Chrome扩展窗口能否程序化修改图标？Crouton窗口改标求助

Hey there, let's work through this icon customization issue you're hitting. I've messed around with Crouton and xiwi on Chrome OS a bunch, so here are a couple of reliable ways to get custom icons on your Crouton app windows:

1. Pass the --icon Parameter Directly to Xiwi #

The simplest fix is to leverage xiwi's built-in support for custom icons. When you launch your Crouton program via xiwi from your Chrome app, just add the --icon flag with the path to your custom icon file.

For example, if you're launching a terminal app, your command would look like this:

xiwi --icon=/mnt/chromeos/MyFiles/icons/terminal-custom.png gnome-terminal

• Make sure the icon path is accessible from your Crouton environment. The /mnt/chromeos/MyFiles/ directory is shared between Chrome OS and Crouton, so storing your icons there is a safe bet.
• Stick with PNG icons and use standard sizes (16x16, 32x32, 48x48) to ensure they display correctly across Chrome OS's UI.

2. Modify the Crouton App's Desktop File #

If you prefer a more permanent solution, you can edit the .desktop file of the Linux app you're launching in Crouton. This way, every time you start the app via xiwi, it will use your custom icon automatically.

Here's how to do it:

• Open a Crouton terminal and navigate to the system applications directory:

  cd /usr/share/applications
  

• Find the .desktop file for your app (e.g., firefox.desktop for Firefox) and open it with a text editor like nano:

  nano firefox.desktop
  

• Look for the line starting with Icon=. Replace the existing path with your custom icon's path (again, using the shared Chrome OS directory works well):

  Icon=/mnt/chromeos/MyFiles/icons/firefox-custom.png
  

• Save the file (Ctrl+O in nano, then Enter) and exit (Ctrl+X). Now when you launch the app via xiwi from your Chrome app, it will use the new icon.

Why Your Previous Attempts Didn't Work #

Just to clarify why the methods you tried didn't do what you wanted:

• chrome.browserAction.setIcon only affects the extension's toolbar icon in Chrome, not the actual window of the Crouton app.
• The icon parameter in chrome.windows.create only works for windows created directly by Chrome (like extension popups or tab windows). Xiwi creates windows via a native Linux process, so Chrome's API can't override that icon setting directly.
• chrome.app.window.create is exclusive to packaged Chrome Apps, not regular extensions—but as you saw, Crouton runs as a native process, so wrapping it in an app window isn't necessary when you can use xiwi's own flags.
