Recently, many kinds of GIF expressions on QQ. Every one of them is a classic. So I wanted to convert it into a static picture ... Never learned PS. So I wrote a few lines of code. Completed. The core code is as followsMainly with the help of the Qmovie class. File read Mode Select Qmovie::cacheall This allows you to cache all pictures. Then end the jumptoframe to toggle the picture. The loop is done.[CPP]View Plaincopy

Tags: OS SP problem BS work as nbsp project recordA strange problem in recent projects is that when the final m_lastpos is recorded as the middle position of the current widget, qcursor is set as the current middle position.At this time, when I started to move, I found that the offset has a very strange maximum value. Later I found that because my working environment is a remote machine environment, when I call the global qcursor of the system :: when setpos is used, the cursor is still in my or

When we write the QT development interface program, we often use the code of each module or the QML file to separate, so as not to qml too many files and look a bit messy
Below, let's take a look at:
We write each module separately in a. pri file
, and then we include them in the. Pro file
Include ($ $PWD/.. /.. /.. /BASE/BASE.PRI)
Include ($ $PWD/.. /.. /CAPB.PRI)
Two. pri files are two different modules

This article discusses the basic installation from Ubuntu, that is, the installation package required to develop the Qt application after the default installation from the CD installation disk. In this article, the Environment ubuntu9.04-topics, wubi.exe installation below is the need to do a few steps 1) after installing the sudoapt-getinstalllibqt4-dev package, you can write
program I write can run on Linux ARM,
Therefore, we need an IDE for development. The program compiled by IDE can run on ARM;
What Should IDE choose? Some articles use QTDesinger and some use QTCreator.
After data query, both QTDesinger and QTCreator can be used. QTCreator is more similar to the commonly used VC ++ IDE;
OK6410 Linux has two more image interfaces: QTOpia2 and QT4.
I usually write VC programs, so I prefer QTCreator (in fact, QTDesinger
