open a new dialog you can flush the message queue of mouse click messages before going into your normal message loop, e.g.:

MSG msg;
while (PeekMessage(&msg, hWndDlg, WM_LBUTTONDOWN, WM_LBUTTONDOWN, PM_REMOVE));
