I want to implement basic spell checking in a Notepad clone project I’m doing. I want to underline misspelled words with a squiggly like like Word does. I think I need to use GDI and draw on the text field, but I’m not sure how to draw on controls.
Thanks
If you’re basing your editor on an edit control (as Notepad does), then I think it’s going to be difficult. By subclassing the edit control window, you could probably augment its
WM_PAINThandling. But the problem is the control doesn’t expose a way for you to find out exactly where a word appears within the control. Thus you won’t know where to draw the squiggle.You might be able to use a Rich Edit control (as WordPad does) and tweak the styling of the misspelled words. I’ve never used Rich Edit, so I can’t help with the details.
