Dialogue Input in the Screen Menu Interface

Dialogue input in the screen menu interface

The full command-line capability is preserved when T/HIS is running in screen-menu mode, and you are free to mix command-line and mouse-driven input at will. There are some situations in which command-line input is more efficient: for example when entering lists of explicit entities.

Commands are entered in the dialogue box:

As this example shows the dialogue box is also used for listing messages, warnings and errors to the screen. It can be scrolled back and forth (its buffer is 200 lines long) to review earlier messages. The following colours are used:

There is a minor limitation when mixing command-line and screen-menu mode: you cannot perform the same function simultaneously in both modes. If you attempt to do so you will get the message:

WARNING: recursive access attempted

And you will not be permitted to continue.

For T/HIS 20.0 onwards, we have now also added the ability to use the Up and Down arrow keys in order to cycle through previously issued commands that you have entered into the Dialogue window. Currently only the last 50 commands are stored in memory. Commands issued after this 50 limit will remove the oldest issued commands first from the list.
