Getting Started
The Emulation Workspace
The emulation workspace is the area which emulates the display of the terminal
specified in setup (the VT100 terminal by default) and where work is carried out with
an application. Refer to the section entitled Selecting The Terminal Emulation earlier
in this chapter for details on how to change the emulation.
In Tek mode, the emulation workspace effectively consists of two layers, one lying
on top of the other. One layer, referred to as the dialog area, is used to display
alphanumeric text. The other layer is used to display graphics and graphics text, and
is called the graphics area.
The dialog area is a 'window' into the dialog buffer which is used to store
alphanumeric text. The dialog area may fill the entire emulation workspace or consist
of only two lines. You can specify the size of the dialog buffer and the number of
lines actually displayed in the Dialog Settings dialog box, as described in the Setup
Menus chapter.
When the dialog area is disabled within Tek mode, all incoming alphanumeric text is
directed to the graphics area, providing an emulation of the Tektronix 4014 terminal
which does not support a separate dialog area. In any other terminal emulation mode,
the dialog area is always enabled (there is no separate graphics layer) and all
alphanumeric text is directed to it.
You can toggle the visibility of the dialog area on and off by clicking the DVisib soft
button in the Soft Buttons window. The contents of the dialog buffer can be erased
by clicking the DErase button, and you can erase the contents of the graphics area
and cause all visible segments to be redrawn by clicking the GErase button.
Default Font Sizes
The size of the font used by default when TeemTalk is loaded usually depends on
the type of display adaptor in your system. However, you can specify a different
default font size using the initialization file command defaultFontIndex=# or
-df# command line option, where # is the index of the font as defined in the following
table.
The size of the font for a particular index will vary depending on the terminal
emulation. Specifying an index outside the range for the emulation will cause the
highest valid index number for that emulation to be used. The font sizes are defined
in pixels.
