如何在文字按钮上放置图标? [英] How to put an icon on a text button?

问题描述

我想在同一按钮上同时显示图像图标和文本，例如在Word中.

我在按钮上设置了一个图标，但文本消失了.

  HANDLE hBmp =(HBITMAP)LoadImage(g_hDllInstance，MAKEINTRESOURCE(IDB_BITMAP4)，IMAGE_BITMAP，空值，空值，LR_DEFAULTCOLOR);HWND hwndButton = CreateWindowEx(空值，_T(按钮")，_T("SOME TEXT")，BS_BITMAP |WS_VISIBLE |WS_CHILD，point.x-47，点-3，36岁40岁hWnd，(HMENU)200，空值，空值);发信息((HWND)hwndButton，(UINT)BM_SETIMAGE，(WPARAM)IMAGE_BITMAP，(LPARAM)hBmp); 

我还尝试将图标设置在按钮上较小的子窗口中，但是由于某种原因，我的子窗口不可见.

I want to have both an image icon and text on the same button, like here in Word for example.

I set an icon on a button, but the text disappears.

HANDLE hBmp = (HBITMAP)LoadImage(g_hDllInstance,
    MAKEINTRESOURCE(IDB_BITMAP4),
    IMAGE_BITMAP,
    NULL,
    NULL,
    LR_DEFAULTCOLOR);
HWND hwndButton = CreateWindowEx(
    NULL,
    _T("BUTTON"),
    _T("SOME TEXT"),
    BS_BITMAP | WS_VISIBLE | WS_CHILD,
    point.x - 47,
    point.y - 3,
    36,
    40,
    hWnd,
    (HMENU)200,
    NULL,
    NULL);
SendMessage(
    (HWND)hwndButton,
    (UINT)BM_SETIMAGE,
    (WPARAM)IMAGE_BITMAP,
    (LPARAM)hBmp);

I have also tried to set the icon on a smaller subwindow on my button, but for some reason my subwindow is not visible.

解决方案

Instructions on how to get a button to display both an image and text are outlined in the Button Styles reference¹:

The appearance of text or an icon or both on a button control depends on the BS_ICON and BS_BITMAP styles, and whether the BM_SETIMAGE message is sent. The possible results are as follows.

BS_ICON or BS_BITMAP set? | BM_SETIMAGE called? | Result  
--------------------------+---------------------+--------------------  
Yes                       | Yes                 | Show icon only.  
No                        | Yes                 | Show icon and text.  
Yes                       | No                  | Show text only.  
No                        | No                  | Show text only

In other words: Don't set the BS_ICON or BS_BITMAP style (but do set the BS_TEXT style), and send a BM_SETIMAGE message once the button has been created.

To see this in action, create a standard Windows Desktop application in Visual Studio, and apply the following changes:

• Enable visual styles. This is easiest done by placing a #pragma linker directive into the only compilation unit:

  #pragma comment(linker,"\"/manifestdependency:type='win32' \
  name='Microsoft.Windows.Common-Controls' version='6.0.0.0' \
  processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*'\"")
  

• Create the button in the main window's WM_CREATE handler:

  case WM_CREATE:
      {
          HWND btn{ ::CreateWindowExW(0x0, L"BUTTON", L"Button text",
                                      WS_VISIBLE | WS_CHILD | BS_TEXT,
                                      10, 10, 200, 50, hWnd, (HMENU)110,
                                      nullptr, nullptr) };
          HICON icon{ (HICON)::LoadImageW(::GetModuleHandle(nullptr),
                                          MAKEINTRESOURCEW(107),
                                          IMAGE_ICON, 32, 32, 0x0) };
          ::SendMessageW(btn, BM_SETIMAGE, IMAGE_ICON, (LPARAM)icon);
      }
      break;
  

  Make sure to adjust the numeric constants as needed. 110 is the button's control identifier, 107 is the resource ID of the wizard-generated application icon resource, and 32 are the width and height of the requested icon.

This code produces the following output:
