如何使用PyQt加载图像资源? [英] How to load image resources with PyQt?

问题描述

我的应用程序具有以下结构:

I have this estructure on my application:

|-App
|
|-functions
|
|-ui
|--ui.py
|    
|images
|
|main.py

我有一个包含一些脚本的功能文件夹，以及一个在ui.py文件上包含PyQt生成的代码的ui文件夹.

i have a functions folder with some scripts and a ui folder with the PyQt generated code on the ui.py file.

和一个main.py文件，该文件加载ui.py以显示界面，而ui.py则从根目录的"images"文件夹中加载一些图像.

and a main.py file that loads the ui.py to show the interface and ui.py loads some images from the "images" folder on the root.

如果我直接在python上执行脚本(main.py文件中为double clic)，则不会显示图片.

if I execute my script directly on python (double clic on main.py file), the images wont show..

但是如果我将终端与"python main.py"一起使用，则图像会正确显示.

But if I use the terminal with "python main.py" the images show correctly.

ui.py上的引用类似于:

The references on ui.py are like:

icon.addPixmap(QtGui.QPixmap(_fromUtf8("images/flags/MXN.png"))

推荐答案

使用 Qt设计器资源系统，为图像创建资源文件.

Use the Qt Designer Resource System to create a resource file for the images.

然后使用 PyQt的pyrcc工具来转换Qt资源文件放入python模块.

Then use PyQt's pyrcc tool to convert the Qt resource file into a python module.

NB:python资源模块应与ui文件位于同一目录中.因此，如果您在Qt Designer中创建了资源文件 App/resources.qrc ，则应按如下所示进行转换:

NB: The python resource module should go in the same directory as your ui files. So if you created the resource file App/resources.qrc in Qt Designer, you should then convert it like this:

pyrcc5 -o App/ui/resources_rc.py App/resources.qrc

PySide(Qt4)的等效工具是 pyside-rcc .对于PySide2/PySide6，Qt rcc 工具本身具有生成python输出的选项:

The equivalent tool for PySide (Qt4) was pyside-rcc. For PySide2/PySide6, the Qt rcc tool itself has an option to produce python output:

rcc -g python -o App/ui/resources_rc.py App/resources.qrc

更新:

PyQt6现在已删除了pyrcc工具(请参阅:如何在PyQt6(不包含pyrcc)中提供资源?).

PyQt6 has now removed the pyrcc tool (see: How can resources be provided in PyQt6 (which has no pyrcc)?).
