如何更改按钮上的光标？ [英] How to change the cursor on a Button?

问题描述

static HWND btn;
HCURSOR cursor = LoadCursor(0, IDC_CROSS);

case WM_CREATE:
    btn = CreateWindow(TEXT("BUTTON"), TEXT("Press Me"),
                       WS_CHILD|WS_VISIBLE, 50, 50, 80, 30,
                       hwnd, (HMENU) 111, NULL, NULL);

现在，在 WM_COMMAND ，我尝试使用：

Now, in WM_COMMAND, I try to use:

SendMessage(btn, WM_SETCURSOR, 0, (LPARAM) cursor);

这是行不通的。

那么，如何改变鼠标的光标就点击这个按钮后？此外，如何更改鼠标光标，因为它悬停在按钮（如它悬停在网络浏览器链接时变为手）？

So how do I change the cursor of the mouse after it clicks the button? Also, how do I change the cursor of the mouse as it is hovering over the button (like it changes to a hand when hovering over links in web-browsers)?

推荐答案

使用此code改变单一控制的光标：

Use this code to change the cursor of a single control:

SetWindowLong(btn, GCL_HCURSOR, (LONG)cursor);

preferred方法，64位兼容性，方法是：

Preferred method, for 64 bit compatibility, is:

SetWindowLongPtr(btn, GCL_HCURSOR, (LONG_PTR)cursor);
