  • ColorMemo

    We encountered a need to "color code" html tags. That pushed us to development of memo component that would be able to "color" the text it contains. We felt a need in it because RichEdit that comes with Delphi is just too much for us and requires a DLL to be installed ( and the right version of it ). Not to mention that it's too complex for novice users and not flexible enough for advanced ones.

    With version 1.0, we tried to make it very simple and easy to use so novice users can "plug&play" it into their application without any painful reading of manuals. And at the same time it should allow more advanced user to implement any imaginable set of "color coding" rules. Yes, we know it's hard to achieve both goals, and it's up to you judge how we succeeded.

    After it's great success and feedback we received, we were sure about it's easy of use and concentrated our efforts on features requested by users. We rewrote this product with new architecture in mind.
    ColorMemo 2.x now has an editor, new help file, improved demo. Unlimited number of rules can be defined ( even of same type ). Colors can be defined either for each tag or a group of them.

    Small Note: It's not compatible with 1.2, but this gave us an opportunity to make it "so powerful" :)

    Starting from this release, it must be installed using cmemo.pas instead of colormemo.pas ( or *.dcu if you haven't purchased sources ).


    Begin-end: for tagged data. Let's say <;>;blue will paint all tags in blue. Their can be lots of begin / end / color pairs for each tag or a group of them. All the text between Begin and End markers is drawn in your color. This is useful when implementing HTML editors and coloring other text where starting and ending markers are available. For the figure at the left we used " < " and ">" symbols as markers for blue HTML tags. Plus "{" and "}" for grey pascal style comments. And here is what we've got as an output.

    Key-Show: You provide a list of "keywords" and ColorMemo draws them in colors of your choice. That's how Delphis own editor is implemented ( we guess so ).
    You enter keywords or groups of tem and colors to draw them in :
    Very useful for editors of scripting languages or other simple text that has a pre defined set of words to highlight. For the figure at the left we used some words from Object Pascal language as Keywords. And here is what we've got as an output.

    Begin-end-line: for // comments or similar things when everything after
    some symbol(s) are painted in defined color until end of line is found

    Event-draw: You specify an even and it is called for each piece of text that needs to be drawn. Your event then returns text pieces along with colors for them. After that we draw text in colors you supplied. Your event can say :
    "from symbol 1 to 10 draw in green and from 12 to draw in red , etc."
