Windows GUI更改按钮颜色 [英] Windows GUI change button color

问题描述

我想在用户点击它时更改按钮颜色。

主要计划是：每个月第10个工人的按钮变为红色，如果工人完成了他的工作，那么点击按钮它会变成绿色。

我不知道该怎么办。

我已经有了这个代码......我刚刚创建了一个窗口并添加了一个按钮：

I wanna change button colors when the user click on it.
The main plan is: every month 10th one worker's button go to red and if the worker done his job then click on the button and it going to be green.
I have no idea what to do.
I already have this code... I just created a window and add a button to it:

#include <windows.h>

LRESULT CALLBACK WindowProcedure(HWND,UINT,WPARAM,LPARAM);

void AddButton(HWND hwnd);


LRESULT CALLBACK WindowProcedure(HWND hWnd, UINT msg, WPARAM wp,
	LPARAM lp)
{
	switch (msg) {
	case WM_DESTROY:
		PostQuitMessage(0);
		break;
	case WM_CREATE:
		AddButton(hWnd);
		break;
	default:
		return DefWindowProcW(hWnd, msg, wp, lp);
	}
}

void AddButton(HWND hWnd)
{
	CreateWindowW(L"Button", L"Change colors", WS_VISIBLE | WS_CHILD,
		350, 200,
		100, 100,
		hWnd,
		NULL,
		NULL,
		NULL);
}

我的尝试：



所以我尝试了WM_LBUTTONDOWN ...所以我认为这是当用户点击按钮时程序会做的事情。我放入了开关（msg）案例WM_LBUTTONDOWN：

但不知道下一步是什么

What I have tried:

So I tried WM_LBUTTONDOWN... so i think this is something when the user click on the button the program will do something. i put in the switch(msg) case WM_LBUTTONDOWN:
but no idea what's next

您需要使用自定义绘图功能，请参阅< a href =https://docs.microsoft.com/en-gb/windows/desktop/Controls/buttons>按钮 - Windows应用程序| Microsoft Docs [ ^ ]。我建议首先更熟悉Windows控件的一般用法。自定义绘图是一个稍微高级的主题。

You need to use the custom draw feature, see Button - Windows applications | Microsoft Docs[^]. I would suggest getting more familiar with the general use of Windows controls first. Custom drawing is a slightly more advanced subject.
