QT is a cross-platform C + + GUI application architecture, which provides a rich set of widgets, object-oriented, easy to extend, real component programming and so on, even more noticeable is that the most popular KDE desktop environment on Linux is built on the basis of the QT library. QT supports the following platforms: ms/windows-95, 98, NT and 2000;unix/x11-linux, Sun Solaris, HP-UX, Digital UNIX, IBM AIX, SGI irix;embedded-support Framebuffer's Linux platform. With the rapid development an

I am confused about the TCP protocol. The reason is that the local and remote code of UDP is exactly the same after UDP is finished. It is only initialized in the constructor, and the bound local IP address is different. This function is automatically completed by getip. Therefore, local and remote operations are the same. However, this is not the case for TCP. I will summarize it here (my level is very low, but it is not an entry level for cainiao. To sum up, I just want to prevent myself from

Both qwidget and its subclass can have a right-click menu, because qwidget has two functions related to the Right-click menu: Qt: contextmenupolicy () const Void setcontextmenupolicy (QT: contextmenupolicy Policy) Qt: contextmenupolicy enumeration types include QT: defaultcontextmenu, QT: nocontextmenu, QT: preventcontextmenu, QT: actionscontextmenu, and QT: customcontextmenu. The usage is as follows: 1) The default value is QT: defaultcontextmenu.It uses the context menu event contextmenuevent

, here we first give the complete program, and then go to the second part of the sentence analysis.1.

Copy the above mentioned 6 files to the project folder, as.3.

drive code is wrapped up in parentheses (); Hard drives are expressed in HD, followed by a set of numbers; Use "search Order" as the number of the hard drive, not the sort of hard drive line! (This is important!) ) The first hard drive to find is number No. 0, the second is number 1th, and so on; The first partition of each hard drive is codenamed 0, and so on. So, the first "hard drive to find" code is: "(hd0)", and the first partition of the hard disk

, there is no way to implement dirty reads, you must provide consistent reads, and the consistency read is implemented without blocking the user's DML.So how does the undo data achieve consistent reading? Or for the above example. When user A makes a query statement at 9, the server process records the SCN number at that point in time at 9, assuming that the SCN number is SCN9.00. Then 9 o'clock the full time of the SCN9.00 must be greater than or equal to the SCN number in the ITL

1. Code implementationThe project directory structure is as follows:The Addressbar class contains the Address bar and button two controls, connecting the Address bar carriage return and the button click Signal to the Gotosite () slot. When the Enter and click events occur, Gotosite () obtains the URL address and sends the GO (qurl) signal.Addressbar.h #ifndef addressbar_h #define ADDRESSBAR_H #include Addressbar.cpp #include "Addressbar.h" Address

The Bluetooth physical link ACL (asynchronous connectionless), and the other link is SCO (synchronous connection oriented), which is mainly used to transmit data communication with high time requirements. The Bluetooth baseband technology supports two connection types: Synchronous and targeted connections (SCO) and asynchronous connectionless connections (ACL. The former is mainly used for Synchronous voice transmission, and the latter is mainly used for grouped data transmission. The SCO connec

The qsignalmapper class is not a new concept. It already exists as early as qt2, and its functions are consistent. However, due to insufficient publicity efforts (few involved in this example), we may not know much about this kind of people. Therefore, I would like to write an article to introduce such functions and usage. The signalmapper class can be considered as a signal translation and repeater, it can translate a non-parametric signal into a signal with the int parameter, qstring parameter

The signal and slot mechanisms in QT are almost the same as the common C ++ member functions in QT, which can be virtual functions, overloaded functions, and common functions, protected or private. The slot can be connected with the signal. In this case, every time the signal is sent, the connect statement of the slot is automatically called: connect (sende, sign

go to the second part to perform a sentence-by-sentence analysis. 1. Open QT creator, create a qt4 GUI application, set the project name to mycom, and use the default options for others.

Lead HashMap is a common data structure, understanding the HashMap, to improve the efficiency of the code is a great help. HashMap optimizes the data structure in JDK1.8: It improves the efficiency of query and deletion . Of course, this also leads to a more complex structure, but through the careful reading of the source, still can grasp its essentials.
