使整个优化校准透明 [英] Make entire Picture Control Transparent

问题描述

大家好，



我尝试以下情况很长一段时间但无法成功。

输入：对话框2图片控件，mfcbutton，滑块控件和几个按钮。



1.我需要添加一个jpg图像作为我对话框的完整背景。

解决方案：我通过使用CImagePreviewStatic实现了这一目标。

这对我来说很好。



2.第二个图片控件位于第一个顶部 - 我有一个Bitmap附加或者我使用OnPaint（）绘制温度测量等图形，使用SolidBrush绘制折线等。



基于Slider控件输入，我现在想要第2个图片控件透明，它会以某种最大值消失。

另外，我提到的mfcbutton是一个位图添加ed，甚至它的透明度应该相对于滑块控制值而改变。



我只使用Visual Studio 2010和MFC C ++。



如果您知道任何解决方案，请告诉我。

提前谢谢。

Hi All,

I am trying the below scenario since a long time but unable to succeed.
Inputs: Dialog box with 2 Picture controls, mfcbutton, slider control and few buttons.

1. I need to add a jpg image as complete background of my dialog box.
Solution: I have achieved this by using CImagePreviewStatic.
Below is the link:
https://www.google.co.in/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&ved=0CCMQFjABahUKEwiehpHWmYXGAhULq7wKHeNQABo&url=http%3A%2F%2Fwww.codeproject.com%2FArticles%2F6354%2FA-simple-image-preview-class-using-GDI&ei=XDd4VZ7oMovW8gXjoYHQAQ&usg=AFQjCNEcO0kiW8Ie-voNfaGMIDB2P3D0Ig&bvm=bv.95039771,d.dGc&cad=rja[^]
This is working fine for me.

2. 2nd picture control is positioned centered on top of 1st- I have an Bitmap attached or I draw a graph like temperature measurement etc using OnPaint() with SolidBrush to draw polylines etc.

Based on the Slider control input, I now want to make this 2nd picture control transparent in a way that it fades to some maximum value.
Also, the mfcbutton that I mentioned is having a bitmap added, even its transparency should change with respect to slider control value.

I am using Visual Studio 2010 and MFC C++ only.

Please let me know if you are aware of any solutions.
Thank you in advance.

推荐答案

最后，我很高兴发布这个答案。

分层Windows对我来说真是太棒了。



这已经解决了。



我用过：

Finally, its my pleasure to post this answer.
Layered Windows as worked just so amazing for me.

This is resolved.

I have used:

// Make this window 70% alpha
SetLayeredWindowAttributes(hwnd, 0, (255 * 70) / 100, LWA_ALPHA);

如果我希望对话框中的剩余区域变得透明，我将只添加RGB颜色并在最后一个参数中添加LWA_ALPHA | LWA_COLORKEY



我在Slider Control的VScroll事件中添加了这个。这样，alpha百分比可以通过滑块控件的位置来控制。

If I want the remaining area on the dialog to be made transparent, I will just add the RGB color and in last parameter LWA_ALPHA | LWA_COLORKEY

I have added this on VScroll event of the Slider Control. So that the alpha percentage can be controlled by the position of the slider control.
