看不见的CButton，直到按下? [英] Invisible CButton until pressed?

问题描述

嗨
有关如何执行此操作的任何想法?

我的想法是创建一个CDialog，加载一个bmp图像来填充整个对话框.此bmp图像将是我的程序的外观.图片将包含按钮.在这里，我将创建一个CButton owner-draw-class，其中在按下按钮时会在该区域显示一个新图片.当不再按下按钮时，CButton应该是透明的/不可见的.

这是我的问题的最后一部分.我不知道如何从cbutton恢复/重画对话框的bmp图像.有什么想法吗?

此致
Ole

Hi
Any ideas on how to do that?

My idea was to create an CDialog, load an bmp-image that fills the whole dialog. This bmp-image would be how my program should look like. The picture would contain buttons. Here i will make an CButton owner-draw-class where i show a new picture (on that area) when the button is pressed. When the button is no longer pressed, the CButton should be transperant/invisible.

It is the last part that is my problem. I dont know how to restore/redraw the dialog''s bmp-image from the cbutton. Any ideas?

Kind regards
Ole

推荐答案

没关系，我只是复制了原始背景并在按钮不可见时显示该背景.喜欢:

透明列表框 [

Never mind, I just copied the original background and display that when the button should be invisible. Like:

Transparent ListBox[^]

I would just be smarter if I could get the parent-window (the dialog) to redraw the area where the button is placed... without the button getting a redraw-command.

Kind regards
