如何在样式为SS_WHITERECT的静态控件中加载图标或位图？ [英] How to load icon or bitmap in a static control with style SS_WHITERECT ?

问题描述

大家好！



我想首先感谢所有花时间查看此主题并尝试提供帮助的人。



我在WM_CREATE中使用以下代码进行了静态控制：

 HWND hStatic1 = CreateWindowEx（NULL，  STATIC， ，WS_CHILD | WS_VISIBLE | SS_ICON | SS_WHITERECT， 250 ， 70 ， 50 ， 50 ，hwnd，NULL，GetModuleHandle（NULL），NULL） ; 

控件的背景正如MSDN参考中所描述的那样工作，所以我认为我需要做的就是添加在上述声明之后的代码：

 SendMessage（hStatic1，STM_SETIMAGE，（WPARAM）IMAGE_ICON，（LPARAM）hIcon）; 

但是，图标未加载。然而，如果我从窗口创建中删除SS_WHITERECT，图标会正确加载，但静态控件背景并不像我想要的那样。



所以我的问题是：



如何保留SS_WHITERECT提供的好处，同时能够加载图标以便显示？



虽然我没有经验，但我仍然有强烈的感觉，如果不使用区域和矩形，这是不可能的。



如果所以，我也会接受这些类型的解决方案。



我只是希望在其中心有一个带有图标的静态控件，其背景表现得好像它有风格SS_WHITERECT。



我使用WIN32 API在MS Visual Studio Express 2008，Windows XP，C ++中工作。如果需要任何其他信息（源代码或类似的东西），请求它，我将非常乐意提供它。

解决方案

静态控件的样式是分为两部分：低位到0x1F（ SS_TYPEMASK ）是定义控件类型的枚举，而高位定义样式。查看 WinUser.h 中的 SS _ * 定义。如果你结合 SS_ICON （0x03）和 SS_WHITERECT （0x06）你会得到0x07，这是 SS_BLACKFRAME 。



要实现想要的行为，请使用 SS_ICON | SS_CENTERIMAGE 并将控件的背景颜色设置为白色。另请注意，您必须使用 STM_SETICON 消息显示透明图标而不是 STM_SETIMAGE 。

我已经解决了！



首先，我必须向成员Jochen Arndt说谢谢，建议我让车主画出控件，在他的评论中提供详细的建议。



更新＃1：

如果窗口的背景不是位图，Jochen Arndt的解决方案是完美的。



我没有''当位图是窗口的背景时，找到了一种应用它的方法。



非常感谢任何对此的帮助，因为我相信他的解决方案更好（和我宁愿以这种方式解决我的问题！）。

我已经转换了我需要加载为静态c的图标ontrol'的背景在线位图，并用函数TransparentBlt（...）绘制。



对于有相同或类似问题的人，这里是代码摘录：

  //  存储位图的主窗口过程中的静态变量

  //   create owner drawn static control

Hello everyone!

I would like to start by saying thanks to everyone who takes some time to view this thread and try to help.

I have made a static control with following code in WM_CREATE:

HWND hStatic1 = CreateWindowEx( NULL, "STATIC", "", WS_CHILD | WS_VISIBLE | SS_ICON | SS_WHITERECT, 250,70, 50, 50, hwnd, NULL, GetModuleHandle(NULL), NULL);

The background of the control is working as described in MSDN reference, so I thought that all I needed to do is to add the following code after the above statement:

SendMessage( hStatic1, STM_SETIMAGE, (WPARAM)IMAGE_ICON, (LPARAM)hIcon);

However, the icon is not loaded. Yet, if i remove SS_WHITERECT from window creation, the icon loads properly, but static controls background doesn''t behave as I want it to.

So my question is:

How do I keep the benefits offered by SS_WHITERECT, and at the same time am able to load icon so it can be shown?

Although I am inexperienced, I still have a strong feeling that this will not be possible without working with regions and rectangles.

If so, I will accept those types of solutions as well.

I just want to have a static control with icon in its center and its background behaving as if it has style SS_WHITERECT.

I work in MS Visual Studio Express 2008, on Windows XP, in C++, using WIN32 API. If any other information is required ( source code or something similar ), please ask for it, I will more than gladly supply it.

解决方案

The styles for static controls are divided into two sections: The lower bits up to 0x1F (SS_TYPEMASK) are an enumeration defining the type of the control while the upper bits define styles. Have a look at the SS_* definitions in WinUser.h. If you combine SS_ICON (0x03) and SS_WHITERECT (0x06) you will get 0x07 which is SS_BLACKFRAME.

To achieve the wanted behaviour, use SS_ICON | SS_CENTERIMAGE and set the background color of the control to white. Note also that you must use the STM_SETICON message to display a transparent icon rather than STM_SETIMAGE.

I have solved it!

First, I must say BIG "thank you" to member Jochen Arndt for suggesting me to owner draw the control, and providing detailed suggestions in his comment.

UPDATE #1:
************************************************************

Jochen Arndt''s solution works perfect if the background of a window is not a bitmap.

I haven''t found a way to apply it when bitmap is window''s background.

Any help on this one is greatly appreciated,since I believe his solution is better ( and I would prefer to solve my problem this way!).

************************************************************

I have converted icon that I needed to load as static control''s background into bitmap online, and drew it with function TransparentBlt( ... ).

For people with same, or similar problems, here is the code snippet:

// needed for TransparentBlt( ... ), see MSDN documentation!

#pragma comment( lib, "Msimg32.lib")

// static variable in main window procedure that stores the bitmap

static HBITMAP hbSymbol = LoadBitmap( GetModuleHandle(NULL), 
		MAKEINTRESOURCE(IDB_BITMAP2) );

// create owner drawn static control

case WM_CREATE:
     {
        // The parametar (HMENU)2000 below sets ID for this control

	HWND hStatic1 = CreateWindowEx( NULL, "STATIC", "", WS_CHILD | WS_VISIBLE | SS_NOTIFY | SS_OWNERDRAW, 450,150, 25, 25, hwnd, (HMENU)2000, GetModuleHandle(NULL), NULL);
     }
     break;

// owner draw it

case WM_DRAWITEM:
     {
        switch( (UINT)wParam)
	{
	    case 2000:
	    {
		BITMAP bp;
                
                LPDRAWITEMSTRUCT lpDIS = (LPDRAWITEMSTRUCT)lParam;

		HDC hMemDC = CreateCompatibleDC( lpDIS->hDC);

		GetObject( hbSimbol, sizeof(bp), &bp);

		SelectObject(hMemDC, hbSimbol);

                // background used for my mask was RGB(255,0,255)

		TransparentBlt( lpDIS->hDC, lpDIS->rcItem.top,
                   lpDIS->rcItem.left, 
                   lpDIS->rcItem.right - lpDIS->rcItem.left, 
		   lpDIS->rcItem.bottom - lpDIS->rcItem.top, 
                   hMemDC, 0, 0, bp.bmWidth, bp.bmHeight, 
                   RGB( 255, 0, 255) );

		DeleteDC(hMemDC);
            }
            break;
            default:
                break;
	}
     }
     break;

// cleanup

case WM_CLOSE:

     DeleteObject(hbSimbol);

     DestroyWindow(hwnd);
		
     break;

case WM_DESTROY:

     DeleteObject(hbSimbol);

     PostQuitMessage(0);
		
     break;
