In fact, the solution to the problem is very simple: QT does not support the path of Chinese, the source of the path of all the changes to English can solve the problem.The first problem occurs when I run the online example program, rebuild the compilation is also an error, hint:Cannot find FILE:F:\PRO\QT\QT5 development and instance \ Book source program \ch1\ch101\dialog\dialog.pro.21:55:03: Process "D:\

Qt sends messages to Win32 very easily, but it is very complicated to obtain Windows messages. Finally, I thought of a method that is not perfect, but it is also the only way that I can achieve it now, the basic principle is to use VC to compile an mfc dll, which creates a transparent form and uses this DLL to obtain Win32 API messages. The source code has been tested in vs2010 vs6.0 QT 4.7 Below is an i

I. Preface I spent some time studying ogre at home during the summer vacation, basically a wiki tutorial every day. After finishing the preliminary tutorial, I felt that I could not proceed, because there were a lot of things that I had to understand, so I wanted to get in touch with something more "low-end. Open-source, of course, OpenGL is required. If we use QT for cross-platform applications, we will spend some time studying it. But at that time,

In accordance with the standard QT Tutorial (http://www.qter.org/forum.php?mod=viewthreadtid=781) practice, it is found that removing the main interface and opening the windows in multiple languages is no problem.

Write static dynamic graph with QT, static dynamic histogram with qtRecently, several projects have been successively implemented, requiring the use of curves and bar charts to dynamically display data. Therefore, we have specially studied the qcustomplot open-source Drawing Library! As kimit in the garden said, although qcustomplot is a header file and implementation file, it is easy to use, but the code is much more messy than QWT, and the readabili
