i need to write a couple of lines of text and when user clicks one, an image is shown. Thus, they are much like text links in web browsers. How to?
in Paint(),
w.DrawRect(GetSize(), SColorFace());
w.DrawText(0, 0, "Graphical introduction", Arial(30).Underline(), Blue);

Then how to determine the text's area so that I know user clicks on it? Font::GetHeight() may be working, but how about the width? FontInfo::GetWidth(int) seems okay, but i'll have to count the charcters one by one. Is there an easy way please? thank you.

Use RichTextView or RichTextCtrl and WhenLink.

See QTF docs about how to defined links in QTF text.

i thought of using controls like RichTextView, but i thought the border around the control could not be hidden.
Thanks to Mirek, I'm now using RichTextCtrl.
