Some of the most popular upload vulnerabilities in the past, such as mobile networks, mobile devices, and so on! The popularity is crazy. Get webshell through upload! What is weshell .! Webshell is also called ASP {remote control software }..! Very

In the current information security field, it seems that risk management has become synonymous with information security. Security seems to be inseparable from risk management. Before building a comprehensive security system, risk assessment is

Q: What is network security? A: network security means that the hardware, software, and data in the network system are protected and shall not be damaged, changed, or disclosed by accident or malicious reasons, the system can operate

The first lesson of any programming technique is basically hello, world!, and I don't want to break the routine intentionally-it should be a review of QT's history first, but it doesn't matter if you don't say that. Maybe some people always want to

This article supporting source code This time, we'll explain how to use graphics view to implement the artboard as described earlier. There are a lot of good words about graphics view, but there is no concrete example of where it is. Now we will

Through the previous chapters, we have been able to draw something, mainly using the qpainter correlation function. Today, we are looking at the Qpainter coordinate system. As with many coordinate systems, the origin of the default coordinates of

First of all, we must first bring up the last code. void　PaintedWidget::paintEvent(QPaintEvent　*event) { QPainter　painter(this); painter.drawLine(80,　100,　650,　500); painter.setPen(Qt::red); painter.drawRect(10,　10,　100,　400);

When QT creates a Qevent event object, it invokes the Qobject event () function to distribute the events. Sometimes you may need to do something else before calling the event () function, for example, some components on the dialog may not need to

This is the last part of the Qt Standard dialog box. As the name shows, Qinputdialog is used to receive input from the user. Qinputdialog provides a few simple static functions that are used to quickly create a dialog box, just as Qcolordialog

The following is our progress, starting with the Qt Standard dialog box. The so-called Standard dialog box, in fact, is a number of QT built-in dialog boxes, such as file selection, color selection and so on. Today I'd first introduce Qfiledialog.

On the basis of the previous Qmainwindow, we began to build our application. Although there is already a framework, but, exactly, we still have a line of code did not write it! The work below is not so easy! In this section, we add menus and

Next, here is the source code section: #include #include "finddialog.h" Finddialog::finddialog (qwidget *parent) : Qdialog (parent) { label = new Qlabel (tr ("Find what:"); lineedit = new Qlineedit; Label->setbuddy (Lineedit);

As the name suggests, absolute positioning is the use of the most original positioning method, given the coordinates of this component and the length of the value. In this way, Qt knows where to put the components and how to set the size of the

thinkphp path mode and program run route In thinkphp, there are four main types of views, namely 1, Normal mode, 2: Path mode, 3: Override mode, 4: Compatibility mode. In the beginning of the development of the learning process, it is recommended

Now it's time to continue talking about Qt's standard dialog box! This time, let's talk about Qmessagebox and a couple of similar dialogs. In fact, we have used the Qmessagebox, in the previous several procedures. However, at that time was roughly

Today's content is mainly to continue to improve the previous program. We're going to add a status bar to our program. The status bar is located at the bottom of the main window and provides a place to display information such as tooltips.

Although QT provides a handy quick development tool Qtdesigner used to drag and drop interface elements, I'm not going to introduce this tool now, because our study relies largely on hand-written code, and premature contact design tools do not allow

More people to my support Ah! Some friends also suggested that the previous sections on the event tutorial lacked examples. Because the event is more difficult to do an example, also did not go to write, just to write about it. Today brings in a new

The content of this chapter is also about QT events. Perhaps this chapter can not have a complete example, because for the event is always feel very abstract, or from the bottom of the better to understand it! Before we talk about the role of
