How can i set baseUrl only once?

[benyeyeye]

I found the following code for rendering images from relative paths in HTML

self.webPage.setHtml('<img src="image.png"/>', baseUrl=QUrl.fromLocalFile(os.getcwd()+os.path.sep))

However i call setHTML a lot, and would rather be able to set baseURL once rather than adding it as an argument each time. How can i do this?

You always have to set the baseUrl if you want to use setHtml, but if you want to repeat the code then create a method that does it:

class Foo(Bar):
    def __init__(self, ...):
         super().__init(...)
         self._base_url = QUrl()
         self.base_url = QUrl.fromLocalFile(os.getcwd()+os.path.sep)
         self.webPage = ...

    @property
    def base_url(self):
        return self._base_url

    @base_url.setter
    def base_url(self, url):
        self._base_url = url

    def update_html(self, html):
        self.webPage.setHtml(html, self.base_url)

then:

self.update_html('<img src="image.png"/>');
