有没有更好的方法在CStatic控件中的第一个单词下划线？

Question

I have a 2D character array lineData and an array of bool s, linesToUnderline . lineData stores just text. linesToUnderline stores a true or a false for each line in lineData . Each line in lineData is being put in a static control (which is created dynamically) in a certain fashion to display to the user.

Now if linesToUnderline[i] = true (for 0 <= i < numLines ), I need to display the line with only the first word underlined and the rest of the text normally.

What I'm talking about looks like:

So currently, what I'm thinking of doing:

1. If linesToUnderline[i] = false, go to step 4.
2. Get the first word from lineData , put it in a static control, set that control's font to underlined.
3. Remove the first word from lineData .
4. Increment starting X position by lineData 's pixel length.
5. Put lineData in a static control starting at a position X, Y.
6. If i < numLines go to step 1.
7. Stop.

What do you think of my method? I feel that there must be a better way to do this. If there is, could someone help me out?

Answer 1

Your proposed method will not work. The control uses only one font at a time (for all its text) and it does not provide a way to append text at X,Y.

You must subclass the control and paint the text yourself in WM_PAINT. Your paint code can provide the necessary features.

Answer 2

This code project article implements a hyperlink control by subclassing a static control. You can use it as a base for doing custom underlining. All you have to do is simplify the code.
