Is it possible to make a richview's background transparent?

Post by cryingfox »

There may be a panel blow. And I need the richview be transparent. How can I make it work this way?

Take a "snapshot" of whatever is behind RichView (the relevant portion of your panel) and use it as RichView's background image?

Yes, transparency is not supported directly. One of possible solutions is suggested by Michel.

Another solution.
It may be useful if you create a kind of report including TRichView objects. Draw the document into a metafile and display this metafile instead of TRichViewEdit. If you need an inplace editing, place TRichViewEdit over this metafile when the user clicks at this area.

For drawing document into a metafile, see the demo Demos\Delphi\Assorted\Graphics\ToImage\.
Set RVReportHelper.TransparentBackground = True.
