Using multiple QSyntaxHighlighter in one QPlainTextEdit

Question

I wrote two syntaxes: one for CSS and one for HTML. They work well.

But I want to put CSS code in the HTML code (inside the <style> tag), so I want to be able to use multiple QSyntaxHighlighter in one QPlainTextEdit.

Is there a way to do what I want? I cannot create two QSyntaxHighlighter objects in the same QPlainTextEdit, because only the second object will be used.

Thanks.

You will need to independently switch between different selection modes, within the same luminance syntax.

I would start with your HTML shortcut, as it should be able to tell when you are in the <style> . Use setCurrentBlockState to mark this block as CSS and delegate it to CSS rendering.

The basic idea is illustrated in the QSyntaxHighlighter docs (switching between comment / code modes) and an example.
