    Overview

    The CSeparator class is an enhancement to standard static text controls that duplicates the look of the Office 97 products' options screens, like Word (pictured).

    This separator element is a nice alternative when you want to avoid really big or nested group boxes, or just look like you're keeping up with Microsoft's ever-changing UI designs. Wink | ;)

    This class is an extension to Hans Buehler's original article "Control for drawing a bevel line." One of the enhancements he mentioned was adding text to horizontal lines, so that's what I've done!

    CSeparator was written with MSVC 5.0. The code will work in Unicode apps, and should compile fine with 6.0 as well.

    Example

    When laying out a vertical separator, make the static control as tall as you want the line to be. The line will be drawn horizontally centered in the control, so it's a good idea to make the control the minimum width of 8 DLUs so you can judge where the line will appear. Vertical separators do not display text.

    When laying out horizontal separators, place your static controls as usual, but make them as wide as you want the horizontal line to be. You can also set the alignment of the text (left, center, or right), and set the No Prefix style if you want. Those are the only static control styles supported at this time. If you do not set the No Prefix style, then you can use a shortcut key (i.e., put a & before a letter) just as with normal static text controls.

    A sample dialog is pictured below, first in the resource editor, and then with the separators in action.

    Each static control that will be used as a separator should have a real unique ID (not IDC_STATIC). Using ClassWizard, create member variables of type CStatic for each separator, and then go to the ClassWizard-generated code and change the type of the variables to CSeparator. That's it!

    Future Enhancements

    I tried for a little while to get vertically-drawn text, but it was pretty tricky to get the text aligned correctly over the line. Drawing the text rotated is no problem (as long as you select a TrueType font into the DC!) but the horizontal position of the text depends on the length of the text. The CSeparator class has some code to draw text vertically, although it is commented out since it doesn't work exactly right. It's just there as a starting point for anyone brave enough to take on the challenge. See the OnPaint() function for the code snippet and some comments.
