如何使用CreateWindowEx为窗口设置自定义颜色 [英] How to set custom color for window using CreateWindowEx

问题描述

我创建了这样的窗口。我需要设置窗口的红色，例如：

 WNDCLASSEX MyClassStruct; 
  const   char  MyClassName [] =   MyClass; 
 MyClassStruct.style = CS_HREDRAW | CS_VREDRAW; 
 MyClassStruct.cbSize =  sizeof （WNDCLASSEX）; 
 MyClassStruct.lpfnWndProc = MyWndProc; 
 MyClassStruct.cbClsExtra =  0 ; 
 MyClassStruct.cbWndExtra =  0 ; 
 MyClassStruct.hInstance = hInstance; 
 MyClassStruct.hIcon = NULL; 
 MyClassStruct.hCursor = LoadCursor（NULL，IDC_ARROW）; 
 HBRUSH redbru = CreateSolidBrush（RGB（ 255 ， 0 ， 0 ））; 
 MyClassStruct.hbrBackground = redbru; 
 MyClassStruct.lpszMenuName = NULL; 
 MyClassStruct.lpszClassName = MyClassName; 
 
 RegisterClassEx（& MyClassStruct）; 
 
 
 CtrlsWnd = CreateWindowEx（WS_EX_TOPMOST，MyClassName，TEXT（  title），WS_VISIBLE， 0 ， 0 ， 200 ，
  100 ，NULL，NULL，hInstance，NULL）; 

但结果是新创建的窗口有标准颜色 - COLOR_WINDOW。

为什么没有设置红色背景？

解决方案

谢谢大家的帮助！我解决了这个问题。问题出在垃圾中，这是在窗口程序中写的。我清理并修理了它。它完美无缺。

您将 redbru 分配给 ButClassStruct .hbrBackground 当您将 MyClassStruct 传递给 CreateWindowEx 时。

I created the window something like this. And I need to set the red color of the window, for example:

WNDCLASSEX MyClassStruct;
const char MyClassName[] = "MyClass";
MyClassStruct.style = CS_HREDRAW | CS_VREDRAW;
MyClassStruct.cbSize = sizeof(WNDCLASSEX);
MyClassStruct.lpfnWndProc = MyWndProc;
MyClassStruct.cbClsExtra = 0;
MyClassStruct.cbWndExtra = 0;
MyClassStruct.hInstance = hInstance;
MyClassStruct.hIcon = NULL;
MyClassStruct.hCursor = LoadCursor(NULL, IDC_ARROW);
HBRUSH redbru = CreateSolidBrush(RGB(255,0,0));
MyClassStruct.hbrBackground=redbru;
MyClassStruct.lpszMenuName = NULL;
MyClassStruct.lpszClassName = MyClassName;

RegisterClassEx (&MyClassStruct);


CtrlsWnd = CreateWindowEx(WS_EX_TOPMOST,MyClassName,TEXT("title"),WS_VISIBLE,0,0,200,
100,NULL,NULL,hInstance,NULL);

But as a result the newly created window has standard color - COLOR_WINDOW.
Why does not red background set up?

解决方案

Thank you all for your help! I solved the problem. The problem was in the garbage, which was written in the window procedure. I cleaned and fixed it. And it works perfectly.

You are assigning redbru to ButClassStruct.hbrBackground while you are passing MyClassStruct to the CreateWindowEx call.
