GTK2.0 学习 1. 准备 首先观察 gtk2.0 开发包为我们提供的一个文档。阅读下文,您可以知道,对于刚开始开发,我们应该做些什么。 Then add the bin folder to your PATH. Make sure you have no other versions of GTK in PATH. Run: pkg-config --cflags gt

GTK2.0+学习

1.准备

首先观察gtk2.0开发包为我们提供的一个文档。阅读下文,您可以知道,对于刚开始开发,我们应该做些什么。

Then add the bin folder to your PATH. Make sure you have no other

versions of GTK+ in PATH. Run:

    pkg-config --cflags gtk+-2.0

and verify that it prints out something reasonable. Run:

    gtk-demo

and verify that it works.

 

To use the MS-Windows theme engine, create a file etc/gtk-2.0/gtkrc

containing the line:

gtk-theme-name = "MS-Windows"

2. Visual Studio 2008中搭建GTK+开发环境

1.http://www.gtk.org/download-windows.html上下载All-in-one bundles包,目前有2.162.22。下载完后解压到一个任意的目录中,如“D:\Environment\gtk”。

2.系统环境变量配置:我的电脑 ->属性->高级属性->环境变量->系统变量->Path,在Path值的最后添加“;D:\Environment\gtk\bin”。

3.设置VS2008编译环境

1)设置包含文件目录:工具->选项->项目和解决方案->VC++目录->显示一下内容的目录->包含文件,添加GTK目录include文件夹和include文件夹里的所有一级文件夹,共12项。还有lib文件夹的子文件夹里面的两个include文件夹,如下图所示。

2)转到库文件视图,添加GTK目录的Lib文件夹。

4.新建C++的空项目,在项目->项目属性->配置属性->链接器->附加依赖项中添加:

glib-2.0.lib gtk-win32-2.0.lib gdk-win32-2.0.lib gobject-2.0.lib gdk_pixbuf-2.0.lib gthread-2.0.lib gmodule-2.0.lib pango-1.0.lib intl.lib

5.测试:新建CPP文件,写入如下代码,可以正常运行则配置成功。

#include  

int main(int argc, char** argv) 

        GtkWidget* window; 

        gtk_init(&argc, &argv); 

        window = gtk_window_new(GTK_WINDOW_TOPLEVEL); 

        g_signal_connect(GTK_OBJECT(window), "destroy", G_CALLBACK(gtk_main_quit), NULL); 

        gtk_widget_show(window); 

        gtk_main(); 

        return 0; 

}

3.开发中字体问题

在程序运行的时候遇到如下警告时:

 

(GTKTest01.exe:4876): Pango-WARNING **: couldn't load font "微软雅黑 Not-Rotated

 9", falling back to "Sans Not-Rotated 9", expect ugly output.

 

(GTKTest01.exe:4876): Pango-WARNING **: couldn't load font "微软雅黑 9", falling

 back to "Sans 9", expect ugly output.

 

这所代表的意思是系统加载系统默认的字体格式时,我们的gtk程序无法识别。

如在第一部分所说gtk程序开发时加载MS-Windows theme engine。所以我们要人为改变它的gtk程序运行时所用的字体格式。

C:\gtk\share\themes\MS-Windows\gtk-2.0找到gtkrc文件,在文件末尾加上如下内容:

style "user-font"

{

         font_name="Simsun 10"

}

widget_class "*"style"user-font"

这样我们就为gtk程序指定了字体。

4.实例学习

GTK2.0+学习

图1.第一个例子

对于以上类子,我们首先要介绍下gtk窗口的构成结构:

Windowà GtkAccelGroupàvbox,hbox…..(布局)àscrolledgroupà各种控件。

注意box的添加控件方法是gtk_box_pack_start.

而对于普通的容器添加使用gtk_container_add.

