Qt Address Book (2) Add addresses, qt Address Book add addresses In the last Qt Address Book (I) interface design, we mainly implemented the address book interface and used the layout manager to layout elements, it also explains the concepts of "subclass" and "ownership. In this article, we will add three QPushButton buttons on the interface to save the Name and

Qt custom tag button and qt custom tag When you get started with Qt, you will be surprised by its extremely convenient cross-platform approach and want to try Qt. Gradually, you will find that some of Qt's built-in controls cannot meet your own needs. At this time, we need to define our own controls. In general, there

The year may almost passed, and the students started school. I think the campus will be a lot more lively, and the CSDN will also be a bit lively. The Mid-Autumn Festival has passed, and there are still many unfinished moon cakes around you. Therefore, you can eat them as breakfast every morning, hoping they will not be wasted. This month has many things and is very busy, so it is so late that I can take the time to write an article. This time I introduced Qt's support for OpenGL. I attended the

Assuming that you performed the Qt on Android app on the target Android device, you might want to see the log information for the program output. There are ADB tools in the Android SDK, and when you are connected to a target device, you can use ADB logcat to view the log of the app output on your Android device.Let's introduce the use of ADB too

QT Development (46)--the basis ofQT database programmingFirst,Introduction to the Qt SQL module 1.

QT under the static compile Qt, according to my experience, if according to the kind of windows under the Official SDK installed directly after the file to compile is not feasible, need to download QT source package directly, At present, the source of Nokia is called QT-EVERYWHERE-OPENSOURCE-SRC tar package, to the onl

The provision of QT products is a dual licensed software licensing model. In this dual licensing mode, QT products can be developed not only for proprietary software under commercial license, but also for free and open source software under the GPL (general Public License, version 2 or version 3). In other words, the QT software itself is open source and free to

Play with Qt (1) and play with Qt ( Recently I have been reading some things about the game engine. I have several small game ideas. In fact, the implementation is quite troublesome. I want to find a game engine to see if it can be coded. A lot of 2D engines were found after the revolution, among which the domestic cocos2dx seems to be widely used, but many people disagree with this. As a result, I decided

Obj-c in the eyes of qt/c++ developersFor the first time we defined iOS apps, I had to learn objective-c related grammar and knowledge for developers from Qt/c++.To make it easier for readers to understand the content of this blog, I'll describe a lot of what I've learned. This will be many other brain dumps rather than a single tutorialSo I still hope it will be very helpful for you, I will first write the

BrieflyIn debugging the program, sometimes need to debug into Qt source code, which not only helps us understand the internal implementation mechanism, but also to solve some hidden problems are very helpful.All know F11 is "single Step into", but in the process of debugging, press F11 but can not enter. Some people say that the need to statically compile Qt can, in fact, just need a few simple configuratio

array of wchar_t to hold Unicode charactersSecond, the character, string in QTQt as a cross-platform framework, the design of the first consideration of the character of the problem;It encapsulates a qstring representing a string, which is a UTF-16 encoded class, and encapsulates a Qchar class that represents a wide character;Then there's the problem: the code in VS is GBKSo just assign the string to qstring as follows:QString str = "A section of Chinese"; Ui.lineedit->settext (str);Running out

How does the Qt application process Chinese parameters during drag-and-drop, and qt drag-and-drop Chinese parameters? You have developed an application using Qt. When you drag and drop a file to your exe and start your application, the main () function may receive Chinese parameters. How can this problem be solved correctly? The Code is as follows: QTextCodec

Qt recursive non-recursive traversal file, qt recursive non- The biggest advantage of qt is that it is cross-platform. Although it is said that qt is well-designed and has a wide range of documents, qt has never been so cool. However, cross-platform architecture can save a l

QT multithreading notes and qt Multithreading 1. it is not convenient to use QThread when QT multithreading involves a large amount of data interaction between the main thread and sub-thread, because the run () function itself cannot accept any parameters, therefore, data can only be obtained through the interaction between the signal and the slot. If only the si

Design of the waiting dialog box in Qt and the waiting dialog box in Qt A waiting dialog box is used to prompt the user to operate the Qt program for a long time.Qt has a standard QProcessDialog to partially implement this function, but the disadvantage is to calculate the progress. Second, you can cancel it halfway. Therefore, we generally use a custom dialog b

The words are connected to the article. After successfully configuring Qt+lua+tolua, we can implement classes that use each QT in a Lua script. Look directly at the code.#include "include/lua.hpp" #include The author writes several functions of qwidget into the form of static and binds them with Tolua. This makes it possible to use a bound function smoothly in a LUA script. The contents of the following LUA

Qt Property system QT provides a clever property system similar to the property systems supported by some compilers. However, as a platform-and compiler-agnostic library, QT cannot rely on non-standard compiler features such as __property or [property]. QT's solution can be supported by standard C + + compilers under any QT
