Xiaobian to share with you wxWidgets wx/wx.h how to solve the header file contains problems, I believe most people do not know how to share this article for your reference, I hope you read this article after a great harvest, let us go to understand it!

description

wx.h includes all the necessary wxWindows headers, so you only need to include them once to use all the objects encapsulated in wxWindows completely, regardless of the header file to which the current object belongs. Of course, you can also have the option of including a header file for each control

For example, in order to use

wxTimerEvent, must contain wx/event.h

wxTimer, must contain wx/timer.h

wxPanel, must contain wx/panel.h

recommend

In the header file, call #include "wx/wx.h"

remind

When the compiler supports preprocessors, the wxprec header file can be used. When it is not supported, wx/wx.h should be included

Standard coding

#include "wx/wxprec.h"

#ifndef WX_PRECOMP

#include "wx/wx.h"

#endif

problem

The wx/wx.h header file is already included, and the following error occurs when using the wxBufferedPaintDC object:

Incomplete types are not allowed

solve

#include "wx/dcbuffer.h"

reason

Some versions of the wx.h file do not yet contain the wx/dcbuffer.h header file, which can be added directly to the wx.h file

The above is "wx/wx.h in wxWidgets how to solve the header file contains the problem" all the content of this article, thank you for reading!