需要特别介绍的是menu的使用:

MenubaràmenuItemàmenuàmenuItem

GTK2.0+学习

图2.menu

 

而从menuItem加到menumenubar中,采用gtk_menu_shell_appen方法,而menumenuItem中采用gtk_menu_item_set_submenu方法。

 

然后就是对于事件的使用,采用g_signal_connect.而对于函数的参数传递,有待继续学习。

5.存在问题

1.事件处理参数传递

2.头文件xxx.h的处理作用

3.GtkTextView可写,在上加右击事件,增加弹出菜单之后的可写性。

Explain the ACID properties (Atomicity, Consistency, Isolation, Durability).Explain the ACID properties (Atomicity, Consistency, Isolation, Durability).Apr 16, 2025 am 12:20 AM

ACID attributes include atomicity, consistency, isolation and durability, and are the cornerstone of database design. 1. Atomicity ensures that the transaction is either completely successful or completely failed. 2. Consistency ensures that the database remains consistent before and after a transaction. 3. Isolation ensures that transactions do not interfere with each other. 4. Persistence ensures that data is permanently saved after transaction submission.

MySQL: Database Management System vs. Programming LanguageMySQL: Database Management System vs. Programming LanguageApr 16, 2025 am 12:19 AM

MySQL is not only a database management system (DBMS) but also closely related to programming languages. 1) As a DBMS, MySQL is used to store, organize and retrieve data, and optimizing indexes can improve query performance. 2) Combining SQL with programming languages, embedded in Python, using ORM tools such as SQLAlchemy can simplify operations. 3) Performance optimization includes indexing, querying, caching, library and table division and transaction management.

MySQL: Managing Data with SQL CommandsMySQL: Managing Data with SQL CommandsApr 16, 2025 am 12:19 AM

MySQL uses SQL commands to manage data. 1. Basic commands include SELECT, INSERT, UPDATE and DELETE. 2. Advanced usage involves JOIN, subquery and aggregate functions. 3. Common errors include syntax, logic and performance issues. 4. Optimization tips include using indexes, avoiding SELECT* and using LIMIT.

MySQL's Purpose: Storing and Managing Data EffectivelyMySQL's Purpose: Storing and Managing Data EffectivelyApr 16, 2025 am 12:16 AM

MySQL is an efficient relational database management system suitable for storing and managing data. Its advantages include high-performance queries, flexible transaction processing and rich data types. In practical applications, MySQL is often used in e-commerce platforms, social networks and content management systems, but attention should be paid to performance optimization, data security and scalability.

SQL and MySQL: Understanding the RelationshipSQL and MySQL: Understanding the RelationshipApr 16, 2025 am 12:14 AM

The relationship between SQL and MySQL is the relationship between standard languages ​​and specific implementations. 1.SQL is a standard language used to manage and operate relational databases, allowing data addition, deletion, modification and query. 2.MySQL is a specific database management system that uses SQL as its operating language and provides efficient data storage and management.

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

What are the key metrics to look for in an EXPLAIN output (type, key, rows, Extra)?What are the key metrics to look for in an EXPLAIN output (type, key, rows, Extra)?Apr 15, 2025 am 12:15 AM

Key metrics for EXPLAIN commands include type, key, rows, and Extra. 1) The type reflects the access type of the query. The higher the value, the higher the efficiency, such as const is better than ALL. 2) The key displays the index used, and NULL indicates no index. 3) rows estimates the number of scanned rows, affecting query performance. 4) Extra provides additional information, such as Usingfilesort prompts that it needs to be optimized.

What is the Using temporary status in EXPLAIN and how to avoid it?What is the Using temporary status in EXPLAIN and how to avoid it?Apr 15, 2025 am 12:14 AM

Usingtemporary indicates that the need to create temporary tables in MySQL queries, which are commonly found in ORDERBY using DISTINCT, GROUPBY, or non-indexed columns. You can avoid the occurrence of indexes and rewrite queries and improve query performance. Specifically, when Usingtemporary appears in EXPLAIN output, it means that MySQL needs to create temporary tables to handle queries. This usually occurs when: 1) deduplication or grouping when using DISTINCT or GROUPBY; 2) sort when ORDERBY contains non-index columns; 3) use complex subquery or join operations. Optimization methods include: 1) ORDERBY and GROUPB
