How to set background color of style to null

[m***@gmail.com]

Hi there,

The subject is poorly worded, but here's what I'm looking for. I set STYLE_DEFAULT properties and then call SCI_STYLECLEARALL. I then add back my custom styles as needed. This works well, but my back color for STYLE_BRACELIGHT is showing as the STYLE_DEFAULT back color which I'd expect. However, if I've called SCI_SETCARETLINEVISIBLE(true) I'd like the back color of any brace highlighting on the current line to match what I've set for SCI_SETCARETLINEBACK. I've tried playing with SCI_SETCARETLINEBACKALPHA without success. Is it possible to set a null back color and have whatever back is drawn by other styles (STYLE_DEFAULT, STYLE_BRACELIGHT) to come through?

Thanks,
Michael

The brace highlight back colour receives precedence as some people use the default foreground colour but a distinctive background colour for brace highlighting so would not be able to see the highlights easily if the caret line colour was dominant.

SCI_SETCARETLINEBACKALPHA overdraws the whole line after the text and backgrounds have been drawn so should be less jarring. Use a strong colour with a low alpha for this - say #008000 with alpha 63 and a light brace highlight style background like #CCCCFF.

If you don't like the alpha approach, use http://www.scintilla.org/ScintillaDoc.html#SCI_BRACEHIGHLIGHTINDICATOR

Excellent, thanks! I find the indicators to be very appealing, visually.
I'll play with this.
