Drawing lines with GTK+ and Cairo without removing what is already drawn

由 ╄→гoц情女王★ 提交于 2020-05-31 06:54:40
问题 Currently I am writing a program in C, on a linux system (Raspberry Pi to be exact) which should draw to a GTK window using Cairo. I've been following the tutorial at: http://zetcode.com/gfx/cairo/ . But it is way to vague with it's explanations at certain points. It does not explain two points that I really need: I can't figure out a way to draw to the window with a proper function call. It removes what is already drawn. I need a piece of code that does some simple things, in a very Object

由 对着背影说爱祢 提交于 2020-05-17 06:09:09
问题 I'm using PyGObject/GTK+ with Python3.7 on Windows and is worried about how to package my app. With official Python ecosystem, it's easy to use freezers and venvs. However, the PyGObject and GTK+ on Windows requires the MingW environment to run. Does this mean that I have to package the entire MingW, along with GTK+? How should I freeze the app? 回答1: Since no one cares soon enough, I'll report my findings here. The short answer, as of the date I write this post, is: The PyGObject eco-system

使用IDEA搭建Java源码分析环境

系统环境 版本： JDK1.8.0_211 创建Java项目 使用IDEA新建Java项目； 将源码文件 src.zip 解压到新建项目的 src 目录下； 移除项目与 Java 安装目录下源码压缩文件的关联，在 Project Structure 的 SDKs 中创建一个新的 JDK ，仍然使用 Java 安装目录的 Classpath ，但要将 Sourecepath 中的 src.zip 修改为项目中的 source 目录。 在 Project Structure 的 Modules 的 Dependencies 中，将 Module SDK 改为新创建的 JDK ； 创建 Main 类，包含 main 方法即可。 运行Main类中main方法 运行发现以下问题： 系统资源不足，抛出 OutOfMemoryError ； 程序包 UNIXToolkit 和 FontConfigManager 不存在； 找不到 com.sun.tools.xx 等类。 解决方案 针对资源不足问题，在 Settings -> Build, Excution, Deployment -> Compiler 中修改 Build process heap size 为 1200 即可。 程序包不存在，需要在 OpenJDK 找到与当前版本对应的这两个 .java 文件，在项目的源代码目录下创建 sun

GTK Retrieve values from multiple widgets on button press

由 巧了我就是萌 提交于 2020-03-25 16:50:20
问题 I'm trying to retrieve a value from both an Entry field and a ComboBox in my window on a button press. I'm currently struggling to do so. I've been told that in order to get multiple value, I need to use structs. However I'm struggling to get it to work. Here is what I have so far: Function to be run on button press: struct data { GtkWidget *hash; GtkWidget *hashType; }; static void queue_hash (struct data *dataStruct) { GtkWidget *hashWid = dataStruct->hash; GtkWidget *hashTypeWid =
