我正在创建带有子对话框作为页面的选项卡控件。
我通过Visual Styles
评论启用了#pragma
。我也打电话给InitCommonControlsEx
和#pragma comment( lib, "comctl32.lib" )
。
最初,当窗口加载,对话框及其常用控件具有适当的背景时,请参见下图:
在调整大小期间,事情并不那么一致 - >背景开始明显不匹配。我将在下面提供截图:
您可以清楚地看到checkbox
和static control
背景不正确,而在我看来dialog box
(创建用作儿童控件)具有适当的背景。
于2014年11月24日编辑:
将控件封入group boxes
之后,似乎没有绘画问题。我的显示器是旧的CRT(三星SyncMaster 753s),我的视力不好,但同样,似乎一切都画得很好。窗口在调整大小时仍然可怕地闪烁,但是I have tried everything in my power来修复它。
我该如何解决这个问题?
我还没找到任何东西,但在输入这个问题时我仍然是Goggling ......
以下是创建说明问题的演示的说明:
1。)在C++
;
Visual Studio
项目
2。)添加头文件,将其命名为pomocne_funkcije.h
并复制/粘贴以下内容:
#include <windows.h>
#include <windowsx.h>
#include <comutil.h>
#include <commctrl.h>
#include <stdio.h>
#include <vector>
#include <ole2.h>
#include <string>
#include <stdlib.h>
#include <locale.h>
#include <Uxtheme.h>
#pragma comment( linker, "/manifestdependency:\"type='win32' \
name='Microsoft.Windows.Common-Controls' version='6.0.0.0' \
processorArchitecture='*' publicKeyToken='6595b64144ccf1df' \
language='*'\"")
#pragma comment( lib, "comctl32.lib")
#pragma comment( lib,"Msimg32.lib")
#pragma comment( lib, "comsuppw.lib")
#pragma comment( lib, "UxTheme.lib")
3.。)在资源编辑器中创建对话框,添加复选框静态控件。
为对话框设置以下内容:
4.。)以下是main.cpp
的代码:
#include "pomocne_funkcije.h"

答案 0 :(得分:3)
您的选项卡对话框按Z顺序位于选项卡控件下方。这会在第一次调整大小时引起疯狂的透支问题。将选项卡对话框作为子级添加到主窗口后,调用SetWindowPos(tab, HWND_TOP, 0, 0, 0, 0, SWP_NOACTIVATE | SWP_NOMOVE | SWP_NOSIZE)
将其移至Z顺序的顶部。
有这个确切的问题;花了我几天时间才弄清楚。我在Visual Studio中创建了一个简单的应用程序:
InitCommonControlsEx()
WM_PRINTCLIENT
或类似事物的花哨处理EnableThemeDialogTexture()
中的WM_INITDIALOG
我去XP上进行了检查,……除了闪烁之外,它工作得很好而且看起来很漂亮。
我添加了WS_CLIPCHILDREN
,突然之间就可以完美地复制您的屏幕截图。我首先想到的是原因。
我不断推动并添加了WS_COMPOSITED
以防止闪烁,然后标签页窗口突然消失了-完全被标签的背景所覆盖。现在我意识到Z顺序有错。
子窗口始终创建在Z顺序的底部,即在标签控件下方。您的代码永远不会使它们向上移动。仅靠运气/透支显示这些选项卡,从而产生您观察到的伪影。固定Z顺序,将不再有伪像。
