| 43 | |

| 44 | TkCon requires Tk8.0+. Since TkCon is meant to behave like the original Tk |
|---|
| 45 | console, it does not separate itself from the environment (it does not use |
|---|
| 46 | send to function, except when attached to foreign Tk interpreters). This |
|---|
| 47 | means that it can be can be altered or destroyed by any sourced |
|---|
| 48 | applications, and it will respond to an application's 'exit' call by |
|---|
| 49 | exiting (by default, slave consoles will only close themselves instead of |
|---|
| 50 | exiting the entire TkCon environment). However, the widget tree of TkCon |
|---|
| 51 | is hidden from the user environment. |
|---|
| 52 | <P> |
|---|
| 53 | |
|---|
| 54 | Since TkCon is built for cross-platform capability, <font color=#FF0000>in |
|---|
| 55 | Unix/Windows environments it does not have tty/shell behavior</font>. This |
|---|
| 56 | means programs like <CODE>vi</CODE> and <CODE>less</CODE> (those that rely |
|---|
| 57 | on tty/shell settings) will not function appropriately (currently they may |
|---|
| 58 | hang TkCon). Programs like <CODE>ls</CODE> and <CODE>more</CODE> will just |
|---|
| 59 | spit output to the TkCon screen without any special control or formatting |
|---|
| 60 | (note that <CODE>ls</CODE> has been rewritten for TkCon). You also do not |
|---|
| 61 | get any job (process) control outside of what tcl normally can provide. |
|---|
| 62 | Currently there is no way to handle <CODE>stdin</CODE> input. |
|---|
| 63 | <P> |
|---|
| 64 | |
|---|
| 65 | When connecting to non-Tcl Tk interpreters (ie - PerlTk, SchemeTk, ...), |
|---|
| 66 | you must use the syntax of the target environment. See my |
|---|
| 67 | <A HREF="nontcl.html">notes on using other Tk-embedded languages</A> for |
|---|
| 68 | more info. |
