pango markup_markup公式_markup用法(5)

Once you have set the default font, you can change around the appearance of specific blocks of text using Pango markup. This is done by calling the method. The markup below shows how text is customized in Pango. The block of text in the tag specifically overrides some of the default settings made earlier through set_font_description().

                #Set the markup for our pango layout. 
		self.pango_layout.set_markup('<span foreground=\"blue\">This is some sample markup</span> 
<sup>text</sup> that <span style=\"normal\" size=\"small\">is displayed with pango</span>\n\n <u>Current time:</u> ')

The screenshot below shows how the text above shows up after setting the default font earlier and then customizing with the markup.

Yes, in fact some widgets like gtk.Label already have built in methods to set pango markup. This makes the process of creating custom Pango text extremely easy. In fact, if you just want some small or area of text in your activity UI, you might be better served creating a gtk.Label and using the set_markup() method that comes built in for use with Pango. Of course, if labels, tooltips or other widgets are not sufficient for what you are trying to do with your UI, you will have to revert to using more broad-purpose widgets like the gtk.DrawingArea.

Below is some code that creates a label, sets its text to be Pango markup and then adds it to some existing UI widget (called first_page).
