[Demo] Chat codes

Post by Sergey Tkachenko »

1. Simple demo
http://www.trichview.com/support/files/chatcodes.zip

This demo shows how to add text with some codes:
\b - bold on/off
\i - italic on/off
\u - underline on/off
\cRRGGBB - text color
\kRRGGBB - text background color

2. Advanced demo with plain text input

[+] Old version of this demo
https://www.trichview.com/support/files/chatcodes2.zip - for TRichView 17.2 and older)
This demo has almost complete ready-to-use chat window functionality.
In addition to the demo above, it supports the commands:
\f"FONTNAME" - changes font name
\sNN - changes font size to NN points (it's also possible to use one digit \sN followed by non-digit character; if this character is a space, it is not displayed)
This demo supports:
- Emoticons. They can be easily customized, just modify CreateEmoticons procedure. In this demo, bitmaps are used, but you can easily change them to animated gifs.
- URL detection
- message preview as you type.

3. Advanced demo with rich text text input

(10 KiB) Downloaded 2492 times
[+] Old version of this demo
https://www.trichview.com/support/files ... ysiwyg.zip (for Delphi) - for TRichView 17.2 and older)
This demo uses the same commands as the demo above, but the message is typed in TRichViewEdit instead of TEdit.
The demo converts the message to a string (using the codes described above), then this string is parsed and added to the chat window.

I do not think that using font dialog is a good idea.
Ok, it's possible to add a chat code like \f"Times New Roman".
But there are on/off switches like \b, so font depends on commands which were added in the string before this place.

Sorry, I never worked with youtube video.
If you know a control that can play youtube video, you can insert it in TRichView.

I believe you can use Flash ActiveX, loading Chromeless Player in it. (apiplayer.SWF): http://code.google.com/apis/youtube/chr ... l#Overview

This demo breaks with D2009

This demo breaks with Delphi 2009. Specifically it looks like the AddStringWithURLs is doing math as 1 byte characters.
