In the previous article, I showed how to connect the x server and how to create a window. Creating a window is fundamental to writing GUI programs. There are two other key points in GUI programming, one is event handling and the other is drawing in Windows. In this article, you will show how to use XCB to draw in a window.Let's look at a sample code and how it works, with the following code:1#include 2#include 3 4#include 5 6 int7 Main ()8 {9

In the development process, we often come from defining the view. It is a basic component of user interaction, responsible for displaying images and handling events, and is often inherited as a base class for custom components. So today, let's go through the source code to carefully analyze how the view was created and what happened during the drawing process.CreateFirst, there are four overloaded forms of the View public constructor: The vi

This article Code Is developed based on beta2 More and more web applications require charts for data display and analysis. For example, the voting result is displayed, and the company's production Statistical Chart is displayed and analyzed. Charts are used to display data, which is intuitive and clear. Traditional ASP technology does not support drawing charts, so you have to use Active X or Java applets to implement this function. ASP. NET solves

: All drawing designs need to be done on a background image, and the canvas is actually a temporary area in memory for storing information about the image. Future image operations will be based on this background canvas, which is managed similar to the canvas we use when drawing.

Process Photoshop is a very simple and practical design software. Many features, in addition to doing graphic design, used to modify their own photos are also very good. Here's a picture of CG anime illustrated with Photoshop. Photoshop does not have some very professional drawing tools in the software. I used Photoshop to paint almost exclusively with [pen]. 1 Open a line (as shown in Figure 9-01), the use of the toolbar "spray pen", the number doe

Matlab plot drawing coordinate settings for font, font size, range, interval, etc. The number, range, and interval adjustment of MATLAB coordinates Matlab drawing when only the plot function out of the diagram does not necessarily conform to their most desired format, often to coordinate the number, range, interval to do processing. Although it is not very difficult to operate, but it is often used, but al

Introduction to 4.6.1 Sketch command The "Freehand drawing" feature, the "sketch" command, is provided to make it easier for users to use the AUTOCAD,AUTOCAD system. With this function, the user can use the fixed-point device as a brush to draw some irregular boundaries, such as contour lines, signatures, etc. Freehand painting is essentially a series of consecutive lines or multiple lines. 4.6.2 Sketch Command detailed The format for invoking the

Introduction Matplotlib is a very useful Python drawing library. It combines well with numpy, but is itself a separate open source project.

When I wrote some technical articles, I often had a message from readers asking me what tools I used to draw. In fact, I feel that they may have asked the wrong question, because I have tried to draw a good picture of a variety of different drawing tools software, but finally found that it is not possible to draw a good diagram and tool relationship is not big.Why?The programmer is not writing code, why do you need to draw? Many programmers think it's

To give you illustrator software users to detailed analysis to share the design of complex smooth curve of the drawing tutorial. Tutorial Sharing: Adobe Illustrator, like other planar vector software, uses Bezier curves and three curves to describe and control curves with four control points, while in Illustrator the controls are anchored to anchor points and handles. So a curve is from the end of two anchor points to contro

Drawing mode is how to determine the color of overlapping parts when a later drawing overlaps with a previously drawn shape. For example, the later drawn overlay was previously drawn, or the two colors that were drawn earlier are mixed with some rule. There are two main types: normal mode and different or pattern, which is that the pattern that is drawn after is covered by the previously drawn shape, so tha

Statement: Here I will not use too much text to explain what canvas is, I believe that the people who know the canvas know its charm, if you are more unfamiliar with the canvas, suggest you can consult the relevant information to understand. Here I will take a detailed note of the canvas drawing in detail, so that everyone and yourself can learn later. Then the next step is to go directly into the note content of the study:To create a canvas element f

How does delphi use basic drawing functions to draw statistical charts? A drawing tool that comes with Windows cannot meet our drawing needs in any way. Many effects need to be implemented in other tools. How are these advanced functions implemented? How can we manipulate some basic attributes and functions so that they can ultimately achieve what we want? Here
