PyQt / PySide中是否有默认图标？

I'm reading a tutorial on PySide and I was thinking , do I need to find my own icons for every thing or is there some way to use some built in icons . That way I wouldn't need to find an entire new set of icons if I want my little gui to run on another desktop environment .

我正在阅读关于PySide的教程,我在想,我是否需要为每件事找到自己的图标,或者是否有某种方法可以使用一些内置图标。这样,如果我想让我的小gui在另一个桌面环境中运行,我就不需要找到一整套新的图标。

What you need is Pyside QIcon.fromTheme function. Basicaly it creates QIcon object with needed icon from current system theme.

您需要的是Pyside QIcon.fromTheme功能。 Basicaly它使用当前系统主题中的所需图标创建QIcon对象。

Usage:

undoicon = QIcon.fromTheme("edit-undo")

undoicon = QIcon.fromTheme(“edit-undo”)

"edit undo" - name of the icon "type"/"function" can be found here

“编辑撤消” - 可在此处找到图标“类型”/“功能”的名称

This works on X11 systems, for MacOSX and Windows check QIcon documentation QIcon.fromTheme

这适用于X11系统,对于MacOSX和Windows,请查看QIcon文档QIcon.fromTheme

Edit Inserting this from the website, since last time it was a broken link.

编辑从网站上插入此内容,因为上次它是一个断开的链接。

static PySide.QtGui.QIcon.fromTheme(name[, fallback=QIcon()])

static PySide.QtGui.QIcon.fromTheme(name [,fallback = QIcon()])

Parameters:

name – unicode

名字 - unicode

fallback – PySide.QtGui.QIcon

后备 - PySide.QtGui.QIcon

Return type:

PySide.QtGui.QIcon

Returns the PySide.QtGui.QIcon corresponding to name in the current icon theme. If no such icon is found in the current theme fallback is returned instead.

返回与当前图标主题中的name对应的PySide.QtGui.QIcon。如果在当前主题中找不到这样的图标,则返回后退。

The latest version of the freedesktop icon specification and naming specification can be obtained here:

可以在此处获取最新版本的freedesktop图标规范和命名规范:

http://standards.freedesktop.org/icon-theme-spec/icon-theme-spec-latest.html

http://standards.freedesktop.org/icon-naming-spec/icon-naming-spec-latest.html

To fetch an icon from the current icon theme:

要从当前图标主题获取图标:
undoicon = QIcon.fromTheme("edit-undo")
Or if you want to provide a guaranteed fallback for platforms that do not support theme icons, you can use the second argument:

或者,如果要为不支持主题图标的平台提供有保证的回退,可以使用第二个参数:
undoicon = QIcon.fromTheme("edit-undo", QIcon(":/undo.png"))
Note

By default, only X11 will support themed icons. In order to use themed icons on Mac and Windows, you will have to bundle a compliant theme in one of your PySide.QtGui.QIcon.themeSearchPaths() and set the appropriate PySide.QtGui.QIcon.themeName() .

默认情况下,只有X11支持主题图标。要在Mac和Windows上使用主题图标,您必须在PySide.QtGui.QIcon.themeSearchPaths()中捆绑一个兼容主题,并设置相应的PySide.QtGui.QIcon.themeName()。

There is another way to access some of the standard builtin icons in PyQt/PySide using the standard pixmap in the default style. For example, the following creates an icon for opening a file:

还有另一种方法可以使用默认样式的标准像素图访问PyQt / PySide中的一些标准内置图标。例如,以下内容创建一个用于打开文件的图标:

self.style().standardIcon(QtGui.QStyle.SP_DialogOpenButton)

For the full list of standard pixmaps, see:

I don't think this is specific to any binding, you can check the qt general documentation

我不认为这是特定于任何绑定,你可以检查qt一般文档

I keep having trouble finding images of the standard icons, so for future reference: http://nukesaq88.hatenablog.com/entry/2013/04/12/005525

我一直无法找到标准图标的图像,以便将来参考:http://nukesaq88.hatenablog.com/entry/2013/04/12/005525

And the code I'm using (PyQt4, Pyside probably similar):

我正在使用的代码(PyQt4,Pyside可能类似):

    # In method of QMainWindow subclass
    stdicon = self.style().standardIcon
    style = QtGui.QStyle
    reload_foo = QtGui.QAction(stdicon(style.SP_BrowserReload), '&Reload', self)

It would be nice if the (obviously auto-generated) Qt docs had pictures in the standardIcons enum table...

如果(显然是自动生成的)Qt文档在standardIcons枚举表中有图片会很好...

In PyQt5, here's a simple example of creating a push button with the play icon:

在PyQt5中,这是一个使用播放图标创建按钮的简单示例:

play_button = QtGui.QPushButton('Play video')
play_button.setIcon(QtGui.QApplication.style().standardIcon(QtGui.QStyle.SP_MediaPlay))

The Qt5 documentation provides a list of the possible SP ("Standard Pixmap") icons. See enum QStyle::StandardPixmap here: http://doc.qt.io/qt-5/qstyle.html

Qt5文档提供了可能的SP(“标准Pixmap”)图标列表。请参阅枚举QStyle :: StandardPixmap:http://doc.qt.io/qt-5/qstyle.html

Another PyQt5 example using the standard icons (eqzx's answer didn't work for me):

使用标准图标的另一个PyQt5示例(eqzx的答案对我不起作用):

 from PyQt5.QtWidgets import QApplication, QStyle
 from PyQt5.QtGui import QIcon

 desktop_icon = QIcon(QApplication.style().standardIcon(QStyle.SP_DesktopIcon)

in PyQt, the window icon is by default the Qt logo. I think you will have to find your own icons for things inside the gui.

在PyQt中,窗口图标默认为Qt徽标。我想你必须在gui内找到你自己的图标。
